    Of the Federal Circuit, sitting by designation.
    TORRUELLA, Circuit Judge. Defendant-Appellant José Tiru-
    Plaza ("Tiru") appeals from the district court's denial of his
    motion to suppress the firearm discovered when a police officer
    pat-frisked him during a traffic stop.
    After stopping a car -- in which Tiru was a passenger --
    for a traffic infraction, officers from the Puerto Rico Police
    Department, evidently suspecting that the car might have been
    stolen, ordered the driver to exit the vehicle and open the hood to
    permit inspection of the vehicle identification number (the "VIN")
    stamped on the engine block.         When the driver complied, the
    movement revealed a gun tucked into his waistband.       The officers
    then detained the driver, ordered Tiru to exit the vehicle, and
    pat-frisked him, revealing a firearm hidden in Tiru's waistband.
    Subsequently, Tiru was placed into custody and charged with being
    a felon in possession of a firearm.      He sought to suppress the gun
    as the fruit of an illegal search.         The district court denied
    Tiru's motion, and he now appeals.       Concluding that the officers
    had an objectively reasonable basis to frisk Tiru, we affirm.
    I.   Background
    A.   The Traffic Stop and Frisks
    We present the facts as found in the evidentiary hearing
    and in the matter "most compatible" with the district court's
    ruling, consistent with record support.         See United States v.

    McGregor, 
    650 F.3d 813
    , 816 (1st Cir. 2011) (citing United States
    v. Dancy, 
    640 F.3d 455
    , 457-58, 460-61 (1st Cir. 2011)).1
    On March 10, 2012, at around 11:00 p.m., Officers José
    Casiano-García   ("Officer   Casiano")   and   Edwin   Martínez-Vargas
    ("Officer Martínez") spotted a Mitsubishi Lancer driving down a
    road in Yauco, Puerto Rico. The car's driver, Jenson Morales-Ramos
    ("Morales"), was accompanied by Tiru and two young women.         The
    officers -- seeing the metal glint of a disengaged buckle over
    Morales's shoulder -- concluded that the car's occupants were not
    wearing seat belts.
    When the officers turned on their lights to signal that
    the car should pull over, Morales failed to stop immediately.2
    After traveling only a short distance, and without speeding up or
    taking evasive action, however, he obeyed the officers' command.
    After approaching the vehicle, Officer Casiano asked Morales for
    his driver's license and registration.    Morales could not provide
    a driver's license, and he handed the officer a photocopy of the

    Though Tiru disputes some of these facts, "[w]e summarize the
    facts as found by the district court in its denial of [the
    defendant's] motion to suppress, which are consistent with record
    support and are not clearly erroneous," and "[w]e supplement that
    description with testimony from the record."

    (internal citations omitted).

    The highway did not have a shoulder, and Morales continued to
    drive until the first available exit.
    -3-
    car's original registration3 on which the VIN could not be made
    out.   The illegible registration and failure to provide a license
    gave rise to some suspicion that the car may have been stolen.4           On
    that basis, Officer Casiano asked Morales to exit the vehicle and
    open the hood for purposes of inspecting the VIN on the car's
    engine.   When Morales obliged, the resulting movement caused his
    shirt to lift up and revealed a green pistol grip in his waistband.
    Seeing   the   gun,   Officer   Casiano   yelled   "arma"5   and
    ordered Morales to place his hands on the hood of the vehicle.
    Having been alerted to the presence of a firearm by his partner,
    Officer Martínez ordered Tiru to exit the vehicle and submit to a
    pat-frisk.    When Officer Martínez ran his hands along Tiru's waist
    he felt a hard object that he believed could be a weapon, inserted
    two fingers under his waistband, and extracted a black pistol.
    Tiru was then taken into police custody.         After the arrival of two
    3
    Morales had borrowed the vehicle while his own car was being
    repaired. The car's owner, who ran a rental business, explained
    that he always keeps original registrations on file in his office
    and places copies in his rental vehicles.
    4
    Although the officers testified that their suspicions were
    further raised because the VIN on the car's doorjamb had been
    removed, this testimony was not credited by the district court.
    Tiru introduced photos, taken after his arrest, showing an intact,
    17-character VIN on a painted white surface.

    more police officers, the female passengers were also detained,
    although they were later released without charges.6
    B.   Denial of Tiru's Motion to Suppress His Firearm
    Tiru was indicted for being a felon in possession of a
    firearm, in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2).   He
    filed a motion to suppress the firearm evidence, principally
    arguing that: (1) the officers lacked any reasonable suspicion to
    stop the vehicle or to order Morales to open the hood, requiring
    suppression of the gun as fruit of an unlawful search; and (2) even
    if the initial stop and subsequent frisk of Morales were legal, the
    officers lacked any reasonable suspicion that Tiru was dangerous or
    engaged in criminal activity, making his pat-frisk unlawful.
    The case was referred to a magistrate judge, who held an
    evidentiary hearing on October 29, 2012.    The magistrate judge's
    report and recommendation concluded that the initial traffic stop
    was lawful, and that Tiru lacked standing to challenge the legality
    6
    One of the car's female passengers offered testimony for the
    defense contradicting the officers' version of events in certain
    respects. She stated that after the officers approached the car
    and asked for Morales's license and registration, they asked
    Morales if he "liv[ed] out there" -- presumably referencing a
    nearby public housing project. The officers then pulled out their
    weapons, ordered all four occupants from the car, and frisked
    Morales. An officer "st[]uck his hand down [Morales's] pants, and
    he pulled out a gun, and he started shouting "[g]un." Another two
    officers arrived in a separate patrol car, and "they searched
    [Tiru]."   Thus, the testimony offered by the defense, though
    differing in some respects from the government's narrative, was
    consistent with the government's evidence that Tiru was pat-frisked
    only after the officers discovered Morales's firearm.
    -5-
    of the officer's attempt to search under the vehicle's hood.
    However, the magistrate judge ultimately found that, under a
    totality-of-the-circumstances        test,    there    was    no   objectively
    reasonable basis to suspect that Tiru was armed or dangerous.                The
    report therefore recommended suppression.
    The district court disagreed with the magistrate judge's
    conclusion as to the totality of the circumstances surrounding
    Tiru's pat-frisk. The district court found that certain "facts are
    undisputed in this case": the young age7 and number of occupants in
    the car (four); the late hour (11:00 p.m.); Morales's failure to
    immediately pull over and stop the car when prompted to do so by
    the police officers; and the discovery of Morales's gun.               On the
    basis of these factors, the district court found an objectively
    reasonable basis for the officer's frisk of Tiru.              The court thus
    denied the motion to suppress.
    Tiru pleaded guilty to being a felon in possession of a
    firearm and was sentenced to thirty-three months' imprisonment and
    a   supervised-release   term   of    three   years.         Nevertheless,    he
    reserved the right to seek appellate review of the district court's
    decision to deny suppression.        He now exercises that right.
    7
    Officer Casiano testified that Morales, the driver, was "a young
    man," and that one of the female passengers was "a young lady."
    Officer Martínez also testified that Morales was "[a]nother young
    man."

    II. Discussion
    On an appeal from a denial of a motion to suppress, our
    review of the district court's decision is bifurcated.                                First,
    factual conclusions and credibility determinations are reviewed
    only for clear error.            United States v. Camacho, 
    661 F.3d 718
    , 723
    (1st       Cir.    2011).       Under      this       clear-error    review,     we    grant
    significant         deference       to    the   district     court,      overturning     its
    findings only if, after a full review of the record, we possess "a
    definite and firm conviction" that a mistake was made.                          
    McGregor, 650 F.3d at 820
    (citing United States v. Woodbury, 
    511 F.3d 93
    , 96
    (1st Cir. 2007)); see also United States v. Cruz-Jiménez, 
    894 F.2d 1
    ,     7    (1st        Cir.    1990)      ("Where       there    are     two   competing
    interpretations of the              evidence, the district court's choice of
    one of them cannot be clearly erroneous.").
    Second, in contrast, we review legal conclusions --
    including         the    district    court's      probable       cause    and   reasonable
    suspicion determinations, as well as its ultimate decision to grant
    or deny the motion to suppress -- de novo.                          Camacho, 661 F.3 at
    723; United States v. Crespo-Ríos, 
    645 F.3d 37
    , 41 (1st Cir. 2011).
    In   assessing          these   legal      conclusions,      however,      we   also    give
    appropriate weight to the inferences drawn by the district court
    and the on-scene officers, recognizing that they possess the
    advantage of immediacy and familiarity with the witnesses and
    events. See United States v. Dapolito, 
    713 F.3d 141
    , 147 (1st Cir.
    -7-
    2013) (citing Ornelas v. United States, 
    517 U.S. 690
    , 698-99
    (1996)); United States v. Smith, 
    423 F.3d 25
    , 35 (1st Cir. 2005)
    ("De novo review in this particular context is not unmindful of the
    district court's reasoning (nor the reasoning of the officers)
    . . . .").
    A.   The Fundamentals: the Fourth Amendment and Terry Stops
    The Fourth Amendment protects an individual's right to be
    free from unreasonable searches and seizures by the government.
    See U.S. Const. amend. IV; see, e.g., Terry v. Ohio, 
    392 U.S. 1
    , 9
    (1968) (quoting Elkins v. United States, 
    364 U.S. 206
    , 222 (1960)).
    Warrantless searches are per se unreasonable, unless they fall
    within a well-defined and specifically enumerated exception to the
    warrant requirement.     See Coolidge v. New Hampshire, 
    403 U.S. 443
    ,
    454-55 (1971); see also 
    Camacho, 661 F.3d at 724
    (citing Arizona v.
    Gant, 
    556 U.S. 332
    , 338 (2009)). The Fourth Amendment's protection
    is ensured by, among other means, the exclusionary rule, which in
    certain circumstances requires suppression of evidence that is the
    product of an unlawful search or seizure.      See, e.g., 
    Terry, 392 U.S. at 12
    ; 
    Camacho, 661 F.3d at 724
    .
    Included in the Fourth Amendment's protective ambit are
    Terry stops -- those "brief investigatory stops of persons or
    vehicles that fall short of traditional arrest."     United States v.
    Arvizu, 
    534 U.S. 266
    , 273 (2002); see also 
    Camacho, 661 F.3d at 724
    ("The protections of the Fourth Amendment apply not only to
    -8-
    traditional arrests, but also to those brief investigatory stops
    generally known as Terry stops."); United States v. Chhien, 
    266 F.3d 1
    ,   5   (1st   Cir.   2001)   (recognizing   that   a   traffic   stop
    constitutes a Fourth Amendment seizure of both the vehicle and its
    occupants (citing Delaware v. Prouse, 
    440 U.S. 648
    , 653 (1979)).
    Such stops are reasonable, and consequently do not offend the
    Fourth Amendment, only where officers have "a reasonable suspicion
    supported by articulable facts that criminal activity 'may be
    afoot.'"    United States v. Sokolow, 
    490 U.S. 1
    , 7 (1989) (quoting
    
    Terry, 392 U.S. at 30
    )); 
    Camacho, 661 F.3d at 724
    -25 (describing
    the reasonable suspicion required to validate a Terry stop).
    During a valid Terry stop, a police officer may perform pat-frisks
    or search a car's interior for weapons if the officer "has some
    articulable, reasonable suspicion that the persons stopped may be
    dangerous."     
    McGregor, 650 F.3d at 820
    ; see also United States v.
    Ruidíaz, 
    529 F.3d 25
    , 32-33 (1st Cir. 2008) (holding that, during
    a traffic stop and when an officer has concern for his own safety,
    the officer may "order a passenger out of the car as a security
    measure" and may perform a protective pat-down once he "has formed
    a reasonable belief that a detained person may be armed and
    dangerous").
    Reasonable suspicion is a less exacting requirement than
    probable cause, but requires "something more than an inchoate and
    unparticularized suspicion or 'hunch.'"          
    Sokolow, 490 U.S. at 7
    -9-
    (quoting 
    Terry, 392 U.S. at 27
    ) (internal quotation marks omitted);
    see also 
    Chhien, 266 F.3d at 6
    (same).               In determining whether
    reasonable suspicion existed, we apply an objective standard,
    rather than assessing the subjective intent of an individual
    officer,    and    we   appropriately    consider    the   "totality     of    the
    surrounding circumstances."        
    Ruidíaz, 529 F.3d at 29
    .
    This    reasonableness      inquiry    deals   with     "degrees    of
    likelihood, not . . . certainties or near certainties," United
    States v. Arnott, No. 13-1881, 
    2014 WL 2959288
    , at *3 (1st Cir.
    July   2,   2014),      and   ultimately    we    must   make   a   "practical,
    commonsense judgment" based on the intricacies of each case.
    
    Chhien, 266 F.3d at 6
    . In so doing, we appropriately grant respect
    to the ability of trained and experienced police officers8 to draw
    from the attendant circumstances inferences that would "elude an
    untrained person."        United States v. Cortez, 
    449 U.S. 411
    , 418
    (1981); see also 
    Ruidíaz, 529 F.3d at 29
    (same).                We also seek to
    "balance 'the nature and quality of the intrusion on personal
    security against the importance of the governmental interests
    alleged to justify the intrusion.'" 
    Chhien, 266 F.3d at 6
    (quoting
    United States v. Sowers, 
    136 F.3d 24
    , 27 (1st Cir. 1998)).

    At the suppression hearing, Officer Casiano testified that he
    had worked as a police officer for eighteen years; Officer Martínez
    testified that he had worked for the Puerto Rico Police Department
    for approximately seventeen years and six months.
    -10-
    Arguing that evidence of his firearm should have been
    suppressed, Tiru principally levies three interrelated arguments.
    First,   Tiru    asserts   that   the   police   illegally   extended   his
    detention when they ordered Morales, the driver, to open the hood
    of the car.     Second, he maintains that the gun was discovered when
    the police searched him pursuant to an unlawful arrest.         Third, he
    argues that the police officers were not justified in pat-frisking
    him pursuant to a valid Terry stop because none of the factors that
    the district court relied upon were particular to him.         We address
    each argument in turn.
    B.   Did the Police Illegally Extend Tiru's Detention by Ordering
    Morales to Open the Hood of the Car?
    Tiru argues that the police officers unlawfully extended
    his detention during the traffic stop by searching under the hood.9
    See, e.g., United States v. Acosta-Colón, 
    157 F.3d 9
    , 14 (1st Cir.
    1998) ("Terry was intended to carve out an exception to the
    probable cause requirement only for relatively brief, non-arrest
    detentions; plainly, a seizure that is, de facto, tantamount to an
    arrest cannot fit within that exception.").         In assessing whether
    9
    On appeal, Tiru does not dispute the district court's
    determination that he lacked standing to challenge any search of
    Morales's person or of the car itself.        See, e.g., Rakas v.
    Illinois, 
    439 U.S. 128
    , 148-49 (1978) (establishing that a
    vehicle's passenger generally does not have an expectation of
    privacy over areas like a car's glove compartment, trunk, or under-
    seat area).    Instead, Tiru argues that the police illegally
    extended the traffic stop as to Tiru himself when they asked
    Morales to open the hood of the car.
    -11-
    the duration of a Terry stop is so long that it becomes unlawful,
    there is no bright-line rule.   United States v. Pontoo, 
    666 F.3d 20
    , 30 (1st Cir. 2011) (citing Florida v. Royer, 
    460 U.S. 491
    , 506-
    07 (1983)).    Rather, we apply a totality-of-the-circumstances
    approach, considering, among other things, "the length of the
    detention, the restrictions placed on an individual's personal
    movement, the force (if any) that was exerted, the information
    conveyed to the detainee, and the severity of the intrusion."
    
    Sowers, 136 F.3d at 28
    .
    Morales failed to provide the police officers with a
    driver's license and a legible car registration.10     Under these
    circumstances, it was reasonable for the officers to suspect that
    the car might have been stolen.        See 
    Terry, 392 U.S. at 27
    (allowing officers to rely on "reasonable inferences . . . draw[n]
    from the facts in light of [their] experience").     Based on that
    suspicion, Officer Casiano asked Morales to get out of the car and
    open the hood, in order to check the VIN on the car's engine and
    compare it with the VIN number on the dashboard. This would enable
    the officer to determine whether there was an inconsistency between
    the numbers, indicating a stolen car, or to check the VIN numbers
    10
    The district court did not make an express determination
    regarding whether the registration was in fact illegible, but we
    view the record in light most favorable to the court's ruling on
    suppression. See Arnott, 
    2014 WL 2959288
    , at *4 ("Although the
    district court made no express findings on this point, we must view
    the record and the reasonable inferences extractable therefrom in
    the light most favorable to the court's suppression ruling.").
    -12-
    with   a    stolen    vehicles   database.         The   officers'    suspicion
    eventually led them to send the car to the police department's
    Stolen Vehicles Division for inspection.
    Tiru's argument focuses on the duration of the stop; he
    suggests that the time it took to have Morales open the hood
    unreasonably elongated the initial Terry stop.11             We cannot agree.
    "The appropriate length of a Terry stop is gauged by whether the
    officer diligently pursued a reasonable investigative approach
    calculated to ensure officer safety and, at the same time, confirm
    or dispel his suspicions." 
    Pontoo, 666 F.3d at 31
    . Here, although
    nothing in the record describes the precise length of time it took
    for Morales to exit the vehicle, approach its front, and open the
    hood, no reasonable reading of the facts could allow us to conclude
    that the duration of time in which these events occurred was
    anything but brief. Cf. United States v. Owens, 
    167 F.3d 739
    , 748-
    49   (1st   Cir.     1999)   (finding    a     fifty-five-minute     Terry   stop
    reasonable under the circumstances).
    Moreover, whatever its length, this sequence of events
    occurred immediately after the officers began to suspect that the
    car might be stolen, and it was a "reasonable investigative
    approach" intended to dispel that suspicion. Flowers v. Fiore, 359
    11
    We note that the other relevant factors, such as the degree of
    police intervention, cut strongly against Tiru's claim. During the
    time that Morales exited the car and sought to open the vehicle's
    hood, Tiru remained in the back seat and was not subject to any
    officer intervention.
    -13-
    F.3d 24, 31 (1st Cir. 2004) (holding the duration of a stop to be
    reasonable where the officers diligently sought to dispel their
    suspicions); cf. United States v. Place, 
    462 U.S. 696
    , 703 (1983)
    (balancing the intrusiveness of a search against the governmental
    interest served); United States v. Ware, 
    457 F.2d 828
    , 829 (7th
    Cir. 1972) (validating a search under the hood "where the officer
    has a legitimate reason to identify the automobile"); United States
    v. Dadurian, 
    450 F.2d 22
    , 25 (1st Cir. 1971) (finding a "reasonable
    ground" to inspect a VIN under an engine based on a discrepancy
    between the vehicle's two visible VINs).    Therefore, this argument
    necessarily fails, and we find that the officers did not unlawfully
    extend Tiru's detention.
    C.   Was Tiru Searched Pursuant to an Unlawful Arrest?
    Tiru next argues that the pat-frisk conducted by Officer
    Martínez was not a Terry frisk at all, but rather was a search
    incident to an unlawful arrest.       Citing testimony from Officer
    Martínez, Tiru claims that after discovering Morales's gun the
    officers immediately placed all of the vehicle's occupants under
    arrest, despite the absence of probable cause that he or the female
    passengers had engaged in a crime.12       Tiru bases this argument
    12
    This argument was not directly raised before the district court,
    which is a proper grounds for waiver. See, e.g., United States v.
    Oquendo-Rivas, 
    750 F.3d 12
    , 16-17 (1st Cir. 2014). Because the
    government did not raise a claim of waiver, however, we skip over
    any possible waiver argument and we treat the claim on its merits.
    See Knight v. United States, 
    37 F.3d 769
    , 772 n.2 (1st Cir. 1994)
    ("[A]s the government has not objected on this ground, and as the
    -14-
    entirely on Officer Martínez's testimony in response to being asked
    why he frisked Tiru; Martínez replied that after his partner
    discovered a firearm on Morales "everyone in the vehicle [was]
    placed under arrest."     Tiru's argument on this point fails to
    persuade.
    Whatever the intended meaning of Officer Martínez's
    statement, the facts do not support a claim that Tiru was placed
    under arrest prior to being frisked.       After the discovery of
    Morales's firearm, the progression of events -- as explicitly found
    by the district court -- was as follows: Tiru was asked to step out
    of the vehicle, while the two female passengers remained inside;
    Officer Martínez pat-frisked Tiru; the frisk revealed a weapon; and
    only then was Tiru handcuffed and detained.   See 
    Camacho, 661 F.3d at 723
    (recognizing that factual findings related to a motion to
    suppress are reviewed by our court only for clear error).    These
    facts do not support the claim that, prior to the frisk of Tiru, he
    was placed under formal or even de facto arrest by Officer Casiano.
    We have held that there is no "scientifically precise
    formula" demarcating the line between investigatory Terry stops and
    a de facto arrest.   United States v. Zapata, 
    18 F.3d 971
    , 975 (1st
    Cir. 1994).   Instead, we have said that "a de facto arrest occurs
    when 'a reasonable man in the suspect's position would have
    claim fails in any event, we overlook that it was not raised
    below.").
    -15-
    understood his situation . . . to be tantamount to being under
    arrest.'"      United States v. Jones, 
    700 F.3d 615
    , 624 (1st Cir.
    2012) (quoting 
    Zapata, 18 F.3d at 975
    ).               As outlined above, the
    facts here do not meet that standard.               Prior to the discovery of
    Morales's gun, Tiru was seated in the back seat of the car during
    a traffic stop for a traffic violation -- we do not think that a
    reasonable person in Tiru's position would have considered himself
    to be under arrest at that time.            See 
    id. Nor do
    we think that, in
    the brief instant between the discovery of Morales's gun and the
    pat-frisk of Tiru, a reasonable person in Tiru's shoes would have
    considered himself to be under arrest. See 
    id. Therefore, we
    turn
    to   examine    the    validity   of    the    initial   Terry   stop   and    the
    reasonableness of the officers' actions thereafter.
    D.   The Terry Stop and Subsequent Pat-Frisk of Tiru
    Our review of an investigatory Terry stop proceeds in two
    steps.    First, we assess whether the stop was "justified [by
    reasonable suspicion] at its inception."              
    Pontoo, 666 F.3d at 26
    .
    Second, we ask whether the officers' actions during the stop bear
    a    reasonable       relationship     to     the   circumstances   originally
    justifying the stop.        United States v. Henderson, 
    463 F.3d 27
    , 45
    (1st Cir. 2006).          Within this second step, we recognize that
    information gained subsequent to the initial stop may provide a
    "'basis   for     expanding   [the     officers']     investigation.'"        Id.;
    
    Chhien, 266 F.3d at 6
    ("[W]hile an officer's actions must bear some
    -16-
    relation to the purpose of the original stop, he may shift his
    focus and increase the scope of his investigation by degrees if his
    suspicions mount during the course of the detention."); 
    Sowers, 136 F.3d at 27
    (requiring that "the actions undertaken by the officer
    following the stop [be] reasonably responsive to the circumstances
    justifying the stop in the first place, as augmented by information
    gleaned by the officer during the stop").
    1.   Legitimacy of the Initial Terry Stop
    Although he disputed this fact in his motion to suppress,
    Tiru's appeal does not challenge the district court's factual
    determination that the car's occupants were not wearing their seat
    belts.   We agree with the district court's determination that this
    traffic infraction was sufficient to justify the initial stop. See
    Whren v. United States, 
    517 U.S. 806
    , 819 (1996) ("[T]he officers
    had probable cause to believe that petitioners had violated the
    traffic code.   That rendered the stop reasonable under the Fourth
    Amendment . . . ."); 
    McGregor, 650 F.3d at 820
    ("An officer can
    stop a car if he sees a driver commit a traffic offense, even if
    the stop is just an excuse to investigate something else.");
    
    Chhien, 266 F.3d at 6
    ("[T]he appellant does not question the
    legitimacy of the initial detention: [the officer] clearly had
    cause to stop him for tailgating and operating an automobile
    equipped with blue-tinted lights.").
    -17-
    2.   Reasonableness of the Officer's Subsequent Actions
    Resolution of this case rests on determining whether the
    officers' actions subsequent to the initial stop, which culminated
    in Tiru's pat-frisk, were a reasonable investigatory response
    intended to dispel suspicions related to the evolving circumstances
    of that stop.     See 
    Ruidíaz, 529 F.3d at 29
    (disavowing a test that
    treats Terry stops like a "snapshot of events frozen in time and
    place"); 
    Chhien, 266 F.3d at 6
    (allowing for officers to respond
    reasonably to the "emerging tableau" of facts observed after an
    initial stop).
    To begin, it is clear that the officers' request that
    Morales exit the vehicle was permissible.       Pennsylvania v. Mimms,
    
    434 U.S. 106
    , 111 n.6 (1977) ("We hold only that once a motor
    vehicle has been lawfully detained for a traffic violation, the
    police officers may order the driver to get out of the vehicle
    without   violating     the   Fourth     Amendment's   proscription   of
    unreasonable searches and seizures."); United States v. Coplin, 
    463 F.3d 96
    , 102 (1st Cir. 2006) ("[A] police officer may, as a matter
    of course, require the driver of a car lawfully stopped for a
    suspected traffic violation to step out of his vehicle." (citation
    omitted)).
    Similarly, the officers' request for Tiru to exit the
    vehicle was also permissible. Given the scope of Tiru's appeal, we
    appropriately focus on the events occurring subsequent to the
    -18-
    officers' request to view the engine.               When Morales attempted to
    open the vehicle's hood, Officer Casiano noticed that Morales had
    a visible gun in his waistband.               In light of this discovery,
    Officer    Martínez's      request     that   Tiru     exit    the    vehicle   was
    reasonable and was responsive to the needs of officer safety.
    
    Ruidíaz, 529 F.3d at 32
    ("When a Terry stop is effected in
    connection with a traffic violation and an officer's concern for
    his own safety is implicated, it is within the officer's authority
    to order a passenger out of the car as a security measure."); see
    also Maryland v. Wilson, 
    519 U.S. 408
    , 414-15 (1997) (holding that
    "an officer making a traffic stop may order passengers to get out
    of the car pending completion of the stop," because "the motivation
    of a passenger to employ violence to prevent apprehension of such
    a crime is every bit as great as that of the driver" and that
    "danger to an officer from a traffic stop is likely to be greater
    when there are passengers in addition to the driver in the stopped
    car");    
    McGregor, 650 F.3d at 820
       (stating    that    an   officer
    conducting a traffic stop can "order the occupants out of the
    auto").     Indeed, Officer Martínez testified that when Officer
    Casiano yelled, "weapon," Martínez "immediately feared for my life
    and for the life of my fellow officer, and for the lives of the
    people in the car."
    Tiru   and    the    government       disagree    about   whether   the
    subsequent pat-frisk was undergirded by a reasonable suspicion that
    -19-
    Tiru was dangerous.   See 
    McGregor, 650 F.3d at 820
    (allowing for
    officers to pat-frisk a car's occupants after a traffic stop when
    there is an "articulable, reasonable suspicion that the persons
    stopped may be dangerous"); 
    Pontoo, 666 F.3d at 30
    ("In a world
    fraught with peril, officer safety must have a place at the
    forefront of police work.    It follows logically that a pat-frisk
    may accompany an investigatory stop whenever an officer has reason
    to believe that the suspect is armed and dangerous." (internal
    quotation marks and citation omitted)).
    Tiru asserts that the district court's denial of his
    motion to suppress relied only on general or environmental factors
    -- for example, his youth and the time of night -- that lacked all
    bearing to Tiru specifically.        In Tiru's estimation, reliance
    solely on these facts is an insufficient ground for a search, and
    it reveals a telling absence of any reasonable suspicion that he
    was   dangerous.   Tiru   claims    that   his   frisk   was   necessarily
    unreasonable, as any suspicion was based merely on his proximity to
    Morales.   In support of this position, Tiru asks us to reject what
    he deems to be a "theory of guilt by association," relying on the
    Supreme Court's decision in Ybarra v. Illinois, 
    444 U.S. 85
    (1979),
    for the proposition that "a person's mere propinquity to others
    independently suspected of criminal activity does not, without
    more, give rise to probable cause to search that person."           
    Id. at 91.
    -20-
    Ybarra, however, is readily distinguished from the case
    at bar. In Ybarra, the police officers "knew nothing in particular
    about" the defendant prior to pat-frisking him, "except that he was
    present, along with several other customers, in a public tavern at
    a time when the police had reason to believe that the bartender
    would have heroin for sale."       
    Id. No firearms
    or other weapons
    were found prior to the frisk of Ybarra.        
    Id. at 87-89.
      Other than
    their mere presence in the same bar, there were no facts connecting
    Ybarra to the bartender suspected of selling heroin.            
    Id. Under those
    circumstances, the Supreme Court held that "[t]he initial
    frisk of [the defendant] was simply not supported by a reasonable
    belief that he was armed and presently dangerous, a belief which
    this Court has invariably held must form the predicate to a patdown
    of a person for weapons."       
    Id. at 92-93.
    Here,   we   are   confronted   with    markedly    different
    circumstances than those presented in Ybarra. Viewing the facts of
    the instant case in their totality, we are unconvinced by Tiru's
    argument.    We recapitulate briefly: during the night, two officers
    found themselves having stopped four individuals in a car that the
    officers had some reason to believe might be stolen.        The officers
    then discovered that the driver had a firearm concealed in his
    waistband.    Objectively, this situation gives rise to a reasonable
    concern for officer safety -- the officers were outnumbered, in
    relative darkness, and could reasonably believe that they were
    -21-
    dealing with the volatile situation of a possible car theft.                     See
    
    Wilson, 519 U.S. at 414
    ("It would seem that the possibility of a
    violent encounter stems not from the ordinary reaction of a
    motorist stopped for a speeding violation, but from the fact that
    evidence of a more serious crime might be uncovered during the
    stop.     And the motivation of a passenger to employ violence to
    prevent apprehension of such a crime is every bit as great as that
    of the driver."); see also United States v. Brake, 
    666 F.3d 800
    ,
    805-06 (1st Cir. 2011) ("We emphasize once again the importance of
    police officer safety during a Terry stop . . . .").
    Certainly, facts like the late hour (11:00 p.m.) and
    number of passengers in the car (four), when each is taken alone,
    create    no    suspicion   of   criminal    activity.     But     a    number    of
    innocuous facts viewed together may form the basis of reasonable
    suspicion.       See United States v. Wright, 
    582 F.3d 199
    , 212 (1st
    Cir. 2009); 
    Ruidíaz, 529 F.3d at 30
    .                And although Morales's
    inability to provide the officers with a driver's license and a
    legible    car    registration    could     admit   of   several       potentially
    innocent explanations, these facts might also reasonably give rise
    to a suspicion of criminal activity.            See 
    Terry, 392 U.S. at 27
    (permitting police officers to draw "reasonable inferences" based
    on their experience); Arnott, 
    2014 WL 2959288
    , at *3 (stating that
    "reasonable suspicion . . . deals with degrees of likelihood, not
    with certainties or near certainties," and allows "police officers
    -22-
    to    draw    upon   their     experience    and    arrive     at    inferences    and
    deductions").
    Finally,      although     the      discovery        of    a   driver's
    dangerousness may not, in every case, create reasonable suspicion
    that a passenger has a gun, it would be beyond folly for our court
    to ask police officers to ignore the clear relevance of discovering
    a    hidden    firearm    on    the    driver.       Moreover,       in   this   case,
    consideration of that discovery in no way offends the rule of
    Ybarra.       Compare Wyoming v. Houghton, 
    526 U.S. 295
    , 304-05 (1999)
    ("[A] car passenger -- unlike the unwitting tavern patron in Ybarra
    -- will often be engaged in a common enterprise with the driver,
    and have the same interest in concealing the fruits or the evidence
    of their wrongdoing."), with 
    Ybarra, 444 U.S. at 93
    (finding, when
    police    officers     knew     nothing    about    the   defendant       beyond   his
    presence in a tavern where the bartender was suspected of selling
    heroin, that the officers lacked any particular reason to suspect
    that he was armed and dangerous, as required to justify a frisk).
    Reasonable suspicion is ultimately a pragmatic inquiry --
    one that "must be based on commonsense judgments and inferences
    about human behavior."            Illinois v. Wardlow, 
    528 U.S. 119
    , 125
    (2000).      Assessing the totality of the circumstances in this case,
    the    officers'     decision     to    pat-frisk    Tiru    was     grounded     in   a
    reasonable suspicion that he might be armed and dangerous.                         The
    circumstances of the stop, and the facts discovered during its
    -23-
    progression, sufficed to provide a "specific and articulable" basis
    for the decision to pat-frisk Tiru in order to ensure that he did
    not pose a direct threat.        See, e.g., United States v. Espinoza,
    
    490 F.3d 41
    , 47 (1st Cir. 2007) (stating that the "particularity
    requirement" underlying our test for reasonableness requires that
    a   search   be   "'grounded    in   specific    and    articulable   facts.'"
    (quoting United States v. Hensley, 
    469 U.S. 221
    , 229 (1985)).
    The pat-frisk surely represented a "serious intrusion"
    upon Tiru's privacy.     See 
    Terry, 392 U.S. at 17
    .         It was limited in
    scope, however, only to the "bare minimum needed to detect the
    presence of a firearm" -- Officer Martínez began the pat-frisk at
    Tiru's waist and, upon feeling a hard object, extracted it with two
    fingers.     See United States v. Romain, 
    393 F.3d 63
    , 72 (1st Cir.
    2004) (finding a frisk "reasonable under the circumstances and,
    thus,   constitutionally       appropriate,"     when    "the   police   had   a
    plausible basis for suspecting that the appellant was armed and
    dangerous," and the subsequent frisk "began at the appellant's
    waist" and was not more invasive than necessary to determine
    whether the defendant had a gun).               In light of the important
    interest in officer safety, and the facts buttressing the officers'
    belief that Tiru might pose a danger, we find that this significant
    but brief intrusion was supported by reasonable suspicion.                 See
    
    Sowers, 136 F.3d at 27
    (requiring a balance between the "quality of
    -24-
    the intrusion" and the "importance of the governmental interests
    alleged" (quoting 
    Hensley, 469 U.S. at 228
    )).
    III.   Conclusion
    The totality of the circumstances in this case indicate
    that the officers had reasonable suspicion to pat-frisk Tiru.   We
    therefore affirm the district court's denial of Tiru's motion to
    suppress the firearm.
