                                        State of Nebraska,        appellee, v.
                                         Ryan M. Barbeau,       appellant.
                                                    ___ N.W.2d ___

                                        Filed October 12, 2018.   No. S-17-1158.

                1.	 Constitutional Law: Search and Seizure: Motions to Suppress:
                    Appeal and Error. When reviewing a trial court’s ruling on a motion
                    to suppress based on a claimed violation of the Fourth Amendment, an
                    appellate court applies a two-part standard of review. Regarding histori-
                    cal facts, an appellate court reviews the trial court’s findings for clear
                    error, but whether those facts trigger or violate Fourth Amendment
                    protections is a question of law that an appellate court reviews indepen-
                    dently of the trial court’s determination.
                2.	 Investigative Stops: Appeal and Error. The ultimate determinations
                    of reasonable suspicion to conduct an investigatory stop are reviewed
                    de novo, and findings of fact are reviewed for clear error, giving due
                    weight to the inferences drawn from those facts by the trial judge.
                3.	 Constitutional Law: Search and Seizure. Both the Fourth Amendment
                    to the U.S. Constitution and article I, § 7, of the Nebraska Constitution
                    guarantee the right of the people to be secure in their persons, houses,
                    papers, and effects against unreasonable searches and seizures.
                4.	 Constitutional Law: Search and Seizure: Investigative Stops: Motor
                    Vehicles. A traffic stop is a seizure for Fourth Amendment purposes, and
                    therefore is accorded Fourth Amendment protections.
                5.	 Investigative Stops: Motor Vehicles: Police Officers and Sheriffs:
                    Probable Cause. As a general matter, the decision to stop an automo-
                    bile is reasonable where the police have probable cause to believe that a
                    traffic violation has occurred. A traffic violation, no matter how minor,
                    creates probable cause to stop the driver of a vehicle.
                6.	 Constitutional Law: Investigative Stops: Motor Vehicles: Police
                    Officers and Sheriffs: Probable Cause. Probable cause is not the only
                    standard applied by courts to determine whether a traffic stop is reason-
                    able under the Fourth Amendment. The Fourth Amendment also permits
                    brief investigative stops of vehicles based on reasonable suspicion when

     a law enforcement officer has a particularized and objective basis for
     suspecting the particular person stopped of criminal activity.
 7.	 Probable Cause. Like the probable cause standard, the reasonable sus-
     picion standard takes into account the totality of the circumstances.
 8.	 Constitutional Law: Investigative Stops: Police Officers and
     Sheriffs: Probable Cause. Police can constitutionally stop and briefly
     detain a person for investigative purposes if the police have a reasonable
     suspicion, supported by articulable facts, that criminal activity exists,
     even if probable cause is lacking under the Fourth Amendment.
 9.	 Probable Cause: Words and Phrases. Reasonable suspicion entails
     some minimal level of objective justification for detention, something
     more than an inchoate and unparticularized suspicion or hunch, but less
     than the level of suspicion required for probable cause.
10.	 Judgments: Records: Appeal and Error. Where the record adequately
     demonstrates that the decision of a trial court is correct—although such
     correctness is based on a ground or reason different from that assigned
     by the trial court—an appellate court will affirm.
11.	 Constitutional Law: Investigative Stops: Motor Vehicles: Police
     Officers and Sheriffs: Statutes. Reasonable suspicion, as a prerequi-
     site for a constitutional investigatory stop, cannot be based only on a
     police officer’s desire to verify compliance with motor vehicle registra-
     tion statutes.
12.	 Investigative Stops: Motor Vehicles: Police Officers and Sheriffs:
     Statutes. When an officer observes a vehicle without license plates
     or in-transit tags, a particularized and objective basis exists to justify
     a reasonable, articulable suspicion that the driver may be criminally
     avoiding the motor vehicle registration statutes. The State’s interest
     in enforcing its registration laws supports a brief investigatory stop to
     ascertain whether the driver possesses the necessary documentation to
     show compliance with the motor vehicle registration statutes.
13.	 Probable Cause: Police Officers and Sheriffs. Reasonable suspicion
     can be premised on an officer’s mistake of fact or mistake of law, so
     long as the mistake was reasonable.
14.	 ____: ____. A determination that reasonable suspicion exists need not
     rule out the possibility of innocent conduct. The inquiry is not whether
     some circumstances may be susceptible of innocent explanation, but
     whether, taken together, they suffice to form a particularized and objec-
     tive basis for the officer to suspect a crime is, or is about to, occur.
15.	 Police Officers and Sheriffs: Motor Vehicles: Probable Cause.
     Exiting a highway after passing a sign indicating there is a police
     checkpoint ahead does not, without more, give rise to reasonable suspi-
     cion. But it is one factor which can be considered in the totality of the
     circumstances.

16.	 Investigative Stops: Motor Vehicles: Time. A lawful traffic stop can
     become unlawful if it is prolonged beyond the time reasonably required
     to complete the mission of the stop.
17.	 Investigative Stops: Motor Vehicles: Police Officers and Sheriffs.
     Once a vehicle is lawfully stopped, a law enforcement officer may con-
     duct an investigation reasonably related in scope to the circumstances
     that justified the traffic stop. This investigation may include asking
     the driver for an operator’s license and registration, requesting that
     the driver sit in the patrol car, and asking the driver about the purpose
     and destination of his or her travel. Also, the officer may run a com-
     puter check to determine whether the vehicle involved in the stop has
     been stolen and whether there are any outstanding warrants for any of
     its occupants.

  Appeal from the District Court for Hamilton County: R achel
A. Daugherty, Judge. Affirmed.
   Mark Porto, of Porto Law Office, for appellant.
  Douglas J. Peterson, Attorney General, and Joe Meyer for
appellee.

Papik, and Freudenberg, JJ.
   Stacy, J.
   Ryan M. Barbeau appeals his convictions for drug-related
felonies, arguing the evidence was obtained as the result of an
unconstitutional traffic stop and should have been suppressed.
The district court overruled his motion to suppress, finding the
traffic stop was supported by probable cause. We do not reach
the question of probable cause, because we conclude this was
an investigatory traffic stop supported by reasonable suspicion.
Therefore, although our reasoning differs from that of the dis-
trict court, we agree the motion to suppress was properly over-
ruled, and we therefore affirm.
                    BACKGROUND
  On December 11, 2015, Nebraska State Patrol Trooper
Gregory Goltz was conducting a “ruse checkpoint” operation
                              - 296 -

at the Giltner interchange on Interstate 80 in Hamilton County,
Nebraska. As part of that operation, signs were placed along
the Interstate advising drivers there was a State Patrol check-
point ahead and a drug dog in use. No such Interstate check-
point actually existed, but troopers monitored vehicles that left
the Interstate immediately after passing the sign.
   At approximately 2:52 p.m., Goltz saw a Lincoln Town Car
leave the Interstate after passing the checkpoint sign. The car
stopped at the end of the off ramp, signaled, and turned north
onto the Giltner spur. Goltz followed the car, eventually catch-
ing up to it and traveling several car lengths behind it. The car
was not speeding.
   Goltz could see the car had no license plates, but had what
appeared to be an in-transit tag mounted inside a black license
plate holder on the rear of the car. Portions of the in-transit
tag were covered by the top and bottom of the frame, prevent-
ing Goltz from reading the state of issuance and some of the
numbers and handwriting on the tag. Goltz also noticed some
of the handwritten numbers on the in-transit tag were written in
red ink; he considered that unusual because he had never seen
a Nebraska in-transit tag with red ink before. Goltz initiated a
traffic stop.
   After the car was stopped, Goltz approached it on foot and
was able to read “North Carolina” on the in-transit tag. There
were two individuals in the car. Goltz made contact with the
driver and explained he had been stopped because his car did
not have plates and the trooper could not read the in-transit
tag. Goltz asked to see an operator’s license and identified the
driver as Barbeau.
   Goltz asked to see the car’s paperwork to determine whether
the in-transit tag was “real.” Barbeau told Goltz he had recently
purchased the car in North Carolina and was driving it back to
his home in Oregon. But Barbeau was not able to produce any
paperwork or insurance information on the car.
   When Barbeau was unable to produce any paperwork for
the car, Goltz had him step out of the car and walk to the

front of Goltz’ patrol car. Goltz’ plan was to “investigate the
vehicle” and obtain additional information from Barbeau about
“where the vehicle came from” and Barbeau’s travel plans.
Goltz then got into his patrol car to run Barbeau’s operator’s
license and wait for backup. Goltz had called for backup, and
a canine unit, almost immediately after the stop. According to
Goltz, he planned to return to Barbeau’s car to take a closer
look at the in-transit tag once backup arrived.
   Within a few minutes of the initial stop, another trooper
arrived on the scene and obtained the passenger’s identification
information. When Goltz ran the passenger’s information, he
learned there was an active warrant for his arrest. The passen-
ger was then arrested and handcuffed.
   After the passenger was arrested, the dog alerted to drugs
in the trunk of Barbeau’s car. A subsequent search of the car
yielded an AR-15 semiautomatic rifle with ammunition and
a 30-round clip; two marijuana pipes; 40 tramadol pills; 60
hydrocodone pills; and $39,575, which was determined to have
been used in a controlled substance transaction.
   Barbeau was then arrested and charged with (1) posses-
sion of a controlled substance with intent to deliver while in
possession of a firearm, (2) possession of a deadly weapon
during the commission of a felony, (3) possession of drug
money, and (4) possession of a controlled substance. Goltz
did not issue Barbeau a ticket or a warning related to the
in-transit tag.
   Before trial, Barbeau moved to suppress the evidence
obtained from the search of his car. Barbeau argued Goltz did
not have probable cause or reasonable suspicion to initiate the
traffic stop. Alternatively, he argued the stop should have been
terminated as soon as Goltz could read the information on the
in-transit tag.
   The State countered that Goltz had probable cause for the
traffic stop based on the partially obscured in-transit tag.
The State claimed this was a violation of Neb. Rev. Stat.
§ 60-399(2) (Reissue 2010), which requires that “[a]ll letters,
                                     - 298 -

numbers, printing, writing, and other identification marks” on
plates “shall be kept clear . . . so that they shall be plainly
visible at all times during daylight and under artificial light in
the nighttime.”
   At the evidentiary hearing on the motion to suppress, Goltz
testified to the facts summarized above and a video record-
ing of the stop was received into evidence. The court found
that some of the information on the in-transit tag was covered
by the license plate frame, and because the printing was not
“plainly visible,” the court concluded that Goltz had probable
cause to suspect a violation of § 60-399(2). The court rejected
Barbeau’s claim that the traffic stop should have ended once
Goltz approached the car and could read the in-transit tag was
from North Carolina. The court reasoned that once the car was
lawfully stopped, Nebraska law permitted Goltz to conduct an
investigation reasonably related in scope to the circumstance
that justified the traffic stop, including asking the driver for
an operator’s license and registration, requesting the driver to
sit in the patrol car, asking the driver about the purpose and
destination of his or her travel, and running a computer check
to determine whether the vehicle involved in the stop had been
stolen and whether there were outstanding warrants for any
of its occupants.1 The trial court reasoned that while troopers
were conducting such an investigation, they discovered the
passenger had an active warrant. They then arrested the pas-
senger and conducted a postarrest search, during which the
drugs, gun, and money were discovered. The trial court over-
ruled the motion to suppress.
   The State and Barbeau subsequently entered into an agree-
ment whereby the State would drop the charge of posses-
sion of a deadly weapon during the commission of a felony
in exchange for a bench trial on stipulated facts. At the
bench trial, Barbeau renewed his motion to suppress evidence
obtained from the stop.

   The trial court found Barbeau guilty of possession of a
controlled substance with intent to deliver, possession of drug
money, and possession of a controlled substance. Barbeau was
sentenced to concurrent terms of imprisonment, the longest
of which was 18 to 36 months. He timely appealed, and we
moved the case to our docket on our own motion.2
                ASSIGNMENTS OF ERROR
   Barbeau assigns, restated, that the district court erred in
(1) denying his motion to suppress and (2) finding him guilty
based on evidence that should have been suppressed.
                   STANDARD OF REVIEW
   [1] When reviewing a trial court’s ruling on a motion to sup-
press based on a claimed violation of the Fourth Amendment,
an appellate court applies a two-part standard of review.3
Regarding historical facts, an appellate court reviews the trial
court’s findings for clear error, but whether those facts trig-
ger or violate Fourth Amendment protections is a question of
law that an appellate court reviews independently of the trial
court’s determination.4
   [2] The ultimate determinations of reasonable suspicion to
conduct an investigatory stop are reviewed de novo, and find-
ings of fact are reviewed for clear error, giving due weight to
the inferences drawn from those facts by the trial judge.5
                          ANALYSIS
   Barbeau contends the traffic stop in this case violated the
Fourth Amendment to the U.S. Constitution and article I, § 7,
of the Nebraska Constitution, both of which protect individuals
against unreasonable searches and seizures by the government.
He argues the traffic stop was not supported by either probable

cause or reasonable suspicion, and he also challenges the dura-
tion of the investigation, arguing that once Goltz approached
the car and was able to read the in-transit tag, no further inves-
tigation was justified.
   Because Barbeau’s motion to suppress focused only on
the lawfulness and duration of the traffic stop, and did not
challenge whether the search of his car was supported by
probable cause, we confine our analysis accordingly. We
begin by setting out the constitutional principles governing
traffic stops.
              Traffic Stops Must Be Supported by
                     Either Probable Cause or
                       R easonable Suspicion
   [3,4] The Fourth Amendment guarantees “[t]he right of
the people to be secure in their persons, houses, papers, and
effects, against unreasonable searches and seizures . . . ,” as
does article I, § 7, of the Nebraska Constitution. A traffic stop
is a seizure for Fourth Amendment purposes, and therefore is
accorded Fourth Amendment protections.6
   [5] As a general matter, the decision to stop an automobile is
reasonable where the police have probable cause to believe that
a traffic violation has occurred.7 We have long recognized that
a traffic violation, no matter how minor, creates probable cause
to stop the driver of a vehicle.8
   [6,7] But probable cause is not the only standard applied
by courts to determine whether a traffic stop is reasonable
under the Fourth Amendment. The U.S. Supreme Court has

recognized the Fourth Amendment permits brief investiga-
tive stops of vehicles based on reasonable suspicion when a
law enforcement officer has a “‘particularized and objective
basis for suspecting the particular person stopped of crimi-
nal activity.’”9 The reasonable suspicion needed to justify an
investigatory traffic stop “‘is dependent upon both the con-
tent of information possessed by police and its degree of
reliability.’”10 Like the probable cause standard, the reasonable
suspicion standard “takes into account ‘the totality of the cir-
cumstances—the whole picture.’”11 A mere hunch does not cre-
ate reasonable suspicion, but the level of suspicion required to
meet the standard is “‘considerably less than proof of wrong-
doing by a preponderance of the evidence,’ and ‘obviously less’
than is necessary for probable cause.”12
   [8,9] Nebraska courts have also applied the reasonable sus-
picion standard when considering the lawfulness of a traffic
stop.13 In doing so, this court has recognized that “‘[p]olice can
constitutionally stop and briefly detain a person for investiga-
tive purposes if the police have a reasonable suspicion, sup-
ported by articulable facts, that criminal activity exists, even if
probable cause is lacking under the [F]ourth [A]mendment.’”14

We have explained that “‘[r]easonable suspicion entails some
minimal level of objective justification for detention, some-
thing more than an inchoate and unparticularized suspicion or
“hunch,” but less than the level of suspicion required for prob-
able cause.’”15 When determining whether there is reasonable
suspicion for a police officer to make an investigatory stop, the
totality of the circumstances must be taken into account.16
                  Traffic Stop Was Supported
                    by R easonable Suspicion
   [10] Before analyzing whether there was reasonable suspi-
cion to support this traffic stop, we pause briefly to address
Barbeau’s arguments focused on the district court’s finding
of probable cause. The district court found the initial traffic
stop was supported by probable cause to believe a violation
of § 60-399(2) had occurred, because some of the printing on
the in-transit tag was not “plainly visible.” Barbeau argues,
on appeal, that he was not a resident of Nebraska and thus
was only required to comply with the registration require-
ments of Neb. Rev. Stat. § 60-367 (Cum. Supp. 2016). Section
60-367 provides that nonresident vehicles must comply with
the registration requirements of the owner’s state of residence
and “conspicuously” display registration numbers as required
thereby. Barbeau argues that because he was not required to
comply with the “plainly visible” requirement of § 60-399(2),
there could be no probable cause to suspect a violation of
that statute. Because we find the stop was investigatory in
nature and was supported by reasonable suspicion, we do not
address the district court’s probable cause finding, and we
express no opinion on whether the “plainly visible” require-
ment of § 60-399(2) applies to nonresidents. Where the record
adequately demonstrates that the decision of a trial court is cor-
rect—although such correctness is based on a ground or reason

different from that assigned by the trial court—an appellate
court will affirm.17
   When considering whether there was reasonable suspicion to
support the traffic stop in this case, our prior decisions in State
v. Childs18 and State v. Bowers19 are instructive. Both cases
involved investigatory traffic stops based on suspected vehicle
registration violations.
   [11] In Childs, police observed a car driving with in-transit
tags and stopped the car to check whether the tags were still
within the valid timeframe for use. On those facts, we con-
cluded there was no reasonable suspicion for the stop, and we
rejected the State’s contention that whenever police see a vehi-
cle operating on the street with an in-transit tag, they should
suspect a violation of the motor vehicle registration laws. We
found it significant that before stopping the vehicle, police
noticed “nothing suspicious or out of the ordinary” about the
operation of the vehicle, the appearance of the vehicle, or the
appearance of the in-transit tag.20 We held that “[r]easonable
suspicion, as a prerequisite for a constitutional investigatory
stop, cannot be based only on a police officer’s desire to verify
compliance with motor vehicle registration statutes.”21 Because
police had no articulable facts upon which to suspect the driver
“had been engaged in, was presently engaged in, or was about
to engage in any criminal activity,”22 we found the traffic stop
was unconstitutional.
   [12] Three years after Childs, we decided Bowers. In that
case, we found police had reasonable suspicion to conduct
an investigatory traffic stop of a car being operated without

license plates or in-transit tags. The driver in Bowers argued
the absence of plates or in-transit tags did not provide reason-
able suspicion to believe he was operating the car unlawfully.
He reasoned that under Neb. Rev. Stat. § 60-320.01 (Reissue
1993), he could lawfully operate the car without plates or an
in-transit tag for 30 days after purchase from a nonlicensed
seller, provided he could produce the proper documentation of
ownership upon demand. We agreed that the driver was in “full
compliance with the motor vehicle licensing laws,” but we
observed that “[s]ome people who operate motor vehicles with-
out license plates or in-transit tags clearly do so in an unlawful
attempt to escape the requirements of the motor vehicle regis-
tration statutes.”23 We reasoned:
         When an officer observes a vehicle without license
      plates or in-transit tags, a particularized and objective
      basis exists to justify a reasonable, articulable suspi-
      cion that the driver may be criminally avoiding the
      motor vehicle registration statutes. The State’s inter-
      est in enforcing its registration laws supports a brief
      investigatory stop to ascertain whether the driver pos-
      sesses the necessary documentation to establish that he
      or she is within the 30-day grace period to register the
      vehicle.24
   The Nebraska Court of Appeals applied similar reasoning
in State v. Kling 25 and found police had reasonable suspi-
cion to conduct an investigatory stop of a vehicle displaying
handwritten in-transit tags. The driver in Kling argued that
handwritten in-transit tags did not violate state law, and he
relied on Childs for the proposition that an officer’s desire
to merely verify compliance with registration laws does not,
without more, amount to reasonable suspicion. The State
countered that handwritten in-transit tags should have the

same legal effect as no in-transit tags, and thus relied on
Bowers for the proposition that when a car is being operated
without displaying plates or in-transit tags, police have a par-
ticularized and objective basis to suspect the vehicle registra-
tion laws are being violated.
   The Court of Appeals reviewed our holdings in Childs and
Bowers and concluded the facts presented in Kling were more
akin to Bowers. That court observed that although Nebraska
law did not prohibit handwritten in-transit tags, neither did it
authorize them. Thus, the court held that when police saw the
car being operated without plates or dealer-issued in-transit
tags, that observation provided reasonable suspicion the driver
was violating the motor vehicle registration laws and justified
the investigatory stop.
   [13,14] These cases illustrate that the determination of rea-
sonable suspicion is fact specific and requires police to have
a particularized and objective basis for suspecting a driver is
violating the vehicle registration law. Childs teaches that an
officer’s desire to verify whether an in-transit tag is valid will
not, without more, be sufficient to provide reasonable suspi-
cion the vehicle is being operated in violation of the vehicle
registration laws. But Bowers and Kling illustrate that when
police have reliable information that provides a particularized
and objective basis for suspecting the vehicle is being operated
in violation of the vehicle registration laws, there is reason-
able suspicion to conduct an investigatory traffic stop. This
is so even if the reasonable suspicion is premised on an offi-
cer’s mistake of fact or mistake of law, so long as the mistake
was reasonable.26 Moreover, a determination that reasonable
suspicion exists need not rule out the possibility of innocent
conduct.27 The inquiry is not whether some circumstances may
be susceptible of innocent explanation, but whether, taken

together, they suffice to form a particularized and objective
basis for the officer to suspect a crime is occurring, or is about
to occur.28
   The question of reasonable suspicion in this case, then, turns
on whether, considering the totality of the circumstances, Goltz
had reliable information that provided a particularized and
objective basis for suspecting Barbeau was operating his car in
violation of the motor vehicle registration laws.
   Barbeau does not challenge the district court’s factual find-
ings concerning Goltz’ information and observations, and we
find no clear error in those findings. Applying the constitu-
tional principles discussed above to those factual findings,
we conclude Goltz had an objective basis, based on firsthand
observation, for reasonably suspecting Barbeau was operating
his car in violation of the registration laws.
   First, as in Bowers, there were objective signs of pos-
sible noncompliance with Nebraska’s registration laws. Under
Nebraska law, a dealer-issued in-transit “sticker shall [have]
plainly printed in black letters the words In Transit” and
must be displayed either on the front and rear windows or on
the rear side windows of the vehicle.29 The in-transit tag on
Barbeau’s car was located on the rear bumper and included red
handwriting. Goltz had never seen a Nebraska in-transit tag
with red handwriting. Moreover, the tag was affixed inside a
license plate frame that partially obstructed the information on
the top and bottom of the tag, preventing Goltz from being able
to read the state of issuance.
   Unlike the police in Childs, Goltz did not initiate a traffic
stop merely to check the validity of the tags without any rea-
sonable suspicion they were noncompliant. Nor does the record
support the conclusion that Goltz initiated the traffic stop based
on nothing more than his inability to read the in-transit tag

while pursuing the car.30 Rather, in addition to the inability of
Goltz to read some of the information on the tag, the tag itself
appeared suspect due to its location on the car, the red ink,
and the fact that some information was covered by the license
plate frame.
   [15] Moreover, when considering the totality of the circum-
stances, we also consider that Goltz had seen Barbeau exit the
Interstate immediately after passing a sign advising drivers
there was a State Patrol checkpoint ahead. Exiting a highway
after passing a sign indicating there is a police checkpoint
ahead does not, without more, give rise to reasonable suspi-
cion.31 It is, however, “one factor which can be considered in
the totality of the circumstances.”32 And here, Goltz’ knowl-
edge that Barbeau pulled off the Interstate immediately after
passing a sign notifying drivers of an upcoming State Patrol
checkpoint, when combined with the irregular appearance of
the temporary tag and the fact that some information on the
tag was covered by the frame, creates a particularized and
objectively reasonable suspicion that the vehicle is not in com-
pliance with the registration laws and that the driver wants to
evade detection.
   We therefore determine the investigatory stop of Barbeau’s
car was supported by reasonable suspicion and comported with
the Fourth Amendment to the U.S. Constitution and article I,
§ 7, of the Nebraska Constitution.

  Barbeau contends that even if the initial stop was lawful,
Goltz should have ended the stop as soon as he approached

the car and was able to see the in-transit tag was from North
Carolina. According to Barbeau, any continued investigation
beyond that point was unreasonable, and thus unlawful.
   [16] In Rodriguez v. U.S.,33 the U.S. Supreme Court cau-
tioned that a lawful traffic stop “‘can become unlawful if it
is prolonged beyond the time reasonably required to com-
plete th[e] mission’” of the stop. When the mission of an
investigative stop is addressing a suspected traffic violation,
the stop may “‘last no longer than is necessary to effectu-
ate th[at] purpose’” and authority for the seizure “thus ends
when tasks tied to the traffic infraction are—or reasonably
should have been—completed.”34 However, the U.S. Supreme
Court has recognized that beyond just determining whether
to issue a traffic citation or warning, an officer’s mission in a
traffic stop “includes ‘ordinary inquiries incident to [the traf-
fic] stop.’”35 Typically, “such inquiries involve checking the
driver’s license, determining whether there are outstanding
warrants against the driver, and inspecting the automobile’s
registration and proof of insurance.”36
   [17] Similarly, this court has long held that once a vehicle
is lawfully stopped, a law enforcement officer may conduct
an investigation reasonably related in scope to the circum-
stances that justified the traffic stop.37 This investigation may
include asking the driver for an operator’s license and reg-
istration, requesting that the driver sit in the patrol car, and
asking the driver about the purpose and destination of his or
her travel.38 Also, the officer may run a computer check to
determine whether the vehicle involved in the stop has been

stolen and whether there are any outstanding warrants for any
of its occupants.39
   Having concluded the investigatory stop of Barbeau’s car
was lawful, we agree with the trial court that Goltz was justi-
fied in conducting an investigation related to the circumstances
that justified the stop and gave rise to Goltz’ reasonable suspi-
cion that the car was being operated in violation of the motor
vehicle registration laws. The record shows that after initiat-
ing the stop, Goltz approached the car, briefly inspected the
in-transit tag, and then proceeded to contact the driver and
ask many of the routine questions that this court, and the U.S.
Supreme Court, have recognized as appropriate incidental to a
traffic stop.
   On appeal, Barbeau does not claim the scope of Goltz’
investigation was too broad under the circumstances, nor does
he argue the few minutes it took for backup and the canine unit
to arrive unnecessarily extended the stop. Instead, he argues
the entire investigation should have ended before Goltz made
contact with the driver.
   Barbeau’s argument in this regard is premised on the flawed
assumption that the only justification for the stop was Goltz’
inability to read the state of issuance on the in-transit tag.
Summarized, Barbeau argues that he was stopped because
Goltz could not see the state of issuance on the in-transit tag,
so he argues that once Goltz approached the car and was able
to read “North Carolina,” the purpose of the traffic stop was
accomplished and no further investigation was warranted.
   But as discussed above, the circumstances justifying the
investigatory stop here included more than just Goltz’ inability
to read the state of issuance on the in-transit tag. In addition
to being unable to read some of the information on the tag,
the tag itself appeared suspect due to its location, the red ink,
and the fact that it was partially covered by the license plate
frame. The additional fact that Barbeau was seen exiting the

Interstate immediately after passing a sign notifying drivers
of an upcoming State Patrol checkpoint, combined with the
irregular appearance of the temporary tag, gave Goltz a partic-
ularized and objectively reasonable suspicion that the car was
not in compliance with the registration laws and that the driver
wanted to evade detection. Having lawfully stopped the car,
Goltz was authorized to conduct an investigation reasonably
related in scope to the circumstances that justified the traffic
stop,40 and the record supports that he did just that.
   There is no merit to Barbeau’s claim that the investigatory
stop should have ended before Goltz contacted the driver to
begin his investigation.
                        CONCLUSION
   For the reasons discussed above, the district court did not
err in overruling the motion to suppress. Barbeau’s assign-
ments of error have no merit, and we therefore affirm the judg-
ment of the district court.
