OPINION
This is an appeal by the United States from a pre-trial order suppressing evidence in a criminal prosecution. Specifically, the Government seeks to reverse the district court’s suppression of a firearm that was found in the possession of passenger-defendant Gary Moorefield after the car in which he was riding was stopped for a routine traffic violation.
Moorefield argues that the pistol must be suppressed for two reasons. First, he submits that the police officers involved in the traffic stop unlawfully ordered him and the driver to remain in the car with their hands in the air. Second, he contends that the pat-down that produced the weapon was illegal.
We hold that police officers may constitutionally order occupants of cars to remain in the vehicle with their hands up in the air. We further hold that based on Moorefield’s behavior, and in particular his failure to follow directions, the officers were justified in conducting a pat-down for weapons.
I.
Moorefield was charged in one count of a five-count indictment with possession of a firearm by a convicted felon in violation of 18 U.S.C. § 922(g)(l)(Supp.1997). He originally pled not guilty but later changed his plea to guilty. Subsequently, however, he withdrew his plea of guilty and filed a motion to suppress the pistol that was found on his person when he was frisked following a routine traffic stop. The district court held an evidentia-ry hearing at which Police Officer Anthony Wiles was the sole witness for the government. Officer Wiles’ account of the facts is essentially undisputed.
At approximately 10:13 p.m. on July 28, 1994, Officer Wiles and his partner were on routine patrol in the East Liberty section of Pittsburgh. At that time they observed a car make a right turn, cross from the right lane into the left lane in front of traffic, almost hit an oncoming ear, and then make a left turn without signaling. Because of the violation of the Pennsylvania Motor Vehicle Code, 75 Pa.C.S.A. § 3334 (West 1996), but not by reason of any suspicion that the occupants of the car were engaged in criminal activity, the officers required the vehicle to stop and pull over to the side of the road.
The car had two occupants, driver Dana Moore and passenger Moorefield. After Moore pulled the car over, Moorefield attempted to exit the car. The officers instructed him to remain in the vehicle. For their personal safety and as a routine practice, the officers instructed both Moore and *12 Moorefield to show their hands at all times or to put their hands up in the air. Moore followed the officers’ directions. Moorefield did not.
Wiles perceived Moorefield to lean back and shove something down toward his waist. Once again, the officers directed him to show his hands. In response, Moorefield pushed his upper-body out of the window, which again prompted the officers to order him to remain inside the car with his hands in view. He then raised and lowered his hands several times before finally keeping them up in the air as instructed. Officer Wiles testified that because of Moorefield’s suspicious hand and body movements, he believed that Moorefield may have been trying to conceal a weapon or narcotics.
The officers requested additional police assistance. When the back-up unit arrived, they approached the vehicle and ordered Moore and Moorefield to step out. Moore-field exited the car with his hands up. At that time and for safety reasons, Officer Wiles conducted a pat-down search for weapons. The pat-down revealed a pistol in the waistband of Moorefield’s shorts. Moorefield filed a motion to suppress the pistol from being received into evidence.
Following an evidentiary hearing and relying on
Pennsylvania v. Mimms,
II.
For Fourth Amendment purposes, the traffic stop in this matter may be divided into four stages: (1) the initial stop, (2) the order to remain in the vehicle with hands in view, (3) the order to exit the car, and (4) the pat-down search for weapons.
With respect to the first stage, Moorefield does not contest the legality of the initial stop of the vehicle. It is well-established that a traffic stop is lawful under the Fourth Amendment where a police officer observes a violation of the state traffic regulations.
See, e.g., Mimms,
A.
We turn first to whether the police officers lawfully ordered passenger Moore-field to remain in the car and put his hands in the air while the traffic stop was being conducted. We adjudicate this issue in light of the recent Supreme Court ease of
Maryland v. Wilson,
— U.S. -,
In arriving at this conclusion, the Court balanced under the Fourth Amendment the public interest in officer safety against the passenger’s right to “personal security free from arbitrary interference by law [enforcement] officers.”

In view of the Supreme Court’s ruling in Wilson, we have no hesitancy in holding that the officers lawfully ordered Moorefield to remain in the car with his hands in the air. We follow the Court’s analysis in Wilson. The only change in Moorefield’s circumstances resulting from the order to remain in the car and put his hands in the air, was that he remained inside of the stopped car with his hands in view, rather than inside of the stopped ear with his hands lowered into a passenger compartment that could potentially contain a concealed weapon. Just as the Court in Wilson found ordering a passenger out of the car to be a minimal intrusion on personal liberty, we find the imposition of having to remain in the car with raised hands equally minimal. We conclude that the benefit of added officer protection far outweighs this minor intrusion.
B.
The second issue that we must'review is whether the officers lawfully conducted a pat-down for weapons. The Supreme Court has repeatedly recognized that traffic stops are dangerous encounters that result in assaults and murders of police officers.
See, e.g., Wilson,
— U.S. at - - -,
In
Terry v. Ohio,
Utilizing the standards set forth by the Supreme Court in cases such as
Terry, Long,
and
Mimms,
many courts of appeals have upheld limited weapon pat-downs of passengers where the passengers have engaged in suspicious behavior similar to that of Moore-field. For example, in
United States v. Fryer,
Similarly in this case, Officer Wiles pointed to “specific and articulable facts which, taken together with rational inferences from those facts,” reasonably warranted the pat-down.
See Terry,
We find that the district court erred in concluding the patdown unjustified. Officer Wiles’ pat-down search of Moorefield was reasonable under the Fourth Amendment, and the pistol seized pursuant to the search may properly be introduced into evidence. We will reverse the September 5,1996, order of the district court suppressing the firearm seized from Moorefield, and remand for further proceedings.
