After a Greeley, Colorado police officer discovered a sawed-off shotgun in Defendant’s vehicle during a traffic stop, a grand jury indicted Defendant on one count of possession of an unregistered sawed-off shotgun in violation of 26 U.S.C. § 5861. Defendant moved to suppress the shotgun. According to Defendant, the officer did not have reasonable suspicion to stop his vehicle, or, in the alternative, the officer unreasonably prolonged the traffic stop by asking him questions outside the scope of the traffic violation. The district court concluded the officer acted reasonably throughout the course of the stop and denied Defendant’s motion to suppress. Defendant subsequently entered a conditional guilty plea, reserving the right to appeal the district court’s order.
See
Fed. R.Crim.P. 11(a)(2). Defendant now appeals. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review the district court’s reasonableness determination de novo,
see United States v. Rice,
I.
The parties stipulated to the all of the following facts: On October 8, 2005, at approximately 11:59 p.m., Detective Shad Baxter of the Greeley, Colorado Police Department observed a Lincoln Town Car traveling westbound in the left through lane, directly ahead of his patrol car. Baxter watched as the Lincoln crossed the white painted lane divider into the right westbound through lane. The Lincoln drifted approximately three to four feet into the right lane, and continued in this manner for several seconds before pulling back into the left lane. The driver of the Lincoln displayed no signal before crossing into the right lane or back into the left lane.
Detective Baxter activated his emergency lights. Defendant pulled over and stopped the Lincoln next to the curb. Detective Baxter walked to the driver’s side window. Inside the vehicle he saw four young males. Detective Baxter told Defendant why he had stopped him, and asked him for his driver’s license, registration, and proof of insurance. Defendant *888 informed Detective Baxter he did not have his driver’s license with him but identified himself by name. Defendant then handed Detective Baxter a plastic sleeve with registration and insurance information for the Lincoln.
Detective Baxter asked Defendant whether he would be willing to get out of the car and speak with him. Defendant agreed, got out of the car, and walked with Baxter to the rear of the Lincoln. Very shortly into their conversation, Detective Baxter asked Defendant whether he or any of the others in the car had any type of weapons or illegal items. Defendant answered by saying “not that I know of,” or words to that effect. Detective Baxter then asked whether it would be “O.K.” to search the vehicle for weapons or any other illegal items. Defendant answered this question by telling the detective a shotgun was in the back seat area. Detective Baxter promptly handcuffed Defendant and placed him in the backseat of another officer’s patrol car which had recently arrived as backup. To ensure everyone’s safety, the detective removed the remaining occupants from the car and handcuffed them as well.
Detective Baxter then looked into the Lincoln through the rear window of the driver’s side. On the floorboard behind the driver’s seat, the detective could see the butt stock of a sawed-off shotgun, which was partially wrapped in a white t-shirt. The firearm was situated so that the barrel-end of the shotgun was pointing toward the front of the car, under the driver’s seat. Detective Baxter retrieved the shotgun and the indictment followed.
II.
A traffic stop is a seizure for Fourth Amendment purposes, the propriety of which we measure under the standards set forth in
Terry v. Ohio,
A.
Defendant first argues Detective Baxter did not have reasonable suspicion to stop his vehicle. As noted above, Detective Baxter stopped Defendant’s car because Defendant, without signaling, crossed three or four feet into the right westbound lane and stayed in that position for several seconds before crossing back into the left westbound lane. Detective Baxter be *889 lieved Defendant’s actions violated Colo. Rev.Stat. § 42—4—1007(l)(a), which provides “[a] vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety.”
Relying on
United States v. Gregory,
Defendant asserts this case falls “squarely within the bounds of
Gregory.”
We disagree. Several facts distinguish this case from
Gregory.
First, in
Gregory,
the defendant was traveling in a moving truck where the road was winding, the terrain was mountainous and the weather condition was windy.
Gregory,
Additionally, the movement of the vehicle in
Gregory
occurred toward the right shoulder of the road, so other traffic was in no danger of collision. In this case, Defendant moved his vehicle three to four feet into another lane of traffic, essentially straddling the lane divider for several seconds. This movement is more significant than the brief two-feet lane drift under windy conditions described in
Gregory. See Gregory,
B.
Defendant also argues Detective Baxter’s questioning regarding the presence of weapons “or other illegal items” and his request to search Defendant’s vehicle unreasonably extended the detention in violation of his Fourth Amendment rights. We begin our analysis of Defendant’s alternative argument with Detective
*890
Baxter’s first question: “Do you have any weapons or other illegal items in your vehicle?” For several years the rule in this circuit has been police officers are free to question individuals regarding the presence of weapons.
See United States v. Holt,
Recent precedent informs us that the second portion of Detective Baxter’s first question,
ie.,
whether “other illegal items” were in the car, was also permissible. In
Alcaraz-Arellano,
we ruled that officers may ask questions outside the scope of the traffic stop so long as the questions do not appreciably prolong the length of the stop.
See Alcaraz-Arellano,
We do not believe our precedent requires such a narrow approach. Our cases do not focus on the order of events. Rather, our cases focus on the reasonableness of the traffic stop in light of both the length of the detention and the manner in which it was carried out. See id. at 1258. In this case, Detective Baxter’s question regarding the presence of other “illegal items” did not appreciably lengthen the duration of the stop. The officer’s inquiry required a simple yes or no answer and could not have taken more than two or three seconds to ask. That Detective Baxter did not ask the question while actively processing Defendant’s traffic infraction does not render Defendant’s momentary detention unreasonable.
Detective Baxter’s second question, “may I search,” also did not violate Defendant’s Fourth Amendment rights. Again, the key inquiry is whether Defendant’s detention was reasonable.
Patterson,
We have repeatedly pointed out the Government’s strong interest in officer safety. As we noted in
Holt,
The line of cases Defendant cites in his brief concerning an officer’s request for consent to search a vehicle before the officer returns the driver’s license, registration, and insurance information does not alter the outcome of this case.
See e.g., United States v. Guerrero-Espinoza,
AFFIRMED.
Notes
. The Utah statute at issue in Gregory, Utah Code Ann. § 41-6-61(1), required that a vehi-ele be operated "as nearly as practical entirely within a single lane....”
. As a final note, we point out that the fact Detective Baxter asked for consent to search the car instead of some other question is irrelevant.
Alcaraz-Arellano
makes clear that the content of an officer’s questions is unimportant so long as the questions do not unreasonably delay the stop. We could not have been more clear when we held that questioning “regardless of the topic” does not violate the Fourth Amendment so long as it does not prolong the detention.
