Appellant Phillip Pulliam is charged with one count of possession with intent to distribute five kilograms of cocaine in violation of 21 U.S.C. § 841(a)(1). The cocaine was uncovered during a search of his vehicle. Pulliam filed a motion to suppress the evidence from that search, contending that the search violated his Fourth Amendment rights. After holding an evi-dentiary hearing, the district court denied the motion. Pulliam appealed the order denying his motion to suppress. We agree with the district court and affirm.
I.
On August 29, 1999, Corporal Karl Byrd of the Arkansas State Police was patrolling Interstate 40 in his marked state trooper vehicle. At approximately 1:50 a.m., he saw a silver car with a Tennessee license plate abruptly correct its course on the highway. Byrd suspected that an abrupt lane change at that hour of the day indicated driver fatigue or intoxication. He followed the silver car in his marked state trooper vehicle for two miles. During that time, Byrd saw the silver car cross the fog line, the solid white line that separates the shoulder from the highway, twice.
Byrd believed that the driver had violated Arkansas law by crossing the fog line. He pulled the driver over. The car was driven by Pulliam, an African-American male. An African-American female and an infant were passengers. Byrd told Pul-liam of the reason for the stop and asked for his license and registration. After Pul-liam produced his driver’s license and rental car agreement, Byrd asked Pulliam to come sit in his patrol car. Byrd told Pul-liam that he was going to issue him a warning ticket for improper lane use. Byrd testified that by this point he no longer suspected Pulliam of driving under the influence of alcohol. There was no problem with the rental agreement and a computer check on Pulliam’s license did not reveal any outstanding warrants.
While Byrd was writing out the ticket for Pulliam’s traffic violation, he began talking to Pulliam. Byrd testified that Pulliam seemed nervous. Pulliam told Byrd that he had taken his aunt to North Little Rock. Pulliam could not say where his aunt’s home was, but said that he knew how to get there. Pulliam also said that the woman in the car was his girlfriend and the infant was his child.
The evidence is unclear as to what happened next. Either Byrd gave the driver’s license and rental agreement back to Pul-liam before going to talk to the passenger or Byrd first talked to the passenger and then returned to the patrol car and handed the license and agreement back to Pulliam. Byrd stated that he questioned the passenger to verify Pulliam’s story. The passenger’s story conflicted with Pulliam’s. She said that she was only Pulliam’s friend, that they were visiting an uncle in Little Rock, and that the child was not Pulliam’s.
According to the district court’s findings of fact, Byrd returned Pulliam’s license and rental agreement, and then asked if he could search Pulliam’s vehicle. Byrd showed Pulliam a consent form, which stated that Pulliam did not have to consent and that he was free to leave. Byrd himself told Pulliam that he was free to leave. Nevertheless, Pulliam agreed to the search. According to the district court’s findings of fact, only after obtaining con *739 sent to the search, Byrd radioed another unit with a drug detection dog to assist in the search.
Byrd began his search. He found a large decorative bag that contained a heavy wrapped package that smelled of detergent. Byrd knew that detergent is often used as a masking agent for illegal controlled substances. Byrd placed the package on the ground outside the car. The drug sniffing dog ran around the package, then began licking at the package and biting it.
Byrd then picked up the package and placed it on the hood of his patrol car. As he was about to open it, Pulliam stepped out of the patrol car and said, “You can’t open that.” Byrd explained that he had probable cause to open the package. Pul-liam then stated that the package was not his. Byrd opened the box and found a large amount of cocaine poured into a Tide detergent box. Pulliam was arrested.
After the district court rejected Pul-liam’s motion to suppress, he entered a conditional guilty plea under Rule 11(a)(2) of the Federal Rules of Criminal Procedure. The court sentenced him to 120 months of imprisonment and five years of supervised release. A few days after the entry of judgment, Pulliam filed this appeal.
This Court examines the factual findings underlying the district court’s denial of a motion to suppress for clear error.
See United States v. Clayton,
II.
It is well-established that a traffic violation, however minor, creates probable cause to stop the driver of a vehicle.
See United States v. Beck,
Pulliam suggests that Byrd targeted him because he fit the profile of a drug trafficker. Conducting a search solely because a suspect fits a drug courier profile violates the Fourth Amendment.
See Garrett v. Goodwin,
III.
Pulliam contends that even if the traffic stop was legal, Byrd violated his Fourth Amendment rights by continuing to detain him after he had finished- investigating the traffic violation. Byrd asked for Pulliam’s license and registration, wrote up a traffic ticket, and questioned Pulliam about his trip while Pulliam was in the back of his squad car. Byrd had a right to do all of these things. See United States v. Ramos, 42 F.Sd 1160, 1163 (8th Cir.1994) (holding that a reasonable investigation of a traffic stop typically includes asking for a license and registration, asking the driver to sit in the patrol car, and asking about destination and purpose of travel).
Byrd next either held on to Pulliam’s license and registration while he interrogated Pulliam’s passenger or returned the license and registration and then interrogated the passenger. Either way, Byrd continued to detain Pulliam after he had completed the purposes of his initial traffic stop. Unless events transpired during the traffic stop that gave rise to a reasonable suspicion justifying Byrd’s continued detention of Pulliam, Pulliam’s Fourth Amendment rights were violated.
See Beck,
In either scenario, Pulliam’s answers to Byrd’s questions gave him the reasonable suspicion needed to justify expanding the scope of his investigation to interrogate Pulliam’s passenger. Pulliam stated that he had taken his aunt to Little Rock, but could not remember where she lived. Contradictory statements establish the reasonable suspicion necessary to detain a motorist further and to interview passengers.
See United States v. Edmisten,
After Byrd questioned Pulliam and his passenger and returned Pulliam’s license and registration, Byrd asked Pulliam for permission to search his car. The issue is whether Pulliam’s consent to the search was consensual. If the search and Pul-liam’s decision to remain with Byrd were consensual, then there was no Fourth Amendment violation. But if a reasonable person would not have believed himself free to leave, then the search was not consensual.
See Beck,
An unlawful seizure does not occur just because an officer approaches an
*741
individual to ask some questions or requests permission to conduct a search. This is true even if the officer has no reason to suspect the individual of unlawful activity.
See United States v. White,
None of those circumstances existed here. Byrd told Pulliam that he did not have to consent to the search and was free to leave. Even Pulliam admits that Byrd told him several times that he was free to go. Although an officer is not obligated to inform a suspect of his right to refuse consent to a search, an officer’s decision to provide such information is a “significant” factor in determining voluntariness.
United States v. Zamoran-Coronel,
AFFIRMED.
Notes
. Byrd testified at trial that he thought that he had enough suspicion to detain Pulliam's vehicle until the drug sniffing dog arrived
even if Pulliam did not consent to a search.
Pul-liam also argues that because his signature is not on the traffic ticket, we must infer that Byrd never returned his license and rental agreement and thereby held him against his will. The district court found, however, that Byrd did not tell Pulliam that he would detain the car until the drug dog arrived and that Byrd did, in fact, return Pulliam’s license. We see no reason to dispute the findings of the district court.
