[¶ 1] Ernest J. Donatelli appeals from a judgment of conviction of one count of unlawful trafficking in scheduled drugs (Class B), 17-A M.R.S. § 1103(1-A)(A) (2009), and one count of illegal importation of scheduled drugs (Class C), 17-A M.R.S. § 1118(1), (2)(A) (2009), entered in the Superior Court (Androscoggin County, Mar-den, J.) upon his conditional guilty plea. Dоnatelli contends that the court erred in denying his motion to suppress cocaine seized during a warrantless search of his vehicle. He argues that this evidence should have been suppressed because it resulted from an illegal de facto arrest. We affirm the judgment.
I. BACKGROUND
[¶ 2] The record reveals the following facts, which are not in dispute. On September 29, 2008, at approximately 12:30 p.m., Maine Drug Enforcement Agent Terrence McCormick received a telephone call from a confidential informant claiming that Donatelli would be “returning from Massachusetts with a supply of cocaine.” The informant did not specify the precise time Donatelli would be returning to Maine, but told McCormick that Donatelli had left Massachusetts earlier that morning. Although the informant provided no further *240 details, McCormick was familiar with Do-natelli’s vehicle based on a prior investigation and arrest, and knew that Donatelli was originally from Massachusetts. Additionally, approximately two years earlier, McCormick had been informеd by two separate sources that Donatelli was a distributor of cocaine. McCormick was also generally aware that Massachusetts is a major point of distribution from which cocaine is transported to Maine.
[¶ 3] At the time of the Donatelli tiр, McCormick had been working with the informant for approximately six months. During that time, the informant supplied information about four other individuals. That intelligence had led to two drug-related convictions; two other investigations were ongoing. According to McCormick, the informant was a former cooperating defendant who, in providing information about Donatelli, was “just continuing] to help.”-
[¶ 4] Immediately following his conversation with the informant, McCormick formulated a plan to intercept Donatelli on the Maine Turnpike. Because Donatelli lived in Auburn, McCormick arranged for two officers from the Auburn Police Department to wait at the Auburn exit tollbooth, while Maine State Police Troopers patrolled the interstate. Together with Maine State Trooper Matthew Casavant and Casavant’s police canine, McCormick drove in an unmarked van to the Gray exit to wait for Donatelli.
[¶ 5] At approximately 1:30 p.m., a state trooper spotted Donatelli’s vehicle traveling northbound on Interstate 95 near Scarborough. Alerted to this information, McCormick and Casavant observed Dona-telli’s vehicle twenty minutes later, and contacted Maine State Trooper Fern Clou-tier to assist them in making a traffic stop. As they followed Donatelli’s vehicle, Casа-vant noticed that the sound of the vehicle’s exhaust appeared to be in excess of ninety-five decibels and that the rear registration plate was partially obstructed, both of which are motor vehicle violations. See 29-A M.R.S. §§ 452,1912 (2009).
[¶ 6] Cloutier stoppеd Donatelli’s vehicle just north of the Auburn exit. The two Auburn officers, in separate vehicles, pulled in behind Cloutier’s cruiser. Dona-telli had a passenger with him, and both men were brought to the rear of Donatel-li’s vehicle, in front of Cloutier’s cruiser. 1 Never losing sight of Donatelli’s vehicle, McCormick and Casavant pulled their van in behind the Auburn officers. At this point, four police vehicles and five law enforcement officers were on the scene.
[¶ 7] After making sure that traffic was clear, McCormick walked over to Donatel-li’s vehicle, introduced himself, and asked Donatelli whether “there [were] any illegal drugs in his vehicle.” Donatelli responded “no,” and told McCormick that he could “go ahead and search” the vehicle. Dona-telli was calm and cooperаtive and had not been formally arrested or placed in handcuffs. Although McCormick would not have allowed Donatelli to leave, he never communicated this intent to Donatelli. Within minutes of arriving on the scene, Casavant’s police canine сonducted an exterior “sniff test” of Donatelli’s vehicle and detected the presence of narcotics. A subsequent search of the vehicle yielded evidence of cocaine.
[¶ 8] Donatelli was indicted on one count of unlawful traffiсking in scheduled drugs (Class B), 17-A M.R.S. § 1103(1-A)(A), and one count of illegal importation *241 of scheduled drugs (Class C), 17-A M.R.S. § 1118(1), (2)(A). 2 Donatelli filed a motion to suppress, arguing that the evidence found in his vehicle was obtained in violation of his constitutional rights. After a hearing, the court denied the motion tо suppress. The court determined that the informant’s history of providing accurate information and the police corroboration of certain elements of the informant’s tip, combined with Casavant’s observation of the motor vehicle violаtions, gave the officers constitutional authority to order the warrantless stop of Donatelli’s vehicle. Finding “nothing improper with respect to the number of officers involved or the circumstances in which the stop was made,” the court concludеd that both Donatelli’s consent and the positive canine sniff test justified the vehicle search.
[¶ 9] Following the court’s order, Do-natelli entered a conditional guilty plea on the two charges pursuant to M.R.Crim. P. 11(a)(2) and filed this appeal. 3
II. DISCUSSION
[¶ 10] Our review of a triаl court’s denial of a suppression motion is bifurcated. “We review the denial of a motion to suppress for clear error as to factual findings and de novo as to issues of law.”
State v. Reese,
[¶ 11] To conduct a constitutionally permissible traffic stop, an officer must have, at the time of the stop, “an articula-ble suspicion that criminal conduct has taken place, is occurring, or imminently will occur, and the officer’s assеssment of the existence of specific and articulable facts sufficient to warrant the stop [must be] objectively reasonable in the totality of the circumstances.”
State v. Burgess,
[¶ 12] “To qualify as a mere
Terry
stop, a detention must be limited in scope and executed through the least restrictive means.”
United States v. Novak,
[¶ 13] Because Donatelli concedes that law enforcement had reasonable suspicion to believe that he was transporting cocaine, we are tasked with evaluating the second prong of the analysis: whether the action taken by police was “reasonably related in scope to the circumstances which justified the interference.”
Langlois,
[¶ 14] We are persuaded that the circumstances justifying the stop of Donatelli’s vehicle, including the significant State interests in detecting illegal drug trafficking and ensuring officer safety, warranted the actions taken by law enforcement. In arguing to the contrary, Donatelli focuses primarily on the number of police officers and vehicles involved in effectuating the stop. Although we agree that this fact is certainly relevant, “[m]ere numbers do not automatically convert a lawful
Terry
stop into something more forbidding.”
United States v. Zapata,
[¶ 15] Investigative traffic stops “are especially fraught with danger to police officers.”
Michigan v. Long,
[¶ 16] After stopping the vehicle, law enforcement acted prudently in securing Donatelli’s detention. Donatelli admits that his vehicle was not blocked from leaving. Cf
. United States v. Quinn,
[¶ 17] We also find nothing unreasonable in the length and intrusiveness of the stop.
See United States v. Hensley,
[¶ 18] Because Donatelli was not subjected to a de facto arrest, we need not consider whether the informant’s tip established probable cause. In the course of conducting a valid
Terry
stop, law enforcement acquired constitutional authority to search Donatelli’s vehicle by securing Do-natelli’s voluntary consent.
See State v. Kremen,
The entry is:
Judgment affirmed.
Notes
. Although it is clear that both Cloutier and the Auburn officers approached Donatelli’s vehicle, there is no record evidence with regard to the instructions given to Donatelli as he exited his vehicle.
. Count 1 of the indictment originally charged Donatelli with aggravated trafficking in scheduled drugs (Class A), 17-A M.R.S. § 1105-A(1)(D) (2009), but was amended to reflect the correct charge of unlawful trafficking in scheduled drugs (Class B), 17-A M.R.S. § 1103(1-A)(A) (2009).
. The court sentenced Donatelli to five years of incarceration for each count, to be served concurrently, with all but one year suspended, and three years of probation.
