Edwin James Baker was convicted of trafficking in cocaine. His motion for new trial was denied, and he appeals, complaining in three related enumerations of error that the trial court erred in denying his motion to suppress. We disagree and affirm. We must follow three principles when reviewing a trial court’s order concerning a motion to suppress evidence: First, the judge sits as the trier of facts. The trial judge hears the evidence, and his findings based upon conflicting evidence are analogous to the verdict of a jury and should not be disturbed by a reviewing court if there is any evidence to support it. Second, the trial court’s decision with regard to questions of fact and credibility must be accepted unless clearly erroneous. Third, the reviewing court must construe the evidence most favorably to the upholding of the trial court’s findings and judgment. Citations, punctuation, and footnote omitted. State v. Hester , 268 Ga. App. 501, 502 602 SE2d 271 2004. So viewed, the evidence shows that a Carroll County sheriff’s deputy and K-9 officer was patrolling Interstate 20 when he observed a black Chevy Suburban travelling at an unusually slow rate of speed. After clocking the vehicle at 39 miles per hour, below the legal minimum speed, the deputy decided to follow the vehicle. As he followed, the Suburban left the interstate by cutting across the gore instead of following the exit lane, another traffic violation. The vehicle exited onto the state highway and into the turning lane for a truck stop, but when the police car appeared, the driver of the Suburban pulled out of the turning lane back onto the highway. Then the vehicle “abruptly” turned into a restaurant, causing the police car to go on past it when the deputy could not turn in time. Rather than parking or going around the restaurant, the vehicle turned around in the parking lot “which is kind of hard to do,” then got back onto the highway and returned to the truck stop. The vehicle “pulled up to the gas pumps and sat there.” The driver and passenger got out of the vehicle, and the driver began to walk towards the truck stop while the passenger stood by the vehicle, stretching.
Based on their unusual maneuvers, the deputy concluded that the occupants of the Suburban were trying to avoid him. He never turned on his traffic lights, did not initiate a stop, and did not order the occupants out of the vehicle, but approached the driver as he walked towards the truck stop and asked for his driver’s license. Both the driver and passenger seemed “overly nervous” to the deputy, they could not keep still, and would not make eye contact. When the deputy approached the vehicle, he noticed a strong odor of air freshener, which in his experience “that odor’s trying to cover up another odor inside of the vehicle.” Upon checking the driver’s and passenger’s licenses, the deputy found that both had criminal histories, with the driver having “a criminal and a drug history starting back in 1988.” At that time, the deputy asked them for a consent to search, “and they both granted consent without any problem.”1 Suspicious of the condition of the spare tire under the vehicle, the deputy used a “density meter” which indicated that the tire was full of solid material. After his dog alerted on the tire, the deputy opened the valve stem and smelled the odor of cocaine. Officers found thirty-six packages of cocaine inside the tire. At least three types of police-citizen encounters exist: verbal communications involving no coercion or detention; brief “stops” or “seizures” that require reasonable suspicion; and “arrests,” which can only be supported by probable cause. A first-tier encounter never intrudes upon any constitutionally protected interest, since the purpose of the Fourth Amendment is not to eliminate all contact between police and citizens, but simply to prevent arbitrary and oppressive police interference with the privacy and personal security of individual citizens. On the other hand, a second-tier encounter may violate the Fourth Amendment if the officer briefly “stops” or “seizes” a citizen without an articulable suspicion. Articulable suspicion requires a particularized and objective basis for suspecting that a citizen is involved in criminal activity. Citations omitted. Brittian v. State , 257 Ga.
