GEORGIA COURT OF APPEALS EXPLAINS PRETEXTUAL STOPS AND K9 SNIFF
On September 16, 2025, the Court of Appeals of Georgia decided Ayala v. State,[i] in which the court examined a pretextual traffic stop and canine sniff to determine if the officers violated the Fourth Amendment such that the evidence obtained from the stop should be suppressed. The facts, taken directly from the case, are as follows:
[T]he evidence presented at the motion to suppress hearing showed that in December 2021 a sheriff’s investigator followed a pickup truck with a North Carolina tag when it left a suspected drug house in Georgia. While following the truck, the investigator saw the driver fail to maintain his lane multiple times. The investigator, who was in an unmarked vehicle, contacted the local police department and asked for an officer to make a traffic stop of the vehicle. The investigator watched as a police officer pulled the truck over into a store parking lot and he saw a K-9 unit arrive on the scene within five minutes.
The officer who initiated the stop testified that he heard on his radio that investigators had observed traffic violations, that he followed the truck and also observed the driver failing to maintain his lane, and that he was aware a K-9 unit had already been requested. After making the stop, the officer approached the truck and spoke to the driver, who was identified as Ayala. The officer asked Ayala for his driver’s license and told him that he had been stopped for failure to maintain his lane. Ayala replied that he had been avoiding potholes.
The officer returned to his patrol vehicle to check Ayala’s driver’s license. A backup officer arrived at the scene, began speaking to Ayala, and had him get out of his vehicle. The first officer determined through radio dispatch that Ayala’s license was valid. The officer subsequently requested that the backup officer ask Ayala if the address listed on his license was still current, which was necessary information for the written warning that the officer later wrote.
A few seconds after confirming the address, and approximately eight minutes after the truck was stopped, the K-9 unit conducted an open-air sniff around Ayala’s truck and the drug dog alerted to the presence of drugs. Officers searched the vehicle, found suspected methamphetamine, and arrested Ayala. The sheriff’s investigator then obtained a search warrant for the house, which was later executed.[ii]
Ayala filed a motion to suppress the drugs found in the car and the house. [Note: This article will not discuss the search warrant.] The trial court denied the motion to suppress and Ayala appealed to the court of appeals of Georgia.
On appeal, Ayala argued that the evidence obtained during the traffic stop should be suppressed (1) because the traffic stop was unlawful as it was an unauthorized pretextual stop and (2) because the stop was impermissibly prolonged by the canine sniff.
The Traffic Stop
The court of appeals first addressed the pretextual stop argument. The court stated
In Whren v. United States, 517 U.S. 806 (116 SCt 1769, 135 LE2d 89) (1996), the United States Supreme Court held that when an officer witnesses a traffic offense, the resulting traffic stop does not violate the Fourth Amendment even if the officer has ulterior motives in initiating the stop. Thus, where a traffic stop is based on a police officer’s observation of even a minor traffic violation, a suppression motion arguing that the stop was pretextual must fail.[iii]
In Ayala’s case, an investigator saw Ayala leave a drug house, followed him, and observed him fail to maintain his lane in violation of Georgia law, several times. The investigator radioed this information to other officers and requested an officer stop Ayala. The officer that initiated the traffic stop testified that he also observed Ayala fail to maintain his lane prior to stopping his vehicle.
The court held that even though the officer had the ulterior motive of checking for drugs when he stopped the vehicle, because the officer observed a traffic violation, the stop did not violate the Fourth Amendment.
Additionally, the stop was also conducted on behalf of the investigator, who observed Ayala fail to maintain his lane prior to the stop, and radioed that information to the officer who conducted the stop. The court noted that under the “collective knowledge doctrine,” the stop was authorized and did not violate the Fourth Amendment. The collective knowledge doctrine stands for the proposition that
The stop of a vehicle is authorized if the officer observes a traffic offense. Probable cause may be established based on the collective knowledge of the communicating officers. Wilson v. State, 318 Ga. App. 59, 62 (1) (733 SE2d 365) (2012)[iv]
Thus, because the investigator observed a traffic violation, the officer that stopped the vehicle can rely on the reasonable suspicion or probable cause obtained by the investigator.
Therefore, the traffic stop did not violate the Fourth Amendment despite the officers’ ulterior motives of conducting a drug investigation.
The Canine Sniff
Ayala argued that the traffic stop was unreasonably prolonged when he abandoned the mission of the stop without reasonable suspicion to conduct a drug investigation using a canine sniff.
The legal principle relevant to this issue is as follows:
Once a valid traffic stop has been effected, the Fourth Amendment prohibits the officer from unreasonably prolonging the stop beyond the time required to fulfill the purpose of the stop without a reasonable articulable suspicion of other illegal activity. But a reasonable time to conduct a traffic stop includes the time necessary for the officer to run a computer check on the validity of the driver’s license and registration, and to check for outstanding warrants and/or criminal histories on the driver and other occupants. The law further allows the officer to question the vehicle’s driver and/or its occupants during the course of the stop, and even to lawfully ask questions unrelated to the purpose of a valid traffic stop, so long as the questioning does not unreasonably prolong the detention. Rush v. State, 368 Ga. App. 827, 831-832 (2) (890 SE2d 883) (2023)[v]
Additionally, the court explained
[I]t is permissible to conduct an open air search around a vehicle while a traffic stop is still in progress so long as the stop has not been unreasonably prolonged for the purpose of conducting the search.” Rush, supra at 832 (2) (citation and punctuation omitted). See also State v. Allen, 298 Ga. 1, 5 (2) (a) (779 SE2d 248) (2015) (dog sniff of a traffic-stopped vehicle is not part of the officer’s traffic mission, but conducting an open air dog sniff around a vehicle during a traffic stop does not itself violate the Fourth Amendment and can be lawfully done so long as it does not lengthen the stop).[vi]
Further, the court, discussing the above case, stated that the Supreme Court of Georgia, in Allen, held
[A]ctivity unrelated to the mission of the traffic stop that is done concurrently with a mission-related activity does not unlawfully prolong the stop. Allen, supra, at 13.[vii]
The court of appeals observed that the evidence in Ayala’s case showed that the canine sniff was “conducted while [the officer was completing tasks] related to the mission of the traffic stop, the dog sniff did not prolong the stop at all.” Allen, supra at 15 (2) (d) (emphasis omitted). Thus, since the canine sniff was conducted while the officer that made the stop was writing a warning citation and occurred approximately eight minutes after the stop began, the court of appeals held the stop was not unreasonably prolonged in violation of the Fourth Amendment.
Additionally, after the canine alerted to the presence of drugs, this provided the officers with probable cause to search the vehicle. During the search, the officers located methamphetamine. The court of appeals noted
[A] drug dog’s alert on defendant’s vehicle provide[s] [a] police officer with probable cause to search. Davidson v. State, 257 Ga. App. 260, 264 (1) (b) (570 SE2d 698) (2002)[viii]
Therefore, the court of appeals affirmed the denial of the motion to suppress.
