Can police ask about licensing restrictions during a traffic stop? State v. Adamson Explained

The Utah Court of Appeals addressed an important question about the scope of traffic stops in State v. Adamson, clarifying when officers may inquire about compliance with licensing restrictions without exceeding constitutional boundaries.

Background and Facts

Trooper McCoy stopped Adamson for traffic violations including a non-functional license plate light and failure to signal. During a routine computer check, the officer discovered Adamson was an alcohol-restricted driver required to maintain an ignition interlock device. When McCoy returned to ask about the device, he smelled alcohol on Adamson. Field sobriety tests revealed a blood alcohol level of 0.26, over three times the legal limit. The district court suppressed this evidence, finding the inquiry about the interlock device impermissibly expanded the traffic stop.

Key Legal Issues

The central issue was whether asking about compliance with licensing restrictions discovered during a lawful computer check constitutes an expansion of the traffic stop requiring reasonable suspicion of additional criminal activity, or falls within the permissible scope of the original detention.

Court’s Analysis and Holding

The court held that officers may conduct brief inquiries to confirm compliance with licensing restrictions without expanding the traffic stop’s scope. The court reasoned that if officers were precluded from following up on licensing restriction information, the permissible computer check would be meaningless. The inquiry about the interlock device was a natural follow-up to confirming Adamson’s driving privileges and imposed no additional intrusion beyond what he was already lawfully subjected to during the stop.

Practice Implications

This decision provides clear guidance for law enforcement and defense counsel. Officers may ask brief questions about compliance with licensing restrictions discovered during routine computer checks without needing reasonable suspicion of additional criminal activity. However, the court limited its holding to the specific facts and emphasized that any such inquiry must remain temporary and necessary to effectuate the stop’s purpose. Once the officer smelled alcohol, reasonable suspicion arose to justify further investigation through field sobriety testing.
