Utah Court of Appeals
Can police continue a traffic stop after reasonable suspicion dissipates? State v. Morris Explained
Summary
Morris was stopped for failing to display a license plate and allegedly bumping the fog line while driving. Before approaching Morris’s vehicle, the officer observed a temporary permit on the SUV’s back window, eliminating the basis for the stop. The officer nonetheless approached Morris, ultimately arresting him for DUI and discovering drugs during an inventory search.

Analysis
The Utah Court of Appeals addressed a critical Fourth Amendment question in State v. Morris: whether police officers may continue to detain motorists after the reasonable suspicion justifying a traffic stop has dissipated. The court’s answer was an emphatic no, rejecting arguments based on courtesy and officer safety.
Background and Facts
Trooper Williams stopped Morris’s vehicle for two reasons: the absence of a visible license plate and allegedly improper lane travel (bumping the fog line). The state conceded that Morris’s driving pattern did not justify the stop. Before approaching Morris’s window, Williams observed a temporary permit taped to the SUV’s back window, eliminating the license plate justification. Nevertheless, Williams approached Morris, explained the reasons for the stop, and ultimately arrested him for DUI after detecting an odor of alcohol and administering field sobriety tests.
Key Legal Issues
The central issue was whether continued detention was permissible after reasonable suspicion dissipated but before initial contact with the motorist. The state argued that officers should be permitted to approach vehicles to explain mistaken stops as a matter of courtesy, citing federal circuit court dicta from United States v. McSwain.
Court’s Analysis and Holding
The court rejected the courtesy exception, emphasizing that Fourth Amendment protections cannot be subordinated to officer politeness. Once reasonable suspicion dissipates, continued detention constitutes an unreasonable seizure. The court distinguished McSwain‘s holding from its dicta, noting that the actual McSwain decision supported Morris’s position. The court held that any police detention must be justified by reasonable suspicion, and detention is no longer justified after reasonable suspicion dissipates.
Practice Implications
This decision reinforces that seizures must be both justified at inception and reasonably related in scope to the justifying circumstances. Officers cannot extend detention for explanatory purposes once the basis for a stop evaporates. Defense attorneys should carefully examine the timeline of traffic stops to identify when reasonable suspicion dissipated relative to continued detention.
