Background
David Ray Roberts entered a no-contest plea to possession of methamphetamine as a repeat offender after the circuit court denied his motion to suppress drugs found in his vehicle. An officer stopped Roberts at about 11:00 p.m. after observing what appeared to be nonfunctioning registration-plate lamps and an illegible temporary paper plate. The officer also observed a defective exhaust system.
During the stop, the officer learned that Roberts and his passenger had suspended licenses and drug-related criminal histories. While the officer was processing three traffic matters and receiving record-check information from dispatch, a K9 unit arrived 33 minutes after the stop. The dog alerted on the vehicle, and officers found a scale and suspected contraband. The plate lamps later proved to be working but dim because mud or dirt obscured them.
The Court’s Holding
The Wisconsin Court of Appeals affirmed. It held that the initial stop was supported by reasonable suspicion. The circuit court’s finding that the officer had come within 50 feet of the vehicle when observing the plate lamps was not clearly erroneous, and the officer’s apparent observation that no plate lamp was working supported reasonable suspicion even though the lamps were later found to be obscured rather than inoperable.
The court also held that the stop was not unlawfully prolonged for the canine sniff. The officer was still conducting ordinary traffic-stop tasks—processing tickets and receiving dispatch information about the occupants’ records—when the K9 arrived. Given the multiple traffic violations and continuing record checks, any nontraffic questioning did not measurably extend the detention.
Key Takeaways
- Reasonable suspicion may rest on an officer’s reasonable, contemporaneous observation of an apparent equipment violation, even if its precise cause is later discovered to be different.
- Record checks of drivers and passengers are ordinary tasks incident to a traffic stop.
- A canine sniff does not violate the Fourth Amendment when it occurs without extending the stop beyond the time reasonably needed for its traffic-related mission.
Why It Matters
The decision applies Rodriguez’s rule against prolonging traffic stops for dog sniffs while recognizing that a stop may reasonably take longer when officers are addressing multiple violations and awaiting routine dispatch information. The court did not reach the State’s alternative inevitable-discovery and additional-reasonable-suspicion arguments.
