Defendant Mario Arreola-Botello was lawfully stopped for failing to signal a turn and a lane change. During the stop, while defendant was searching for his registration and proof of insurance, the officer asked him about the presence of guns and drugs in the vehicle, and requested consent to search the vehicle. Defendant consented, and during the search, the officer found a controlled substance. Defendant contended that the officer expanded the permissible scope of the traffic stop when he asked about the contents of the vehicle and requested permission to search it because those inquiries were not related to the purpose of the stop. The Oregon Supreme Court concurred with defendant that the trial court erred in denying defendant’s motion to suppress what the officer found, and reversed the decision of the Court of Appeals.
