State v. Dawley, 2016 Ohio 2904

On April 13, 2015 Officer Nickolas Baehr (Pickerington PD) observed Dawley driving erratically on a state highway: repeated lane drifts, crossing painted lane markers, near-collision, and speeding up to 75 mph in a 60 mph zone.
Officer Baehr attempted radio contact but could not reach dispatch; a concerned motorist also reported/confirmed Dawley’s dangerous driving at the scene.
After a traffic signal stop, Baehr observed signs of impairment (glassy, droopy eyes; slurred speech; momentary nodding off); he removed Dawley’s keys and awaited an Ohio State Highway Patrol trooper.
Trooper Wilson later arrested Dawley for OVI, driving under suspension, and marked lanes violations; Dawley moved to suppress evidence obtained from the stop.
The trial court (on stipulated facts including Baehr’s narrative report) denied the suppression motion; Dawley appealed the denial and subsequently pled no contest to OVI.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the traffic stop was unlawful because Baehr (a city officer) stopped a motorist on a state highway outside municipal limits	Dawley: the stop violated statutory jurisdiction limits and Ohio Const. art. I, §14; thus evidence should be suppressed	State: the stop was justified under the community-caretaking/emergency-aid exception given dangerous driving and an immediate risk to the public	The stop was lawful under the community‑caretaking/emergency‑aid exception; suppression denied
Whether the circumstances amounted to an exigency permitting an officer outside jurisdiction to intervene	Dawley: mere minor lane violations do not permit an out‑of‑jurisdiction stop	State: multiple episodes of dangerous driving plus a citizen complaint created an objectively reasonable belief of imminent danger	Court: objective facts supported an emergency/exigency; intervention was reasonable
