Hazard flashers normally operate both sides of the vehicle's turn-signal system together. The dashboard arrows may flash at the same time, which differs from the single-side indication used for an ordinary turn.
While safely parked, confirm that the exterior lamps respond as expected. Hazard flashers do not make a dangerous stopping location safe. If the lights behave inconsistently, note which lamps fail or remain on and contact 12th Street Auto Care Center in Sioux Falls.
