Hazard warning flashers generally operate the left and right turn-signal lamps together. Both dashboard arrows may flash, showing a different pattern from a single turn signal. This is normally a status indication rather than an engine or braking warning.
Learn the location of the hazard switch before you need it. Use the lights appropriately for the situation, remembering that flashers do not make an unsafe stopping position safe.
If a lamp stays dark, remains on, or behaves differently from the others, check its operation while safely parked. Tell The Car Clinic of Miami which exterior lamps and dashboard indicators are affected.
