125. Hazard lights
Hazard lights, also called hazard warning lights, make all of a vehicle's direction indicators flash simultaneously. They are used to warn other road users that the vehicle or traffic situation presents an unusual or immediate danger.
Hazard lights may be appropriate after a breakdown, collision or when warning following traffic of a sudden hazard. They should not normally be used as a substitute for proper parking, signalling or vehicle lighting.
