249. Emergency vehicle lighting
Emergency vehicle lighting consists of special flashing or rotating lights used on authorised emergency or priority vehicles to make them highly visible and warn other road users. Police vehicles, ambulances, fire engines and other authorised response vehicles commonly use distinctive warning lights when responding to incidents.
The colour, meaning and permitted use of emergency lights vary between countries. When emergency lighting is active, road users should remain alert, identify the approaching vehicle and follow the local rules for giving way or creating a clear passage.
