Police vehicles are a common type of marked vehicle, and they are usually marked with a police badge, flashing lights, and warning lettering.

Police cars can turn on their sirens and lights in emergencies so that they can arrive at the scene quickly and enjoy privileges on the road, such as speeding and running red lights.
Ambulances are also one of the marked vehicles; they are usually marked with the Red Cross symbol and the words Emergency Ambulance. The purpose of an ambulance is to provide medical assistance and emergency medical transportation in emergency situations. They need to move quickly through the flow of traffic, so they have special rights on the road and other vehicles need to give way.
