When can you use emergency vehicle lights

Using emergency vehicle lights on a police vehicle or authorized emergency vehicle can safely reduce the response time to get to an injured person or the scene of a crime. As such, strobe lights, flashing lights, red lights, blue lights, and other types of emergency vehicle lights are required by law in most US states.

Although fire department vehicles, law enforcement personnel, and ambulances en route to an emergency call can use warning lights, this doesn’t mean they are authorized to use them at their convenience. There are laws in place to ensure compliance and safety. State laws define what situation allows emergency personnel to use emergency lights.

When can you use lights

When specifically permitted, civilians, such as volunteer firefighters, physicians, and volunteer firefighters can use warning lights on their vehicles. These lights should only be used en route to an emergency call and can be placed on a private vehicle with the required permit. Colors and patterns vary by state and emergency vehicle function.
