What type of emergency lights are designated for police cruisers?

Police cruisers are designated to use red and blue emergency lights to distinguish themselves clearly as emergency responders. The combination of red and blue is recognized universally as signaling the presence of law enforcement, enabling other drivers to identify and yield to these vehicles. This color scheme is part of a standardized practice which enhances the safety of both police officers and the public, as it provides a visual cue of authority and urgency on the road.

Amber lights are typically used by other types of emergency vehicles like tow trucks or service vehicles but do not carry the same legal implications of police presence. Red and yellow, as well as white and clear lights, do not convey the same immediate recognition of law enforcement authority and are often used in different contexts, such as traffic control or construction zones. The specific use of red and blue lights helps ensure that law enforcement can operate effectively while managing public safety.
