What color lights do emergency vehicles typically have?

Emergency vehicles typically use red and blue lights to signal their presence and alert other drivers on the road. The combination of both colors enhances visibility and is widely recognized as an indicator of emergency response vehicles, such as police cars, ambulances, and fire trucks.

Red lights are traditionally associated with emergency situations, indicating urgency and the need for immediate attention. Blue lights are added to this mix to increase visibility in various environments and can signify different types of emergency services depending on local laws and regulations. This dual-color system is effective in distinguishing emergency vehicles from other types of vehicles, ensuring that they can navigate traffic more easily and respond to emergencies without undue delay.

The use of other colors, such as green or yellow, does not typically signify emergency vehicles. These colors may be used for specific functions, such as construction vehicles or to indicate non-emergency services. However, they do not carry the same universal recognition or urgency associated with red and blue lights.
