What colour lights do emergency vehicles display?

Emergency vehicles display red, white, and/or blue lights to signal their presence and alert other road users. The use of these colors serves specific purposes; red is predominantly used to signify urgency and danger, catching the attention of drivers and pedestrians quickly. White lights can be used for additional visibility, particularly in dark conditions, while blue lights are often used by police vehicles to distinguish them from other emergency services and enhance visibility during critical situations.

The combination of these colors helps ensure that emergency vehicles can be easily recognized on the road, facilitating a swift response to emergencies while managing traffic effectively. Knowing this distinction is vital for the safe operation of vehicles within and around an airport environment like Vancouver International Airport, as it helps all operators identify and yield to emergency situations promptly and appropriately.
