What color are the flashing lights on snow removal vehicles?

Flashing lights on snow removal vehicles are yellow, which serves a specific purpose in enhancing visibility during winter conditions. The use of yellow lights indicates caution and warns other drivers to maintain a safe distance while the vehicle is actively clearing the roads of snow and ice. This is especially important as snow removal vehicles may move slowly or stop unexpectedly, and the yellow lights allow other roadway users to recognize these vehicles from a distance, encouraging safe driving behavior around them.

Other colors used by emergency vehicles or for different purposes include red for emergency services, blue for law enforcement, and green typically for volunteer fire services, but in the context of snow removal, yellow is the standard and most recognized color.
