What Do Green Lights on Vehicles Mean? A Guide to Medical Transport Cars

When you are stopped at a red light, it is easy to assume that every vehicle approaching from behind follows the same familiar patterns of emergency lights. Most drivers immediately recognize red and blue flashing lights as signals of police, fire, or ambulance vehicles that require immediate attention and right-of-way.

However, in some regions, drivers may occasionally notice a different kind of signal: a flashing green light. Unlike sirens or emergency strobes, this light does not indicate a high-speed emergency response.
