A car with a flashing green beacon signifies what?

A car with a flashing green beacon is specifically used to signify a medical emergency from on-duty doctors. This beacon alerts other road users that the vehicle is responding to a medical situation, which may require urgent attention, thereby allowing the doctor to reach the scene as quickly as possible.

In the context of road safety and awareness, recognizing this signal is important for drivers to give way to these vehicles, ensuring that medical professionals can perform their critical roles in emergencies. Other services, such as emergency road services, police vehicles, or fire service vehicles, utilize different colored beacons, usually blue, amber, or red, to indicate their specific functions and roles on the road. Understanding these distinctions helps promote safety and collaboration on the roads, particularly in emergency situations.
