In many places, green flashing lights are used by volunteer services, transport vehicles, or authorized support vehicles to improve visibility. They usually do not give the driver special legal rights, such as forcing traffic to move aside.
Because of this, drivers should not panic, brake suddenly, or make risky moves. The safest response is to stay calm, keep driving predictably, and remain aware of the vehicle’s position.
While you may not be required to pull over, giving reasonable space when safe can help everyone on the road. Understanding what green lights mean reduces confusion and makes driving safer for all.
