A green flashing beacon on a vehicle means the driver or passenger is a doctor on an emergency call. Give way to them if it's safe to do so. Be aware that the vehicle may be travelling quickly or may stop in a hurry.
Amber beacons are usually for slow-moving vehicles: motorway maintenance, snow plough, breakdown recover
Blue beacons for emergency vehicles: police, ambulance, fire engine, or other emergency vehicles
Green beacons for doctors (POZA masina doctor)
