105. Emergency vehicle lighting
Emergency vehicle lighting consists of special flashing or rotating lights used on authorised emergency or priority vehicles to make them highly visible and warn other road users. Police vehicles, ambulances, fire engines and other authorised response vehicles commonly use distinctive warning lights when responding to incidents.
The colour, meaning and permitted use of emergency lights vary between countries. When emergency lighting is active, road users should remain alert, identify the approaching vehicle and follow the local rules for giving way or creating a clear passage.

Which warning lights do priority vehicles use in Belgium?
Belgian priority vehicles are equipped with one or more blue flashing lights together with a special audible warning device.
When must a Belgian priority vehicle use its blue flashing lights?
The blue flashing lights must be used during an urgent mission. They may also be used during another mission when the nature of that mission justifies their use.
Do blue flashing lights alone require you to give way in Belgium?
The specific obligation to immediately clear the way and give priority applies when the approaching priority vehicle uses its special audible warning device. When blue lights are visible without the siren, road users should remain alert and avoid obstructing the vehicle.
