What lights should be shown on a parked car; tractor or works vehicle at night on an unlit public road?

Correct Answer

At least one side lamp front and rear on the side nearest the centre of the road.

Explanation: When leaving a vehicle on an unlit public road at night this creates a potential danger for other road users. Drivers should therefore leave side/parking lights on; so that the vehicle can be seen by other road users. Drivers should not leave headlights on when parked as this may cause other road users to become disoriented.
