A load that projects more than one metre backwards must always be marked.
A load that projects forwards must always be marked, the only exception is if the load is clearly visible and does not project more than one metre.
As long as the total width of the car and the load does not exceed 260 centimetres the load may project a maximum of 20 centimetres sideways on either side. A load that projects sideways does not need to be marked.
During daylight, projecting loads should be marked with a red-yellow flag at both the front and the rear.
During darkness, projecting loads should be marked with a white light and a white reflector at the front and a red light and a red reflector at the rear.
