On an ordinary goods lorry without a special-transport authorisation, how must a legally projecting rear load be marked when travelling between sunset and sunrise?

Correct answer

With one or two panels (V-20) and a red light.

Use a V-20 panel at the rear extremity perpendicular to the vehicle’s longitudinal axis, plus a red light. If the load projects rearwards across the full rear width, use two panels, one at each end, forming an inverted V. The additional red light is also required when conditions substantially reduce visibility. Observe applicable projection, securing and other precautions.
