Road works signs

Lane closed ahead, 800 yards

Signs used on the back of slow-moving or stationary vehicles warning of a lane closed ahead by a works vehicle. There are no cones on the road.

What does this sign mean?

This board on the back of a works vehicle warns that a lane is closed ahead by that vehicle, with the distance shown and no cones on the road. Because there are no cones, the closure is mobile and moves with the works, so the picture changes as you approach. Move out of the affected lane early, keep a good gap and do not weave between lanes to get past. The absence of cones is the detail that distinguishes these boards, and it is exactly what theory test questions ask about.
