Road works signs

Lane closed ahead, 450 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?

Displayed on the back of a slow-moving or stationary works vehicle, this board warns that a lane is closed 450 yards ahead and that no cones have been put out. Mobile closures like this are used for short-duration maintenance where setting out cones would take longer than the work itself. Move out of the closed lane as soon as you have read the board and pass the works vehicle with plenty of room. The distance figure varies between boards, so read the number rather than recognising the shape alone.
