If your vehicle or vehicle-and-trailer combination is longer than the figure, do not continue; use the signed alternative route.
How to recognise it
A red ring with a black lorry symbol above two pointers and the length 10.5m.
Common confusion
Compare it with the Maximum vehicle width sign, which shows pointers facing inward across a single figure and no lorry.
