What should you do?
If you drive a heavy vehicle over the stated weight, find another route; car drivers can continue but may notice a diversion signed for heavy vehicles.
How to recognise it
A red ring containing a black lorry with 7.5t written on its body, with no diagonal bar.
Common confusion
It is different from the weight-based No entry for large vehicles sign, which has a red diagonal bar through the lorry.
