How to recognise the axle mass restriction sign
A red-bordered disc showing a figure for the mass on a single axle.
Where you will see it
On any public road where axle loads would damage the surface.
What to do when you see it, step by step
- If any axle of your vehicle carries more than the figure in tonnes, take another route.
The common mistake
Overall mass can be within limits and still overload one axle, so check how the load is distributed.
