What it means
Temporary Prohibition: Vehicles heavier than the limit shown are temporarily banned from this road surface.
What to do
- Weigh or estimate honestly before the restriction; turning on a verge damages roads and risks rollover.
- If over mass, use the signed detour.
- Conditions have changed here: obey this temporary sign even where it contradicts the permanent signs you know.
In the K53 test
Yellow background means temporary: it overrides the permanent version wherever they disagree. Different from axle limit: total mass vs per-axle loading.
Where you will see it
On any public road; the mass restriction applies from the sign.
