PassAxle Mass Limit
Where: Before bridges, culverts, causeways and weight-restricted structures, and on roads whose surface cannot carry heavy axle loads.
Purpose: To prohibit any vehicle that carries more than the indicated mass on a single axle from proceeding. Note what is being limited: not the mass of the whole vehicle, but the load pressing down through one axle.
Action Required by Driver: If any axle of your vehicle exceeds the figure shown, you may not pass the sign — find an alternative route. A load that is legal in total can still break this limit if it is badly distributed, so it is the loading that matters, not only the weighbridge total.
Not the same as the mass limit sign
We also carry the mass limit sign, which restricts the total mass of the vehicle. The axle mass limit restricts the mass on one axle. A long vehicle spreading its load over many axles may pass an axle limit it would fail if the same load sat on two axles.
The figure on the sign is an example
This sign is a template. The number printed on the real sign is set by the road authority for that particular road, bridge or structure, so always read the figure in front of you rather than remembering the one shown here.
