It is used to manage safety, protect vulnerable users, reduce conflict, or keep unsuitable vehicles and behaviour out of a particular road environment.

Whenever a supplementary plate is present, it tells you exactly which vehicles, times, distances, or conditions the ban covers.
This sign prohibits or restricts limited gross vehicle weight from the point where it applies. Drivers must obey the restriction immediately and look for any supplementary plate or end sign that explains the scope, duration, or exceptions.

The 318.1 sign means that vehicles with a gross weight exceeding the limit shown on the sign (or a generally applicable limit if no specific weight is shown) are not allowed to proceed past the sign. This is a restriction designed to protect roads, bridges, or specific areas from damage or congestion caused by excessively heavy vehicles.
If your vehicle's gross weight exceeds the limit indicated by the sign or by supplementary plates, you must not proceed past the sign. You should find an alternative route or make a different manoeuvre that complies with the restriction. Always check for supplementary plates, as they can specify the exact weight limit or the types of vehicles affected.
Yes, exceptions can often be found on supplementary plates accompanying the main 318.1 sign. These plates might specify that the restriction only applies to certain types of vehicles, during specific times, or that it ends after a certain distance. If no supplementary plate is present, the restriction typically applies from the sign onwards until cancelled.
A common mistake is to ignore the sign if the road appears clear or if the driver believes their vehicle is not that heavy. Another trap is overlooking supplementary plates, which provide crucial details about the restriction. Drivers might also forget that the restriction usually applies immediately from the sign, not after a short distance.
The 318.1 sign specifically limits the *gross vehicle weight*, meaning the total weight of the vehicle plus its load. Other signs might restrict axle weight or total length. It's essential to understand what type of weight restriction is being imposed to ensure compliance and safety.
