Vehicle weight limits

Weight limits define the maximum total mass a vehicle can have when fully loaded, including both the vehicle itself and its cargo. These limits are essential for road safety and to prevent damage to infrastructure.

In general, for simpler vehicles, the maximum mass depends on the number of axles. A vehicle with one axle cannot exceed 5 tons, with two axles 8 tons, and with three or more axles 10 tons. However, modern vehicles equipped with suitable tires may be allowed higher limits.

For single motor vehicles with tires that properly distribute weight, the maximum mass can reach 18 tons for two-axle vehicles and 25 tons for vehicles with three or more axles. Under certain technical conditions, such as pneumatic suspension or special axle configurations, these limits may increase up to 26 or 32 tons. For buses and trolleybuses with two axles, the limit is 19.5 tons.

For vehicle combinations such as road trains and articulated vehicles, higher limits apply. A three-axle road train can reach up to 30 tons, while combinations with four axles can reach 40 tons and those with five or more axles up to 44 tons.

There are also specific limits for axle loads. No single axle may carry more than 12 tons. When two axles are close together, the combined weight allowed depends on the distance between them. The closer the axles, the lower the allowed total weight, to reduce pressure on the road surface.

If a vehicle exceeds the permitted weight limits, it cannot circulate normally and penalties apply. It is therefore important to ensure that the load is properly distributed and within legal limits.

For the theory exam, it is essential to understand that weight limits depend on the number of axles, vehicle type, and technical characteristics, and that respecting these limits is crucial for safety.
