Technical Standards and Road Safety
Core concepts
Technical standards cover vehicle roadworthiness, dimensions and weights, and safety equipment. Know the periodic technical inspection regime in Belgium, the rules on maximum authorised dimensions (length, width, height) and weights (maximum 40 tonnes for a standard combination, with exceptions), and the rules on axle loads. Understand the requirements for tyres, brakes, lighting, and the tachograph.
Road safety
Know the rules on load securing, the obligation to secure cargo, and the consequences of overload. Understand the driving and rest rules as safety instruments, the rules on speed limits for heavy vehicles, and the specific rules for tunnels and dangerous goods. Know the obligations in case of an accident and the use of warning equipment.
Traps
Questions often confuse the maximum authorised weight with the maximum axle load, or forget that an oversize transport requires an authorisation. Another trap is the technical inspection frequency, which depends on the age and type of vehicle. Watch for questions on load securing where the answer depends on the type of load.
Worked rule of thumb
For a standard articulated combination, the maximum authorised mass is 40 tonnes; if the load exceeds this, an exceptional transport authorisation is required. Always check the axle load limits separately, since a vehicle can be within total weight but overload an axle.
