Cargo Securing, Load Limits and Vehicle Dimensions
What this domain tests
This domain tests whether you can secure a load so it cannot move, and whether you know the dimension and weight limits that apply to Norwegian heavy vehicles.
Core rules
- Secure cargo against forces of about 0.8 g forward and 0.5 g sideways and rearward. Friction alone is rarely enough; use certified straps, chains or blocking.
- Lashings need a direct angle and edge protection. Check the load again after the first 10–20 km and during the journey.
- Do not exceed the vehicle's permitted gross weight, axle loads or payload. Axle overload can occur even when total weight is legal.
- Normal maximum dimensions are about 2.55 m width, 4.0 m height and 24.0 m combination length. Refrigerated bodies and special permits can allow exceptions; longer modular combinations operate only under permit on specified routes.
- A load must not obscure lights, reflectors, registration plates or the driver's view.
Worked example
A 1,000 kg pallet sits on a steel deck. The friction is low, so two straps alone may not meet the forward-force requirement. Correct approach: use blocking or a certified lashing arrangement with edge protectors, calculate the required lashing capacity from the strap rating and friction, and recheck tension after driving.
Traps that cost marks
Assuming the strap's label rating is the same as the force it actually holds. Ignoring friction and lashing angle. Checking only total weight, not axle loads. Forgetting that an overhanging load may need marking and that height must include the load.
Key points
- Cargo must withstand 0.8 g forward and 0.5 g sideways and rearward.
- Use certified equipment, edge protection and recheck after 10–20 km.
- Total weight and individual axle loads must both be legal.
- Normal limits: about 2.55 m wide, 4.0 m high and 24.0 m long.
- Never obscure lights, plates or the driver's view.
