Loading and dimensions for C1 vehicles
What the exam tests
Loading and dimensions tests legal limits and safe load securing for C1 vehicles: width, height, length, overhang, axle distribution and lashing.
Core rules
- General max width is 2.55 m, height 4.0 m, lorry length 12 m and combination length 18.75 m. Refrigerated bodies may have a small width allowance; check the vehicle documents.
- Load must be secured so it cannot shift, tip or fall. Use rated straps and the EN 12195-1 principles: lashing capacity, friction and number of lashings.
- Distribute load evenly and low. Heavy items go over or between axles, not behind the rear axle.
- Do not exceed axle loads or total weight. Mark projecting loads according to the rules.
Worked example
You load 1,500 kg of pallets on a 7,500 kg C1 lorry. The rear axle is already near its limit. Placing the pallets at the tailgate increases rear-axle load and reduces steering-axle grip. Correct: place them forward, over the rear axle or slightly ahead, then check axle loads and secure with at least two straps across the load. If the load can slide, add friction mats or use direct lashing.
Traps
Do not assume a strap’s breaking strength equals its lashing capacity. Do not secure only the pallet, not the goods. Do not forget load height at bridges. Do not let load overhang without marking. Do not rely on the tailgate to hold load.
