CDifficulty 3/5

You park a 6,000 kg MAM lorry with a manual gearbox on a 10% slope and will leave the driving position. You have already stopped the engine, disconnected the starting system and taken the other necessary precautions. Which additional set of immobilisation measures must you apply?

Correct answer

Parking brake, appropriate gear and proper chocks or prescribed kerb support.

Apply the parking brake, engage first gear uphill or reverse downhill, and use proper wheel chocks or the prescribed support of a steered wheel against a kerb. With kerb support, turn the wheels towards the carriageway centre uphill and away downhill. Chocks alone, or just the brake and gear, are insufficient in this case. Do not use stones or improvised objects as chocks; remove chocks from the road when moving off.
