CDifficulty 3/5

After immobilising a 5,500 kg MAM lorry on a significant uphill gradient, the driver leaves the seat. In addition to the parking brake and first gear (or P), how can it be secured if no suitable chocks are available and there is a kerb?

Correct answer

Resting a steered wheel against the kerb and turning it towards the centre of the carriageway.

Rest a steered wheel against the kerb with the wheels turned towards the centre of the carriageway. This is additional to applying the parking brake, stopping the engine, disconnecting the starting system and engaging first gear or the parking position as applicable. Do not use stones or branches as chocks. On a downhill gradient the wheels face outwards.
