Most candidates coped reasonably well with part (ii) by describing circumstances such as insecure and unstable loads, manoeuvring with the load elevated, colliding with kerbs and other obstructions, cornering at speed, braking harshly, driving on uneven or soft ground, and mechanical failure. Those who gained high marks for this part tended to be those who adopted a structured approach and considered the load, the environment and the vehicle itself.
