Unit Descriptor

This unit involves the skills and knowledge required to operate a four wheel drive vehicle safely in a range of conditions. These include driving a four wheel drive vehicle on normal roads, traversing slopes, ascending and descending steep slopes and stall recovery. It also includes operation of the vehicle in rugged terrain, the use of a jack and the completion of all pre- and post-operational checks. Assessment of this unit may be undertaken within a licensing examination conducted by, or under the authority of, the relevant state/territory road traffic authority.

Application of the Unit

Driving must be carried out in compliance with the licence requirements and regulations of the relevant state/terrritory roads and traffic authority.

Driving is performed with limited or minimum supervision, with limited accountability and responsibility for self and others in achieving the prescribed outcomes.

Driving involves the application of four wheel drive vehicle operating principles and procedures to maintain the safety and operation of a commercial four wheel drive vehicle across a variety of on-road and off-road contexts.
