Drive AWD/4WD vehicles on unsealed roads

This unit describes the performance outcomes, skills and knowledge required to use appropriate range, gear and techniques to drive a four wheel drive or all wheel drive on unsealed roads to deliver personnel or equipment to activity sites. It covers driving on graded formed dirt roads with slight to moderate inclines and small forded water crossings. Driving must be carried out according to the licensing, certification requirements of the relevant State or Territory authority.

Application

This unit applies to those required to delivering personnel or equipment to activity sites and those undertaking inspections along a route.

This unit may also apply to leaders working for outdoor education or adventure providers; volunteer groups; not-for-profit organisations or government agencies.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the following is essential:

safe and efficient AWD or 4WD vehicle operation over formed roads

determines the different characteristics and features of a range of AWD and 4WD vehicles and performs pre start checks

changes wheels, performs shut down procedures and completes all required documentation including reporting faults and any required maintenance.

Context of and specific resources for assessment

Assessment must ensure application of driving techniques to negotiate formed dirt roads and small inclines to 15 degrees on sufficient occasions to demonstrate competency and consistency of performance.

Assessment must also ensure access to:

a suitable environment with formed dirt roads and inclines

a suitable AWD or 4WD vehicle

legislation and organisational policies and procedures that impact on the conduct of driving activities.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

observation of safe and efficient AWD or 4WD vehicle operation over formed dirt roads

oral or written questioning to assess knowledge of vehicle operating systems and associated risks and procedures for reporting maintenance requirements

third-party reports from a supervisor detailing performance.

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
