AU Heavy Vehicle Knowledge Exam Questions & Answers 2026 (11–20)

Question 1

Who bears the primary legal responsibility for completing and maintaining a National Driver Work Diary under the HVNL?

TheoryPractice · Accepted Answer

The driver of the heavy vehicle. Under the HVNL it is the driver who is primarily responsible for accurately completing every entry in their National Driver Work Diary.

Question 2

Under the HVNL, on which of the following vehicles is a driver MOST likely to be required to keep a National Driver Work Diary?

TheoryPractice · Accepted Answer

A 12-tonne rigid truck on an interstate overnight run. The work diary requirement under the HVNL applies to drivers of heavy vehicles (GVM over 4.5 t) travelling beyond a 100 km radius of their base; an interstate overnight run in a 12-tonne truck clearly meets both criteria.

Question 3

Under the HVNL standard hours option, what is the maximum total work time permitted in any 24-hour period?

TheoryPractice · Accepted Answer

12 hours. The HVNL standard hours option caps total work time at 12 hours in any rolling 24-hour period, leaving sufficient time for mandatory rest.

Question 4

Under the HVNL Chain of Responsibility for fatigue management, which of the following parties does NOT share legal responsibility for ensuring a driver is not fatigued?

TheoryPractice · Accepted Answer

A mechanic who carries out routine tyre rotation on the vehicle. Chain of Responsibility obligations attach to those who have influence over transport tasks — schedulers, consignees, consignors and operators — but a mechanic performing routine servicing has no influence over how or when the driver works.

Question 5

Under the HVNL standard hours option, what is the minimum night rest period (continuous stationary rest) a driver must obtain in every 24-hour period?

TheoryPractice · Accepted Answer

7 continuous hours. The HVNL standard hours rules require every driver to obtain at least 7 continuous hours of stationary rest in each 24-hour period as their night rest.

Question 6

A scheduler instructs a driver to complete a delivery run that, given realistic travel distances and conditions, can only be accomplished if the driver exceeds HVNL standard hours work limits. Under the HVNL Chain of Responsibility, what is the scheduler's legal position?

TheoryPractice · Accepted Answer

The scheduler may be prosecuted for a fatigue-related offence because the schedule made compliance with work and rest limits impossible. The HVNL Chain of Responsibility means a scheduler who creates a schedule that makes it impossible for the driver to comply with fatigue management laws can personally face prosecution, even without a crash.

Question 7

Under the HVNL standard hours option, a driver reaches their maximum accumulated work hours for a work week. What must the driver do before the weekly work-time accumulation can recommence?

TheoryPractice · Accepted Answer

Take a continuous 24-hour period of stationary rest. Once a driver has reached the HVNL standard hours weekly work limit, they must complete a reset rest of at least 24 consecutive hours of stationary rest before their work-time accumulation clock restarts.

Question 8

Under the HVNL, which statement correctly describes a driver who is genuinely exempt from keeping a National Driver Work Diary?

TheoryPractice · Accepted Answer

They must still comply with work and rest time limits, and their operator must keep records of their work and rest times. Diary exemption does not remove the underlying obligation to comply with HVNL work and rest limits; the operator must record and monitor the exempt driver's hours to ensure compliance.

Question 9

Under the Heavy Vehicle National Law (HVNL), what does the term 'Gross Vehicle Mass' (GVM) refer to?

TheoryPractice · Accepted Answer

The maximum loaded mass of a single vehicle, as specified by the manufacturer. Under the HVNL, GVM is the maximum loaded mass of a single vehicle as specified by the manufacturer, covering the vehicle itself plus its payload.

Question 10

What is the primary purpose of the load restraint performance standard set out in the Load Restraint Guide published by the NHVR and National Transport Commission?

TheoryPractice · Accepted Answer

To ensure loads cannot shift, tip, or fall from a vehicle under normal driving and foreseeable emergency conditions. The load restraint performance standard requires that loads be restrained so they cannot shift, tip, or fall from the vehicle under the forces encountered in normal driving and foreseeable emergency situations.
