ExploreAbout this exam
The Victorian Heavy Rigid (HR) licence knowledge test is the theory-assessment step for drivers who want to move from a car or light-rigid licence into the heavy rigid class - the class that covers rigid trucks and other heavy rigid motor vehicles above the light-rigid threshold. It is aimed at people who already hold a lower class of licence, want to work in transport, logistics, construction, waste or agricultural haulage, or need HR as a stepping stone toward heavier combinations. The knowledge test is a multiple-choice assessment delivered at a VicRoads customer service centre, and it sits alongside the practical requirements for the class rather than replacing them.
The assessment samples the knowledge a HR driver needs before getting behind the wheel: how heavy vehicle licensing and vehicle categories work, what mass limits apply, how to do a proper pre-start inspection and recognise defects, how to restrain and secure a load, and how heavy vehicles must be braked, geared, cornered and spaced in traffic. It also covers general road rules, signage and sharing the road, plus fatigue management, work diary obligations and emergency procedures.
Preparation should be built on the current official Victorian heavy vehicle handbook or driver guide, read topic by topic, followed by practice questions and review of every wrong answer. Confirm current test details with VicRoads before booking.
What you'll study
About VIC Heavy Rigid Knowledge Test preparation
What is the format of the HR knowledge test?
It is a multiple-choice computer-based test taken at a VicRoads customer service centre. You select one answer per question from the options shown on screen. The exact number of questions and the time allowed are set by VicRoads and can change, so confirm them when you book rather than relying on older study material.
How hard is the test?
The road-rules content is familiar, but the heavy-vehicle material - mass limits, load restraint, pre-start defects, gearing and braking - is new to most car drivers and is where people lose marks. Treat it as a new subject rather than a repeat of the car learner test and work through every topic systematically.
What happens if I fail - can I retake it?
Yes, you can sit the test again, but the booking, waiting period and any fee are set by VicRoads and are not fixed here. Ask at the counter or check the VicRoads heavy vehicle licence page when you book. Before re-sitting, review the areas you missed instead of immediately retrying.
How long should I study before booking?
There is no official minimum, but most candidates need several weeks of regular study to cover all six topic areas properly. Read the current official handbook cover to cover, then work through practice questions until you are consistently answering heavy-vehicle topics correctly, not just the general road rules you already know.
What order should I study the topics in?
Start with licensing, vehicle categories and mass limits so the rest makes sense, then pre-start checks and defects, then load restraint. Move to driving technique - braking, gearing, cornering, following distance - before road rules and signage, and finish with fatigue management, work diaries and emergency procedures.
What are the most common failure points?
Load restraint principles, mass and dimension limits, identifying defects during a pre-start check, and fatigue and work diary rules trip up the most candidates. General road rules are usually well known. If you only skim the heavy-vehicle-specific topics, you are likely to fall short on the day.
Are the numbers and pass marks shown on this page official?
No. The permitted VicRoads source page could not be retrieved, so question counts, time limits, pass marks, fees and licence validity are deliberately left blank rather than guessed. Always confirm current figures on the official VicRoads heavy vehicle licence page before you book and pay.
Is passing the knowledge test enough to drive a heavy rigid vehicle?
No. The knowledge test is one requirement among several for the HR class, which also involves practical assessment and eligibility rules such as holding a qualifying lower-class licence for the required period. Check the current VicRoads requirements for the full sequence, including any medical or eyesight checks.
