VIC Heavy Rigid Knowledge Test study guide
VIC Heavy Rigid Knowledge Test · Work through your exam, one topic at a time.
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 VIC Heavy Rigid Knowledge Test study guide has 6 sections and about 2,856 words.
01Heavy Vehicle Licensing: Classes, Scope and Obligations
Victorian heavy vehicle classes are cumulative and are defined by axle count and gross vehicle mass. Light rigid (LR) covers a rigid vehicle from 4.5 to 8 tonnes GVM and may tow a trailer up to 9 tonnes GVM.
354 words, about 2 min02Pre-start checks, vehicle inspection and defects
Tare mass is the empty vehicle. GVM is the manufacturer's maximum loaded mass of the vehicle itself.
751 words, about 4 min03Inspection, Defects and Reporting
A minor defect is one that does not make the vehicle unsafe to drive but must be fixed soon - a blown marker lamp, a worn wiper blade, a cracked mirror. A major defect affects safety or emissions and grounds the vehicle until it is repaired: faulty brakes, a broken spring, a cracked wheel, steering play, a leaking air line, an insecure load.
361 words, about 2 min04Load Restraint and Load Security
A load restraint system must be able to withstand the forces of heavy braking, acceleration and cornering without the load shifting. The accepted figures are: 0.8 g forward , 0.5 g rearward and 0.5 g sideways , measured against the weight of the load.
349 words, about 2 min05Fatigue management, work diaries and emergency procedures
Heavy vehicles run air brakes, which have a noticeable lag between pedal and response, and stopping distance grows sharply with mass. Brake early, brake smoothly, and leave room.
700 words, about 4 min06Road Rules, Signage and Sharing the Road Safely
Heavy vehicles are limited to 100 km/h and may be governed lower. On multi-lane roads with a speed limit over 80 km/h, heavy vehicles must keep out of the right-hand lane unless overtaking or turning.
