NZ Heavy Vehicle Theory Test study plan
NZ Heavy Vehicle Theory Test · Give each week a clear focus.
8 weeks · About 6 hours per week
Heavy vehicle licence classes and what you can drive
Map every NZ heavy vehicle licence class (Class 2, 3, 4, 5) to the vehicle combinations and gross weights each one legally allows you to drive.
Explain the difference between a Class 1 licence with a heavy trailer endorsement and a full Class 2, and state which one a light rigid truck plus heavy trailer requires.
Identify the towing and trailer weight thresholds that push a vehicle combination into a higher licence class.
List the conditions attached to a Class 2 licence, including the requirement for a certificate of fitness and a road user charges account.
Define gross vehicle mass, gross combined mass and tare weight, and calculate each from a simple vehicle specification sheet.
Your checkpoint
A one-page licence class reference table with vehicle types, weight limits and one worked GVM/GCM calculation, scored at least 9/10 on a self-made recall quiz.
Heavy vehicle licence classes and what you can drive & Heavy vehicle safety and inspection requirements (certificate of fitness, vehicle equipment)
Match each licence class to the certificate of fitness requirements that apply to that vehicle type, including inspection frequency.
Explain what a certificate of fitness certifies and how it differs from a warrant of fitness.
Describe the process for renewing a certificate of fitness and what happens if it expires while the vehicle is in service.
Identify the vehicle equipment items checked during a certificate of fitness inspection, such as brakes, lights, tyres, load security and glazing.
State the driver's responsibility for ensuring the certificate of fitness is current before operating the vehicle.
Your checkpoint
A completed certificate of fitness checklist covering at least 12 inspection items, each with the pass criteria and the driver action if it fails.
Heavy vehicle safety and inspection requirements (certificate of fitness, vehicle equipment)
Explain the heavy vehicle braking requirements, including the role of a brake performance test and when it is needed.
Identify the lighting and reflector requirements for heavy vehicles, including clearance lamps and rear marker boards.
Describe tyre legal requirements for heavy vehicles, including minimum tread depth, load rating and the rules on mixing tyre types.
Explain load security obligations, including the use of lashings, rated tie-down points and the consequences of an insecure load.
Outline the daily pre-trip walk-around inspection a driver must perform and the defects that must be reported before driving.
Your checkpoint
A written pre-trip inspection routine of at least 15 checks in sequence, plus a defect reporting example, reviewed against the official vehicle inspection requirements.
Driving a truck or heavy vehicle safely
Explain how a heavy vehicle's mass and centre of gravity affect stopping distance and cornering stability.
Describe safe following distances for a loaded truck at 50, 80 and 90 km/h, and justify the gap using reaction time plus braking distance.
Identify the main blind spots around a heavy vehicle and the mirror checks needed before changing lanes or turning left.
Explain the risks of rollover on corners and roundabouts, and the speed and load factors that increase them.
Describe how to manage a heavy vehicle on a steep descent, including gear selection and the use of engine braking rather than continuous service braking.
Your checkpoint
A stopping-distance and following-gap calculation sheet for three speeds, plus a written left-turn blind spot procedure with at least six steps.
Driving a truck or heavy vehicle safely & General road code and safe driving habits
Apply the give way rules at intersections, including the left-turn rule and uncontrolled intersections, to heavy vehicle scenarios.
Explain the rules for passing stationary school buses, emergency vehicles and road workers, and how vehicle size affects the safe response.
Describe the correct action at a railway level crossing, including the requirement to stop, look and listen for heavy vehicles.
Identify the licence demerit point thresholds and the consequences of accumulating demerit points on a heavy vehicle licence.
Explain the fatigue management obligations for heavy vehicle drivers, including maximum work periods and minimum rest breaks.
Your checkpoint
A 20-question self-test on give way rules and fatigue limits, with every wrong answer rewritten as a corrected rule statement.
Road user charges and heavy vehicle operation
Explain what road user charges are, which vehicles pay them and why light diesel vehicles and all heavy vehicles are charged by distance.
Describe how a road user charges licence works, including the requirement to purchase distance before travel and the offence of running without a current licence.
Explain the role of the hubodometer and how distance is recorded and verified.
Identify the consequences of an inaccurate odometer or hubodometer reading, including back-dated charges and penalties.
Describe how vehicle weight and axle configuration affect the road user charges rate for a heavy vehicle.
Your checkpoint
A worked example calculating road user charges for a 4-axle truck travelling 1,200 km in a month, with the licence purchase and record-keeping steps listed.
Road user charges and heavy vehicle operation & General road code and safe driving habits
Explain the operator responsibilities that sit alongside road user charges, including record keeping and the requirement to produce records on request.
Describe the overweight and dimension limits that apply to heavy vehicles and how exceeding them affects road user charges and permits.
Apply general road code rules on speed limits, no-overtaking lines and following distances to heavy vehicle situations.
Explain the rules for parking and loading on the roadside, including the use of warning devices and hazard lights.
Describe how alcohol, drugs and prescription medication affect driving fitness and the legal limits that apply.
Your checkpoint
A completed case study of an overweight load: the permit or exemption needed, the road user charges adjustment, and the legal risks, written in under 400 words.
Heavy vehicle licence classes and what you can drive & Driving a truck or heavy vehicle safely & Heavy vehicle safety and inspection requirements (certificate of fitness, vehicle equipment) & Road user charges and heavy vehicle operation & General road code and safe driving habits
Complete a full-length practice test under timed conditions and score at least 85 percent overall.
Review every missed question and classify it by domain, then re-study the two weakest domains.
Recite the licence class limits, certificate of fitness frequency and road user charges rules from memory without notes.
Explain the pre-trip inspection and the left-turn blind spot procedure aloud in under five minutes each.
Confirm the test-day logistics, including identification requirements and the pass mark for the theory test.
Your checkpoint
Two timed full-length practice tests with a written error log, showing an improvement of at least 10 percentage points between the first and second attempt.
Milestones
Week 2: Can state the vehicle combinations and weight limits for every heavy vehicle licence class from memory, and explain the difference between a certificate of fitness and a warrant of fitness.
Week 4: Scores at least 80 percent on a 30-question mixed test covering licence classes and certificate of fitness, and can list 15 pre-trip inspection items without notes.
Week 6: Can calculate road user charges for a given vehicle and distance unaided, and scores at least 80 percent on a 20-question test on heavy vehicle handling and fatigue rules.
Week 8: Scores at least 85 percent on two consecutive timed full-length practice tests, with no single domain below 70 percent.
