Six areas to understand before you test yourself

Do not memorise a list without understanding the reason behind it. A safe HR driver connects every check and decision to vehicle control, road-user safety and workplace procedure.

1

Know the vehicle and your authority to drive it

  • An HR class vehicle has at least three axles and a GVM above 8,000 kg.
  • Know the transmission fitted and any licence restriction that applies.
  • Follow current licence conditions, road rules, medical requirements and workplace procedures.
2

Complete a disciplined pre-start

  • Walk around the vehicle and check tyres, wheels, leaks, body, load, lights, mirrors and safety equipment.
  • Check fluids, controls, gauges, warning systems and the service and parking brakes.
  • Record and report defects. Do not take an unsafe vehicle onto the road.
3

Manage the size and weight of an HR vehicle

  • Leave more room, scan well ahead and use mirrors often.
  • Allow for blind spots, rear-wheel cut-in, a higher centre of gravity and longer stopping distances.
  • Select a suitable gear before a descent and use smooth steering, braking and acceleration.
4

Plan the route and secure the load

  • Confirm height, width, mass, access restrictions and bridge or structure clearances.
  • Use the correct restraint system, distribute the load properly and recheck it during the journey.
  • Check whether a Main Roads WA permit or order is required for a Restricted Access Vehicle.
5

Control hazards, fatigue and emergencies

  • Slow down early, increase space and drive to the conditions.
  • Treat yawning, poor concentration and slow reactions as warnings to stop safely and rest.
  • Know your workplace response for breakdowns, tyre or brake problems, load loss, crashes and fire.
6

Finish the job safely

  • Park where the vehicle will not obstruct traffic or create a hazard.
  • Stop, select neutral or park, apply the parking brake, shut down and remove the key.
  • Exit with three points of contact, secure the vehicle and complete required records.

20 original HR theory questions

Choose your answer before opening the explanation. Give yourself one point for each correct response.

Suggested target: 18/20

1. Which vehicle description fits the HR licence class in Western Australia?

  1. A rigid vehicle with two axles and any GVM
  2. A motor vehicle with at least three axles and a GVM above 8,000 kg
  3. Any prime mover towing a semi-trailer
  4. Any vehicle carrying more than eight passengers
Show answer

Answer: B. HR covers a motor vehicle with at least three axles and a GVM exceeding 8,000 kg. Licence restrictions and towing limits still matter.

2. During a walk-around you hear air escaping from a damaged brake hose. What is the safest response?

  1. Drive slowly and recheck it at the destination
  2. Cover the hose and begin the trip
  3. Keep the vehicle out of service and report the defect under workplace procedure
  4. Build maximum air pressure and ignore the leak if the warning light goes out
Show answer

Answer: C. A brake-system leak can make the vehicle unsafe. Record and report the defect, and do not drive until the vehicle has been cleared under the correct procedure.

3. Why should an HR driver begin braking earlier when using air brakes?

  1. Air brakes only work below 60 km/h
  2. There is a short delay while air pressure reaches and applies the brakes
  3. The parking brake must apply first
  4. The engine must be in neutral before the brakes operate
Show answer

Answer: B. Air takes time to travel through the system. That response delay, together with vehicle mass and road conditions, means the driver should plan ahead and allow more stopping room.

4. What is the best preparation before starting a long, steep descent?

  1. Select a suitable lower gear before the descent and use the approved auxiliary braking method
  2. Coast in neutral so the engine does not over-rev
  3. Wait until speed builds, then brake hard
  4. Change gears repeatedly while descending
Show answer

Answer: A. Set up the vehicle before going downhill. A suitable gear and approved auxiliary braking help control speed without relying entirely on the service brakes.

5. Why can the rear wheels of an HR vehicle strike a kerb during a turn even when the front clears it?

  1. The rear wheels follow a tighter path than the front wheels
  2. The steering locks after the front wheels turn
  3. The rear axle becomes wider under load
  4. The parking brake pulls the vehicle inward
Show answer

Answer: A. Rear-wheel cut-in means the back wheels track inside the front-wheel path. Check mirrors and allow enough space without creating a hazard for other road users.

6. Before moving into a lane while turning or merging, what should the driver do?

  1. Rely only on the indicator
  2. Check mirrors and blind areas, signal early and move only when there is safe space
  3. Sound the horn and move immediately
  4. Watch the front of the vehicle only
Show answer

Answer: B. An indicator communicates intention but does not create a gap. Scan mirrors and blind areas, then move smoothly only when the space is safe.

7. The view behind a loading bay is partly blocked. What is the safest reversing plan?

  1. Reverse quickly before another vehicle arrives
  2. Use the horn continuously and rely on the mirrors
  3. Get out and check the path, use a competent guide if available and reverse slowly
  4. Turn sharply so the cab faces the loading bay
Show answer

Answer: C. Confirm the path before moving. A guide can help with blind areas, but the driver remains responsible for keeping the manoeuvre slow and controlled.

8. A front tyre fails and the steering begins to vibrate. What should you do first?

  1. Brake as hard as possible
  2. Hold the steering firmly, ease off and avoid sudden braking while bringing the vehicle under control
  3. Turn sharply onto the shoulder
  4. Accelerate until the vibration stops
Show answer

Answer: B. Keep a firm, steady grip and avoid an abrupt brake or steering input. Slow progressively and stop in the safest available place under your emergency procedure.

9. Why should load restraints be rechecked during a journey?

  1. Movement and vibration can allow the load or restraint system to settle or loosen
  2. Restraints are only designed for the first hour of travel
  3. The vehicle becomes wider as fuel is used
  4. A recheck replaces the original loading inspection
Show answer

Answer: A. Road movement, braking and cornering can change how the load sits. Recheck it at appropriate safe opportunities and whenever workplace or load-restraint procedures require.

10. Your planned route includes a bridge with limited clearance. What should you do before departure?

  1. Assume a car navigation app will avoid it
  2. Measure or confirm the vehicle and load height, verify the route and choose a lawful alternative if needed
  3. Drive under it slowly while watching the roof
  4. Move to the centre of the road without checking traffic
Show answer

Answer: B. Route planning must account for the vehicle’s actual dimensions, mass and access conditions. General car navigation may not identify heavy-vehicle restrictions.

11. Where should a WA operator check whether an oversize or overmass movement needs a permit or order?

  1. The vehicle dealer
  2. Main Roads WA Heavy Vehicle Services
  3. The nearest fuel station
  4. The tyre manufacturer
Show answer

Answer: B. Main Roads WA manages permits, orders and access for Restricted Access Vehicles. Check the current requirements and operating conditions for the intended movement.

12. Heavy rain begins and visibility drops. Which response is most appropriate?

  1. Maintain speed so traffic does not build behind
  2. Reduce speed smoothly, increase the gap and use appropriate lights
  3. Use high beam in all conditions
  4. Follow another vehicle closely to see its tail lights
Show answer

Answer: B. Reduced grip and visibility need a lower speed, more space and smooth control inputs. Use lights suitable for the conditions and stop safely if continuing is not safe.

13. Another driver is following your HR vehicle too closely. What is the safest approach?

  1. Brake-check the other driver
  2. Speed up beyond the limit
  3. Increase the space ahead, avoid sudden changes and allow a safe opportunity for the other vehicle to pass
  4. Switch on the rear work lights
Show answer

Answer: C. More space ahead gives you room to slow progressively. Stay predictable and help the tailgater pass only when it can be done safely.

14. You are yawning, missing signs and struggling to concentrate. What should you do?

  1. Open a window and continue to the next delivery
  2. Drink an energy drink and increase speed
  3. Stop at a safe place and take the rest required by your fatigue plan and current rules
  4. Use the radio to stay awake
Show answer

Answer: C. These are fatigue warnings. Fresh air, music or caffeine do not replace adequate sleep and rest; stop safely and follow the applicable fatigue-management requirements.

15. An engine warning gauge moves outside its normal range and you notice unusual smoke. What is the best response?

  1. Ignore it if the vehicle still moves
  2. Apply full power to clear the engine
  3. Respond under the vehicle and workplace procedure, stop safely if required and report the fault
  4. Turn off all dashboard warnings
Show answer

Answer: C. Gauges, noise, vibration, leaks and smoke can warn of a developing fault. Acting early can prevent damage and reduce the risk of a breakdown or fire.

16. Which statement about communicating with other road users is correct?

  1. An indicator gives you right of way
  2. Signal early and clearly, but confirm the movement is safe before acting
  3. The horn should replace mirror checks
  4. Hazard lights should be used for every turn
Show answer

Answer: B. Signals help others understand your intention. They do not remove the need for observation, safe space and compliance with road rules.

17. Which sequence best describes a normal HR vehicle shutdown?

  1. Switch off while moving, apply the parking brake, then select neutral
  2. Stop, select neutral or park, apply the parking brake, shut down, remove the key and exit safely
  3. Stop, leave the engine running and lock the doors
  4. Apply the parking brake, jump from the cab and close the door
Show answer

Answer: B. Secure the stationary vehicle before leaving it. Check traffic, use the steps and grab handles, and maintain three points of contact when exiting.

18. A load appears to have shifted after heavy braking. What should the driver do?

  1. Continue at lower speed without checking it
  2. Stop at a safe place, inspect the load and have it made secure before continuing
  3. Turn sharply to move it back
  4. Remove one restraint so the load can settle
Show answer

Answer: B. A shifted load can change vehicle stability and may fall or move again. Stop safely and correct the load and restraint system before resuming the trip.

19. What does “three points of contact” mean when entering or leaving the cab?

  1. Two hands and one foot, or two feet and one hand, remain in contact with the vehicle
  2. Both feet land together while one hand holds the door
  3. The driver touches the tyre, step and mirror before climbing
  4. Three people must be present
Show answer

Answer: A. Use the steps and grab handles while facing the vehicle. Do not jump from the cab or use controls such as the steering wheel as a climbing handle.

20. How should a driver decide which PPE to wear during vehicle or load tasks?

  1. Wear the same items for every task, regardless of the hazard
  2. Follow the task risk, site rules and workplace procedure
  3. PPE is only required during the driving assessment
  4. Choose PPE based on the weather alone
Show answer

Answer: B. PPE must suit the hazards and the site or workplace requirement. Common examples include enclosed safety footwear, high-visibility clothing, gloves, eye protection, hearing protection and a hard hat where required.
