- Q11Heavy vehicle
What does the width of a heavy vehicle include for the purposes of compliance with width limits?
- AThe widest point of the vehicle or load, including mirrors, any projecting equipment, and the load itself
- BThe body of the vehicle only, not mirrors or protruding equipment
- COnly the cab width, as the trailer is measured separately
- DWidth limits do not apply to vehicles over 20 tonnes
Answer and explanation in the bank
- Q12Heavy vehicle
A load projects more than 1 metre beyond the rear of the truck. What must the driver do? (Confirm the exact requirements with the General Traffic Department.)
- AFit a warning marker such as a red flag or marker board at the rear of the projecting load, and may require a special permit depending on the projection length
- BDrive only at night when other vehicles can see the projection with headlights
- CNo action is needed as long as the projection is less than 2 metres
- DTravel in the right lane only to keep the projection away from other traffic

- Q13Heavy vehicle
Which is the correct technique for braking on a wet road in a loaded truck equipped with ABS?
- AApply firm, steady pressure to the brake pedal and allow the ABS to modulate the brakes; do not pump the pedal
- BPump the brake pedal rapidly to prevent wheel lock
- CUse only the engine brake and avoid the service brakes completely
- DApply the trailer hand valve first, then the service brake

- Q14Heavy vehicle
What is the risk of a fully loaded truck taking a motorway exit ramp at the speed recommended for a car?
- AA truck is heavier so it corners more safely at that speed
- BThere is no additional risk as long as the tyres are correctly inflated
- CThe posted ramp speed is designed for cars; a loaded truck has a much higher centre of gravity and could roll over at the same speed
- DThe risk only exists for articulated trucks, not rigid trucks

- Q15Heavy vehicle
The fifth wheel on the tractor has not been lubricated. What is the most likely consequence during operation?
- AThe trailer will automatically disconnect at the first corner
- BExcessive wear on the fifth wheel plate and kingpin, difficult steering around tight turns, and possible cracking of the mounting
- CFuel consumption will improve because friction is reduced
- DThe air supply lines will be damaged by the dry friction

- Q16Heavy vehicle
Before a long trip, a driver finds one side of the truck is noticeably lower than the other due to an asymmetric load. What is the correct action?
- ARe-distribute the load evenly before departure to balance the vehicle and bring all axle weights within legal limits
- BInflate the tyres on the lower side to compensate for the extra weight
- CDrive carefully and lean to the opposite side to compensate
- DThe truck will self-correct once it reaches speed on the motorway

- Q17Heavy vehicle
A truck has a maximum gross vehicle weight of 40 tonnes. The tare (unladen) weight is 15 tonnes. What is the maximum payload the driver may legally carry?
- A25 tonnes, calculated as GVW minus tare weight
- B40 tonnes, because GVW is the total weight of the load only
- C15 tonnes, which is the same as the tare weight by regulation
- DThere is no payload limit as long as the driver drives carefully

- Q18Heavy vehicle
A tipper truck is unloading on uneven ground. The rear body is raised. What rollover risk must the driver consider?
- AThe raised body acts as a sail and is only dangerous in high winds
- BThe risk is limited to fully loaded tippers; a partially loaded raised body is safe on any ground
- CThe raised body shifts the centre of gravity upward and backward; even a small sideways lean of the chassis can cause the vehicle to tip over
- DThe rear outriggers automatically deploy to prevent rollover during tipping
Answer and explanation in the bank
- Q19Heavy vehicle
Which of the following correctly describes the purpose of a speed limiter fitted to a commercial heavy vehicle?
- AIt is a device that prevents the engine from propelling the vehicle above a set maximum speed regardless of accelerator position
- BIt is a device that automatically applies the brakes if the speed limit is exceeded
- CIt alerts the driver with a warning light when exceeding the speed limit
- DIt limits engine revolutions to save fuel only, with no effect on top speed
Answer and explanation in the bank
- Q20Heavy vehicle
On a long descent, the driver uses the exhaust brake to maintain speed. The exhaust brake is most effective in which gear?
- AThe highest gear, to keep engine speed low and reduce wear
- BNeutral, to allow the exhaust brake to work independently of the drivetrain
- CA lower gear, because lower gears produce higher engine revolutions, generating more braking force through the exhaust system
- DExhaust brake effectiveness does not vary with gear selection
Answer and explanation in the bank
- Q21Heavy vehicle
What does 'axle overloading' mean and why is it dangerous?
- AIt means the vehicle is travelling over an axle count restriction on a bridge
- BIt means the axle grease has overheated and needs replacing
- CIt means one or more axles carry weight beyond their rated capacity, stressing tyres, wheel bearings, suspension, and the road surface, and increasing the risk of component failure
- DIt means all axles are equally loaded, which reduces tyre wear

- Q22Heavy vehicle
A driver is reversing a long articulated truck into a loading bay. The trailer begins to 'jackknife' (fold at the coupling). What is the correct corrective action?
- AStop, then pull forward to straighten the combination before attempting the reverse again with smaller steering corrections
- BTurn the steering wheel further in the same direction to accelerate the swing
- CApply maximum lock in the opposite direction to the jackknife while continuing to reverse at speed
- DApply only the trailer brakes to stop the trailer swinging
