Practice mode· Heavy vehicle skillsDubai RTA - UAE Heavy Vehicle Skills Test 1
First set of questions on truck and bus operation: braking distances, load stability, blind spots, turning space and vehicle checks. Master the skills unique to heavy vehicles.
Why does a fully loaded heavy truck need a much greater stopping distance than a car travelling at the same speed?

- Q11Heavy vehicle
What is an engine brake (sometimes called a Jake brake or compression release brake) on a heavy vehicle?
- AAn emergency brake that activates automatically if the engine overheats
- BA device that locks the drivetrain to prevent the engine starting when the parking brake is off
- CA retarder system that uses engine compression or exhaust restriction to slow the vehicle without using the service brakes
- DA secondary braking system driven by the vehicle's electrical alternator

- Q12Heavy vehicle
When approaching a long, steep descent in a heavy vehicle, what should you do before starting the downgrade?
- ASelect an appropriate low gear before the descent so engine braking assists speed control throughout the hill
- BShift to neutral to save fuel and control speed with the service brakes as needed
- CIncrease speed before the crest so you can coast to the bottom and minimise brake use
- DSwitch off the engine brake and rely solely on the service brakes for simplicity

- Q13Heavy vehicle
Why is it dangerous to shift into neutral (or disengage the clutch) when descending a long steep hill in a heavy vehicle?
- AShifting to neutral causes the transmission to lock up, making steering very heavy
- BIt causes air system pressure to drop rapidly, releasing the parking brake
- CIt removes all engine braking, so the vehicle accelerates freely under gravity and the driver must rely entirely on service brakes, risking brake fade
- DNeutral is perfectly safe on descents because the transmission still provides resistance

- Q14Heavy vehicle
You are driving a fully laden articulated truck down a steep mountain road. Your speed is creeping upward despite light brake applications. What is the correct immediate action?
- ASwitch the engine off to use maximum compression resistance
- BSelect a lower gear, activate the engine brake, and apply the service brakes firmly but briefly to reduce speed before the situation worsens
- CSteer toward the uphill bank and use it to slow the vehicle
- DAccelerate briefly so the engine governor automatically limits your speed

- Q15Heavy vehicle
What is the purpose of under-run protection bars (rear and side guards) fitted to heavy vehicles?
- ATo strengthen the chassis so it can carry heavier loads over rough ground
- BTo mark the outer edges of the vehicle visually for other road users at night
- CTo prevent cars and motorcycles from sliding under the vehicle body in a collision, which could cause decapitation or catastrophic crush injuries
- DTo provide a step platform for loading crew to access the cargo area safely

- Q16Heavy vehicle
Why must cargo on a flatbed truck be properly secured before the journey begins?
- ASecuring is only required when the journey is over 100 km
- BCargo securing is optional if the goods are not classified as hazardous
- CCargo only needs to be secured when travelling on motorways
- DUnsecured cargo can shift under braking or cornering, altering the vehicle's balance and potentially falling onto other road users
Answer and explanation in the bank
- Q17Heavy vehicle
How does an improperly distributed load affect an articulated truck when cornering?
- AA load concentrated too high or to one side raises the centre of gravity and greatly increases rollover risk on bends
- BLoad position has no effect on cornering because modern air suspension self-levels the vehicle
- CA rear-heavy load improves cornering by adding downforce on the drive axles
- DUneven loading only matters on unpaved or off-road surfaces
Answer and explanation in the bank
- Q18Heavy vehicle
Where should the heaviest items be placed within a truck load to promote vehicle stability?
- ALow down and centred over the axles
- BAt the very rear of the load to add weight over the drive axles
- CAs high as possible for easy access during delivery
- DPosition does not matter as long as total weight is within legal limits
Answer and explanation in the bank
- Q19Heavy vehicle
How often should a driver check cargo security during a long journey?
- AOnly at the start and end of the journey
- BNever, if the load was correctly secured at the beginning
- CAt regular intervals during the journey, especially shortly after departure, because loads settle and lashings loosen over time
- DOnly when the driver notices a change in how the vehicle handles
Answer and explanation in the bank
- Q20Heavy vehicle
A load falls from a truck onto a motorway and causes an accident. Who bears primary responsibility under UAE traffic law?
- AThe loading crew only, because the driver did not personally load the vehicle
- BThe vehicle owner only, not the driver
- CNo one is liable if the total load was within the legal weight limit
- DThe driver, who is responsible for ensuring the load is secure before and during every journey
Answer and explanation in the bank
- Q21Heavy vehicle
What does Gross Vehicle Weight (GVW) mean?
- AThe weight of the vehicle when it is completely empty
- BThe total weight of the cargo only, excluding the vehicle itself
- CThe weight distributed on the rear axles alone
- DThe maximum total permitted weight of the vehicle including the vehicle itself, its cargo, fuel, and any passengers
Answer and explanation in the bank
- Q22Heavy vehicle
What is the main danger of overloading a truck axle?
- AIt only causes the speedometer to read inaccurately
- BThe engine will automatically shut down if an axle is overloaded
- COverloading an axle improves traction and grip
- DIt can cause tyre blowouts, brake overheating, loss of steering, and structural damage to both the road and the vehicle
