Read them all. The answer and the reason for each, and the timed 22-question run, are in the RAK Traffic Theory Test Questions PDF.
- Q11Heavy vehicle
How should a heavy-vehicle driver approach a roundabout to reduce the risk of rollover?
- AMaintain motorway speed and brake sharply at the give-way line
- BAccelerate through the roundabout to minimise time spent turning
- CSlow down well before the roundabout and enter at a speed that keeps the vehicle stable throughout the full arc of the turn
- DUse the handbrake to control speed on the roundabout itself

- Q12Heavy vehicle
A heavy vehicle is carrying bulk liquid in a partially filled tanker. Why is this particularly hazardous on bends?
- ALiquid loads cause the brakes to vibrate and lose effectiveness
- BThe liquid surges sideways (free surface effect), raising the effective centre of gravity and greatly increasing rollover risk
- CA partial fill reduces tyre grip on the inside wheels of the bend
- DA partly filled tanker is always lighter and therefore inherently safer than a full one
Answer and explanation in the bank
- Q13Heavy vehicle
Which of the following best explains why a loaded high-sided truck rolls over at a lower cornering speed than the same truck when unladen?
- AA loaded truck has higher tyre pressure, which reduces tyre grip on bends
- BEngine power increases with load, causing the driver to over-accelerate into bends
- CA loaded truck has stiffer suspension that transfers excessive force directly to the tyres
- DThe load raises the centre of gravity, so less lateral force is needed to tip the vehicle past its stability threshold

- Q14Heavy vehicle
What is the fifth wheel on a tractor unit?
- AThe spare wheel stored under the tractor chassis
- BAn additional tag axle fitted between the drive axles
- CThe horseshoe-shaped coupling plate mounted on the tractor that the trailer kingpin locks into, connecting tractor to trailer
- DA steering-assistance mechanism on the front axle
Answer and explanation in the bank
- Q15Heavy vehicle
After coupling a trailer to a tractor, how should a driver verify the connection is secure?
- APull gently forward against the trailer brakes and visually confirm the kingpin lock is engaged and the safety latch is in place
- BDrive on the road for 10 km to let the coupling settle before checking
- CRev the engine hard; if the trailer does not move the coupling is secure
- DThe coupling mechanism self-checks and no driver inspection is needed
Answer and explanation in the bank
- Q16Heavy vehicle
When uncoupling a trailer on a flat surface, what must the driver complete before releasing the kingpin?
- AApply the trailer parking brake, lower the landing legs to take the weight, and disconnect air and electrical lines
- BRelease the kingpin first, then apply the trailer brakes and lower the legs
- CLeave the trailer brakes off so the trailer can be repositioned by hand later
- DOnly the landing legs need to be lowered; the brakes and lines can be dealt with afterwards
Answer and explanation in the bank
- Q17Heavy vehicle
What is the kingpin on a semi-trailer?
- AThe heavy steel pin fixed to the underside of the trailer's front that locks into the tractor's fifth wheel to join the two units
- BThe main retaining bolt holding the trailer's rear axle assembly
- CThe pin connecting the trailer landing leg to the chassis frame
- DA pivot pin on the front steerable axle of a self-steering trailer

- Q18Heavy vehicle
When should a banksman (spotter) be used to assist a heavy-vehicle driver who is reversing?
- AOnly when reversing on public roads after dark
- BOnly when the vehicle is carrying dangerous goods
- CA banksman is legally required only for vehicles longer than 20 metres
- DWhenever the driver cannot clearly see all areas behind the vehicle, especially in confined yards or busy areas
Answer and explanation in the bank
- Q19Heavy vehicle
What is the standard signal a banksman uses to tell a reversing heavy-vehicle driver to stop immediately?
- ABoth arms raised or crossed clearly above the head, or a raised fist held prominently
- BOne hand pointing to the left side
- CBoth hands waving downward toward the ground
- DOne finger pointing at the ground directly behind the vehicle
Answer and explanation in the bank
- Q20Heavy vehicle
You are reversing a truck with a banksman guiding you. You suddenly lose sight of the banksman in your mirrors. What must you do?
- AContinue slowly because the banksman will reappear in your mirrors shortly
- BStop immediately and do not move again until visual contact with the banksman is re-established
- CSound the horn and continue at the same cautious speed
- DAsk a passenger in the cab to lean out and look for the banksman while you continue
Answer and explanation in the bank
- Q21Heavy vehicle
Are the speed limits for heavy vehicles on UAE highways generally the same as, lower than, or higher than those posted for private cars?
- AExactly the same as posted limits for all vehicle types
- BLower: heavy vehicles have their own, lower limits shown on signs, and many must be fitted with speed limiters
- CHigher, because trucks are engineered for sustained high-speed operation
- DThere are no separate speed limits for heavy vehicles
Answer and explanation in the bank
- Q22Heavy vehicle
Why are separate, lower speed limits set for heavy vehicles on UAE roads?
- AHeavy vehicles are less aerodynamic and physically cannot safely reach the speeds cars can reach
- BLower limits are set purely to reduce the fuel consumption of commercial fleets
- CMuch longer stopping distances and higher rollover risk mean a crash at the same speed as a car causes far greater damage and injury
- DSeparate limits make it easier for police to issue fines to commercial operators
