- Q11Heavy vehicle
Your loaded tanker has a total height of 4.5 metres. You approach a gantry sign showing 4.2 metres clearance. What is the correct action?
- AReduce tyre pressure to lower the vehicle height and proceed
- BProceed slowly; the 0.3-metre difference is within acceptable tolerance for road gantry measurements
- CStop before the gantry and find an alternative route; do not attempt to pass
- DDrive through in the centre of the lane to maximise headroom at the arch crown

- Q12Heavy vehicle
On a left-hand-drive truck operating in Bahrain (right-hand traffic), which side has the largest blind spot?
- AThe left side, because the driver sits on the left and cannot see directly to the left without leaning
- BThe right (passenger) side, because the driver is furthest from the right side of the cab
- CDirectly in front of the cab, behind the engine cover
- DBoth sides are equally blind because the cab is symmetrical

- Q13Heavy vehicle
Which mirror is most important for monitoring the right-side blind spot on a left-hand-drive truck in Bahrain?
- AThe interior rear-view mirror, which gives the widest angle of view to the rear
- BThe left-hand door mirror, because it is closest to the driver and easiest to read
- CNo mirror is needed on the right side because other road users must give way to trucks
- DThe right-hand wide-angle (convex) and flat wing mirror combination, adjusted to cover the right side as much as possible
Answer and explanation in the bank
- Q14Heavy vehicle
A cyclist is riding alongside the right side of your left-hand-drive truck at a junction. Why is this especially dangerous?
- ACyclists are not permitted on roads used by heavy trucks in Bahrain
- BCyclists always have right of way so the danger is minimal
- CThe right side is the largest blind zone for the driver, making it very difficult to see the cyclist before turning right
- DThe danger only exists at night when mirrors are hard to read
Answer and explanation in the bank
- Q15Heavy vehicle
You are about to move off from a roadside stop. Your mirrors are correctly adjusted. Which additional action is most important before pulling away to the right?
- ASound the horn continuously for 5 seconds to warn all nearby road users
- BCheck the left mirror only, because traffic in Bahrain passes on the left
- CNo additional check is needed if the mirrors are correctly set; trust the mirrors
- DCheck the right-side mirror and also turn your head to do a physical blind-spot check on the right before signalling and moving

- Q16Heavy vehicle
What is 'tail swing' on an articulated truck and when is it most likely to cause an accident?
- AThe tendency of the trailer to overtake the cab when the brakes are applied hard
- BThe swaying of a tanker body caused by liquid surge during braking
- CThe outward sweep of the rear of the trailer in the opposite direction to the turn when the driver steers
- DThe vibration of the cab caused by unbalanced rear tyres at high speed
Answer and explanation in the bank
- Q17Heavy vehicle
Why should the driver of a long articulated truck start a right turn from as far right in the lane as safely possible?
- ATo allow faster overtaking vehicles to pass on the left before the turn is complete
- BBahrain traffic rules require trucks to position to the right at all junctions regardless of turn direction
- CTo give the trailer the widest possible arc so it does not mount the kerb or strike objects on the inside of the turn
- DTo reduce tail swing, which only occurs when the vehicle starts the turn from the left
Answer and explanation in the bank
- Q18Heavy vehicle
You are driving an articulated truck and need to make a tight left turn. A motorcyclist is waiting at the junction on your left. What should you do?
- AComplete the turn quickly so the motorcyclist has minimal time in the danger zone
- BSound the horn and proceed; the motorcyclist should know to stay clear of trucks
- CWait for the motorcyclist to move fully out of your path, then complete the turn slowly while checking mirrors for the trailer's sweep through the turn
- DPull slightly right to signal your intent and proceed at normal turning speed

- Q19Heavy vehicle
What is meant by a high centre of gravity on a heavy vehicle and why does it matter?
- AIt means the engine is mounted high, which improves fuel economy on flat roads
- BIt refers to the height of the cab above the road surface, which affects driver visibility only
- CIt means the vehicle's mass is concentrated high above the ground, making it more likely to roll over when cornering or changing direction
- DIt describes the ideal suspension setting for carrying heavy loads on motorways
Answer and explanation in the bank
- Q20Heavy vehicle
A tanker carrying liquid is only half full. Why might this be more dangerous in terms of rollover than a full tanker?
- AA half-full tanker is always lighter so it has better handling in all conditions
- BA half-full tanker sits lower, reducing the centre of gravity and making it harder to see over obstacles
- CThe liquid insulates the tank walls, causing the tanker to overheat, which has no direct effect on rollover
- DThe free liquid surface can surge violently when the driver brakes or steers, creating unpredictable forces that can tip the vehicle

- Q21Heavy vehicle
You are approaching a roundabout at 50 km/h with a high-sided loaded trailer. What is the main risk?
- AThe trailer doors may open on the approach due to centrifugal force
- BThe trailer will jackknife because roundabouts require steering input in both directions
- CThe risk is no greater than for a car; modern truck suspension handles roundabouts safely
- DThe vehicle may roll over if the entry speed is too high, because lateral forces on a high centre of gravity can exceed the tipping limit of the tyres
Answer and explanation in the bank
- Q22Heavy vehicle
What does 'dynamic rollover threshold' mean for a heavily loaded tanker?
- AThe level of lateral acceleration at which the vehicle will start to tip onto its side, which is lower for high-centre-of-gravity vehicles
- BThe maximum speed at which the tanker can travel on a public road in Bahrain
- CThe point at which the trailer brakes engage automatically to prevent jackknifing
- DThe speed at which tyre grip is lost on a wet surface, measured in lateral G-force
