- Q11Heavy vehicle
Which of the following is a likely consequence of overloading a drive axle on a heavy truck?
- ABetter traction on loose surfaces due to increased tyre contact
- BIncreased tyre wear, potential tyre failure, reduced braking performance, and possible prosecution for exceeding axle weight limits
- COverheating of the differential only, with no effect on brakes or tyres
- DReduced fuel consumption because the engine load is more evenly distributed
Answer and explanation in the bank
- Q12Heavy vehicle
A truck and trailer combination is stopped at a Bahrain weigh station. The front steer axle reads 8 tonnes, the drive tandem reads 19 tonnes, and the trailer tandem reads 17 tonnes. The posted steer-axle limit is 7 tonnes. What is the best immediate action?
- AArgue that the reading is within instrument error and proceed
- BShift cargo forward to balance the trailer axle
- CAccept the overload violation, pay any fine, then shift cargo rearward to reduce steer-axle loading before continuing
- DContinue driving because the gross combination weight is within overall limits

- Q13Heavy vehicle
What must a heavy vehicle driver check before driving under a low bridge or height restriction gantry?
- AThe overall height of the vehicle and any load, confirming it is less than the posted clearance
- BOnly the cab height, since the cab is always the tallest part of the vehicle
- CThe width of the road under the bridge, not the vertical clearance
- DNothing; gantry restrictions apply only to double-decker buses, not trucks
Answer and explanation in the bank
- Q14Heavy vehicle
What is the recommended approach if a heavy truck driver is unsure whether a route has sufficient clearance for the vehicle's width?
- ADrive through slowly and rely on the vehicle's wing mirrors to judge clearance
- BPlan the route in advance using maps and transport authority guidance, and obtain a wide-load permit if the vehicle exceeds the standard width limit
- CThe width of a truck never requires a permit in Bahrain as long as it is within the manufacturer's specification
- DAsk the passenger to guide from outside the vehicle while driving through narrow sections
Answer and explanation in the bank
- Q15Heavy 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
Answer and explanation in the bank
- Q16Heavy 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
Answer and explanation in the bank
- Q17Heavy 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
- Q18Heavy 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
- Q19Heavy 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
Answer and explanation in the bank
- Q20Heavy 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
- Q21Heavy 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
- Q22Heavy 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
