Practice mode· Heavy vehicle skillsCapital General Directorate of Traffic - Bahrain 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.
Compared with a car travelling at the same speed, a fully loaded heavy truck will generally need a stopping distance that is:

- Q11Heavy vehicle
You are about to descend a long gradient and notice the 'Trucks: engage low gear' sign. What is the correct action?
- AApply the service brakes firmly now and shift to a higher gear for better engine braking
- BShift to neutral to save fuel and apply brakes as needed throughout the descent
- CReduce speed and shift to a low gear before the descent begins, using engine braking to control speed on the way down
- DThe sign applies only to vehicles over 40 tonnes; continue in the current gear

- Q12Heavy vehicle
Which situation poses the greatest risk of jackknifing on an articulated truck fitted with air brakes?
- AHard braking on a slippery surface causing the drive axles to lock while the trailer continues forward
- BApplying full brake pressure gently on a dry straight road
- CEngaging the exhaust brake on a flat road at low speed
- DReleasing the brakes gradually after a complete stop on a hill

- Q13Heavy vehicle
When securing cargo on a flatbed truck, what is the minimum requirement for load security?
- AThe load must be covered with a tarpaulin; straps are optional if the load is heavy enough
- BA single ratchet strap across the middle of the load is sufficient for loads under 5 tonnes
- CLoad security is the responsibility of the loading company, not the driver
- DThe load must be prevented from moving in any direction and must not project dangerously or fall onto the road
Answer and explanation in the bank
- Q14Heavy vehicle
Where should the heaviest part of a cargo be positioned on a truck to optimise vehicle stability?
- AAs high as possible to keep the load away from the chassis floor
- BLow and centred over the axles to lower the centre of gravity and distribute weight evenly
- CAt the rear of the trailer to improve steering feel at the front axle
- DTowards the right side of the load bed to compensate for the driver's weight on the left
Answer and explanation in the bank
- Q15Heavy vehicle
During a journey you notice your truck is pulling to one side even though the road is straight and level. What could this indicate about the load?
- AThe load is correctly distributed and the symptom is caused by road camber
- BThe load has shifted to one side, causing an uneven weight distribution that affects steering and tyre loading
- COne of the steering axle tyres is over-inflated, which is unrelated to load distribution
- DThe front axle weight is too low, meaning more cargo should be moved forward
Answer and explanation in the bank
- Q16Heavy vehicle
A load projects more than 1 metre beyond the rear of your truck. What is required in Bahrain? (Confirm exact distances with the General Directorate of Traffic.)
- ANo special measures are needed as long as the overall vehicle length is under 22 metres
- BThe load must be refused; projection beyond the bodywork is never permitted on Bahrain roads
- CThe projection must be marked with a red flag or light and may require a special permit depending on the length
- DOnly a rear reflective marker plate is needed, regardless of how far the load projects
Answer and explanation in the bank
- Q17Heavy vehicle
What does 'gross vehicle weight' (GVW) mean?
- AThe weight of the vehicle alone with all fluids but no cargo or passengers
- BThe maximum combined weight of the vehicle, its cargo, fuel, driver, and any passengers as specified by the manufacturer and regulator
- CThe weight recorded at the last annual vehicle inspection
- DThe weight of the cargo only, excluding the vehicle's own mass
Answer and explanation in the bank
- Q18Heavy vehicle
Your laden truck is approaching a bridge with a posted weight limit of 30 tonnes but your gross vehicle weight is 32 tonnes. What must you do?
- ADo not cross. Find an alternative route or obtain a special crossing permit from the authorities before proceeding
- BCross at low speed; the weight limit has a built-in safety margin that covers 2 extra tonnes
- CDeflate the tyres slightly to reduce the load on the bridge deck
- DCross quickly so the dynamic weight on the structure is lower than the static limit
Answer and explanation in the bank
- Q19Heavy 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
- Q20Heavy 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
Answer and explanation in the bank
- Q21Heavy 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
- Q22Heavy 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
