- Q11Heavy vehicle
What is the minimum legal tread depth for heavy vehicle tyres in Oman?
- AApproximately 1 mm across the central three-quarters of the tread width
- BNo legal minimum exists for truck tyres; drivers judge condition visually
- C5 mm is required for all vehicles including cars and trucks
- DTread depth does not matter for truck tyres because they use rib-pattern tyres with no directional grooves

- Q12Heavy vehicle
What is the main reason that dual (twin) rear tyres on a truck drive axle must be checked for pressure on both inner and outer tyres?
- AInner tyres always inflate to a higher pressure than outer tyres due to heat transfer
- BAn underinflated inner tyre is hidden from view and carries most of the load when the outer tyre is normal, causing it to fail without warning
- CThe tyre pressure monitoring system only monitors outer tyres, so inner tyres must be checked manually
- DInner and outer tyres must be matched within 5 kg/cm squared of each other for ABS to function correctly

- Q13Heavy vehicle
A driver notices that their loaded truck's steering wheel has become unusually heavy when turning. What is the most likely cause?
- AThe front axle is overloaded, compressing the front suspension and increasing steering resistance
- BSelecting a low gear on a straight road causes a mechanical feedback in the steering column
- CCold ambient temperature thickening the steering fluid; it will improve once the vehicle warms up
- DA power steering fluid leak or pump failure, reducing or eliminating power assistance

- Q14Heavy vehicle
Why must a bus driver carry out a passenger count before departing from a terminal?
- ATo calculate the fuel needed for the journey based on total weight
- BTo confirm all tickets have been scanned before departure
- CTo ensure the number of passengers does not exceed the vehicle's licensed seating capacity and to comply with safety and insurance regulations
- DTo report passenger numbers to the Royal Oman Police before every intercity journey

What action must a bus driver take before opening doors at a bus stop in Oman?
- ASound the horn to warn pedestrians that the doors are about to open
- BEnsure the bus is fully stationary, check mirrors for cyclists or motorcyclists passing on the right, and only then open the doors
- COpen doors while still slowing to save time, as this is standard practice at busy stops
- DFlash the hazard lights twice to signal to traffic behind that doors are opening

- Q16Heavy vehicle
An empty high-sided curtainsider trailer is being driven back to the depot. Why can an unladen truck sometimes be more difficult to control than the same truck when loaded?
- AThe empty trailer causes the fifth wheel to overheat, creating a steering wobble at speed
- BWithout load weight, the transmission can select too high a gear automatically, causing the engine to lug
- CAn empty truck has a lower centre of gravity, making it more prone to understeer in corners
- DThe lighter mass reduces tyre-road grip, reduces the effectiveness of the brakes in preventing wheel lock, and increases wind sensitivity; the suspension may also bounce more severely

- Q17Heavy vehicle
What does the term 'swept path' mean when a truck driver plans a tight manoeuvre?
- AThe total area of road surface used by all wheels of the vehicle (including trailer) as it completes the manoeuvre, from the widest tracking of the cab to the tightest inside tracking of the rear wheels
- BThe path taken by the cab front alone when turning, used to judge the minimum turning circle
- CThe distance the vehicle travels from the start of braking to the point of stopping
- DThe arc described by the trailer when reversing at a specific steering angle

- Q18Heavy vehicle
A truck driver on a long Oman highway journey notices that the outside temperature has risen to 45 degrees Celsius and the engine temperature gauge is approaching the red zone. What should the driver do?
- APull off the road safely, switch off the engine, and wait for the engine to cool before checking the coolant level; do not open the radiator cap while the engine is hot
- BTurn the heater on full blast to draw heat away from the engine and continue driving
- CRev the engine higher to circulate coolant faster and reduce temperature
- DOpen the bonnet while driving to allow air to cool the engine as quickly as possible

- Q19Heavy vehicle
What is brake fade and when is it most likely to occur on a heavy vehicle?
- AAir leaking from the brake chambers, most likely in cold weather
- BA reduction in braking power caused by overheated brake drums or discs, most likely on long descents
- CA gradual increase in brake pedal travel caused by worn brake shoes
- DThe ABS cutting in repeatedly on a wet road

- Q20Heavy vehicle
When descending a steep mountain pass such as the Jebel Akhdar road in a loaded truck, what is the correct technique to control speed?
- ASelect a low gear before the descent and use the engine or exhaust brake as the primary speed control, applying service brakes briefly and sparingly if needed
- BSelect a high gear to reduce engine braking and use the service brakes continuously to maintain a steady speed
- CDisengage the clutch and coast in neutral, braking gently to keep the speed constant
- DSelect the highest gear available to keep engine speed low and reduce fuel consumption

- Q21Heavy vehicle
What is an exhaust brake (also called a Jake brake or engine retarder) used for on a heavy truck?
- ATo increase engine power when climbing steep hills with a heavy load
- BTo slow the vehicle using engine compression resistance, reducing reliance on the service brakes during descents
- CTo lock the rear wheels for controlled emergency stops
- DTo release the parking brake automatically when the driver selects a drive gear

- Q22Heavy vehicle
A truck's air brake system shows a low air pressure warning. What should the driver do?
- AContinue driving slowly at low speed until the air compressor rebuilds pressure
- BStop safely as soon as possible and not move the vehicle until the fault is found and repaired
- CSwitch to the secondary hydraulic brake circuit and continue the journey
- DApply the parking brake and drive on, as it will compensate for reduced air pressure
