- Q11Heavy vehicle
What is the function of the fifth wheel on an articulated truck?
- AIt is a spare wheel mounted under the chassis for use in a tyre blowout
- BIt is an additional steering axle fitted behind the drive axle to aid tight turns
- CIt is the air-pressure governor that limits maximum brake force on the trailer
- DIt is the coupling plate on the tractor that connects to and supports the kingpin of the semi-trailer, allowing it to pivot

- Q12Heavy vehicle
What checks must a driver carry out after coupling a semi-trailer to the tractor unit?
- ACheck the tyre pressures on the trailer and adjust the fifth wheel height only
- BDrive forward slowly to feel whether the coupling is firm, then proceed to load
- CConfirm the trailer registration number matches the permit and then depart
- DConfirm the kingpin is locked in the fifth wheel, check all air and electrical lines are connected, and test trailer brakes before moving

- Q13Heavy vehicle
When uncoupling a semi-trailer on uneven ground, what is the greatest safety risk?
- AThe tractor moving forward and damaging the fifth wheel plate
- BThe air lines disconnecting and releasing the parking brakes on the tractor
- CThe kingpin jamming and preventing future coupling with a different tractor
- DThe trailer rolling away or toppling over once it is no longer supported by the tractor, especially if the landing legs are not fully extended on a slope

- Q14Heavy vehicle
What is the purpose of a split (range) gearbox on a heavy truck?
- AIt allows the truck to switch between front-wheel drive and rear-wheel drive depending on road conditions
- BIt doubles the number of available gear ratios, allowing the driver to match engine speed precisely to road speed and load conditions
- CIt provides a secondary braking system when the main air brakes overheat
- DIt divides engine torque equally between the drive axles to prevent wheel spin

- Q15Heavy vehicle
Before beginning a journey, what tyre checks must a heavy-vehicle driver carry out?
- ACheck only that the tyres are visually round and continue if no obvious flat is visible
- BCheck the inner drive axle tyres only, as outer tyres are less important
- CTyre checks are the responsibility of the fleet maintenance team and not the driver
- DCheck tyre pressure (including spare), inspect for cuts, bulges, foreign objects, and check that tread depth meets legal minimums on all wheels

- Q16Heavy vehicle
How does extreme desert heat in Oman affect truck tyres during a long journey?
- AHeat softens the tyre rubber, increasing grip and allowing higher safe speeds
- BHeat has no effect on properly inflated tyres; only underinflation causes problems
- CHeat causes the air inside the tyre to expand, raising pressure beyond safe limits and increasing the risk of a blowout
- DHeat reduces tyre pressure, so drivers should add air during the journey

- Q17Heavy vehicle
What pre-trip brake check should a driver perform on a truck fitted with air brakes before each journey?
- ABuild air pressure to the correct level, test that the low-pressure warning activates at the correct threshold, check for air leaks, and test the parking and service brakes
- BPress the brake pedal once firmly to check it is not soft, then depart if the pedal returns
- CAir brake checks are only required after the vehicle has been serviced by a mechanic
- DCheck the brake fluid reservoir level and top up if below the minimum mark

- DThe driver's view of the road is blocked by passengers standing near the cab
