- ASound the horn continuously while reversing to warn anyone in the path
- BReverse as quickly as possible to minimise the time the truck is in a vulnerable position

- Q13Heavy vehicle
What is the maximum permitted speed for a heavy truck on a Saudi dual carriageway (expressway) outside urban areas?
- A120 km/h, the same as for private cars
- B150 km/h on motorways with no speed camera enforcement
- CSpeed limits do not apply to heavy trucks licensed for long-distance haulage
- DThe limit posted for heavy vehicles on that road, which is often lower than the limit for cars
Answer and explanation in the bank
- Q14Heavy vehicle
In urban areas in Saudi Arabia, what speed limit typically applies to heavy trucks where no other sign is posted?
- A80 km/h, because heavy trucks need to keep up with traffic
- B100 km/h on all roads with three or more lanes
- CThere is no urban speed limit for heavy trucks
- D50 km/h, unless a sign shows a different limit
Answer and explanation in the bank
- Q15Heavy vehicle
A heavy truck is equipped with a speed limiter. The limiter is set to 90 km/h. A traffic sign shows a 110 km/h limit. What must the driver do?
- AComply with the lower of the two limits, which is the 90 km/h speed limiter setting; the vehicle must not exceed the limiter regardless of the posted limit
- BOverride the speed limiter because posted road signs always take priority over vehicle settings
- CDrive at 110 km/h only on multi-lane roads where overtaking lanes are available
- DRemove the speed limiter fuse temporarily and drive at the posted speed

- Q16Heavy vehicle
Which tyre check is most important during a pre-trip inspection of a heavy truck in Saudi Arabia's hot climate?
- ACheck tyre pressure when cold, inspect for cuts, bulges, uneven wear, and embedded objects, and check that all wheel nuts are properly torqued
- BOnly check that tyres appear inflated visually; precise pressure measurement is needed only at service intervals
- CInflate tyres to the maximum sidewall pressure rating before each trip to compensate for heat expansion
- DCheck tread depth only; pressure and sidewall condition are secondary concerns
Answer and explanation in the bank
- Q17Heavy vehicle
During a pre-trip brake check on a truck with air brakes, the driver builds pressure to maximum, turns off the engine, and observes the gauges. If the pressure drops more than approximately 10 psi in one minute, what does this indicate?
- AThere is a significant air leak in the braking system that must be located and repaired before the vehicle is driven
- BThe air dryer is working correctly and removing moisture from the system
- CThe pressure drop is normal and the vehicle is safe to drive
- DThe spring brakes need adjusting at the next scheduled service
Answer and explanation in the bank
- Q18Heavy vehicle
What should a heavy truck driver check regarding lights and reflectors during a pre-trip inspection?
- AOnly the headlamps and brake lights need checking; marker lights are optional on trailers
- BLights only need checking at night or in bad weather
- CAll headlamps, indicators, brake lights, reverse lights, and reflective markers on the vehicle and trailer must be clean, undamaged, and functioning
- DOnly lights visible from the front of the vehicle are required by law
Answer and explanation in the bank
- Q19Heavy vehicle
A driver carries out a pre-trip inspection and finds that one of the dual rear tyres is flat while its twin appears correctly inflated. What action must be taken?
- ADrive carefully to the nearest tyre workshop at reduced speed, as the good tyre can handle the load for short distances
- BInflate the flat tyre to double the normal pressure to compensate, then drive to the next stop
- CReplace or repair the flat tyre before moving the vehicle; operating on a single tyre in a dual fitment overloads the remaining tyre and can cause its sudden failure at speed
- DIt is acceptable to drive on a single tyre in a dual fitment as long as the vehicle is not fully loaded
Answer and explanation in the bank
- Q20Heavy vehicle
Saudi Arabia requires heavy truck and bus drivers to observe mandatory rest periods to prevent fatigue. What is the general principle regarding continuous driving time before a rest break?
- ADrivers must stop and rest at regular intervals during long trips and never drive while tired
- BDrivers may drive continuously for 24 hours as long as they feel alert
- CRest breaks are only required for night driving
