- Q11Heavy vehicle
During a pre-trip brake check on an air-brake truck, the driver pumps the brake pedal and notices the air pressure gauge drops faster than normal. What does this indicate?
- AThere may be an air leak in the system that will reduce braking performance and must be investigated before driving
- BThe brakes are working correctly; rapid pressure drop confirms the service brakes are responsive
- CThe air compressor is too powerful and should be de-rated before the journey
- DThe pressure drop is normal for cold weather conditions; it will stabilise once the engine warms up

- Q12Heavy vehicle
What pre-trip check should be done on wheel nuts of a heavy vehicle?
- ASpray wheel nuts with lubricant to prevent them from seizing on long journeys
- BWheel nuts never need to be checked between full services; they are safety-locked at the factory
- CCheck visually and with a wheel-nut indicator or torque check that all nuts are present and correctly tightened
- DReplace every wheel nut at each pre-trip inspection as a precaution

- Q13Heavy vehicle
A driver notices during a pre-trip check that one of the rear dual tyres has zero pressure. The adjacent dual tyre appears normal. Is it safe to continue the journey?
- AYes, a dual tyre configuration is designed so one tyre in each pair can go flat without affecting safety
- BYes, if the journey is short and the speed is reduced below 60 km/h
- CYes, as long as the flat tyre is on the inside of the dual pair where it causes less steering effect
- DNo, the flat tyre must be changed or repaired before driving; the loaded tyre beside it will be dangerously overloaded and overheated

- Q14Heavy vehicle
What is the maximum continuous driving time for a heavy vehicle driver before a mandatory rest break must be taken? (Confirm current Bahrain rules with the General Directorate of Traffic.)
- ANo more than 4.5 hours of driving before taking a break of at least 45 minutes
- B8 hours of continuous driving before any rest is required
- C6 hours of driving followed by 30 minutes rest is acceptable under Bahrain rules
- DDriving hours are entirely at the discretion of the driver and employer in Bahrain

- Q15Heavy vehicle
Which of the following is an early warning sign of driver fatigue that a heavy vehicle driver should recognise and act on?
- AFeeling hungry and wanting to stop for a meal
- BFeeling warm due to the cab heater, which is a normal comfort response
- CFrequent blinking, difficulty focusing, missing road signs, and the vehicle drifting slightly within the lane
- DIncreased alertness and faster reaction times after more than 4 hours of driving
Answer and explanation in the bank
- Q16Heavy vehicle
A heavy truck driver has been on duty for 10 hours but only drove for 4 hours, spending the rest of the time loading and doing paperwork. Does duty time (non-driving work) contribute to fatigue that affects safe driving?
- ANo, only actual driving time causes fatigue; other work activities are restful by comparison
- BYes, all duty time, whether driving or other work, contributes to overall fatigue and reduces driving safety
- COnly physical tasks like loading count; administrative tasks are mentally stimulating and counteract fatigue
- DFatigue is only relevant after 6 hours of continuous driving regardless of other work
Answer and explanation in the bank
- Q17Heavy vehicle
A truck driver completing a night shift through Bahrain feels fine and is not sleepy. Research shows this is often misleading. Why?
- ADrivers on night shifts have adapted circadian rhythms that eliminate fatigue risk
- BNight driving is safer because there is less traffic and fatigue risk is lower than during the day
- CFeeling alert does not reliably predict fatigue level; research shows drivers often cannot accurately judge their own impairment and may experience sudden micro-sleeps without prior warning
- DCaffeine consumed at the start of the shift eliminates fatigue for the full night duration

- Q18Heavy vehicle
What is the driver's primary duty regarding passenger safety on a bus before moving off?
- AEnsure all passengers have bought a valid ticket before closing the doors
- BCheck that all passengers are seated or holding a handrail and doors are fully closed before moving
- CDrive slowly until passengers are seated; they are responsible for their own safety once aboard
- DSound the horn to warn standing passengers then move off at the timetabled time regardless

- Q19Heavy vehicle
A passenger on a bus suddenly collapses while the bus is moving. What should the bus driver do?

- CAsk another passenger to help and continue the route so the schedule is maintained
- DAccelerate to the nearest hospital and park on the pavement outside the emergency entrance
Answer and explanation in the bank

When should a bus driver refuse to allow a passenger to board?
- AWhen the bus is at full standing capacity and allowing more passengers would compromise safety
- BWhen the passenger does not have the exact fare
- CWhen the passenger is carrying luggage that slightly exceeds the baggage policy
- DWhen the driver is running behind schedule and every stop must be minimised

A truck carrying Class 3 flammable liquids is involved in a minor collision with no spillage. What is the driver's first priority?

- BCheck the load immediately by opening the tanker hatch to inspect for leaks
- CStop at a safe distance from the collision, warn other road users, contact emergency services, and report the incident as required for dangerous goods movements
