Always confirm the current requirements with your driving school or the traffic department.

Q: Is this practice test free?

Yes. It is completely free, with no signup or payment, and you can retake it as many times as you like.

Q: What does the Hawalli truck & bus theory test cover?

Road signs, traffic signals, right of way, roundabouts, speed limits, seat belts, penalties and safe-driving rules, plus the handling and safety topics specific to your vehicle.

Question 1

A heavy truck driver approaches a school zone with a posted limit of 40 km/h. Does this limit apply to the truck?

Accepted Answer

Yes. All speed limits apply to heavy vehicles, and the truck must not exceed 40 km/h in that zone. Speed limits apply to all vehicles including heavy trucks. A 40 km/h school zone limit must be observed by every driver. In many cases heavy vehicles face an additional lower limit in built-up areas, making compliance even more important.

Answer

No. Speed limits for schools apply only to cars and minibuses

Answer

Only if school is in session at the time of passing

Answer

Only if the truck is carrying passengers

Question 2

During a pre-trip inspection, you press the brake pedal and the air pressure gauge drops rapidly and does not recover. What does this indicate?

Accepted Answer

A significant air leak in the braking system that must be repaired before the vehicle is driven. A rapid, unrecovered pressure drop after brake application indicates an air leak. Air brakes rely on adequate pressure to release the spring-loaded parking brakes and to apply the service brakes. Operating a vehicle with a significant air leak is extremely dangerous and the fault must be repaired before departure.

Answer

Normal behaviour; air pressure always drops when the brakes are applied

Answer

The air dryer needs to be recharged with refrigerant

Answer

The spring brakes need to be manually reset

Question 3

What is the minimum air pressure a truck's air brake system should show before driving away? (Confirm the exact specification with the manufacturer and the General Traffic Department.)

Accepted Answer

Typically at least 6 to 7 bar (approximately 90 psi) before the low-pressure warning light extinguishes and the vehicle is safe to move. Air brake systems have a low-pressure warning light or buzzer that activates below a threshold (commonly around 4 to 5 bar). The vehicle should not be moved until the system has built sufficient pressure - typically 6 to 7 bar or higher as specified by the manufacturer. Confirm limits with the vehicle's manual and the General Traffic Department.

Answer

Any positive reading on the gauge is acceptable

Answer

Exactly 2 bar; higher pressure causes brake fade

Answer

The gauge does not matter as long as the spring brakes release

Question 4

In hot Kuwaiti desert conditions, why should a truck driver check tyre pressures more frequently than in temperate climates?

Accepted Answer

Heat causes the air inside tyres to expand, increasing pressure, and pavement heat can accelerate casing breakdown leading to blowout. High ambient temperatures and hot road surfaces in Kuwait significantly increase tyre temperatures. As air heats it expands, raising pressure beyond safe limits. Overheated tyres are also more prone to structural failure and blowout. Pressures should be checked when tyres are cold and the vehicle should not be driven on underinflated tyres in heat.

Answer

Desert sand enters the valve stems and reduces pressure over time

Answer

Low humidity dries out the rubber and makes it contract, reducing pressure

Answer

Hot weather has no significant effect on tyre pressure

Question 5

During a desert crossing in summer, a driver notices a rear tyre is visibly bulging. What is the correct action?

Accepted Answer

Stop safely off the road, do not deflate the tyre, and arrange for a tyre technician to inspect and change it. A bulging tyre indicates internal structural damage (a casing separation or belt failure) and is on the verge of a blowout. The driver must stop immediately and safely, keep clear of the tyre, and arrange for a proper tyre change. Releasing air or continuing to drive risks a catastrophic blowout.

Answer

Release air from the tyre to reduce pressure, then continue to the destination

Answer

Drive slowly to the nearest workshop, as the tyre will hold for short distances

Answer

Increase speed briefly so air movement cools the tyre

Question 6

A truck driver has been driving continuously for many hours. Which of the following is an early warning sign of fatigue that should prompt an immediate rest stop?

Accepted Answer

Difficulty keeping eyes open, missing road signs, and micro-sleeps of a few seconds. Early fatigue signs include heavy eyelids, yawning frequently, drifting out of lane, and missing road signs or junctions. Micro-sleeps - brief unconscious episodes lasting 1 to 4 seconds - are extremely dangerous. At highway speed a vehicle can travel over 100 metres during a 4-second micro-sleep. Drivers must stop and rest as soon as fatigue is noticed.

Answer

Feeling slightly hungry and thinking about the next meal

Answer

Noticing oncoming headlights on a dark road

Answer

Reduced cabin temperature from the air conditioning

Question 7

What is the maximum number of continuous driving hours recommended before a heavy vehicle driver must take a rest break? (Confirm current Kuwait regulations with the General Traffic Department.)

Accepted Answer

Generally no more than 4 to 4.5 hours, after which a break of at least 30 to 45 minutes is required. International best practice and GCC guidelines recommend no more than 4 to 4.5 hours of continuous driving before taking a substantial rest break. Fatigue impairs reaction time as significantly as alcohol. Drivers should confirm the precise hours-of-service limits with the General Traffic Department as Kuwait may specify its own requirements.

Answer

10 hours continuous driving is permitted as long as the driver feels alert

Answer

There is no legal limit; the driver decides when to rest

Answer

A 5-minute break every 3 hours is sufficient

Question 8

A bus driver must ensure passenger safety before moving away from a stop. Which action is most important?

Accepted Answer

Confirm all doors are fully closed and no passenger is still boarding or alighting. The bus driver must not move until all doors are closed and no passenger is caught in or near the doors. Driving with a door open or before a passenger has finished boarding or alighting can cause serious injury or death. The driver should also check all mirrors before pulling away.

Answer

Sound the horn twice to warn passengers to sit down

Answer

Check the right-side mirror only, as passengers always board from the right

Answer

Move off slowly and rely on passengers to hold the handrails

Question 9

A passenger bus is involved in an emergency and must be evacuated quickly. Where are emergency exits most commonly located?

Accepted Answer

At the rear of the bus and in the roof (roof hatch), in addition to the main entrance doors. Buses are required to have emergency exits beyond the main service doors. These typically include a rear emergency door and one or more roof hatches, allowing passengers to escape even if the main doors are blocked. Bus drivers must know the location and operation of all emergency exits.

Answer

Only at the front next to the driver

Answer

Buses do not have emergency exits; passengers use the main door only

Answer

Under the seats as floor hatches

Question 10

When transporting standing passengers on a bus, what does the driver need to be particularly careful about during braking?

Accepted Answer

Braking gradually and progressively so standing passengers have time to brace rather than being thrown forward violently. Standing passengers have no seatbelt and less stability. Sudden or harsh braking can throw them forward causing serious injuries. Bus drivers must brake progressively and anticipate stops early, applying smooth deceleration to protect standing passengers.

Answer

Using only the handbrake so the bus stops more gently

Answer

Braking hard to stop as quickly as possible to reduce the time passengers are standing

Answer

Standing passengers are not affected by braking because the aisle is clear

Question 11

A truck is carrying dangerous goods (hazardous materials). At a petrol station where the driver wants to refuel, what rule applies?

Accepted Answer

The vehicle must be parked away from fuelling areas, engine off, and the driver must follow site safety rules; many dangerous goods loads prohibit refuelling at public stations. Vehicles carrying hazardous materials face strict restrictions at fuel stations. The engine must be off, smoking is forbidden, and drivers must follow site regulations. Some dangerous goods classifications prohibit use of public filling stations entirely. The driver must be trained in the specific requirements for the goods being carried.

Answer

Refuelling is permitted normally as long as the engine is running for safety

Answer

Only the trailer must be disconnected before refuelling

Answer

Dangerous goods vehicles may refuel at any time with no special precautions

Question 12

What information must be displayed on a vehicle carrying dangerous goods to alert emergency services in case of an accident?

Accepted Answer

Orange hazard identification plates (Kemler code panels) showing the hazard code and UN number of the substance. Dangerous goods vehicles must display standardised hazard warning panels. The orange panels show the Kemler hazard identification number (top) and the UN substance number (bottom), enabling emergency services to immediately identify the material and apply correct procedures. Placards must be properly displayed front, rear, and sides as required.

Answer

A yellow flashing beacon on the roof only

Answer

The company name and phone number on the side of the truck

Answer

A red flag at the front and rear of the vehicle

Question 13

What qualification must a driver possess to legally transport dangerous goods in Kuwait?

Accepted Answer

A dangerous goods transport licence or certificate approved by the relevant Kuwaiti authority, in addition to the standard heavy vehicle licence. Transporting dangerous goods requires specialised training and an approved dangerous goods certificate in addition to the standard heavy vehicle driving licence. The training covers safe handling, emergency response, and documentation. Confirm the specific Kuwaiti requirements with the General Traffic Department.

Answer

Only a heavy vehicle licence is required; no additional certification is needed

Answer

A first aid certificate is the only additional requirement

Answer

Any licensed driver with three years of experience may transport any dangerous goods

Question 14

A truck fitted with a split (range) gearbox approaches a motorway. When should the driver shift from the low range to the high range?

Accepted Answer

After reaching a speed where the top gear of the low range is no longer efficient, typically when the engine reaches a mid-to-high speed in the highest low-range gear. A split gearbox doubles the number of ratios by providing a high and low range. The driver starts in low range for acceleration and shifting up. When the top of the low range is reached and engine speed is appropriate, the driver switches to high range and works back up through the gears. This gives finer ratio control for efficient operation at all speeds and loads.

Answer

At the start of every journey regardless of speed

Answer

Only when carrying a full load

Answer

High range should be used from engine start to avoid damage

Question 15

You are driving a fully loaded truck on a flat road at 80 km/h and a child runs into the road 60 m ahead. Why is your stopping distance much greater than a car driver would expect?

Accepted Answer

The combination of heavy mass, longer reaction-to-braking delay, and the need for air brake build-up all add to a significantly longer stopping distance. A fully loaded heavy truck may weigh 40 tonnes or more. The momentum at 80 km/h is enormous, and air brakes also require a fraction of a second to build pressure. Together, reaction time and brake application time can add many metres to stopping distance compared with a car. Maintaining a large following distance is essential.

Answer

Trucks have smaller tyres that grip less effectively

Answer

The automatic transmission slows the braking response

Answer

Trucks are only affected by stopping distance on wet roads

Question 16

You are following another truck on the motorway. What is the recommended minimum following distance for a heavy vehicle at 90 km/h?

Accepted Answer

At least a 2-second gap, but many guidelines recommend 3 to 4 seconds for heavy vehicles at motorway speeds, especially when loaded. Heavy vehicles need longer following distances due to greater mass and longer braking distances. A 2-second gap is the minimum for cars; loaded trucks should maintain at least 3 to 4 seconds. This gives time to perceive a hazard, apply brakes, and allow the air system to build pressure. Confirm requirements with the General Traffic Department.

Answer

One truck length (approximately 12 m) regardless of speed

Answer

The same gap as a car, 2 seconds, since braking systems are equivalent

Answer

No minimum gap is specified for heavy vehicles on motorways

Question 17

During a pre-trip walk-around inspection, what should a driver check on each tyre?

Accepted Answer

Pressure, tread depth, sidewall condition (no cuts, bulges, or damage), and that all wheel nuts are secure. Every tyre on every axle must be checked before departure. This includes pressure with a calibrated gauge, tread depth, sidewall integrity (no bulges or cuts), and that wheel nuts are tight. A defective or improperly inflated tyre on a heavy vehicle can cause blowout or loss of control at speed.

Answer

Only that the tyre is inflated - exact pressure is not important on heavy vehicles

Answer

Only the two rear drive tyres, as the front tyres rarely develop problems

Answer

Tyre colour to ensure they match the fleet standard

Question 18

Which item is NOT typically checked during a heavy vehicle pre-trip brake inspection?

Accepted Answer

The colour of the brake fluid reservoir cap. A pre-trip brake inspection covers air pressure, warning devices, parking brake function, and brake adjustment. The colour of the reservoir cap is not a functional check. Drivers must follow a systematic checklist covering all safety-critical systems before operating the vehicle.

Answer

Air pressure build-up time from low pressure to operating pressure

Answer

Function of the low air pressure warning light or buzzer

Answer

Operation of the spring (parking) brakes

Question 19

The air pressure warning light illuminates while you are driving a loaded truck on the motorway. What should you do immediately?

Accepted Answer

Pull off the road safely as soon as possible, apply the parking brake, and do not continue until the fault is diagnosed and repaired. The air pressure warning signals that system pressure has dropped to a dangerous level. If pressure continues to fall, the spring brakes will automatically engage. The driver must stop safely immediately, apply the parking brake manually, and not move the vehicle until the air system fault is repaired.

Answer

Continue to the nearest town (10 km away) driving slowly

Answer

Pump the brake pedal to rebuild pressure in the system

Answer

Switch off the engine and wait 10 minutes for pressure to rebuild

Question 20

What is the difference between a service brake failure and a spring brake application in an air brake system?

Accepted Answer

Service brakes are applied by air pressure; spring brakes (parking brakes) are held off by air pressure and apply automatically when air pressure is lost. Air brake systems use two principles. Service brakes are activated by adding air pressure when the driver presses the pedal. Spring brakes are normally held in the released position by air pressure; when pressure drops below a threshold (system fault or parking), the heavy spring forces the brake on automatically. This is a fail-safe design ensuring the vehicle stops if the air supply is lost.

Answer

Spring brakes are applied by the driver's foot; service brakes apply automatically when speed exceeds a limit

Answer

Both types are identical; the name just depends on which axle they are fitted to

Answer

Service brakes work on the trailer; spring brakes work on the tractor only

Question 21

You are about to drive a high-sided curtainsider trailer across a raised bridge in strong wind conditions. What is the main risk?

Accepted Answer

The wind acting on the large flat side of the trailer can create a force strong enough to push the vehicle sideways, potentially causing loss of control or rollover. A high-sided trailer presents an enormous surface area to crosswinds. On exposed areas such as bridges, the wind force can be sudden and severe. The driver must reduce speed, maintain a firm grip on the steering wheel, and be prepared for the vehicle to move sideways. Wind warnings should be taken seriously before using exposed routes.

Answer

The bridge surface will be slippery due to wind-driven sand

Answer

The wind reduces tyre pressure significantly on the exposed side

Answer

High-sided vehicles create a wind shadow that benefits following vehicles

Question 22

What should a driver do when overtaking a high-sided vehicle in strong crosswinds?

Accepted Answer

Be prepared for a sudden gust or change in wind when moving out from behind the shelter of the large vehicle, which can push the overtaking vehicle sideways. A large vehicle temporarily shelters the vehicle behind it from crosswinds. When the overtaking vehicle clears the front of the large vehicle, it is suddenly exposed to the full force of the wind. This can cause an abrupt steering correction requirement. The driver must anticipate this and maintain firm steering control.

Answer

Overtake quickly at high speed to minimise exposure to the wind

Answer

The slipstream of the large vehicle makes overtaking easier in crosswinds

Answer

There is no additional risk when overtaking a large vehicle in wind
