Always confirm the current requirements with your driving school or the traffic department (for example via the Metrash2 service).

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 Umm Salal 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

What do continuous white centre-line markings on a Qatar road indicate?

Accepted Answer

You must not cross or straddle the line. A continuous (solid) white centre line means you must not cross or straddle it. It indicates a section of road where overtaking or changing lanes across the line is dangerous or prohibited.

Answer

You may cross only to overtake

Answer

Advisory lane divider only, crossing is permitted

Answer

Pedestrian crossing zone

Question 2

What is the general rule for following distance between your vehicle and the one in front on a Qatar road?

Accepted Answer

Maintain a safe gap that allows you to stop if the vehicle ahead brakes suddenly. A safe following distance gives you the reaction and braking time needed if the vehicle ahead stops suddenly. Tailgating is one of the leading causes of rear-end crashes. For specific minimum distances, confirm with the General Directorate of Traffic.

Answer

Keep at least one car length for every 10 km/h of speed

Answer

Stay within two metres so other drivers cannot cut in

Answer

Following distance only matters on motorways, not urban roads

Question 3

You are leaving a highway via an off-ramp (exit slip road) and a vehicle on the highway signals to exit behind you. Who has priority on the slip road?

Accepted Answer

The vehicle ahead on the slip road (you), as you are already committed to the exit. On an exit slip road, vehicles already on the ramp have priority. The vehicle joining the ramp from the highway must ensure adequate spacing and should not force its way in front of a vehicle already committed to the exit. Confirm with the General Directorate of Traffic.

Answer

The vehicle on the highway, because it is on the main carriageway

Answer

Both vehicles must stop and negotiate

Answer

The faster vehicle

Question 4

When is it safe to overtake another vehicle on a single-carriageway road?

Accepted Answer

Only when there is a clear and sufficient gap ahead, you have good visibility, and it is legal to do so. Safe overtaking requires checking that overtaking is permitted (no solid centre line or prohibition signs), that you have a sufficient gap to complete the manoeuvre and return to the left before any oncoming traffic arrives, and that there are no junctions, pedestrians, or hazards ahead. An insufficient gap or poor visibility makes overtaking extremely dangerous.

Answer

Whenever the vehicle ahead is travelling below the speed limit

Answer

On approach to a bend if the road ahead appears clear

Answer

Any time the road ahead is empty for at least 100 metres

Question 5

What is the consequence of driving in Qatar without valid third-party motor insurance?

Accepted Answer

A fine and possible vehicle impoundment. Liability for any accident damages falls entirely on the uninsured driver.. Motor insurance is compulsory in Qatar. Driving without valid insurance exposes the driver to fines and vehicle impoundment, and leaves them personally liable for all costs arising from any accident. The exact fine can change, so confirm current amounts with the General Directorate of Traffic via Metrash2.

Answer

Only a verbal warning for a first offence.

Answer

No penalty if no accident occurs during the uninsured period.

Answer

Insurance is optional in Qatar for vehicles less than three years old.

Question 6

What is the correct pre-trip tyre inspection procedure for a heavy vehicle driver?

Accepted Answer

Check tyre pressure when cold, inspect for cuts, bulges, foreign objects, and confirm minimum legal tread depth on all tyres including the spare. Cold inflation pressure is the only accurate measure, as heat from driving artificially inflates readings. A visual and physical inspection must cover all tyres, including the spare. Cuts, bulges, or embedded objects indicate structural damage that could cause a blowout. Minimum tread depth must meet legal requirements; confirm the current minimum with the General Directorate of Traffic.

Answer

Kick each tyre once; if it feels solid the pressure is adequate

Answer

Check only the drive axle tyres as they carry the most load

Answer

Check tyre pressure only after driving 20 km, when tyres have reached operating temperature

Question 7

What do broken white lane markings on a road indicate?

Accepted Answer

Lane changes are permitted when safe. Broken (dashed) white lines between lanes indicate that you may change lanes when it is safe to do so. Always check mirrors and blind spots before moving.

Answer

No lane changes allowed

Answer

Pedestrian crossing ahead

Answer

End of the road

Question 8

The two-second rule for following distance means that after the vehicle ahead passes a fixed point, you should reach that point in no less than how many seconds?

Accepted Answer

Two seconds under dry conditions, more in adverse conditions. The two-second rule is a simple way to estimate a safe gap in dry conditions: count two seconds between the vehicle ahead passing a fixed reference and you reaching it. In rain, dust, or at night you should at least double this gap. Confirm current official guidance with the General Directorate of Traffic.

Answer

One second

Answer

Five seconds at all times

Answer

Ten seconds on motorways only

Question 9

You are at a Y-junction where your road splits into two. You want to take the right fork. Is there a right-of-way issue?

Accepted Answer

Usually no, because a Y-junction fork is a diverge, not a merge; however, follow any signs present. At a Y-junction where the road simply splits (diverges), there is typically no right-of-way conflict because traffic is separating. Right-of-way rules apply when roads merge or cross. Always obey any signs present. Confirm with the General Directorate of Traffic.

Answer

You must always stop before taking either fork at a Y-junction

Answer

Vehicles going left always have priority at a Y-junction

Answer

Y-junctions are not covered by Qatar traffic rules

Question 10

What minimum gap should you ensure is available ahead before beginning to overtake a car on an open road at high speed?

Accepted Answer

A gap large enough to complete the overtake and return to lane with a safety margin on both sides. At high speeds, closing distances are large. You need to judge that the available gap is enough for acceleration time plus the overtaking distance plus a safety buffer before any oncoming vehicle or hazard arrives. In practice this can require several hundred metres of clear road. When in doubt, do not overtake. Confirm with the General Directorate of Traffic.

Answer

Exactly 50 metres of clear road is always sufficient

Answer

The same as the gap required when following in normal traffic

Answer

Any gap is acceptable if you accelerate quickly enough

Question 11

A resident of Qatar has held a Qatari driving licence but it has expired for three months. They continue to drive daily. What is the likely legal outcome?

Accepted Answer

Driving on an expired licence is illegal and can result in fines, black points and vehicle impoundment.. A driving licence in Qatar must be renewed before it expires. Driving on an expired licence is treated as driving without a valid licence, which is a serious offence. Penalties can include fines, black points and vehicle impoundment. Always renew your licence on time. Confirm penalty amounts with the General Directorate of Traffic via Metrash2.

Answer

An expired licence carries no penalty if it was valid at the time it was originally issued.

Answer

There is a 12-month grace period after expiry during which driving remains legal.

Answer

The only consequence is that the licence cannot be renewed for a year.

Question 12

How does Qatar's intense summer heat affect heavy vehicle tyres, and what precaution should drivers take?

Accepted Answer

Heat increases tyre pressure and accelerates degradation of the rubber; drivers should check pressure when cold and avoid over-inflation. In Qatar's summer temperatures exceeding 45 degrees Celsius, ambient heat plus the heat generated by the tyre's own flexing can raise internal pressure significantly. An already over-inflated tyre can reach dangerous pressure levels leading to blowout. Always set tyre pressure to the manufacturer's cold specification and never deflate a hot tyre to compensate for pressure rise.

Answer

Heat softens the rubber and improves grip, so higher pressures can be used safely

Answer

Desert heat has no significant effect on tyres designed for commercial use

Answer

Over-inflated tyres perform better in summer because the sidewalls are stiffer

Question 13

What does a blue rectangular sign generally indicate in Qatar?

Accepted Answer

Informational or directional guidance, such as motorway directions or facilities. Blue rectangular (or square) signs are used for information and mandatory instructions. In Qatar, blue signs include motorway route markers, service information and certain mandatory direction signs. Green signs are also used for major route information.

Answer

A prohibition

Answer

A warning of a hazard ahead

Answer

An end-of-restriction sign

Question 14

Who must wear a seat belt in a private car travelling in Qatar?

Accepted Answer

The driver and all passengers in every seat. Qatar traffic regulations require the driver and all passengers to wear seat belts at all times. Seat belts save lives in collisions by preventing occupants from being thrown against the interior or ejected from the vehicle.

Answer

Only the driver

Answer

The driver and front-seat passenger only

Answer

Adults only; children under 12 are exempt

Question 15

On a one-way street, an emergency vehicle comes from behind with lights and sirens. What should you do?

Accepted Answer

Move as far to one side as possible and stop to allow the emergency vehicle to pass. Emergency vehicles have right of way everywhere, including on one-way streets. Move to one side and stop when it is safe. Do not drive in reverse to clear the way as this creates additional hazards. Confirm with the General Directorate of Traffic.

Answer

Speed up and turn off the one-way street at the next junction

Answer

Drive in reverse to create space

Answer

Continue at the same speed; emergency vehicles must follow traffic rules on one-way streets

Question 16

What is the correct way to set your seat position for safe driving?

Accepted Answer

Sit upright with a slight bend in the arms at the wheel and feet able to press pedals fully. A correct seating position gives full pedal travel, comfortable steering control with arms slightly bent, and an unobstructed view of all mirrors. A reclined seat reduces reaction speed because you cannot apply full brake force quickly, and it positions you incorrectly relative to the airbag and seatbelt anchor points.

Answer

Recline the seat as far back as possible for comfort on long journeys

Answer

Sit as far forward as possible so you can see over the bonnet

Answer

Seat position only matters for taller drivers; shorter drivers can adapt

Question 17

What does 'reckless driving' mean under Qatar's traffic law?

Accepted Answer

Operating a vehicle in a way that puts other road users at risk, showing disregard for safety rules.. Reckless driving in Qatar covers a broad range of behaviour that endangers other road users, such as extreme speeding, aggressive manoeuvres, ignoring traffic signals and similar acts showing wilful disregard for road safety. It carries severe penalties including heavy fines, imprisonment and possible vehicle confiscation.

Answer

Driving above 100 km/h on any road.

Answer

Changing lanes without signalling once.

Answer

Driving with a tyre pressure 5% below the manufacturer's recommendation.

Question 18

A heavy vehicle driver notices the tread on the inside shoulder of both rear tyres is wearing much faster than the outside. What is the most likely cause?

Accepted Answer

Incorrect wheel alignment or the axle is out of square, causing the tyres to scrub inward. Uneven tread wear on the inside shoulder of both rear tyres is a classic sign of toe misalignment or a bent axle. The tyres are effectively scrubbing sideways as they roll, which destroys tread rapidly and increases fuel consumption. The vehicle must be taken off the road for a wheel alignment check before tyre failure occurs.

Answer

The vehicle is consistently under-loaded on the rear axle

Answer

The tyres are running at too high a pressure for the road surface

Answer

Inside shoulder wear is normal for dual rear tyres and requires no action

Question 19

When does the No Overtaking restriction indicated by a sign end?

Accepted Answer

When you see an end-of-no-overtaking sign or an end-of-all-restrictions sign. A No Overtaking restriction stays in force until you see the specific end-of-no-overtaking sign (two cars with a black diagonal cancelling the earlier sign) or an end-of-all-restrictions sign. A speed-limit sign only changes the speed limit and does not lift an overtaking ban. Do not assume the restriction has ended without the correct sign.

Answer

After exactly 1 kilometre

Answer

When the road ahead becomes straight

Answer

When you see a new speed-limit sign

Question 20

At what age are children in Qatar generally required to use an appropriate child restraint seat rather than just a seat belt?

Accepted Answer

Children who have not yet reached the height and weight thresholds for adult belts. Child restraint rules are based on a child's height and weight, not age alone. An adult seat belt alone cannot protect a small child properly in a crash. Always confirm the current specific thresholds with the General Directorate of Traffic and use an approved restraint system.

Answer

Under 10 years old

Answer

Under 4 years old only

Answer

Children are never required to use a child seat if they can buckle themselves in

Question 21

Two vehicles reach a STOP-controlled intersection at exactly the same time from different roads. Both have come to a full stop. What happens next?

Accepted Answer

The vehicle on the right has priority to proceed first. When two vehicles arrive simultaneously at a STOP sign intersection, the standard tie-breaking rule is to give way to the vehicle on the right. This mirrors the unmarked junction rule. Confirm with the General Directorate of Traffic.

Answer

The vehicle with more passengers goes first

Answer

The vehicle turning right goes first

Answer

The vehicle that stopped first has priority

Question 22

What is a key characteristic of large trucks and buses that drivers of cars need to be aware of on Qatar roads?

Accepted Answer

They have much larger blind spots on all four sides than a car. Large vehicles have substantial blind zones directly in front of the cab, directly behind the trailer, and along both sides for several metres. If you cannot see the truck driver's mirrors, the driver cannot see you. Do not linger alongside a large vehicle and avoid cutting in front of it without leaving a large gap, as trucks require much longer stopping distances.

Answer

They can stop in a shorter distance than cars due to multiple axle brakes

Answer

Their wide turning radius means they always indicate before turning

Answer

Their elevated cab position means they can see all vehicles around them

Question 23

What penalties can be imposed on a driver convicted of reckless or dangerous driving in Qatar?

Accepted Answer

Heavy fines, black points, possible imprisonment and vehicle confiscation, depending on the severity.. Reckless or dangerous driving is treated very seriously in Qatar. Courts can impose substantial fines, a significant number of black points, imprisonment and confiscation of the vehicle. The exact amounts can change, so always confirm the current schedule with the General Directorate of Traffic, for example via Metrash2.

Answer

Only a fine equivalent to a speeding ticket.

Answer

A compulsory driving refresher course with no other penalty.

Answer

Reckless driving carries a fixed three-day licence suspension only.

Question 24

How many continuous driving hours are generally permitted before a heavy vehicle driver must take a break in Qatar? (Confirm with the General Directorate of Traffic.)

Accepted Answer

Approximately 4 to 5 hours maximum before a rest break; confirm exact rules with the General Directorate of Traffic. Qatar applies driving-hours regulations to professional commercial vehicle drivers to reduce fatigue-related crashes. While exact limits should be confirmed with the General Directorate of Traffic, drivers are generally expected to take a break after approximately 4 to 5 hours of continuous driving. Fatigue impairs reaction time as severely as alcohol and is a leading cause of heavy vehicle crashes.

Answer

12 hours continuously if the driver feels alert

Answer

Driving hours for heavy vehicles are not regulated in Qatar

Answer

8 hours continuously, with a break only at the destination

Question 25

What is the minimum permitted following distance on Qatar expressways under normal conditions?

Accepted Answer

At least 3 seconds of gap from the vehicle ahead; confirm the exact metre requirement with the General Directorate of Traffic. Qatar law requires a safe following distance. While the three-second rule is a widely taught guideline, the legal minimum distance in metres may differ; confirm exact requirements with the General Directorate of Traffic to ensure compliance.

Answer

Exactly 5 metres at all times

Answer

Half a car length per 10 km/h of speed

Answer

There is no legal minimum following distance in Qatar

Question 26

Where must a child restraint seat be installed in a vehicle in Qatar?

Accepted Answer

In the rear seat, properly secured according to the manufacturer's instructions. Child seats should be fitted in the rear of the vehicle, secured according to the manufacturer's instructions and relevant regulations. The rear is the safest location in most crash scenarios. A forward-facing child seat should never be placed in front of an active airbag.

Answer

In the front passenger seat facing forward

Answer

In any seat, as long as the child is buckled in

Answer

In the front seat if the vehicle has no rear seat

Question 27

You are travelling uphill on a narrow mountain road and meet a vehicle coming downhill. Who should reverse or give way?

Accepted Answer

The vehicle travelling downhill should give way, as it is easier to reverse downhill and the uphill vehicle has momentum. On a steep narrow road, the vehicle going downhill is generally expected to give way by reversing to a passing place, because it has more control reversing downhill and because the uphill vehicle needs its momentum. Confirm with the General Directorate of Traffic.

Answer

The vehicle travelling uphill should give way because it can stop more easily

Answer

The smaller vehicle must always give way

Answer

Both vehicles stop and wait for a third party to direct them

Question 28

You are passing a large truck on a multi-lane expressway. Which action best keeps you safe?

Accepted Answer

Pass quickly and completely, then signal and move back to your lane leaving ample space. Lingering alongside a large vehicle keeps you in its blind spot. Pass decisively and return to your lane only when you can see the entire truck in your interior mirror with a comfortable gap. Large vehicles take much longer to stop, so cutting in too early risks being struck if the truck needs to brake suddenly.

Answer

Match the truck's speed and drive alongside it to reduce wind buffeting

Answer

Cut in front of the truck as soon as any part of it is behind you

Answer

Stay slightly behind the truck's cab to benefit from its slipstream

Question 29

A driver in Qatar repeatedly cuts between lanes at high speed on a busy expressway. Which category of offence does this most likely constitute?

Accepted Answer

Reckless or dangerous driving, which carries serious penalties beyond a simple lane-change fine.. Repeatedly weaving between lanes at high speed threatens the safety of all road users and goes beyond a simple lane-discipline violation. Qatar classifies such behaviour as reckless or dangerous driving, attracting heavy fines, black points and potential imprisonment. Using an indicator does not legalise an unsafe manoeuvre.

Answer

Only a lane-discipline infraction with a very small fine.

Answer

No offence as long as indicators were used.

Answer

An offence only if it causes another driver to brake sharply.

Question 30

What is the most effective way for a heavy vehicle driver to manage fatigue on a long overnight run?

Accepted Answer

Plan adequate sleep before the journey, take scheduled rest breaks, and stop to sleep if feeling drowsy. The only genuine remedy for fatigue is sleep. Caffeine and stimulation provide a temporary and unreliable boost and cannot substitute for adequate rest. Microsleep events lasting just two seconds at 100 km/h mean the vehicle travels 56 metres with no driver input. Drivers must plan rest into every long trip and stop immediately if drowsiness is felt.

Answer

Drink extra coffee and energy drinks throughout the drive to stay alert

Answer

Open the cab window and turn up the radio to stimulate alertness

Answer

Drive faster to reach the destination sooner and reduce overall time on the road
