Q: Is this the real exam?

These are practice questions to help you revise, written to the published rules and to what candidates report from the real test. They are not the official Saudi exam and the real question bank, format, fees and pass mark are set by the General Department of Traffic (Moroor) and the driving schools, and can change. Always confirm the current requirements with your driving school or the traffic department.

Q: Is this practice test free?

The first 10 questions are free, with no signup, and each shows the answer and the reason. The full 35-question test, timed, is in the Saudi Driving Theory Online Practice Bank (SAR 39, one payment), with every question in the bank.

Q: What does the Northern Borders 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

Why does a fully loaded articulated truck require a much greater stopping distance than a private car travelling at the same speed?

Accepted Answer

Greater mass gives the truck far more kinetic energy, so the brakes must absorb much more energy before the vehicle stops. A fully loaded truck has far greater mass than a car, which means far more kinetic energy at any given speed. The brakes must absorb all that energy before the vehicle stops, so the stopping distance is significantly longer. Always allow a large gap to the vehicle ahead.

Answer

Truck air brakes are slower to react than a car's hydraulic brakes

Answer

Truck tyres are wider and create more wind resistance, which slows the braking

Answer

A loaded truck sits lower, reducing tyre contact and grip

Question 2

What must you do when you see this sign?

Accepted Answer

Slow down and give way to traffic on the road you are joining. The downward-pointing triangle is the Give Way sign. You must slow down and yield to any vehicle or pedestrian on the road you are joining. Unlike a STOP sign, you do not always have to come to a complete halt, but you must be ready to stop if the road is not clear.

Answer

Stop completely every time, even when the road is clear

Answer

You have priority - continue without slowing

Answer

Sound your horn before entering the junction

Question 3

You are driving at normal speed on a three-lane expressway and you have just finished overtaking. What should you do?

Accepted Answer

Return to the right lane as soon as it is safe. The correct answer is to return to the right lane as soon as it is safe. Saudi regulations follow the keep-right rule: the passing (left) lane is only for overtaking. Lingering in it after completing an overtake is illegal.

Answer

Stay in the middle lane so you can overtake again quickly

Answer

Move to the left lane for safety

Answer

Remain in your current lane until the next junction

Question 4

At an unmarked equal junction, three vehicles arrive at the same time from the north, east, and west (there is no vehicle from the south). Under the give-way-to-the-right rule, which vehicle has priority to go first?

Accepted Answer

The vehicle coming from the west, because it has no vehicle on its right. Give way to the vehicle on your right. The vehicle from the west is heading east, so its right side faces the empty south approach; with no one on its right it has priority and goes first. The vehicle from the north must give way to the west vehicle, and the vehicle from the east must give way to the north vehicle.

Answer

The vehicle coming from the north

Answer

The vehicle coming from the east

Answer

All three must stop and wait for a signal from another driver

Question 5

Under what conditions should you at least double your following distance to 6 seconds or more?

Accepted Answer

When driving in rain, fog, sandstorm, or when fatigued. The correct answer is when driving in rain, fog, sandstorm, or when fatigued. In these conditions your reaction time is longer and your brakes are less effective, so doubling the gap to 6 seconds or more gives a vital safety margin.

Answer

Only on gravel roads

Answer

Only when overtaking a truck

Answer

Only at night in a city

Question 6

An expatriate driver is convicted of a drink-driving offence in Saudi Arabia. Which additional consequence beyond fines and imprisonment is highly likely?

Accepted Answer

Deportation from the Kingdom. For expatriate residents, a drink-driving conviction routinely leads to deportation after serving any custodial sentence. Saudi Arabia treats alcohol-related offences as serious criminal matters, and immigration authorities typically cancel the residency permit (Iqama) of those convicted.

Answer

A compulsory defensive-driving course only

Answer

Community service and a warning letter to the employer

Answer

A temporary suspension of the driving licence for 30 days

Question 7

Compared with the same truck when empty, a fully laden heavy truck travelling at 80 km/h will have a stopping distance that is

Accepted Answer

Considerably longer, because higher mass requires more braking force over a greater distance. A laden truck has considerably longer stopping distance than the same truck when empty. Higher mass means more kinetic energy, and the brakes must work much harder over a greater distance. This effect is even more pronounced on wet or sandy roads.

Answer

Roughly the same, because the brakes are identical on the laden and unladen vehicle

Answer

Slightly shorter, because added weight presses the tyres harder onto the road

Answer

Shorter only on wet roads, due to the extra mass improving tyre adhesion

Question 8

What does this sign tell you?

Accepted Answer

The maximum speed allowed is 40 km/h. A black number inside a red circle is a maximum speed-limit sign. Here the limit is 40 km/h. This limit is common in residential zones and near schools in Saudi Arabia. Driving above the posted limit is a traffic violation and can result in fines and black points.

Answer

The minimum speed on this road is 40 km/h

Answer

You are 40 km from the city centre

Answer

The speed limit applies only between 40-minute intervals

Question 9

Which of the following is the correct way to enter a roundabout in Saudi Arabia?

Accepted Answer

Give way to vehicles already circulating inside the roundabout. The correct answer is to give way to traffic already inside the roundabout. Saudi traffic law requires drivers approaching a roundabout to yield to circulating vehicles before entering. Always check for gaps before proceeding.

Answer

Vehicles entering have priority over those already inside

Answer

Sound your horn and enter without stopping

Answer

Flash your headlights to warn drivers inside, then enter

Question 10

You are about to enter a roundabout. Traffic is already circulating inside. Who has priority?

Accepted Answer

Vehicles already circulating inside the roundabout have priority. Circulating traffic inside a roundabout has priority over vehicles trying to enter. You must give way and wait for a safe gap before entering. Not giving priority to vehicles inside a roundabout is a table 4 violation (SR 500-900) and carries 6 points.

Answer

Vehicles entering the roundabout have priority

Answer

The vehicle to your right at the entry has priority

Answer

Both vehicles have equal priority
