Correct answer: Reduce speed below the limit to suit conditions
Poor conditions reduce grip and visibility; slow well below the limit.

Question 5
What is the basic principle for choosing your driving speed?
Also show inShow answer

Question 6
Stopping distance is made up of:
Also show inShow answer
Correct answer: Reaction distance plus braking distance
Stopping distance runs from the moment you notice danger to a complete stop: reaction (perception) distance plus braking distance.

Question 7
The handbook estimates a standard reaction time of about:
Also show inShow answer
Correct answer: One second
A standard reaction time is about one second, so reaction distance is the distance travelled in one second, without slowing down.

Question 8
What makes your reaction distance longer? Select all that apply.
Select all that apply.
Also show inShow answer
Correct answers: Higher speed · Distraction or tiredness · Drowsy-making medicines or drugs
Reaction distance grows at high speed, when you are distracted or tired, and under the influence of drugs, drowsy medication or alcohol.

Question 9
What makes your braking distance longer? Select all that apply.
Select all that apply.
Also show inShow answer
Correct answers: A heavy load · Sand or water on the road · Worn tyres or faulty brakes
Braking distance is longer at high speed, with a heavy load, on poor surfaces (sand, water), with bad tyres and with faulty brakes.

Question 10
According to the handbook's table, about how far does a car travel before stopping from 100 km/h (reaction plus braking, dry road)?
Also show inShow answer
Correct answer: 130 m
At 100 km/h: about 30 m reaction distance plus 100 m braking distance, so roughly 130 m in total.
Reference: GDT Theoretical Driving Handbook (Dallah), p. 16 (https://www.ddc.sa/uploads/image/downloadables_pdf/Theoretical%20Driving%20Handbook%20Trainee-Moroor.pdf, retrieved 2026-10-27)
Question 11
Doubling your speed from 50 km/h to 100 km/h does what to the braking distance in the handbook's table?
Also show inShow answer
Correct answer: It roughly quadruples (25 m to 100 m)
Braking distance grows with the square of speed: 25 m at 50 km/h becomes 100 m at 100 km/h.

Question 12
What is the minimum following distance behind another vehicle?
Also show inShow answer
Correct answer: Two seconds
The minimum distance behind another vehicle is two seconds, so you can react and stop if the vehicle ahead brakes suddenly.

Question 13
When should you increase your safety distance? Select all that apply.
Select all that apply.
Also show inShow answer
Correct answers: On a wet or sandy road · Behind motorcycles on a single-lane road · When your vehicle is heavily loaded
Increase the gap in bad road conditions (wet or sandy), behind vehicles such as motorcycles on single-lane roads, and when driving a heavily loaded vehicle.

Question 14
With no other sign, what is the maximum speed for large vehicles on roads within cities?
Also show inShow answer
Correct answer: 50 km/h
Unless signs show otherwise, large vehicles may not exceed 50 km/h on city roads. Outside cities they follow the road's posted speed.

Question 15
Where should you reduce your speed? Select all that apply.
Select all that apply.
Also show inShow answer
Correct answers: Approaching intersections and crossings · Before bends · In tunnels and on bridges
Slow down near intersections and crossings, before bends, on bridges, at railway crossings, in tunnels, in low visibility and on slippery roads.

Question 16
What does a minimum speed sign tell you?
Also show inShow answer
Correct answer: Not to drive slower than the speed shown, unless conditions or safety require it
A minimum speed sign means don't drive slower than the figure shown. You may go slower if the situation or safety requires it.

Question 17
Driving very slowly without a good reason, so that you obstruct other vehicles, is prohibited.
Also show inShow answer
Correct answer: True
True. Obstructing traffic by driving very slowly without reason, and braking suddenly when not needed for safety, are both banned.

Question 18
You need to slow down. How should you let drivers behind you know in time?
Also show inShow answer
Correct answer: With the brake lights, or a hand signal
If you slow down, indicate it in time using the brake lights at the rear of the vehicle or hand signals.

Question 19
Racing vehicles on public roads is:
Also show inShow answer
Correct answer: Prohibited inside and outside cities
Racing on public roads is prohibited inside and outside city limits. Drifting is an illegal form of road racing and is severely punished.

Question 20
In the handbook's example, you are 10 km/h faster (60 instead of 50 km/h) when a truck pulls out ahead. What is the result?
Also show inShow answer
Correct answer: You can't stop in time and hit the truck at about 40 km/h
At 50 km/h you stop in time; at 60 km/h you still hit the truck at about 40 km/h. Just 10 km/h over the limit can cause serious injury.
