Below is a free Rules of the Road mock test for the UK DVSA car theory test: multiple-choice questions in the official four-option format, each with the correct answer, a plain-English explanation and a Highway Code reference. Speed limits, junctions, roundabouts, parking rules and rights of way.
Rules of the Road practice questions
Q1. What is the national speed limit for a car on a single carriageway?
- 50 mph
- 60 mph
- 70 mph
- 40 mph
Answer: B. For cars and motorcycles the national speed limit is 60 mph on a single carriageway and 70 mph on a dual carriageway or motorway. Limits are lower for vehicles towing. Reference: The Highway Code — Speed limits, rule 124
Q2. Unless signs show otherwise, what speed limit usually applies on a road with street lights?
- 20 mph
- 30 mph
- 40 mph
- 50 mph
Answer: B. A road with regular street lighting usually has a 30 mph limit unless signs tell you otherwise. In Wales the default limit on restricted roads is 20 mph. Reference: The Highway Code — Speed limits, rule 124
Q3. When may you enter a box junction marked with yellow criss-cross lines?
- Whenever the traffic lights are green
- Only when your exit road is clear — or to turn right while waiting for oncoming traffic
- Never, box junctions are for buses only
- When at least half the box is clear
Answer: B. You must not enter the box unless your exit is clear. The exception: you may wait in the box to turn right when only oncoming traffic or other right-turning vehicles stop you. Reference: The Highway Code — rule 174
Q4. When you reach a roundabout, who should you normally give way to?
- Traffic approaching from your left
- Traffic already signalling to exit
- Traffic approaching from your right, unless signs or markings say otherwise
- Nobody — the vehicle on the roundabout gives way
Answer: C. On approach, give priority to traffic coming from your immediate right unless signs, markings or lights indicate otherwise. Watch cyclists and motorcyclists, who are harder to see. Reference: The Highway Code — rule 185
Q5. At night, how should you park on a two-way road with a 40 mph limit?
- Anywhere, with hazard lights on
- Facing oncoming traffic so your reflectors show
- In the direction of the traffic flow, with parking lights on
- On the pavement to keep the road clear
Answer: C. On roads with a limit above 30 mph you must not park at night facing against the traffic flow, and you must show parking lights — your rear reflectors only work facing the right way. Reference: The Highway Code — rules 248–249
Q6. When may you cross a solid white line along the centre of the road?
- Whenever the road ahead is clear
- To pass a stationary vehicle, or overtake a cyclist, horse or road maintenance vehicle moving at 10 mph or less — or to turn into a property or side road
- Only at night
- Never, in any circumstances
Answer: B. A solid white centre line on your side bans crossing it except for the listed exceptions: turning in, passing something stationary, or passing a cyclist, horse or works vehicle at 10 mph or under. Reference: The Highway Code — rule 129
Q7. What do yellow zigzag lines outside a school mean?
- Parking for parents at drop-off times
- Keep the marked area clear — do not stop or park there, even briefly
- Loading permitted for 10 minutes
- Bus stop ahead
Answer: B. The zigzags keep sightlines clear so children and drivers can see each other. Stopping there — even 'just for a minute' — is exactly what causes school-gate collisions, and upright signs make it enforceable. Reference: The Highway Code — rule 238 and Road markings
Q8. Where must you never overtake?
- On any dual carriageway
- Approaching a pedestrian crossing — you must not overtake the moving vehicle nearest the crossing or one that has stopped for it
- Within 100 metres of any junction
- On roads with street lighting
Answer: B. The vehicle you'd pass may be slowing or stopped precisely because someone is crossing — overtaking it drives you blind into the crossing. It's one of the most serious overtaking offences. Reference: The Highway Code — rules 165 and 191
