DVSA Highway Code Rules 3 — Questions and Answers
Question 1: What are the rules regarding parking on double yellow lines?
- You may park for up to 5 minutes
- You must not wait or park at any time (Correct answer)
- You may park outside business hours
- You may park if you stay with the vehicle
Correct answer: You must not wait or park at any time
Double yellow lines mean no waiting at any time. You must not park or wait on them. Limited exceptions exist for loading/unloading (unless kerb marks prohibit it) and disabled Blue Badge holders (up to 3 hours).
Question 2: At a crossroads with no signs or markings, who has priority?
- Traffic from the right always has priority
- Traffic on the wider road has priority
- Nobody has priority — all drivers must proceed with caution (Correct answer)
- Traffic going straight ahead has priority
Correct answer: Nobody has priority — all drivers must proceed with caution
At an unmarked crossroads, no one has priority. All drivers should approach with extreme caution, slow down, and be prepared to give way. Look in all directions and proceed only when safe.
Question 3: When must you use your headlights?
- Only at night
- Only in fog
- Between sunset and sunrise, and in seriously reduced visibility (Correct answer)
- Only on unlit roads
Correct answer: Between sunset and sunrise, and in seriously reduced visibility
You must use headlights between sunset and sunrise and at any time when visibility is seriously reduced (generally below 100 metres). Sidelights alone are not sufficient in these conditions.
Question 4: What is the legal blood alcohol limit for drivers in England and Wales?
- 50 milligrammes per 100 millilitres of blood
- 80 milligrammes per 100 millilitres of blood (Correct answer)
- Zero — no alcohol at all
- 100 milligrammes per 100 millilitres of blood
Correct answer: 80 milligrammes per 100 millilitres of blood
In England and Wales, the legal drink-drive limit is 80 milligrammes of alcohol per 100 millilitres of blood (or 35 microgrammes per 100 millilitres of breath). In Scotland, the limit is lower at 50 mg. The safest advice is not to drink at all if driving.
Question 5: On a clearway, what are you prohibited from doing?
- Exceeding 40 mph
- Using your horn
- Stopping at any time, including to pick up or set down passengers (Correct answer)
- Overtaking
Correct answer: Stopping at any time, including to pick up or set down passengers
On a clearway, you must not stop at any time on the main carriageway, even to pick up or set down passengers. This keeps the road clear for the free flow of traffic. The clearway sign is a red 'X' on a blue background.
Question 6: What is the speed limit for cars on a dual carriageway?
- 50 mph
- 60 mph
- 70 mph (Correct answer)
- No limit
Correct answer: 70 mph
The national speed limit for cars and motorcycles on dual carriageways is 70 mph — the same as on motorways. Goods vehicles over 7.5 tonnes are limited to 60 mph on dual carriageways.
