What's the national speed limit for cars and motorcycles on a dual carriageway?
- A 30 mph
- B 50 mph
- C 60 mph
- D 70 mph
Why this is the answer
Make sure that you know the speed limit for the road that you're on. The speed limit on a dual carriageway or motorway is 70 mph for cars and motorcycles, unless signs indicate otherwise. The speed limits for different types of vehicle are listed in The Highway Code.
Why the other answers don't fit
- A
- 30 mph — The usual limit in a built-up area.
- B
- 50 mph — Often signed at roadworks, but it is not a national limit.
- C
- 60 mph — The national limit on a single carriageway, and the limit here if you are towing.
Where this comes from
- The Highway Code — page 48

Where this question comes from
The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence. The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites. Everything else on this page is written by Theory Hub: the explanation of why each wrong answer is wrong, the topic guide and the revision notes.
