Which of these signs means turn left ahead?
- A
- B
- C
- D
Why this is the answer
This sign gives a clear instruction. You should prepare to negotiate a left-hand turn.
Why the other answers don't fit
- A
- — A straight horizontal arrow orders the turn at the sign itself, not at a junction further on.
- C
- — A single diagonal arrow means keep left — pass this side of an island. The road does not turn.
- D
- — Two diagonal arrows mean you may pass on either side of what is ahead.

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.
