What's a buffer lane?
- A A safety lane for vehicles blown off course
- B A lane for overtaking safely
- C A lane to park in until the wind drops
- D The only lane to be used in high winds
Why this is the answer
During high winds, one of the lanes on a high bridge might be closed to traffic to create a buffer lane. The buffer lane is kept free to prevent vehicles from being blown into the path of other road users in the next lane. The closure of this lane may cause traffic congestion and delay.
Why the other answers don't fit
- B
- A lane for overtaking safely — It is not an overtaking lane; it is space left deliberately empty.
- C
- A lane to park in until the wind drops — Nobody parks in it; it is a running-width allowance.
- D
- The only lane to be used in high winds — It is not the lane to use, but the one kept clear beside you.

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.
