When is a buffer lane most likely to be in use?
- A When it's windy
- B When it's raining
- C When it's foggy
- D When it's icy
Why this is the answer
A buffer lane is used when the wind begins to cause a risk to high-sided vehicles. At other times, it will be a normal lane. Do not use the buffer lane unless your vehicle has been blown off course into the lane, or you need to use it to avoid an incident or collision.
Why the other answers don't fit
- B
- When it's raining — Rain affects grip and visibility, not whether you are blown sideways.
- C
- When it's foggy — Fog hides things; it does not push vehicles across lanes.
- D
- When it's icy — Ice is a grip problem dealt with by salt and speed.

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.
