Theory Hub UK Theory Test

What should you do if the traffic in the left-hand lane is slowing?

Why this is the answer

Allow the traffic to merge into the left-hand lane. Leave enough room so that you can maintain a safe separation distance, even if vehicles pull in ahead of you.

Why the other answers don't fit

B
Accelerate past the vehicles in the left-hand lane — Speeding past traffic that is merging is how a merge fails.
C
Pull up on the left-hand verge — There is no reason to stop, and the verge is not a lane.
D
Move across and continue in the right-hand lane — Changing lane to avoid the merge leaves the joining traffic nowhere to go.

Where this comes from

  • Driving: the essential skills — section 10
  • The Highway Code — rule 289

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.
