Theory Hub UK Theory Test

You've broken down on a two-way road. You have a warning triangle. At least how far from your vehicle should you place the warning triangle?

Why this is the answer

Advance warning triangles fold flat and do not take up much room. Use one to warn other road users if your vehicle has broken down or if there has been an incident. Place it at least 45 metres (147 feet) behind your vehicle (or the incident), on the same side of the road or verge. Place it further back if the scene is hidden by, for example, a bend, hill or dip in the road. Do not use warning triangles on motorways.

Why the other answers don't fit

A
5 metres (16 feet) — So close that a driver would reach your car before they had reacted to the triangle.
B
25 metres (82 feet) — Still short of the distance the rule gives.
D
100 metres (328 feet) — Further than is asked for. The figure to remember is 45 metres.

Where this comes from

  • Driving: the essential skills — section 15
  • The Highway Code — rule 276

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.
