Unless otherwise shown, what's the minimum headroom under bridges in the UK?
- A 4 metres (13 feet 1 inch)
- B 4.1 metres (13 feet 5 inches)
- C 5.0 metres (16 feet 6 inches)
- D 5.5 metres (18 feet)
Why this is the answer
Every year, there are hundreds of incidents in the UK where vehicles hit railway or motorway bridges. Most involve buses, coaches and lorries. Make sure your route does not take you under a bridge that's too low for your vehicle. If you hit a bridge, you'll be putting yourself and any passengers at risk, and you could cause a major disruption to road and rail transport.
Why the other answers don't fit
- A
- 4 metres (13 feet 1 inch) — Four metres is a common signed height, which is why it would be signed.
- B
- 4.1 metres (13 feet 5 inches) — 4.1 metres is also low enough to need a sign.
- D
- 5.5 metres (18 feet) — 5.5 metres is more clearance than the rule guarantees.
Where this comes from
- Driving Buses and Coaches — section 3, section 6

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.
