You're driving a lorry carrying a load that's 4.5 metres (14 feet 9 inches) wide. What's the maximum speed you're allowed to drive on a motorway?
- A 10 mph
- B 20 mph
- C 30 mph
- D 40 mph
Why this is the answer
The speed limits imposed on vehicles carrying abnormal loads can be frustrating for other drivers, but you must not be tempted to exceed them. Remember, the more weight you're carrying, the longer it will take you to stop safely.
Why the other answers don't fit
- A
- 10 mph — Ten miles an hour on a motorway would be a hazard in itself.
- B
- 20 mph — Twenty is still far below what the rules set for this width.
- C
- 30 mph — Thirty is close, and the regulation names a higher figure.
Where this comes from
- Driving Goods Vehicles — section 3
Rule numbers link to The Highway Code on gov.uk.
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.
