What does this sign mean?
- A Vehicle carrying dangerous goods in packages
- B Vehicle broken down ahead
- C Holiday route
- D Emergency diversion route for motorway traffic
Why this is the answer
Major roadworks often cause complicated diversions for large vehicles. Drivers may be advised to follow a special symbol until the original road can be rejoined. Look for the yellow-and-black symbols in these shapes: • square • triangle • diamond • circle. They'll often be shown with additional information and will help guide you around the diversion.
Why the other answers don't fit
- A
- Vehicle carrying dangerous goods in packages — Dangerous goods are marked on the vehicle, by an orange panel.
- B
- Vehicle broken down ahead — A broken-down vehicle is warned by hazard lights and matrix signs.
- C
- Holiday route — Holiday routes are signed with their own wording and colours.

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.
