Triangular projection markers are required when your load is wider than 2.9 metres (9 feet 6 inches). What colour are these markers?
- A Black/yellow
- B Red/yellow
- C Black/white
- D Red/white
Why this is the answer
The marker boards should be red and white. They must be kept clean and independently lit at night and in poor visibility, so that other road users can see them.
Why the other answers don't fit
- A
- Black/yellow — Black and yellow is a hazard pattern used elsewhere, not on projection markers.
- B
- Red/yellow — Red and yellow is the rear marking pattern for heavy goods vehicles.
- C
- Black/white — Black and white is not used for these markers.

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.
