You see this amber traffic light ahead. Which light, or lights, will come on next?
- A Red alone
- B Red and amber together
- C Green and amber together
- D Green alone
Why this is the answer
At junctions controlled by traffic lights, you must stop behind the white line until the lights change to green. A red light, an amber light, and red and amber lights showing together all mean stop. You may proceed when the light is green unless your exit road is blocked or pedestrians are crossing in front of you. If you’re approaching traffic lights that are visible from a distance and the light has been green for some time, be ready to slow down and stop, because the lights are likely to change.
Why the other answers don't fit
- B
- Red and amber together — That pair comes after red, not after amber.
- C
- Green and amber together — No British signal shows those two together.
- D
- Green alone — Green follows red and amber, not a single amber.

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.
