You see this 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
The amber light means stop. You may only go on if the light changes to amber after you've crossed the stop line or when you're so close to the line that stopping might cause a collision. The amber light is followed by the red light. You must wait behind the stop line until the green light shows.
Why the other answers don't fit
- B
- Red and amber together — Red and amber together comes after red, not before it.
- C
- Green and amber together — Green and amber are never shown together.
- D
- Green alone — Green follows red and amber, two steps further on.

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.
