A traffic light with a black box and three round lamps, with only the middle lamp lit in amber

When may you go through this signal?

  1. Whenever the road ahead is clear
  2. When you are within 50 metres
  3. When you can drive faster than 30 mph
  4. Only if you cannot stop safely before the line
Show answer

Correct answer: Only if you cannot stop safely before the line

Amber means stop at the line. Go on only if you are already over the line, or too close to stop without risk of a crash.
