A symbol is painted on the pavement at an intersection with traffic lights. What does it show?

  2. A school zone
  3. That parking is allowed
  4. Where to stop to be detected
Show answer

Correct answer: Where to stop to be detected

The vehicle sensor symbol shows the right place to stop. The sensor then tells the traffic light that you are there, which can shorten waiting times.
