What is the meaning of traffic lights?
1. RED obviously means STOP and wait behind the STOP line on the carriage way.
2. AMBER/YELLOW means STOP at the line. You may only proceed if the AMBER appears after you have crossed the STOP line and stopping might lead to an accident.
3. GREEN means that you can proceed. A GREEN arrow means that you may GO in the direction shown by the arrow and not in any other direction.
