Explanation of the meanings of a red arrow pointing to the right on a traffic light and the role of traffic engineers and crossing guards in road safety.
Explanation:
Red arrow pointing to the right on a traffic light means you may:
- Turn right after you have come to a complete stop
- Not turn right until the light turns green
- Turn right after slowing and checking traffic
Traffic engineers design the duration of the yellow signal to ensure safe passage through stoplights, eliminating the 'no-win' zone for drivers.
Crossing guards use the extended hand symbol to signal vehicles and pedestrians to stop for safe road crossing.
