When may you turn right on a red light?

The correct answer is:

1. If there is a green arrow pointing right, or a green light for straight ahead with no red right turn arrow.

The importance of this rule lies in ensuring the orderly and safe flow of traffic. Under a red light, the general rule is that vehicles from all directions must stop and wait, unless there is a specific indication (such as a green arrow pointing right) allowing a turn or straight movement in a certain direction. Such regulations help prevent collisions at intersections by clearly indicating which vehicles can safely proceed through the intersection at a specific time. The absence of such regulations may lead to drivers misunderstanding the intentions of the traffic signals, thereby increasing the risk of traffic accidents. By adhering to these rules, drivers can better understand traffic flow, avoid unnecessary delays, and prevent potential accidents, ensuring the safety of everyone on the road.
