What does a red light signify?

A red light signifies that drivers must come to a complete stop and must not proceed through the intersection until the light changes to green. This rule is crucial for maintaining safety on the road, as it ensures that vehicles are not moving when it is dangerous to do so, particularly when cross traffic or pedestrians may be present. This signal is part of the traffic control system designed to manage the flow of vehicles and reduce the potential for accidents.

The requirement to stop at a red light applies regardless of the presence of other vehicles or pedestrians, emphasizing that traffic lights dictate vehicle movement for everyone's safety. Recognizing and obeying this signal is fundamental for all drivers, reflecting a shared responsibility to uphold traffic laws and ensure safe interactions on the road.
