What does a red light mean for vehicles?

A red light signifies a clear and universal traffic rule that vehicles must come to a complete stop at the intersection. It indicates that the driver is required to wait until the light turns green before proceeding. This rule is critical for maintaining safety on the roads, as it helps prevent collisions that could occur if vehicles were allowed to move through the intersection while traffic is flowing in the opposite direction or where pedestrians may be crossing.

Observing a red light ensures that drivers respect the right-of-way rules, allowing for a controlled flow of traffic and adhering to the laws that govern road usage. Compliance with red light signals is essential for ensuring the safety of all road users, including pedestrians and other vehicles. This understanding forms a foundational aspect of responsible driving behavior.
