What does a red traffic light mean?

A red traffic light signifies a requirement for vehicles to come to a complete stop. This is a fundamental traffic rule that helps ensure the safety of all road users, as it prevents collisions at intersections by controlling the flow of traffic. When a driver encounters a red light, they must halt their vehicle before the crosswalk or intersection line and remain stopped until the light changes to green.

Understanding the significance of a red light is crucial for safe driving. It indicates that vehicles must yield to cross traffic that has the right of way, allowing pedestrians to cross safely as well. Ignoring this signal can lead to serious traffic violations and accidents.
