What does a red traffic light mean?

A red traffic light signifies that drivers must come to a complete stop behind the stop line or crosswalk. This signal is crucial for ensuring safety at intersections, as it indicates that vehicles must wait until the light changes to green before proceeding. The primary purpose of a red light is to control traffic flow and prevent accidents by clearly indicating when vehicles should not enter the intersection. Understanding and complying with this rule is essential for safe driving practices, as it helps manage the rights of way among all road users, including vehicles and pedestrians.
