What does a red light mean when driving?

A red light indicates that drivers must come to a complete stop at the intersection. This rule is crucial for maintaining safety on the road. When the light turns red, it is a signal for vehicles to cease movement and wait for the light to change to green before proceeding. This regulation allows for controlled traffic flow and helps prevent accidents by ensuring that opposing traffic can move freely when the light changes.

The critical nature of this signal emphasizes the importance of obeying traffic lights. Ignoring a red light can lead to serious ramifications, including collisions and legal penalties. Understanding that a red light denotes a full stop is essential for all drivers to navigate intersections safely.
