What does a solid red traffic light indicate?

A solid red traffic light indicates that a driver must come to a complete stop and cannot proceed until the light turns green. This signal is used to help control the flow of traffic and enhance safety at intersections. When a light is red, all vehicles and pedestrians must cease movement to prevent accidents and allow for the safe passage of cross traffic.

The requirement for a full stop applies regardless of the circumstances, ensuring that all drivers understand the need to halt completely when facing a red light. This rule helps maintain order on the roads and contributes to a systematic approach to traffic control. Understanding this concept is crucial for safe driving practices and obeying traffic regulations.
