What does a steady red light signal to drivers?

A steady red light is one of the most universally recognized signals in traffic control. It indicates that drivers must come to a complete stop at the intersection or at the line marked for stopping. The purpose of the steady red light is to ensure safety by preventing collisions at intersections where vehicles may have conflicting movements.

When faced with a steady red light, drivers are required to wait until the light changes to green before proceeding. This rule helps to manage traffic flow and protect pedestrians who may be crossing the intersection.

In contrast, other signals like a yellow light suggest caution and preparation to stop, while a green light indicates that it is safe to proceed. Therefore, a steady red light clearly conveys the instruction to stop, making it critical for drivers to follow for their safety and the safety of others on the road.
