What does a solid red light mean?

A solid red light indicates that drivers must come to a complete stop at the marked stop line, intersection, or before entering the crosswalk. This signal is a clear directive to halt all movement towards the intersection until the light changes to green. It's essential for ensuring safety, as it helps manage the flow of traffic and protect pedestrians who may be crossing the road.

When a vehicle is stopped at a red light, it cannot proceed until the light turns green, regardless of the conditions of the traffic around them. This establishes a universal rule that all drivers must follow, promoting consistency in driving behavior at intersections. Adhering to this signal prevents accidents and ensures that all road users understand when it is safe to proceed.
