What does a solid red traffic light mean?

A solid red traffic light signals drivers to stop completely. This is a critical traffic regulation designed for safety. When you encounter a solid red light, it is mandatory to bring your vehicle to a complete halt at the designated stopping point, which is typically marked by a stop line or crosswalk. You must remain stopped until the light changes to green, indicating that it is safe to proceed. This rule helps to prevent accidents and ensures the orderly flow of traffic, as it allows other vehicles and pedestrians to move safely through intersections.

The other responses do not accurately reflect the actions required when facing a solid red light. For example, slowing down and preparing to stop might be relevant when approaching a yellow light, but it does not apply to a red light, which requires a complete stop. Proceeding with caution is not appropriate for a red light; the indication is to stop. Yielding to pedestrians may be necessary when the light changes and pedestrians are present, but it does not replace the requirement to stop at a red light.
