What does a solid red traffic light mean?

A solid red traffic light signifies that drivers must stop their vehicles and wait until the light turns green before proceeding. This rule is in place to ensure safety at intersections and prevent accidents by controlling the flow of traffic. When the light is red, vehicles must come to a complete stop before the designated stop line or crosswalk. It’s also important to remain stopped until the light changes to green, as this indicates a safe time to continue driving.

While other options may represent different traffic scenarios, none of them align with the meaning of a solid red light. For example, proceeding with caution is not appropriate when a red light is showing; drivers must stop completely. Yielding to pedestrians is a separate consideration and does not negate the requirement to stop. Turning left only implies a specific action that is not allowed under a red light unless there are signs permitting such a maneuver. Understanding the implications of a solid red light is crucial for maintaining safety on the road.
