What does a solid red traffic light mean?

Answer: B — Stop and remain stopped until the light turns green

A solid red traffic light indicates that drivers must come to a complete stop and remain stopped until the light turns green. This rule is essential for maintaining traffic order and safety at intersections. When faced with a red light, vehicles must halt before the stop line, crosswalk, or intersection, ensuring that they do not interfere with the flow of traffic in other directions that have a green light. When the light turns green, it is safe to proceed, but drivers should first check for any pedestrians or other vehicles that may still be in the intersection. This rule is in place to prevent accidents and ensure everyone's safety on the road. Understanding the significance of traffic signals and obeying them is crucial for all drivers to promote safe driving practices.
