What does a red traffic light mean?

Answer: C — Stop and do not proceed until the light turns green

A red traffic light signifies that vehicles must come to a complete stop and cannot proceed until the light changes to green. This rule is essential for maintaining safety on the roads, as it helps regulate the flow of traffic and reduces the likelihood of collisions. When approaching a red light, drivers are expected to stop behind the designated stop line, allowing pedestrians and vehicles from other directions the opportunity to move safely. This understanding underlines the importance of traffic signals in managing intersections and ensuring that all road users can navigate safely. By adhering to the instruction of a red light, drivers demonstrate compliance with traffic laws and contribute positively to overall road safety.
