What does a red traffic light mean?

A red traffic light indicates that drivers must come to a complete stop at the intersection. This is a fundamental traffic rule designed to ensure safety on the roads. A stop is required because the red light signifies that it is not safe to proceed through the intersection due to cross traffic or pedestrians.

When a vehicle approaches a red light, it is essential for the driver to stop before the intersection or before the crosswalk, depending on where the stop line is located. This rule is in place to prevent accidents and maintain orderly traffic flow.

In this scenario, other choices do not accurately reflect the meaning of a red light. Proceeding with caution or making a U-turn would compromise safety and the traffic regulations established to protect all road users. Yielding to pedestrians is also a critical practice at intersections, but it occurs when the light is green or when pedestrians are present at an intersection. Thus, understanding that a red light means stop is crucial for safe driving practices.
