What does a red light indicate at an intersection?

A red light at an intersection is a clear indication for drivers that they must stop and wait until it is safe to proceed. The traffic light’s color signifies that vehicles cannot continue their movement into the intersection; doing so would violate traffic laws and could lead to accidents. Stopping at a red light ensures the safety of all road users, including vehicles traveling crosswise and pedestrians who may be crossing the street.

Understanding this rule is crucial for maintaining order on the roads and for preventing collisions. The other options may suggest alternative actions or reduce the urgency of stopping, which could lead to dangerous situations. Following the directive that a red light commands is essential for safe driving practices.
