What does a red traffic light mean?

A red traffic light signifies that drivers must stop and remain stopped until the light turns green. This is critical for maintaining safety at intersections, as it prevents collisions by ensuring that vehicles do not enter the intersection while other vehicles or pedestrians have the right of way. When the light is red, it is a clear indication that it is not safe to proceed, and compliance is essential for the orderly flow of traffic and the safety of all road users.

Options that suggest proceeding with caution, yielding to cross traffic, or stopping only if pedestrians are present do not align with the established rules of traffic control signals. These alternatives could lead to confusion and potentially dangerous situations on the road. Therefore, understanding that a red traffic light specifically commands a complete stop is crucial for safe driving practices.
