What does a red traffic light indicate?

A red traffic light indicates that drivers must stop. This signal is a clear directive meant to control traffic and ensure safety at intersections or where traffic signals are present. When the light is red, it is crucial for drivers to come to a complete stop before the intersection and remain stopped until the light changes to green. This rule helps prevent accidents and allows for the safe passage of vehicles and pedestrians that may have the right of way.

It's important to note that proceeding with caution, yielding to pedestrians, or slowing down do not correctly convey the requirement imposed by a red light. Those actions may be appropriate in other traffic situations but do not align with the instructions provided by a red traffic signal. Understanding the requirement to stop is fundamental for safe driving and adherence to traffic laws.
