What does a yellow traffic signal indicate?

A yellow traffic signal serves as a warning that the light is about to change to red. This signal indicates that drivers should prepare to stop if it is safe to do so. The intention behind this rule is to ensure that drivers have the opportunity to safely stop their vehicles rather than entering the intersection when the light turns red, which could lead to accidents.

The yellow light acts as an alert that the situation is changing, and instead of rushing to panic stop or accelerating through the intersection, a driver should assess their surroundings and make a decision based on safety. This may involve gradually slowing down and stopping if there is enough distance to do so safely. Understanding this principle helps promote safe driving habits and reduces the likelihood of collisions at intersections.
