What is the proper action when a traffic signal turns yellow?

When a traffic signal turns yellow, the appropriate action is to prepare to stop if it is safe to do so. This means that drivers should take this signal as a warning that the light is about to turn red. The intent of the yellow light is to allow for a safe transition from green to red, indicating that it is time to slow down and prepare to stop rather than to accelerate through the intersection.

In many situations, if you are too close to the intersection to stop safely, you may need to proceed with caution; however, if there is enough distance and time to stop safely before the intersection, that is the preferred action. This helps to avoid potential collisions and ensures that the intersection remains safe for all road users.

Being aware of the implications of a yellow light helps to promote defensive driving and contributes to overall traffic safety.
