What does a yellow traffic light indicate?

A yellow traffic light indicates that drivers should prepare to stop. This sign is a warning that the light is about to change to red, and vehicles should be prepared to halt their movement. The purpose of the yellow light is to provide sufficient time for drivers to react, allowing for a safe transition from the green light to the red light. This means that if a driver is already in the intersection when the light turns yellow, they should continue moving to clear the intersection safely. However, if they are approaching the intersection and can safely stop before the light turns red, they should do so.

Understanding this signal is crucial for promoting safety on the road, as it helps prevent accidents that might occur from unexpected stops or running a red light. The other options might suggest actions that could lead to confusion or unsafe driving behavior when the light changes to yellow.
