A yellow traffic light indicates what?

A yellow traffic light serves as a warning that the light is about to change to red. It is an indication for drivers to prepare to stop if it is safe to do so. The primary purpose of this signal is to alert drivers that they should clear the intersection and not proceed through it if they can't safely do so.

Choosing to speed up to clear the intersection can be dangerous, as it may lead to accidents if other vehicles are also entering the intersection. Ignoring the signal entirely undermines the purpose of traffic lights and can result in dangerous situations. Turning left or right immediately does not account for the fact that the signal is transitioning, which could lead to conflicts with vehicles coming from other directions.

Overall, recognizing a yellow light means understanding that you should evaluate your ability to stop safely and be prepared for the subsequent red light.
