What action should a driver take when a traffic signal turns yellow?

When a traffic signal turns yellow, it serves as a warning that the light is about to change to red. The appropriate action for a driver is to prepare to stop if it is safe to do so. This means assessing the situation: if you are at a distance from the intersection where you can safely stop before reaching it, then you should do so. This action helps prevent potential accidents that may occur if a driver attempts to continue through the intersection once the light has turned red.

It's important to maintain awareness of the vehicles around you; if stopping would create a hazard (such as being rear-ended), then it might be necessary to proceed through the intersection carefully. However, the primary guidance is to be ready to stop when the light changes from green to yellow, ensuring that you comply with traffic laws and maintain safety for yourself and others on the road.
