What should drivers do when approaching a yellow traffic light?

When drivers encounter a yellow traffic light, it serves as a warning that the light is about to turn red. The appropriate action is to slow down and prepare to stop if it is safe to do so. This means that drivers should assess their speed and the distance to the intersection, considering whether they can stop safely without risking an accident.

Understanding the context of a yellow light is crucial; it is not merely an indication to stop immediately but rather suggests that caution is needed. If a driver is too close to the intersection to stop safely, they may proceed with caution. However, the primary instruction is to reduce speed and be prepared to halt if conditions allow, helping to ensure the safety of everyone on the road. This approach helps prevent sudden stops that might lead to rear-end collisions and maintains overall traffic flow.
