What action should a driver take when seeing the traffic light turn from green to yellow?

When a driver observes the traffic light change from green to yellow, the appropriate response is to prepare to stop if it's safe to do so. The yellow light serves as a warning that the light is about to turn red, indicating that drivers should clear the intersection. At this moment, it's crucial to assess the traffic conditions and determine if stopping is a safe option.

If a driver can safely come to a stop before reaching the intersection, it’s best to do so to ensure adherence to traffic laws and to prevent potential accidents. This preventive measure not only keeps the flow of traffic orderly but also upholds safety for all road users, including pedestrians and other vehicles.

Driving straight through the intersection at the onset of a yellow light can lead to dangerous situations, including running a red light, which could result in serious consequences. Additionally, accelerating to beat the light can cause conflicts with other vehicles that may also be reacting to the changing traffic signal, further increasing the risk of accidents. Therefore, being vigilant and prepared to stop is the best course of action when facing a yellow traffic light.
