What action should a driver take when a traffic signal changes to yellow?

When a traffic signal changes to yellow, the appropriate action for a driver is to stop if it is safe to do so. The yellow light signals that the light is about to change to red, indicating that vehicles should prepare to stop unless they are already too close to the intersection to do so safely.

Stopping is important for several reasons: it helps prevent accidents that can occur from vehicles trying to rush through the intersection on a yellow light, promoting safer driving behavior. Additionally, adhering to this practice helps maintain order and predictability at intersections, which is crucial for the flow of traffic.

In situations where stopping safely is not an option—such as when a driver is too close to the intersection—the driver must exercise caution and be prepared to proceed as safely as possible while avoiding sudden maneuvers that could cause a collision. However, the primary response to a yellow light is to stop when it can be done safely, aligning with traffic regulations and ensuring a safer driving environment.
