What should you do when you encounter a yellow traffic signal?

When you encounter a yellow traffic signal, preparing to stop if it is safe to do so is the correct action. A yellow signal indicates that the traffic light is about to change to red, which means that vehicles should be prepared to stop. The intent of the yellow light is to give drivers a warning that they need to make decisions regarding stopping or proceeding through the intersection.

If stopping is safe—meaning you are not too close to the intersection where sudden braking could lead to a rear-end collision—then it is crucial to reduce speed and stop. This helps prevent running a red light, which can lead to dangerous accidents.

In contrast, speeding up to clear the intersection can create hazardous situations for both the driver and other road users, as it increases the likelihood of entering the intersection after the light has turned red. Continuing to drive at the same speed after seeing a yellow light disregards the warning that a stop may soon be required, putting the driver at risk of a violation or collision. Simply assuming the light will turn red shortly without taking prudent action also neglects the need for careful driving in response to traffic signals.
