What should a driver do when approaching an intersection and seeing the traffic light turn from green to yellow?

When approaching an intersection and the traffic light changes from green to yellow, the appropriate action is to stop at the line if it is safe to do so. The yellow light serves as a warning that the light is about to turn red, signaling drivers to either clear the intersection safely if they are already within it or stop before the intersection if they can do so without risking a rear-end collision.

Stopping at the line helps prevent potential accidents caused by trying to speed through the intersection when the light is changing. It also ensures compliance with traffic laws designed to maintain safety on the road. This behavior reinforces the principle of traffic signal adherence and promotes safer driving practices, particularly in busy intersection environments where unexpected movements can lead to dangerous situations.

Choosing to speed up to cross before the light turns red undermines traffic signals' purpose and could lead to complications or crashes. Preparing to turn left is only relevant if there is a left-turn lane and other considerations are accounted for. Proceeding without stopping may not allow adequate time to assess conditions ahead and could result in running a red light, which is illegal and hazardous.
