What should you do when approaching a traffic signal that is yellow?

Answer: B — Prepare to stop if it is safe to do so

When approaching a traffic signal that is yellow, it indicates that the signal is about to change to red. The safest and most appropriate action is to prepare to stop if it is safe to do so. This means checking that you are at a safe distance from the intersection, ensuring that other vehicles and pedestrians are clear, and that stopping will not pose a danger to yourself or others. This approach is essential for maintaining traffic safety and preventing accidents. It promotes adherence to traffic laws, which are designed to ensure that drivers respond predictably and safely as traffic signals change. In contrast, actions such as speeding up to cross before the light turns red, ignoring the light, or making abrupt turns can lead to dangerous situations, including collisions.
