What should you do when you approach a traffic signal displaying a steady yellow light?

Answer: B — Stop if it is safe to do so

When you approach a traffic signal displaying a steady yellow light, the appropriate action is to stop if it is safe to do so. A yellow light signals that the light is about to turn red, and drivers should prepare to stop. The intention of the yellow light is to provide a warning that the signal is changing, allowing you to make a decision regarding whether to stop or proceed based on your proximity to the intersection. If you are far enough away from the intersection that you can safely come to a stop before the light turns red, that is the best choice. This helps ensure your safety and the safety of other drivers and pedestrians in the intersection. Additionally, stopping when safe helps prevent the likelihood of accidents that may occur if someone tries to rush through the yellow light as it turns red. In certain situations, such as being too close to the intersection to stop safely, different responses may be considered, but these should be guided by the principle that stopping is generally the safest choice when encountering a yellow light.
