What does a yellow traffic signal indicate?

Answer: B — You should prepare to stop

A yellow traffic signal indicates that drivers should prepare to stop. This is a crucial warning that the signal is about to change to red, which means that vehicles must yield and stop safely. The yellow light acts as a cautionary measure, allowing motorists to respond appropriately to the upcoming change in traffic control. Drivers approaching a yellow signal should assess their distance from the intersection. If they are far enough away to stop safely without skidding or causing a hazard, they should proceed to do so. The yellow light is not an invitation to accelerate through the intersection; rather, it emphasizes the need for caution and readiness to stop. Recognizing when to stop at a yellow light is essential for maintaining traffic safety and preventing potential accidents. Understanding this signal helps establish clear communication on the road between drivers and reinforces the rules of right-of-way.
