What does a 'Wrong Way' sign indicate?

Answer: C — You must turn around

A 'Wrong Way' sign is a crucial safety indicator that alerts drivers they are traveling against the intended flow of traffic. When you see this sign, it means you are on a path that is not meant for vehicles moving in your current direction, often indicating you are driving towards oncoming traffic—not only a violation of traffic rules but a significant hazard that could result in serious accidents. Recognizing this sign means immediate action is required: you must turn around to avoid a collision and ensure your safety and the safety of others on the road. This understanding is vital for maintaining proper traffic flow and minimizing the risk of accidents on one-way streets or other areas where directionality is strictly enforced.
