When you see a stopped motorist, law enforcement officer, emergency vehicle or other utility truck on the shoulder, you must?

Answer: B — Move over to the left lane when it's available

When approaching a stopped motorist, law enforcement officer, emergency vehicle, or utility truck on the shoulder, moving over to the left lane when it's available is the safest and most appropriate action. This law is designed to protect both the individuals on the side of the road and the drivers passing by. By switching lanes, you are creating a buffer zone that reduces the risk of collision and ensures the safety of those who are potentially in harm's way while attending to their vehicle or working. This practice is often referred to as the "Move Over" law, which emphasizes the importance of being attentive and considerate when you encounter stationary vehicles. This response not only enhances safety but also demonstrates a responsible driving behavior that aids in reducing road hazards. While slowing down or stopping could provide some level of caution, it does not offer the same protective benefit to roadside workers and may even lead to secondary accidents. Therefore, maintaining the awareness to safely change lanes when possible is paramount.
