When would a driver need to use turn signals?

Answer: B — When changing lanes or turning

Utilizing turn signals is essential for safe driving, particularly when changing lanes or turning. This action communicates a driver's intentions to others on the road, including both vehicles and pedestrians. By signaling, drivers help prevent accidents that can occur from sudden lane changes or turns without warning. It promotes a predictable traffic flow and enhances overall road safety. When a driver indicates their intention to turn or change lanes, it allows other road users to prepare appropriately, which is vital in maintaining a safe distance and avoiding potential collisions. Turn signals should be used consistently whenever a change in direction is planned, regardless of the traffic conditions, ensuring clear communication among all road users.
