When should you always use your turn signals?

Answer: B — When changing lanes

Using turn signals is a critical aspect of safe driving, and they should always be utilized when changing lanes. This action communicates your intentions to other drivers, helping to prevent accidents and ensuring a smoother flow of traffic. When you indicate a lane change, you give other road users time to react appropriately, whether that means adjusting their speed or position on the road. In other scenarios, like approaching an intersection, even though it can be beneficial to signal your intentions to turn, the requirement is specific to lane changes, making it crucial to remember to signal whenever you are about to switch lanes. The other options present situations where signaling is less relevant or not mandatory, which emphasizes the importance of using turn signals specifically when maneuvering through lanes.
