Which of the following actions requires you to signal your intention to turn?

Answer: B — Changing lanes and turning at intersections

Signaling your intention to turn is crucial for safe driving, as it communicates your actions to other drivers and pedestrians, allowing them to anticipate your movements. The correct action that requires signaling is when you are changing lanes and turning at intersections. When changing lanes, signaling indicates to other drivers that you are about to merge into their lane, helping to prevent accidents. Additionally, when approaching an intersection to turn, signaling informs others of your intention to continue or change direction. This combination of actions is central to maintaining order and safety on the road. While turning at intersections and entering roundabouts also necessitate signaling, the correct answer encompasses both changing lanes and turning, emphasizing that you need to make your intentions clear in multiple driving scenarios. This awareness and communication are essential for the safety of all road users.
