What should be done with turn signals before making a turn?

Answer: C — Signal continuously

Using turn signals continuously before making a turn is crucial for ensuring safety on the road. By signaling your intention well in advance, you alert other drivers and pedestrians of your planned movement, which provides them with the necessary time to react appropriately. Continuous signaling allows for effective communication and helps to create a predictable driving environment. It’s important to signal before beginning your turn to give others adequate notice, and this duration should extend beyond just the moment of turning to reinforce your intention. Other choices might suggest limited signaling or timing that doesn't account for the full situation surrounding the turn, which could lead to misunderstandings or accidents. Continuous signaling is the most responsible approach and adheres to safe driving practices.
