When should a driver use their turn signals?

Answer: C — When turning or changing lanes

Using turn signals is essential for communicating your intentions to other road users. The correct answer emphasizes that drivers should signal when turning or changing lanes. This is important because it allows other drivers, cyclists, and pedestrians to anticipate your actions, leading to safer driving conditions. Proper signaling is a key component of defensive driving practices and helps prevent misunderstandings or accidents on the road. While signaling may seem less necessary in specific situations like solitary driving or when entering a roundabout or merging onto a highway, it is still vital. Signaling at all times when making maneuvers—such as turns or lane changes—ensures clear communication with others and promotes overall road safety.
