What is a key benefit of using turn signals?

Using turn signals is essential for safe driving, as they serve the primary purpose of alerting other drivers of your intended movements. When a driver activates their turn signal, it communicates to others on the road what direction they plan to go, whether it's a turn or a lane change. This communication helps prevent accidents by allowing those around you to anticipate your actions, contributing to a smoother flow of traffic.

The correct answer highlights the role of turn signals in enhancing safety and facilitating driver awareness, thereby reducing the likelihood of collisions. While the other options touch on unrelated aspects of driving, such as speed, vehicle performance, and fuel efficiency, they do not align with the primary function of turn signals in promoting safe and informed driving practices.
