Using turn signals is essential for communicating your intentions to other drivers. When you signal your upcoming maneuvers, such as turning or changing lanes, you provide crucial information that allows other drivers to anticipate your actions. This improves road safety by reducing the likelihood of misunderstandings and collisions.

While signaling a lane change and alerting pedestrians are important aspects of safe driving, they are specific applications of the broader purpose of turn signals, which is to ensure clear communication on the road. Similarly, signaling a legal stop is another specific scenario where turn signals may be used, but again, it falls under the umbrella of communication between drivers. Overall, the primary function of turn signals is to enhance safety through effective communication with everyone on the roadway.
