What is the main purpose of using turn signals?

The main purpose of using turn signals is to indicate the driver's intent to other road users. This communication is crucial for maintaining safety on the road, as it allows other drivers, cyclists, and pedestrians to anticipate your actions. By signaling a turn or lane change, you provide vital information that helps prevent accidents and ensures smoother traffic flow.

While using turn signals can make turning easier for the driver, this aspect is secondary to the primary purpose of communicating with others on the road. Signaling to pedestrians indicates only one aspect of road use, as drivers must also inform other vehicles of their intentions. Communication with law enforcement is not typically the primary goal of signaling; rather, it is used to inform fellow road users of a driver's planned maneuvers. Thus, the emphasis on intent and safety makes indicating your plans through turn signals a fundamental practice in responsible driving.
