What is the primary purpose of using turn signals?

The primary purpose of using turn signals is to communicate your intentions to other drivers. This is crucial for road safety, as it allows other motorists and users of the road to anticipate your movements—whether you are turning, changing lanes, or stopping. Effective use of turn signals helps to prevent accidents by providing essential information about your intended maneuvers, fostering a safer driving environment.

While signaling only for a lane change, addressing pedestrians, or alerting police officers are important factors related to driver communication, the most comprehensive and fundamental role of turn signals is to inform all road users of your actions, ensuring smooth traffic flow and increased safety for everyone involved.
