What is the purpose of using turn signals while driving?

Using turn signals while driving primarily serves to inform other drivers of your intended maneuvers. When you activate your turn signal, it signals to surrounding vehicles that you plan to change lanes, make a turn, or otherwise maneuver on the road. This communication is essential for maintaining safety and preventing accidents, as it allows other road users to anticipate your actions and respond appropriately.

While turn signals can have an indirect effect on pedestrian awareness and might contribute to overall traffic flow, their primary function is to convey your driving intentions to other motorists. This aids in keeping traffic predictable and organized, enhancing everyone's safety on the road through effective communication.
