What is the purpose of using turn signals while driving?

Using turn signals while driving serves a crucial function in enhancing road safety and facilitating smooth traffic flow. The primary purpose is to communicate your intentions to other road users, including drivers, pedestrians, and cyclists. When you signal, you are informing others of your next move—whether you intend to change lanes, turn at an intersection, or merge into traffic. This communication helps prevent misunderstandings and accidents by allowing other road users to anticipate your actions and adjust their own behavior accordingly.

Effective communication through signaling is significant because it contributes to the overall predictability of traffic. When drivers give clear signals about their intentions, it creates a safer driving environment where everyone can respond appropriately to the actions of others. This practice fosters courteous driving and minimizes the risks associated with sudden lane changes or unannounced turns.

While complying with traffic laws is an important aspect of using turn signals, that is only one part of their function. The emphasis on communication underscores the critical role that signaling plays in ensuring everyone's safety on the road.
