What is the main purpose of using turn signals while driving?

The main purpose of using turn signals while driving is to alert other drivers of your intent. Signaling your intentions when turning or changing lanes is crucial for maintaining safety on the road. When you use your turn signals, you communicate your intended maneuvers to other road users, helping to prevent accidents and misunderstandings. This communication allows other drivers and pedestrians to anticipate your actions, which is essential for the flow of traffic and overall road safety.

While complying with traffic laws is also important, the primary function of turn signals is communicating intent, which directly contributes to safer driving practices. The idea of showing off vehicle features or improving fuel efficiency is not related to the primary function of turn signals, focusing instead on safety and proper communication on the road.
