What is the main reason for using turn signals?

Using turn signals is essential for alerting other drivers to your intended movements on the road. When you signal before turning or changing lanes, you communicate your intentions to those around you, which helps prevent accidents and ensures a smoother flow of traffic. Signaling is a key aspect of safe driving practices; it allows other road users to anticipate your actions and react accordingly, fostering a safer driving environment for everyone.

The other options do not align with the primary purpose of turn signals. For instance, using turn signals is not about showing off your vehicle's features, notifying law enforcement, or indicating a malfunction. Their primary role is to convey your driving intentions to enhance safety and coordination among all road participants.
