What is the purpose of using turn signals while driving?

Using turn signals while driving serves multiple essential purposes that enhance road safety and effective communication among drivers. When a driver uses turn signals, they are primarily communicating their intentions to other road users. This communication helps prevent accidents by clearly indicating to nearby drivers and pedestrians what to expect next, whether it's a lane change, a turn, or any other maneuver.

Indicating lane changes is a critical function of turn signals. They provide a visual cue that informs other drivers of your plans to change lanes, allowing them to adjust their driving accordingly.

Additionally, turn signals act as a warning system. By signaling, a driver can alert others to potential movements or changes in traffic flow, thereby reducing confusion and improving overall road safety.

The comprehensive nature of these functions explains why the correct answer encompasses all the choices provided. Each aspect—indicating lane changes, warning other drivers, and communicating intentions—plays an integral role in safe driving practices.
