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

Using turn signals while driving serves primarily to notify other drivers of your actions. This communication is essential for maintaining safety on the road, as it informs other road users of your intentions to turn or change lanes. By signaling your actions in advance, you allow others to adjust their driving accordingly, helping prevent accidents and misunderstandings.

While keeping vehicle lights functioning is important for overall vehicle maintenance, it does not directly relate to the specific role of turn signals. Parking accuracy is certainly enhanced by proper signaling, but that is a secondary benefit rather than the primary purpose. Similarly, signaling to pedestrians is a component of road awareness, but turn signals are mainly intended for other drivers, making it crucial for safe driving practices.
