Why is it important to use turn signals when making lane changes?

Using turn signals when making lane changes is crucial for safety because they serve as a means of communication with other drivers on the road. By signaling your intentions, you alert drivers nearby that you plan to change lanes. This allows them to anticipate your movements and make appropriate adjustments, thereby reducing the risk of collisions or misunderstandings. Proper signaling demonstrates a commitment to safe driving practices and fosters a cooperative driving environment.

In contrast, using turn signals to indicate parking intentions, showing curiosity about other vehicles, or creating visual distractions would not contribute positively to road safety or effective communication. Indicating parking intentions is not relevant when changing lanes, and curiosity or distractions can confuse other drivers, leading to potential hazards. Therefore, the use of turn signals primarily focuses on ensuring clarity and enhancing safety during lane changes.
