What is the purpose of using turn signals while driving?

Using turn signals while driving serves the essential purpose of communicating your intentions to other drivers on the road. When you activate your turn signal before changing lanes or making a turn, you are providing a visual cue that helps other drivers anticipate your movements. This communication is critical for maintaining safety and preventing accidents, as it allows others to adjust their speed or position based on your intended actions.

In contrast, alerting drivers of your speed or confusing them are not the functions of turn signals. Turn signals also are not intended for signaling pedestrians to cross; rather, they are meant for vehicle-to-vehicle communication. Understanding the purpose of turn signals reinforces the importance of safe driving habits and adherence to road rules that prioritize effective communication among all road users.
