What is the main reason for using turn signals while driving?

The primary purpose of using turn signals while driving is to alert other drivers of your intentions. Turn signals serve as a vital communication tool on the road, allowing you to convey your planned maneuvers, such as turning, merging, or changing lanes. By signaling, you help ensure that other drivers are aware of your actions, which promotes safety and reduces the likelihood of collisions.

This practice is essential in maintaining an orderly flow of traffic, as it provides critical information to other drivers, cyclists, and pedestrians. When everyone uses turn signals properly, it fosters a safer driving environment for all road users. While signaling may also meet legal requirements, the core function remains focused on communication, making it clear and understandable to others what you intend to do on the road.
