What is the main reason to use turn signals while driving?

Using turn signals while driving primarily serves to indicate a change in direction to other drivers. This practice enhances safety on the road by ensuring that other motorists are aware of your intentions to turn or change lanes. When drivers use turn signals, they communicate their planned maneuvers, which helps prevent collisions caused by sudden or unexpected movements. This communication facilitates smoother traffic flow and reduces confusion among road users, making driving safer for everyone.

While notifying pedestrians is an important aspect, the primary function of turn signals is geared towards interacting with other vehicles. Keeping the driver focused or discussing fuel savings, although relevant to driving habits, do not encapsulate the primary purpose of turn signals, which is essential for effective road communication.
