Why is it important to use turn signals when changing lanes?

Using turn signals when changing lanes is crucial because it communicates your intentions to other drivers on the road. This communication enhances safety by alerting nearby vehicles that you plan to move into a different lane. When other drivers are aware of your intentions, they can take necessary actions, such as adjusting their speed or position, to help prevent collisions. Proper use of turn signals helps create a more predictable driving environment, contributing to overall road safety for all users, including pedestrians and cyclists.
