What is the main purpose of using turn signals while driving?

The main purpose of using turn signals while driving is to inform other drivers of your intentions. When a driver signals to turn or change lanes, it communicates to others on the road what they plan to do before they actually execute that maneuver. This advance notice helps to enhance safety by allowing other drivers to prepare and adjust their actions accordingly, thus reducing the risk of accidents. Effective use of turn signals keeps traffic flowing smoothly and helps maintain predictability on the road, which is essential for safe driving.
