What is the purpose of using turn signals before changing lanes?

Using turn signals before changing lanes is essential for safety and communication on the road. The primary purpose of turn signals is to alert other drivers of your intention to change directions. This helps create awareness among surrounding vehicles, allowing them to anticipate your actions and adjust accordingly, which reduces the risk of collisions and enhances overall traffic flow.

Effective signaling is a fundamental aspect of responsible driving, as it fosters cooperation and predictability among drivers. When drivers see a signal indicating a lane change, they can gauge whether to adjust their speed or position to maintain safe distances, thereby supporting a smoother driving experience.
