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

Using turn signals when changing lanes serves the critical purpose of showing your intention to other drivers. This communication is vital for maintaining safety on the road, as it allows other drivers to anticipate your actions, maintain safe distances, and respond appropriately. By signaling your intention to change lanes, you help prevent collisions by ensuring that other vehicles are aware of your movements.

Although complying with vehicle regulations is important, signaling primarily focuses on effective communication rather than just following the law. The use of turn signals is not meant to confuse other drivers; rather, it aims to provide clarity and enhance overall roadway safety. Indicating speed is also unrelated to the primary function of turn signals, which is focused exclusively on conveying intentions about lane changes or turns.
