What is one of the main functions of turn signals?

Turn signals are primarily designed to indicate your intended direction to other drivers on the road. When a driver activates their turn signal, it communicates to surrounding vehicles that they plan to make a turn or change lanes. This is crucial for safety, as it allows other road users to anticipate and react accordingly to your maneuvers, helping to prevent collisions and ensuring smoother traffic flow.

The use of turn signals fosters clearer communication between drivers, which is essential for maintaining order on the road. By signaling before making a turn or lane change, you give others a chance to adjust their speed or position, reducing the risk of accidents. This signaling becomes even more important in busy traffic conditions or at intersections where multiple vehicles converge.

While other functions on the road, such as alerting pedestrians or warning of hazards, are important as well, those functions do not specifically pertain to the role of turn signals. Their primary and most critical function remains the indication of intended directional changes to facilitate safe driving practices.
