What is the primary purpose of signaling before a turn?

The primary purpose of signaling before a turn is to warn other drivers of your intentions. When a driver uses their turn signal, it communicates to other road users that they plan to change direction, whether by turning or merging into another lane. This is crucial for maintaining safety on the road, as it allows other drivers to anticipate the movement and adjust their own driving accordingly.

Effective signaling improves the flow of traffic and helps to avoid misunderstandings between drivers, which can otherwise lead to confusion or accidents. While other options relate to driving behavior, the fundamental role of signaling is to inform others about your intended actions to facilitate safer navigation on the road.
