When must you use your turn signal while driving?

Using your turn signal is an essential aspect of safe driving, as it communicates your intentions to other road users. The requirement to activate your turn signal at least 100 feet before a turn or lane change is pivotal because it provides adequate warning to surrounding drivers and pedestrians about your actions. This distance allows others to react properly, reducing the risk of collisions and promoting a more predictable flow of traffic.

Utilizing the turn signal at this distance gives drivers behind you enough time to adjust their speed or position, ensuring a smoother transition and maintaining safety on the road. It is a critical element in demonstrating defensive driving and consideration for others on the road. By signaling well in advance, you aid in preventing misunderstandings or sudden maneuvers from other drivers, which can lead to accidents.

In contrast, turning signals should not be used solely when changing lanes or only when legally required, as this may not provide sufficient notification.
