What is the required minimum distance to activate your turn signal before changing lanes?

The minimum distance required to activate your turn signal before changing lanes is 100 feet. This distance is important for ensuring that other drivers are aware of your intentions to change lanes, allowing them to react appropriately and maintain safety on the road. Activating your turn signal at this distance provides ample warning to surrounding vehicles, which is critical in preventing accidents. It enables drivers in adjacent lanes enough time to notice the signal and respond by adjusting their speed or position if necessary. This regulation is a part of safe driving practices, emphasizing the need for clear communication among road users.
