How many feet in advance should a driver signal before making a turn?

A driver should signal at least 100 feet in advance of making a turn to ensure that other road users have adequate notice of the change in direction. This distance allows enough time for other drivers and pedestrians to react accordingly, thereby enhancing safety on the road. Signaling too late can lead to confusion and increase the risk of accidents, as other drivers may not anticipate the movement and could collide with the signaling vehicle. Following this guideline contributes to better communication on the roadway, ensuring that all users are informed of a driver's intentions well ahead of time.
