At what distance should you begin using your turn signal before making a turn?

Using your turn signal at least 100 feet before making a turn is essential for ensuring safety on the road. This distance provides adequate warning to drivers behind you and those at intersections of your intention to change direction, allowing them to react appropriately. The 100-foot rule strikes a balance between giving enough notice without being excessive. It is long enough to alert other drivers, including those who might be approaching from behind or at an intersection, which helps prevent potential accidents.

This distance is particularly important in urban areas where traffic can be more congested and where other vehicles, cyclists, and pedestrians are present. By signaling in advance, you contribute to clearer communication on the road and promote safer driving practices.

While other distances, such as 50 or 200 feet, may be seen elsewhere, the 100-foot guideline is commonly accepted as a standard that effectively enhances safety while maintaining traffic flow.
