When using arm signals, how far in advance should you signal before slowing down or making a turn?

Using arm signals is an important aspect of communicating your intentions as a driver, especially when turning or slowing down. Signaling at least 100 feet in advance provides ample warning to other drivers around you. This distance allows time for other road users to recognize your intent and react accordingly, helping to maintain safety on the road.

By giving a clear signal well in advance, you help prevent confusion and reduce the risk of accidents. It ensures that following vehicles can adjust their speed or position safely, and it also alerts pedestrians of your intended actions. Therefore, the requirement to signal at least 100 feet before performing maneuvers like turning or slowing down enhances overall road safety and facilitates smooth traffic flow.
