At what distance should you signal before making a turn?

Signal at least 100 feet before making a turn to provide adequate notification to other drivers, pedestrians, and cyclists of your intended maneuver. This distance allows others to interpret your intention and adjust their speed or position accordingly, contributing to overall road safety. The 100-foot guideline is specifically designed to give drivers sufficient time to respond, reducing the likelihood of accidents during lane changes or turns. By signaling well in advance, you promote a smoother flow of traffic, as other drivers can prepare to give you the space you need to complete the turn safely.
