How far in advance must you signal before making a turn?

Signaling at least 100 feet before making a turn is important for ensuring safety on the road. This distance gives other drivers, cyclists, and pedestrians enough time to recognize your intention to turn and adjust their own movements accordingly. It helps create a predictable traffic environment where everyone is aware of what others will do next, thereby reducing the chance of accidents.

The 100-foot distance is also consistent with the recommended practices for signaling turns in various driving manuals and regulations. This allows for effective communication with other road users, enhancing overall traffic flow and safety.

Shorter distances may not provide sufficient time for those around you to react appropriately when you decide to turn. For instance, signaling just 50 or 75 feet in advance may be too close, particularly at higher speeds, leading to confusion or unexpected maneuvers by other drivers. By signaling at the correct distance, you contribute to a safer driving experience for everyone on the road.
