By law how far must a vessel stay from a displayed driver down flag when operating greater than highway speeds?

By law, a vessel must stay at least 100 feet away from a displayed diver-down flag when operating at speeds greater than "no-wake." This distance is crucial for the safety of divers in the water, allowing them a safe area to surface and be retrieved. Violating this distance can lead to penalties and poses a risk to diver safety. Always check local regulations, as they may vary.
