Final answer:
In Minnesota, diving is not permitted from one hour after sunset to sunrise unless the diver has a visible diver's light. This regulation aims to enhance safety and visibility for divers in low light conditions.
Step-by-step explanation:
In Minnesota, diving is not permitted from one hour after sunset to sunrise, unless the diver has in his/her possession a diver's light that is visible for at least 150 feet above the water.
This regulation is in place to ensure the safety of divers and to make them more visible to others in the area. By requiring a visible light, it helps prevent accidents and collisions, especially in low light conditions.
