According to Arizona law, during what hours is it illegal to operate a personal watercraft unless it is equipped with proper navigation lights?

Operating a personal watercraft is regulated under Arizona law to ensure safety and visibility on the water. It is illegal to operate a personal watercraft between sunset and sunrise unless it is equipped with the proper navigation lights. This regulation is put in place because visibility conditions during nighttime can be significantly reduced, posing a higher risk for accidents. Navigation lights are essential for making the vessel visible to other watercraft and for the operator to see the surrounding environment.

Understanding this, the correct answer emphasizes the importance of being equipped for safe operations during low-light conditions. During the day, there is usually ample natural light, which reduces the need for additional navigation aids. Hence, there's no requirement for navigation lights from sunrise to sunset. Operating a watercraft in inclement weather may also pose dangers, but the law explicitly addresses nighttime operations concerning visibility. Therefore, the correct understanding of operating regulations emphasizes safe practices during hours of reduced visibility.
