The safe-operation knowledge behind the state boater-education card. Master the equipment rules — life-jacket (PFD) types and when they must be worn or carried, fire extinguisher classes and which boats need them, capacity plates and overloading, sound devices and visual distress signals — and the procedures that prevent the classic accidents: fueling and ventilation (run the bilge blower before starting), carbon-monoxide awareness, cold-water immersion and the 1-10-1 rule, anchoring from the bow with proper scope, trailering and launching, weather reading, float plans, and PWC-specific rules. Plus the law: boating under the influence (the federal 0.08 limit), accident-reporting duties, and reckless operation. Where a requirement varies by state the question says so and teaches the federal or most-common rule. Every explanation names the mistake that causes the real accident (anchoring from the stern, gasoline fumes in the bilge, cotton clothing in cold water) and leaves a rule. Original questions from public sources — never items from any state exam or commercial course.
