Where must you attach an engine shutoff line when operating a PWC?

When operating a personal watercraft (PWC), the engine shutoff line, often referred to as the lanyard or kill switch, must be securely attached to the operator's wrist or life jacket. This ensures that if the operator falls off or is ejected from the PWC, the engine will shut off immediately, preventing potential accidents and allowing the operator to reboard safely. Always verify that the shutoff line is functional before heading out on the water.
