Mandatory Boater Education
Beginning January 1, 2005, every person born after January 1, 1984, who operates a vessel on Missouri lakes shall possess, on the vessel, a boating safety identification card issued by the Missouri State Water Patrol (along with a valid photo ID). If you fall into the required age range and are a resident of Missouri, you will need to obtain a Missouri certification card. If you are a resident of Missouri but do not fall into the age range, you are not required to have the Missouri card. Remember, a vessel is every motorboat and motorized watercraft including a personal watercraft.
Any person convicted of Boating While Intoxicated, Reckless and Negligent Operation, Failing to Stop on Signal of Water Patrol, or Leaving the Scene of a Vessel Accident shall enroll in and successfully complete, at his or her own expense, a boating safety education course. They must then file with the court proof of successful completion of such course and submit a certified copy to the Missouri State Water Patrol. The convicted person cannot operate a vessel until such filing is made.
