This bill establishes new criminal offenses specifically for boat operators in South Dakota, introducing penalties for negligent behavior while under the influence of alcohol, drugs, or other substances. It creates a new offense called "watercraft homicide," which is classified as a Class 3 felony for individuals who operate a boat negligently and cause the death of another person, including an unborn child. Additionally, the bill introduces "watercraft battery," a Class 4 felony, for those who cause serious bodily injury to another person, also including unborn children, under similar circumstances.

Furthermore, the bill mandates that any boat operator involved in an accident resulting in injury or death must immediately stop and comply with specific legal provisions. Failure to do so will result in a Class 6 felony charge. These new sections aim to enhance accountability and safety on South Dakota's waterways by imposing stricter penalties for negligent and reckless behavior among boat operators.
