The bill aims to restrict enforcement officers from boarding or stopping vessels without probable cause in Mississippi. It emphasizes the need for probable cause before such actions can be taken and prohibits vessel stops or boarding solely for safety or marine sanitation equipment inspections. The bill also outlines the procedures and consequences related to chemical tests and arrests for operating a watercraft under the influence of alcohol. If enacted, this bill will impact the authority and procedures of enforcement officers in conducting vessel stops and inspections, as well as the regulations regarding chemical tests for alcohol content in individuals operating watercraft.
