The bill, designated as SB171, aims to regulate the operation of motor vehicles on land submerged beneath navigable and non-navigable waters in Alabama. It defines "motor vehicle" to include self-propelled vehicles such as off-road vehicles, motorcycles, and motor scooters, while explicitly excluding vessels or watercraft. The bill prohibits individuals from operating motor vehicles on submerged lands and within the natural boundaries of waterways, establishing a tiered penalty system for violations: a Class C misdemeanor for the first offense, a Class B misdemeanor for the second, and a Class A misdemeanor for any subsequent violations.

Additionally, the bill outlines specific exemptions to these prohibitions, allowing motor vehicle operation on submerged lands if the operator owns the land or has permission, if authorized in writing by the Director of the State Lands Division, or if conducted by utilities providing electric service. The act is set to take effect on October 1, 2025.
