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 and those drawn by them, such as off-road vehicles and motorcycles, 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.

Certain exceptions are included in the bill, allowing for the operation of motor vehicles 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 the vehicle is used by a utility providing electric service. The act is set to take effect on October 1, 2025.
