Concrete and solid waste vehicles; increase maximum gross vehicle weight of.

HB 150 increases weight limits for concrete and solid waste transport vehicles in Mississippi. It raises the maximum gross weight to 64,000 pounds for three-axle concrete/solid waste vehicles and 72,000 pounds for four-axle vehicles, while specifying axle distribution limits (e.g., 22,000 pounds per single axle). The bill restricts these vehicles to operating within 50 miles of their home base, requires all wheels to be brake-equipped, and prohibits travel on interstate highways or bridges not rated for the weight. These changes directly affect commercial transport companies handling concrete and solid waste within the state. The law takes effect July 1, 2025.
