Bill > HB1375

This bill adds a new section to Missouri state law that allows vehicles transporting construction materials or raw materials to exceed standard weight limits by up to 10 percent under specific conditions. The bill defines key terms such as "construction materials" (which includes asphalt, concrete, and aggregates) and "raw materials" (like sand, gravel, and rock). Vehicles can carry this additional weight when transporting materials from production sites to construction projects, but only if the vehicle is properly maintained and does not exceed the manufacturer's specified gross vehicle weight rating. Importantly, this weight exemption does not apply to the interstate highway system, and vehicles operating at the increased weight are prohibited from traveling on bridges or structures with lower posted weight limits. Additionally, such vehicles must not exceed 30 miles per hour when crossing bridges or structures with weight restrictions. The goal appears to be providing some flexibility for construction and materials transportation while maintaining safety standards for road and bridge infrastructure.
