Relating to: weight limits for vehicles transporting grain, feed, or commercial fertilizer. (FE)

AB 679 creates a new permit system for trucks carrying grain, feed, or commercial fertilizer that exceed standard weight limits. It allows vehicles with 6 or more axles to operate at up to 91,000 pounds gross weight on state highways, provided they meet axle weight distribution rules and follow department-specified routes. The bill directly affects agricultural haulers and trucking companies transporting these materials, requiring a $325 permit for such operations. Permits are invalid on interstate highways (except as permitted by federal law) and may be suspended during spring thaw conditions. This bill does not change base weight limits but establishes a regulated pathway for heavier agricultural transport.
