Provide restrictions and change provisions related to operation of vehicles carrying raw milk

LB 561 modifies Nebraska's vehicle length regulations to create a specific exception for raw milk transport. It adds Section 2(1)(k) to existing law, allowing "overweight raw-milk vehicles" to exceed standard length limits (typically 40-65 feet) when authorized under Section 4 of the bill. This directly affects dairy producers and transport companies moving raw milk, granting them flexibility for vehicle dimensions that would otherwise violate general length restrictions. The provision ensures raw milk vehicles can operate within legal limits without requiring separate permits for length compliance.
