Bill
HB 258
HB 258 strengthens Kentucky’s rules to allow higher weights and dimensions for transporting milk and farm goods and establishes a permit system to govern these loads.
HB 258 (2026RS) — Summary of Transportation of Milk Provisions
Jurisdiction: Kentucky
Committee: Agriculture (H) / final action in Senate
Sponsors: Multiple House sponsors including Chad Aull, Mark Hart, Sarah Stalker, Myron Dossett, Beverly Chester-Burton, Steve Bratcher, J.T. Payne
Purpose and intent
- To regulate and expand permitting and weight/dimension allowances for transporting milk and other agricultural products, with specific emphasis on fluid milk products originating from farms to first market. The measure adjusts existing Kentucky statutes governing highway weight and size limits, special permits, and enforcement to accommodate agricultural product transport, including fluid milk, on the state-maintained system and certain designated routes.
Key provisions and changes
1) Height, length, and weight allowances on state-maintained highways (KRS 189.222)
- Allows the Transportation Cabinet Secretary to issue official orders increasing maximums for height, length, and weight on designated highways if justified by highway strength, safety, durability, and lack of unreasonable risk, with classifications by road type.
- Standard maximums (subject to federal law) include:
- Height: 14 feet for vehicles transporting motor vehicles; 13.5 feet for all other vehicles.
- Length: Semitrailers 53 feet; trailers 28 feet; motor trucks 45 feet (with up to two trailers per truck-tractor).
- Weight: 20,000 pounds per single axle; 34,000 pounds for two-axle tandems; 48,000 pounds for three-axle groups; total gross up to 80,000 pounds.
- Per-axle tolerances: Generally up to 5% per axle (except as otherwise provided).
- Limited interstate/ designated safe routes: Most heavy combinations restricted to interstate or designated segments, with a 102-inch wide or less vehicle, up to 80,000 pounds, allowed to travel up to 15 miles from an interstate/parkway exit on non-interstate state highways.
- Special case allowances: Certain categories (e.g., fluid milk products in some contexts) may be treated separately under permits.
2) Permit framework for overweight/overdimensional loads (KRS 189.270; 189.2717)
- Department may issue single-trip or annual permits for nondivisible loads that exceed standard limits, with conditions to preserve safety and highway integrity.
- Permit limits (subject to subsections) commonly allow up to:
- 16 feet width; 120 feet length; 13.5 feet height; up to 160,000 pounds gross (with milk-specific exceptions capping certain permits at 100,000 pounds for fluid milk transport).
- For fluid milk, permits may specify a weight cap of 100,000 pounds when transporting milk products under these overweight permits (not exceeding federal or bridge limits).
- Fees: Administrative regulations will set permit fees; annual permits for farm equipment have specified fee tiers ($80 for <=14 feet width; $150 for >14 feet width).
- Route and escort requirements: Permits may limit routes, require escort vehicles, safety markings, and other safety restrictions; operators must provide route-clearance measurements and may be responsible for compliance risk (bare licensee concept).
- Bonding: Applicants may be required to post a surety bond to indemnify state/ counties against highway damage.
- Parade floats: Float permits follow similar rules, with waivers for Commonwealth-parade use.
3) Definitions and broader scope (KRS 189.010; other sections)
- Expanded or reaffirmed definitions for motor trucks, trailers, semitrailers, engineered vehicles, and related terms to align with the amended weight/dimension framework.
- Clarifications around safety zones, roadways, intersections, and related terminology to ensure consistent enforcement and application of the new allowances.
Who is affected
- Trucking/operators transporting milk, agricultural products, and other nondivisible loads may benefit from higher weight/dimensions or streamlined permitting when transporting fluid milk from farm to first market.
- Carriers engaged in farm-to-market and agricultural supply transport may use the permit framework to plan routes with fewer restrictions, subject to safety conditions.
- Local governments and law enforcement in Kentucky will implement the updated regulations via administrative rules and permit provisions.
Timeline and procedural notes
- The bill provides authority for the Transportation Cabinet to issue official orders adjusting limits (subject to federal law and highway safety considerations).
- Administrative regulations under KRS Chapter 13A will be developed to set permit fees and detailed requirements (escort, safety markings, routes, etc.).
- Enactment timeline aligns with standard Kentucky legislative process; the action history shows passage in the House and Senate committee routing, with a House Committee Substitute approved in February 2026.
Bottom line
HB 258 modernizes and modestly expands Kentucky’s regulatory framework for transporting milk and other agricultural goods by refining height/length/weight allowances, creating a structured permit system for overweight/nondivisible loads, and clarifying enforcement and safety requirements to support farm-to-market logistics while guarding highway safety and federal funding eligibility.
