Interstate motor carrier authority sits with the
Federal Motor Carrier Safety Administration (FMCSA)
— the BMC-91 or BMC-91X filing, the MCS-90 endorsement, and the 49 CFR § 387 financial responsibility limits. Kentucky overlays three state agencies on top of that federal layer, and motor carriers operating here interact with each one at different points in the policy life cycle.
State transportation authority and KYU weight-distance tax
The
Kentucky Transportation Cabinet (KYTC)
maintains the state highway and interstate network — I-24, I-64, I-65, I-71, I-75, and I-264 — administers oversize and overweight permits, and handles state-level routing rules through the Division of Motor Carriers. KYTC also administers the KYU weight-distance tax on motor carriers operating vehicles with a combined gross weight of 60,000 pounds or greater on Kentucky highways — a tax-and-registration matter that applies to heavy combinations regardless of domicile.
State insurance regulator
The
Kentucky Department of Insurance (KDOI)
regulates carrier admission, rate filings, policy form approval, and consumer complaint resolution. KDOI also operates a consumer-services function that hears motor carrier complaints about Kentucky admitted carriers. Carrier appetite changes for Kentucky trucking are driven in part by KDOI rate-filing approvals and the broader admitted-market environment.
Workers compensation
The Kentucky Department of Workers Claims, within the Labor Cabinet, administers the workers compensation system, handling claims adjudication, employer compliance, and dispute resolution. Most Kentucky employers with one or more employees carry workers compensation; the classification of leased owner-operators under 1099 arrangements raises questions the audit form does not always resolve cleanly. We work those through at policy bind rather than after a driver injury.
Federal motor carrier overlays
Beyond FMCSA, motor carriers running hazardous materials interact with the Pipeline and Hazardous Materials Safety Administration (PHMSA) on placarding, training, and route restrictions. Motor carriers running specific weight or dimension overages interact with the Federal Highway Administration (FHWA) and KYTC jointly on permit conditions. Drayage and intermodal motor carriers running parcel-feeder operations into UPS Worldport or DHL CVG operate under the Uniform Intermodal Interchange Agreement framework on top of the standard regulatory layer.
