What Commercial Auto Insurance Is Required in Kentucky?

Every registered commercial vehicle in Kentucky must carry liability insurance under KRS 304.39-090. Base minimums align with the state's personal auto floor, as detailed in commercial auto insurance requirements:

  • $25,000 for bodily injury or death of one person per accident
  • $50,000 for bodily injury or death of two or more people per accident
  • $25,000 for property damage per accident

Kentucky's 25/50/25 limits cover standard business vehicles making local deliveries, running errands or traveling between job sites. Businesses that transport passengers for hire, haul regulated cargo or operate vehicles over 10,001 pounds GVWR must carry higher coverage under KRS 281.655 or federal FMCSA rules detailed below.

KENTUCKY IS A CHOICE NO-FAULT STATE

Kentucky's no-fault system enrolls every commercial auto policy in PIP coverage unless the policyholder signs a written rejection. Under PIP, each party's own insurer pays medical expenses and lost wages up to the policy limit regardless of fault. Rejecting PIP only strips coverage from listed drivers and employees. Guest passengers and pedestrians stay covered by law.

WHEN DOES FEDERAL LAW APPLY OVER KENTUCKY LAW?

Federal FMCSA requirements take over when Kentucky vehicles carry cargo or passengers across state lines, or when a Kentucky-only leg is part of a larger interstate shipment chain. The federal threshold starts at 10,001 pounds GVWR for general freight, but hazmat triggers federal jurisdiction at any weight. A single Louisville-to-Cincinnati load shifts that vehicle to FMCSA minimums for the trip, even if the truck normally stays in state. Businesses operating entirely within Kentucky stay under KRS 281.655 tiers; confirm which rules apply through the Kentucky Transportation Cabinet, FMCSA insurance filing requirements, and a licensed insurance professional.

Kentucky Commercial Auto Insurance Requirement Exemptions

Kentucky keeps its commercial auto exemptions narrow compared to states with broad agricultural or remote-area carve-outs. Exemptions under KRS 304.39-090 and the Kentucky Department of Vehicle Regulation apply only when a vehicle stays off public roads and outside commercial activity.

Vehicle used only for personal purposes
Personal auto insurance rules
Farm vehicles not operated on public roads
May not require liability coverage under road-use laws
Off-road equipment not driven on public highways
Not subject to on-road insurance mandates
Government vehicles under authorized self-insurance
Government self-insurance statutes
Vehicles not registered for road use (yard-only, private property)
No road-use liability requirement
Active-duty military with out-of-state insurance
May use out-of-state insurer to title and register in Kentucky

Kentucky's commercial auto exemptions end the moment a vehicle touches a public road for business purposes. A flatbed hauling hay between two private fields that takes a quarter-mile of state highway loses the exemption for that trip and needs at least 25/50/25 coverage. Contact your county clerk's office or the Division of Motor Vehicle Licensing if you're unsure whether a vehicle qualifies.

Kentucky Commercial Auto Insurance Alternatives

Kentucky permits exactly one alternative to the standard 25/50/25 split limits under KRS 304.39-090.

  • Combined single limit (CSL) policy: Kentucky accepts a CSL of at least $60,000 in place of 25/50/25, but the policy must include basic reparations benefits (PIP) unless the vehicle is a motorcycle. This option covers the base tier only and isn't available to passenger carriers, property carriers over 10,001 pounds, or hazmat operations that must meet higher KRS 281.655 limits.

Special Kentucky Commercial Auto Insurance Coverage Circumstances

Four situations in Kentucky create coverage obligations or gaps outside the standard requirement tiers.

    Leased Commercial Vehicles

    Kentucky lease agreements almost always require collision and comprehensive coverage on top of state liability minimums, plus limits well above 25/50/25, often $1 million CSL. Compare your policy line by line against the lease's insurance clause before renewal, because a gap between the two can trigger a default.

    Coal and mining haul vehicles

    Kentucky's eastern coal counties see heavy commercial truck traffic, and vehicles hauling loads between mine sites and processing facilities on public roads must carry the full KRS 281.655 weight-based limits. Once that haul enters a federal highway or feeds into an interstate shipment, FMCSA minimums apply instead.

    Farm vehicles on public roads

    Kentucky's farm vehicle exemption disappears the moment a truck or trailer pulls onto a public highway, even for a half-mile stretch between fields. A farm vehicle hauling produce to a Lexington farmers market on a state road needs at least 25/50/25 commercial coverage, a gap that catches seasonal operations off guard during harvest.

    Vehicles crossing into bordering states

    Kentucky shares borders with seven states, and a work vehicle that routinely crosses into Ohio, Indiana, Tennessee, West Virginia, Virginia, Missouri or Illinois may trigger those states' requirements or federal interstate rules. Confirm your policy covers multi-state operations and that your insurer knows about the cross-border routes.

    Choice no-fault PIP on commercial policies

    Kentucky's PIP requirement carries into commercial auto policies by default, covering medical expenses and lost wages up to $10,000 regardless of fault. You can reject PIP in writing, but that rejection only strips first-party medical coverage from listed drivers and employees. A driver injured in a work vehicle crash with no PIP would need workers' compensation or personal health insurance to cover those costs.

Commercial Auto Insurance Enforcement and Penalties in Kentucky

Kentucky doesn't rely solely on traffic stops to catch uninsured vehicles. The state's Electronic Insurance Verification System pulls monthly reports from every insurer, and the AVIS database flags any vehicle missing coverage for two consecutive months, triggering an automatic uninsured notice from the Division of Motor Vehicle Licensing.

First offense
$500
Registration suspended up to 12 months
Proof of insurance + $40 reinstatement fee
Second offense (within 5 years)
$1,000–$2,500
Registration suspended; license may be revoked
Six-month premium payment + court fines
Third or subsequent (within 5 years)
$1,000–$2,500
Extended suspension; vehicle may be impounded
Retake driving exam if suspension exceeds one year
Any offense
Up to 90 days jail (first); up to 180 days (repeat)

Kentucky doesn't require SR-22 filing to reinstate a suspended registration. You provide proof of active coverage and pay the $40 fee under KRS 186.040 (amended in 2024). That doesn't mean enforcement is lenient: the Electronic Insurance Verification System catches lapses automatically, and under KRS 304.39-060 an uninsured vehicle owner who gets into an accident forfeits the first $10,000 in medical expenses and lost wages they'd otherwise recover from the at-fault driver.

How to Verify Your Kentucky Commercial Auto Insurance Requirements

Walk through these seven steps for every vehicle your business owns or operates in Kentucky.

  1. 1

    Identify how each vehicle is used

    Kentucky ties coverage requirements to vehicle use and weight, not business type. Pin down whether each vehicle moves passengers, hauls cargo, makes local runs or crosses state lines.

  2. 2

    Check each vehicle's weight rating

    Kentucky's intrastate carrier limits jump at 10,001 and 18,001 pounds under KRS 281.655, so pull the GVWR from the driver-side door jamb and classify each vehicle on the correct side of those thresholds.

  3. 3

    Determine whether state or federal rules apply

    A single interstate trip with cargo or passengers can shift a vehicle from Kentucky's intrastate tiers to federal FMCSA minimums, including moves that are part of a larger interstate shipment chain.

  4. 4

    Confirm your liability limits meet the correct tier

    Match each vehicle to 25/50/25 for local use, 100/300/50 or 100/600/50 for intrastate carriers by weight, or $750,000 to $5 million CSL for interstate and hazmat operations.

  5. 5

    Verify your policy classifies each vehicle correctly

    Every vehicle on your Kentucky commercial auto policy should be listed with the right use code and all authorized drivers named. A delivery van coded as a personal vehicle creates a gap your insurer will cite to deny a claim.

  6. 6

    Confirm registrations and filings are current

    Interstate carriers need a USDOT number and FMCSA filings (BMC-91 or BMC-91X plus MCS-90). Kentucky intrastate passenger carriers must file a Form E with the Division of Motor Carriers.

  7. 7

    Check for Kentucky-specific coverage gaps

    Confirm your PIP election status and what rejecting it removes. Verify multi-state coverage if vehicles cross into bordering states. Compare lease insurance clauses against your actual policy limits.

Kentucky Commercial Auto Insurance Requirements: Bottom Line

Your PIP election, vehicle weight classifications and whether any route touches interstate commerce are the three factors that shape what Kentucky requires from your commercial auto policy. Match each vehicle to the right tier, verify your policy's use classifications reflect reality and close any gaps between legal minimums and what your contracts demand.

Kentucky Commercial Auto Insurance Requirements: Next Steps

Legal minimums tell you what Kentucky and federal law require, but they don't tell you what your business can afford to leave uncovered. The gap between a 25/50/25 policy and a serious liability claim is where the real financial hit lands, so the next decision is how far above the floor your coverage should go.

If your goal is legal compliance

If your vehicles are valuable or highly visible

If you transport passengers

If you haul goods or equipment

If your business signs contracts

If your vehicles regularly cross into bordering states
