Kentucky Does Not Require Underinsured Motorist Coverage
You are confirming whether Kentucky requires underinsured motorist coverage because you are structuring coverage across two or more vehicles and need to know what is mandatory versus optional. Kentucky law requires uninsured motorist coverage but does not require underinsured motorist coverage. The distinction matters: uninsured motorist (UM) covers you when the at-fault driver has no insurance at all, while underinsured motorist (UIM) covers you when the at-fault driver carries insurance but their limits are too low to pay your full damages.
Most carriers bundle UM and UIM together as a single coverage line, so when you add uninsured motorist coverage to meet Kentucky's mandate, you typically have the option to add underinsured protection at the same time. The decision is whether to accept that bundled coverage or decline the underinsured portion. With 14.1% of Kentucky drivers uninsured and many others carrying only the state minimum $25,000 bodily injury per person limit, the gap between what an at-fault driver's policy pays and what your household's damages actually cost can be substantial when multiple vehicles are involved in a crash.

One in seven Kentucky drivers operates without insurance. When combined with drivers carrying only minimum $25,000 limits, the probability that an at-fault driver's policy will not fully cover your household's damages rises significantly.

What Kentucky Requires and What It Does Not
Kentucky requires every driver to carry uninsured motorist coverage with limits at least equal to the bodily injury liability limits on the policy. If you carry the state minimum $25,000 per person and $50,000 per accident in liability, you must carry at least $25,000/$50,000 in uninsured motorist coverage. You cannot decline UM coverage in Kentucky.
Kentucky does not require underinsured motorist coverage. You may decline it entirely, or you may add it with limits up to the liability limits on your policy. Most carriers offer UM/UIM as a combined coverage, meaning you select one set of limits that applies to both uninsured and underinsured claims. A household insuring multiple vehicles on one policy selects UM/UIM limits once, and those limits apply per person and per accident regardless of which vehicle is involved in the crash.
The structural reality: Kentucky's mandatory UM coverage protects you when the at-fault driver has zero insurance. It does not protect you when the at-fault driver carries insurance but their $25,000 limit does not cover your medical bills, lost wages, and vehicle damage across two or more cars. That gap is what underinsured motorist coverage fills, and it is optional.
Kentucky mandates uninsured motorist coverage but not underinsured. The gap: an at-fault driver with minimum $25,000 limits cannot cover multi-vehicle household damages that exceed that amount.
How Underinsured Motorist Coverage Works in Kentucky
When an at-fault driver's bodily injury liability limit is lower than your damages, their insurer pays their policy limit first. Your underinsured motorist coverage then pays the remaining amount, up to your UM/UIM limit minus what the at-fault driver's policy already paid.
Kentucky law treats UM and UIM as separate triggers but most carriers bundle them under one combined limit. The limit is per person and per accident, not per vehicle.

Why Multi-Vehicle Households Face Higher Underinsured Risk
A household insuring two or more vehicles on one policy faces higher exposure to underinsured claims because a single crash can damage multiple vehicles and injure multiple household members. When an at-fault driver with minimum $25,000 per person and $50,000 per accident limits hits two of your household's cars, their $50,000 per-accident limit must cover property damage to both vehicles plus bodily injury to every injured person. That limit is exhausted quickly.
Kentucky's minimum property damage liability limit is $25,000 per accident. Your collision coverage on each vehicle pays the remainder minus your deductible, or you pay out of pocket if you do not carry collision. Underinsured motorist property damage coverage is available from some carriers as an optional add-on to UM/UIM, but it is not standard in Kentucky and many households rely on collision coverage instead.
The failure mode most households miss: adding a third or fourth vehicle to the policy increases the household's total asset value and the potential damage amount in a multi-vehicle crash, but it does not automatically increase UM/UIM limits. If you added vehicles to your policy within the past year and did not review your UM/UIM limits at the same time, your coverage may no longer match your exposure.
Kentucky Minimum Liability Limits
$25,000 / $50,000 / $25,000
Kentucky requires $25,000 bodily injury per person, $50,000 per accident, and $25,000 property damage. Many drivers carry exactly these minimums, leaving no margin when damages exceed those thresholds in multi-vehicle crashes.

Selecting UM/UIM Limits for Multiple Vehicles
Your UM/UIM limits should match or exceed your liability limits, and both should reflect the total value of assets your household would need to replace after a serious crash.
Compare Carriers Writing Multi-Vehicle Policies in Kentucky
Nineteen carriers write auto insurance in Kentucky and offer UM/UIM coverage as part of their multi-vehicle policies. Allstate, Geico, Progressive, State Farm, and Farmers all write households with two or more vehicles and bundle UM/UIM with the mandatory uninsured motorist coverage. Bristol West, Dairyland, and National General write non-standard and high-risk households and offer the same UM/UIM options. The UM/UIM premium varies by carrier even when the limits are identical, because each carrier prices the coverage based on its own claims experience and underwriting model.
When you compare quotes, confirm that each quote includes UM/UIM limits at least equal to your liability limits and that those limits apply per person and per accident, not per vehicle. Some carriers require you to actively select UM/UIM limits during the quote process; others default to minimum limits unless you request higher coverage. Use the site's comparison tool to request quotes from multiple carriers with identical UM/UIM limits so you can compare the total premium for your household's vehicles on an apples-to-apples basis.
