Fault system in Kentucky: no-fault vs at-fault

Kentucky doesn't sit cleanly in either camp. Most states are strictly one thing: you either sue the at-fault driver for everything, or you turn to your own no-fault coverage first and mostly stay out of court. Kentucky is one of a small group of "choice" no-fault states, so you start inside the no-fault system but keep the right to opt out, and you keep the right to sue the driver who hit you once your injuries pass a set threshold.¹ If you were just in a crash here, that design changes who pays your first medical bills and how long you have to sue.

You're in the no-fault system by default

The rule lives in Kentucky's Motor Vehicle Reparations Act. Under KRS 304.39-060, anyone who registers, operates, maintains, or uses a vehicle on Kentucky's public roads is "deemed to have accepted" the no-fault limits as a condition of driving here.¹ You never sign anything. Buying gas and pulling onto the interstate is enough.

Accepting no-fault does two things after a crash. Your own insurer pays certain economic losses no matter who caused the wreck. In exchange, your right to sue the at-fault driver for pain and suffering is limited unless your injuries are serious enough to clear the statutory threshold.¹

You can refuse that trade. KRS 304.39-060 lets any driver reject the tort limitations in writing, on a form the Department of Insurance prescribes, filed before any accident it is meant to cover.¹ A rejection preserves your full right to sue in every crash, but almost no one files one, so the default controls nearly every Kentucky case. Motorcyclists have a separate option: an owner or operator can reject the limits for motorcycle use alone, which is part of why motorcycle claims often follow different rules than car claims.¹

What no-fault actually pays

Kentucky's no-fault benefit is called Basic Reparation Benefits, or BRB. Other states call the same thing PIP. Every standard auto policy has to carry it, and it pays up to $10,000 per person, per accident, for economic loss.² That $10,000 is a hard ceiling on all covered losses combined, regardless of how many insurers are involved.²

BRB covers three kinds of loss: medical expense, work loss (the income you lose while you are hurt), and replacement services (paying someone to do the household tasks you cannot).² Funeral and burial costs are included, capped at $5,000.² It does not pay for pain and suffering. That is noneconomic loss, and it lives on the tort side of the system.

Prompt payment is a legal duty here, not a favor. Under KRS 304.39-210, a BRB payment is overdue if your insurer does not pay within 30 days of receiving reasonable proof of the loss.³ Overdue benefits carry 12% annual interest, and if the insurer delayed without reasonable foundation the rate rises to 18% and you can recover attorney's fees for collecting.³⁴

One recent change matters if your crash is fresh. A 2026 amendment, effective July 15, 2026, ties the medical charges BRB will pay to Kentucky's workers' compensation fee schedule and requires providers to bill within 180 days.²³ It applies to policies issued or renewed on or after that date.

When you can step outside no-fault and sue

This is where Kentucky behaves like an at-fault state. You can shed the no-fault limits and bring a full injury claim against the driver who hit you, pain and suffering included, once you meet the threshold in KRS 304.39-060.¹ You qualify if either:

• your medical expenses exceed $1,000, or
• your injury involves a bone fracture, permanent disfigurement, permanent injury, permanent loss of a bodily function, loss of a body member, or death.¹

A thousand dollars is a low bar. One ER visit with imaging often clears it, which is why so many Kentucky crashes turn into ordinary at-fault claims. The fracture and permanent-injury categories exist so a serious injury qualifies even when the bills somehow stay low.¹

Some people are never confined to no-fault at all. KRS 304.39-060 says the tort limits do not apply to a person who is not an owner, operator, or user of a motor vehicle, or to a motorcycle passenger.¹ So a pedestrian or bicyclist struck by a car, and a passenger on a motorcycle, can sue the at-fault driver without clearing the threshold.

How fault gets divided

Once you are in a liability claim, Kentucky uses pure comparative negligence. The Kentucky Supreme Court adopted it in Hilen v. Hays in 1984 and scrapped the old rule that any fault by the injured person destroyed the claim.⁵ The legislature later set out how fault is apportioned in KRS 411.182.⁶

"Pure" is the operative word. Your recovery shrinks by your share of fault, but it never vanishes, even if you were more to blame than the other driver. A jury that finds you 30% at fault on $100,000 in damages awards you $70,000. Someone found 80% at fault still collects 20%. Kentucky sets no cutoff percentage that bars recovery, which sets it apart from the "modified" comparative states nearby.⁵⁶

The insurance behind the claim

A tort claim usually reaches the at-fault driver's liability coverage first. Kentucky's minimum is 25/50/25: $25,000 for bodily injury to one person, $50,000 per accident, and $25,000 for property damage, or a single-limit policy of at least $60,000.⁷ The property-damage figure rose to $25,000 for policies issued or renewed on or after January 1, 2018, so it is not the frozen 1970s number some guides still quote.⁷

Those limits are thin, and many drivers carry only the minimum or nothing. Two coverages on your own policy fill the gap. Uninsured motorist (UM) coverage is built into every Kentucky auto policy at your liability limits unless you reject it in writing, and a rejection is valid only when the named insured signs it.⁸ Underinsured motorist (UIM) coverage, which covers the shortfall when the at-fault driver's limits run out, works differently: your insurer only has to offer it, and you have to request it to have it.⁹ Check your declarations page, because these are often the line between a real recovery and a paper judgment.

Deadlines that end your claim

Kentucky's injury deadline for a car crash is not the state's general one-year personal-injury limit. Under the Reparations Act, you have two years to sue for a motor-vehicle injury, measured from the accident or from the last BRB payment made on your claim, whichever is later.¹⁰ Because BRB payments can push that start date forward, the clock often runs longer than people expect, but never assume it without confirming your payment dates.

Vehicle damage runs on a separate two-year clock. A claim for damage to your car falls under KRS 413.125, measured from the date of loss, and unlike the injury deadline it is not extended by insurance payments.¹¹ If your car lost market value even after a clean repair, that is a separate diminished value claim. And if you still need the official record of the wreck, start with your Kentucky crash report.

Kentucky's choice design hands you more control than drivers in most states get, but only if you use it before these deadlines close. If your injuries clear the threshold, or your losses run past your BRB, talking with a Kentucky attorney early is how you keep the at-fault option open.
