Hit-and-Run Fault Rules by State

Fault rules vary by state and directly control what happens to your hit-and-run uninsured motorist claim. In some states, any fault assigned to you wipes out the entire claim. In others, fault only reduces the payout. Knowing which rule applies where you were hit determines how to approach your own insurer and what evidence matters most.

Why Fault Rules Matter When the Other Driver Fled

After a hit-and-run, your claim typically runs through your own uninsured motorist coverage. That means your insurer -- the company you pay premiums to -- decides how much to pay. One of its primary tools for reducing or denying the claim is the fault rule in your state.

Fault rules determine whether shared blame reduces your payout or eliminates it. In states with harsh rules, even a small fault finding can cost you the entire claim. In states with more protective rules, fault only reduces the award proportionally. The difference between these frameworks can be the difference between full recovery and nothing.

Five Fault-Rule Categories Across the States

States fall into five fault-rule categories, each with a different effect on hit-and-run UM claims:

  • Contributory negligence -- any fault on your part bars the entire claim. Five jurisdictions use this rule.
  • Pure comparative fault -- fault reduces the payout by your percentage but never eliminates it. Eleven states follow this standard.
  • Modified comparative fault (50% bar) -- fault at or above 50 percent bars the claim entirely. Eleven states use this threshold.
  • Modified comparative fault (51% bar) -- fault must exceed 50 percent to bar the claim. Twenty-three states apply this rule.
  • Slight/gross negligence -- recovery requires your fault to be slight compared to the other party's gross negligence. Only South Dakota uses this standard.

Contributory negligence — any fault can bar the claim

Slight/gross negligence

Modified comparative — barred at 50%

Modified comparative — barred at 51%

Pure comparative — reduced, never barred

Hit and run state pages by region

Each state page applies one state's fault rule to a hit-and-run claim paid through your own uninsured motorist (UM) coverage. Your insurer can use any fault it assigns to you to cut or deny the payout, so the rule in your state shapes the whole claim. Every page explains that rule, the evidence that keeps your share of fault low and a worked example with illustrative numbers, then covers filing the UM claim and answers three common questions. The estimator on each page opens with that state already selected. Below, the 50 states and DC are grouped into the four U.S. Census Bureau regions: Northeast, Midwest, South and West. The line after each state is taken from that state's own page. Fault rules change, so check the current rule in your state's statutes or with a licensed attorney before you rely on it.

Northeast

  • Connecticut: In Connecticut, your hit-and-run UM claim survives unless the insurer proves your fault exceeded 50 percent.
  • Maine: Maine's comparative fault rule blocks recovery when your fault reaches 50 percent or higher.
  • Massachusetts: Massachusetts requires your fault to exceed 50 percent before barring a UM claim.
  • New Hampshire: New Hampshire sets the UM recovery bar at 51 percent fault. After a hit-and-run, your claim remains valid so long as the insurer cannot assign you a majority share of blame.
  • New Jersey: New Jersey's comparative fault rule shields hit-and-run UM claimants whose fault stays at or below 50 percent.
  • New York: Under New York's pure comparative fault rule, a hit-and-run UM claim pays at every fault level.
  • Pennsylvania: Reaching 51 percent fault in Pennsylvania bars your hit-and-run UM claim entirely.
  • Rhode Island: Rhode Island's pure comparative fault framework prevents any fault assignment from ending a hit-and-run UM claim.
  • Vermont: Vermont bars UM hit-and-run recovery only when your fault exceeds 50 percent.

Midwest

  • Illinois: Illinois bars hit-and-run UM recovery only when the claimant's fault exceeds 50 percent.
  • Indiana: Equal fault still allows recovery in Indiana, where the comparative fault bar sits at 51 percent.
  • Iowa: For a hit-and-run UM claim in Iowa, the comparative fault bar sits at 51 percent.
  • Kansas: Fault assignments in Kansas hit-and-run UM claims face a 50-percent comparative threshold. Once the insurer argues your share reached that line or above, the entire claim fails.
  • Michigan: You can be assigned exactly half the fault and still recover.
  • Minnesota: Minnesota applies a 51-percent comparative fault bar, so your insurer must attribute more than half the fault to you before it can refuse payment on a hit-and-run UM claim.
  • Missouri: Missouri treats hit-and-run UM disputes under pure comparative fault.
  • Nebraska: Reaching an even fault split in Nebraska eliminates your hit-and-run UM claim under the state's 50-percent bar.
  • North Dakota: North Dakota applies a 50-percent comparative fault bar to UM claims. A hit-and-run claimant who reaches an equal fault share with the phantom driver recovers nothing under this rule.
  • Ohio: Ohio's comparative fault bar blocks UM recovery only past the 50-percent mark.
  • South Dakota: South Dakota's slight/gross rule is the outlier: this claim survives only if your negligence was 'slight' compared with the other side's.
  • Wisconsin: As long as your fault does not exceed 50 percent, Wisconsin preserves your hit-and-run UM recovery.

South

  • Alabama: After a hit-and-run in Alabama, your UM insurer has a powerful defense: the state's pure contributory negligence rule lets it deny the entire claim if it can assign you any fault at all.
  • Arkansas: Because Arkansas uses a 50-percent comparative fault bar, a hit-and-run UM claimant found equally at fault recovers nothing.
  • Delaware: Delaware's modified comparative fault system blocks UM recovery only at 51 percent fault or higher.
  • District of Columbia: Pure contributory negligence still governs the District of Columbia.
  • Florida: Filing a hit-and-run UM claim in Florida means your fault must stay at or below 50 percent.
  • Georgia: Georgia's comparative fault rule blocks recovery when your fault reaches 50 percent or higher.
  • Kentucky: Pure comparative fault in Kentucky preserves hit-and-run UM claims at any level of assigned blame.
  • Louisiana: Louisiana follows pure comparative fault, which means your hit-and-run UM claim pays the remaining share no matter how much fault the insurer attributes to your driving.
  • Maryland: Maryland is among the strictest jurisdictions for hit-and-run UM claims. Its pure contributory negligence rule lets the insurer deny your entire recovery if it can assign you even a fraction of fault.
  • Mississippi: Mississippi's pure comparative fault rule makes it impossible for a fault assignment to destroy your hit-and-run UM claim.
  • North Carolina: North Carolina's pure contributory negligence rule places hit-and-run UM claimants at severe risk. If the insurer attributes any fraction of fault to you, it can deny the full claim.
  • Oklahoma: Oklahoma uses a 51-percent fault bar for UM disputes. After a hit-and-run, your claim remains payable as long as the insurer cannot attribute more than half the fault to your actions.
  • South Carolina: South Carolina blocks UM recovery only when fault exceeds 50 percent.
  • Tennessee: Tennessee's 50-percent fault bar makes every percentage point critical in a hit-and-run UM claim. An equal fault assignment wipes out the claim; anything below it keeps recovery alive.
  • Texas: Texas follows modified comparative fault with a 51-percent bar. Your hit-and-run UM claim remains viable provided the insurer cannot show you were more responsible than the fleeing driver.
  • Virginia: Under Virginia's contributory negligence rule, any amount of fault attributed to you is enough to bar the claim.
  • West Virginia

West

  • Alaska: Alaska applies pure comparative fault, so no percentage of assigned blame can eliminate your hit-and-run UM claim.
  • Arizona: Your hit-and-run UM claim in Arizona survives any fault assignment because the state follows pure comparative fault.
  • California: California's pure comparative fault rule keeps every hit-and-run UM claim alive regardless of the fault split.
  • Colorado: Colorado sets a hard 50-percent fault bar for injury claims, including UM disputes. If your insurer assigns you half the blame for a hit-and-run, the claim is gone.
  • Hawaii: Hawaii protects hit-and-run UM claimants whose assigned fault stays at or below 50 percent.
  • Idaho: A 50-percent comparative fault bar controls UM disputes in Idaho. If the insurer assigns you an equal share of fault after a hit-and-run, you lose the entire claim.
  • Montana: Only when your assigned fault exceeds 50 percent does Montana bar UM hit-and-run recovery.
  • Nevada: The fault bar in Nevada sits at 51 percent for UM claims. Your hit-and-run case holds unless the insurer can prove you carried more than half the responsibility for the crash.
  • New Mexico: New Mexico uses pure comparative fault, keeping hit-and-run UM claims alive regardless of the fault distribution.
  • Oregon: Exceeding 50 percent fault is the only way an insurer can block your hit-and-run UM claim in Oregon.
  • Utah: An even split of fault between you and the phantom driver eliminates your hit-and-run UM claim in Utah, where the comparative fault bar sits at 50 percent.
  • Washington: Washington's pure comparative fault rule means your hit-and-run UM claim cannot be defeated by any level of assigned fault.
  • Wyoming: Wyoming applies a 51-percent fault bar to UM disputes.

Questions

Fault-rule questions

Does equal fault bar my hit-and-run UM claim in your state?

No. your state uses a 51-percent comparative fault bar, so equal fault -- 50 percent -- does not block your claim. You lose recovery only when your assigned fault exceeds 50 percent. At the even split, you still receive a proportionally reduced payout from your carrier.

Can my UM insurer deny my hit-and-run claim entirely under your state's fault rule?

No. your state follows pure comparative fault, which means no fault percentage can eliminate your UM claim. The insurer reduces your payout by the percentage of fault it attributes to you, but the claim itself survives at every level. Your focus should be on minimizing the assigned percentage.

Does contributory negligence apply to UM hit-and-run claims in your state?

Yes. your state applies the contributory negligence rule to UM claims just as it does to standard injury disputes. If your insurer determines that you bore any fault in the hit-and-run -- even a small percentage -- it can deny the entire UM claim. No partial recovery exists under this standard.
