How Uninsured Motorist Coverage Works in Indiana

Uninsured motorist coverage in Indiana is built into every auto insurance policy sold in the state, and it stays on your policy unless you sign a written rejection. It pays for your injuries, and in some cases your vehicle damage, when the driver who hit you carries no liability insurance or when their insurer has gone insolvent. The default minimum is $25,000 per person and $50,000 per accident for bodily injury, matching Indiana’s minimum liability requirements, though most drivers benefit from carrying more.

How the Automatic-Coverage Rule Works

Indiana law doesn’t force you to carry uninsured motorist (UM) coverage, but it makes going without it a deliberate act. Every insurer writing auto policies in the state must include UM coverage automatically. It only comes off if you sign a written rejection that names the coverage you’re dropping and the effective date.¹ Your insurer keeps that signed rejection on file. If you never signed one, you have UM coverage, even if you never thought about it.

UM and underinsured motorist (UIM) coverage are separate. UM applies when the at-fault driver has no insurance. UIM applies when they have insurance but not enough to cover your losses. Indiana lets you reject them together or separately, so it’s possible to carry one without the other. Keeping both is the broader protection.

What “Uninsured” Actually Means

An uninsured motor vehicle under Indiana law includes any vehicle without liability insurance or one that otherwise fails to meet the state’s financial responsibility requirements. It also includes a vehicle whose insurer has become insolvent.² That second category catches people off guard. If the other driver technically had a policy but the insurance company collapsed before paying, your UM coverage treats it the same as if they’d had nothing.

Coverage Limits and What They Cost You in a Real Claim

The minimum UM bodily injury limits are $25,000 per person and $50,000 per accident, tracking the state’s minimum liability numbers.³ Your insurer must offer UM at limits at least equal to your policy’s bodily injury liability limits, and you’re allowed to buy more.¹

One ER visit and a surgery can burn through $25,000. Add lost wages and physical therapy, and the minimum leaves a real gap. The people who trigger UM claims are, almost by definition, people you can’t collect from personally, so the coverage you buy is usually the coverage you get. Limits of $100,000/$300,000 or higher are worth the modest bump in premium for most drivers.

Uninsured Motorist Property Damage

Bodily injury UM is one thing; damage to your car is another. Indiana insurers must offer uninsured motorist property damage (UMPD) coverage, which pays for damage to your vehicle and personal belongings inside it when an uninsured driver is at fault. Insurers must offer a no-deductible option and may also offer versions with a deductible of up to $300. If your car was legally parked and unoccupied at the time of the collision, the deductible is waived entirely.⁴

There’s a catch. To file a UMPD claim, you have to identify the at-fault driver by name and address and show they lacked insurance. If the driver fled and can’t be identified, UMPD won’t respond. Collision coverage is what covers vehicle damage in an unidentified hit-and-run.

Who Your UM Policy Protects

UM coverage isn’t limited to you sitting behind the wheel of the insured car. Family members living in your household who don’t have their own auto policy are generally covered under yours, which matters for teenagers, elderly parents, and other relatives without their own vehicles.

The coverage also follows you when you’re not driving. Struck by an uninsured driver while walking through a parking lot or riding a bicycle? Your own auto policy’s UM coverage can pay for those injuries. It’s one of the least-known features of UM insurance and one of the strongest arguments against rejecting it.

Filing a UM Claim in Indiana

After a crash with an uninsured driver, your first call is to your own insurance company, not the other driver’s nonexistent carrier. Most policies require prompt notification. Many use a 30-day window, but sooner is better. Delay gives an adjuster a procedural reason to push back before they even look at the facts.

Call the Police to the Scene

Indiana law requires drivers involved in an accident causing injury or death to notify law enforcement immediately, and significant property damage triggers a written crash report requirement. Call police even when injuries look minor. The report creates the official record of what happened and often documents the other driver’s insurance status. It becomes the spine of your UM claim.

Confirm the Other Driver Was Uninsured

Your insurer will investigate, but you can help. At the scene, ask for the other driver’s insurance card, license, and registration, and check that names and policy numbers line up. If they can’t or won’t produce coverage information, get a copy of the police report, ask your insurer to verify through industry databases, and consider contacting Indiana’s Bureau of Motor Vehicles with the driver’s information to check whether coverage was active.

Document What You Can, When You Can

Photos of vehicle damage, road conditions, skid marks, and injuries are easy to take at the scene and hard to recreate. Save medical records and bills from day one. Track missed work and lost income. Keep repair estimates. Get contact information from any witnesses, because they can back up your version if the insurer starts questioning liability later.

Comparative Fault and the 51% Cliff

Indiana uses a modified comparative fault system. If you share some blame for the accident, your UM payout drops by your share of fault. If an insurer or arbitrator assigns you 20% of the fault, a $50,000 award becomes $40,000.⁵

The trap is the 51% threshold. Once your share of fault crosses 50%, you recover nothing. It isn’t a sliding scale at that point; it’s a cliff. An insurer evaluating a UM claim has every incentive to push your fault percentage over that line, because doing so eliminates the payout entirely. That’s why the police report and witness statements carry so much weight. They fix the facts at the scene, before memories drift and the insurer builds its own narrative.

Hit-and-Run Accidents

Hit-and-run crashes create particular problems. For bodily injury UM claims, coverage can apply when the other driver flees, but many policies include a physical contact requirement. If the other vehicle never touched yours, such as when a driver forces you off the road and keeps going, the claim gets harder. You’ll usually need independent evidence beyond your own testimony to prove the phantom vehicle existed.

Property damage after a hit-and-run is even harder. Indiana’s UMPD statute requires you to identify the at-fault driver by name and address, so an unidentified hit-and-run driver puts UMPD out of reach.⁴ Collision coverage is the fallback. Note any detail you can about the other vehicle: make, model, color, plate, direction of travel. Dashcam footage helps. Even a partial plate can let police identify the driver, which reopens both UM and UMPD.

Common Reasons UM Claims Get Denied

UM claims get denied more often than people expect. The usual reasons repeat:

Late reporting. Missing your policy’s notification deadline is the fastest way to lose an otherwise valid claim. Insurers argue late notice prevented them from investigating while evidence was fresh, and Indiana courts tend to be receptive to that argument.
Failure to identify the other driver. UMPD claims require the at-fault driver’s identity. Some policies also require physical contact or independent corroboration for hit-and-run bodily injury claims.
Disputed liability. If the insurer determines you were more than 50% at fault, comparative fault bars recovery entirely.⁵
Policy exclusions. Coverage may not extend to certain vehicles, drivers not listed on the policy, or specific situations spelled out in the endorsement. The UM endorsement itself is where those limits live.

One practical warning: your insurer will probably ask for a recorded statement during the investigation. You’re generally obligated to cooperate, but the statement can be mined later for inconsistencies. Stick to what you actually know, say “I don’t know” when that’s the truth, and consider having an attorney present.

Stacking Coverage Across Multiple Vehicles

If you insure more than one vehicle on the same policy, you may be able to “stack” the UM limits from each vehicle into a single larger pool. Two vehicles each carrying $50,000 per person could, in theory, yield $100,000 in available benefits for one claim.

Many Indiana insurers write anti-stacking language into their policies, and Indiana courts have generally enforced clear anti-stacking provisions when the wording unambiguously limits recovery to a single vehicle’s coverage. Before assuming you can stack, check your declarations page and UM endorsement. Ambiguous language is worth raising with your insurer or an attorney, because ambiguity in insurance contracts is typically read in the policyholder’s favor.

If the Insurer Won’t Pay Fairly

Many Indiana UM policies push disputes into arbitration rather than court. A neutral third party reviews the evidence and issues a binding decision on liability, damages, or both. Arbitration is faster than litigation, but you usually give up the right to appeal an unfavorable result. Check for a mandatory arbitration clause in the UM endorsement before you sign, because once you’ve agreed, you’re bound.

If your insurer ignores evidence, delays payment without justification, misrepresents your policy terms, or lowballs after a sloppy investigation, Indiana law defines those behaviors as unfair claim settlement practices.⁶ Individual policyholders can’t sue directly under that statute; enforcement actions belong to the Indiana Department of Insurance. Your personal remedy is a common-law bad faith lawsuit, where you’d have to show the insurer had no reasonable basis for denying or undervaluing your claim. A successful bad faith case can produce damages beyond the original policy limits.

When UM Coverage Isn’t Enough

Even a successful UM claim may not cover everything. Medical bills, lost income, and long-term rehabilitation can outrun policy limits fast. A few options can help close the gap.

Underinsured motorist (UIM) coverage. If the at-fault driver had some insurance but not enough, UIM picks up where their liability policy left off. UIM is separate from UM in Indiana and can’t be sold in amounts less than $50,000.¹
Medical payments (MedPay) coverage. If your policy includes it, MedPay reimburses medical expenses regardless of fault and pays on top of UM benefits.
A lawsuit against the at-fault driver. Suing someone with no insurance is often pointless, but if they own property, earn a steady income, or have other assets, a judgment lets you pursue wage garnishment or property liens. The math depends on what’s actually collectible.
Indiana Victim Compensation Program. When a crash involves criminal conduct such as drunk driving, injured victims may be eligible for compensation through Indiana’s Violent Crime Victim Compensation fund. It’s a fund of last resort covering medical expenses and other losses when no other source will pay.⁷

The Two-Year Deadline

Indiana’s statute of limitations for personal injury claims is two years from the date of the accident.⁸ That deadline applies to UM claims, and Indiana courts have confirmed that insurers can enforce a two-year contractual limitation on UM claims that mirrors the tort statute. Miss it and you lose the right to sue or compel arbitration, no matter how strong the underlying facts are. Two years feels like plenty until treatment drags on and negotiations stall. Treat the date as a hard wall.
