When the driver who hits you has no insurance, the situation flips in a way most people don’t expect: you file a claim with your own insurance company. Uninsured motorist coverage — UM coverage — exists specifically for this scenario. Understanding how it works before you need it, and what to do if you’re already in the middle of a claim, can make a significant difference in what you recover.
What Is Uninsured Motorist Coverage?
Uninsured motorist coverage is a component of your own auto insurance policy that pays for your injuries and losses when the at-fault driver carries no liability insurance. Most states require insurers to offer it; several states require drivers to carry it.
A related but distinct coverage is underinsured motorist coverage (UIM). UIM applies when the at-fault driver has some insurance, but their policy limits aren’t enough to cover your damages. If someone with a $25,000 bodily injury policy causes $150,000 in medical bills, your UIM coverage can make up the gap — up to your own policy limits.
Both coverages work through your own insurer, which creates a dynamic worth understanding before you file: the company you pay premiums to becomes the entity you’re negotiating against.
When You Can File a Uninsured Motorist Claim
UM coverage applies in three main situations:
- The at-fault driver has no auto insurance. This is the classic UM scenario — another driver causes the crash and carries no liability coverage at all.
- Hit-and-run accidents. When a driver flees the scene and can’t be identified, most UM policies treat the unknown driver as uninsured. You typically need to report the accident to police promptly and provide documentation of your injuries and damages.
- The at-fault driver’s coverage is inadequate (UIM). If their liability limits are too low to cover your actual damages, your underinsured motorist coverage fills the gap between what their policy pays and your full losses — up to your own UIM limits.
How to File an Uninsured Motorist Claim
- Report the accident to your insurer promptly. Most policies require notification within a set window — sometimes as short as 30 days. Don’t wait. Provide the basic facts: date, location, what happened, and that the other driver was uninsured or fled the scene.
- Get a police report. For UM claims — and especially hit-and-run claims — a police report filed the same day is critical. Without one, your insurer may dispute whether the accident occurred as you described.
- Seek medical treatment immediately. Get evaluated that day or the next. Delayed treatment creates a documentation gap that adjusters use to question the severity or cause of your injuries.
- Document everything. Photographs of the accident scene, vehicle damage, and your injuries. Witness contact information. Any communications from the police or other parties. Medical bills and records from every provider involved in your treatment.
- File a formal UM claim with your insurance company. Your insurer will assign an adjuster and request documentation. Provide what’s asked for, but do not give a recorded statement before speaking with an attorney — UM adjusters work for the same company whose profits depend on minimizing payouts.
- Know your policy limits. Your recovery is capped at whatever UM/UIM limits you chose when you bought your policy. If you have $100,000 in UM coverage and $200,000 in medical bills, you will not recover more than $100,000 from this claim. This is why adequate UM coverage is worth the premium.
What Uninsured Motorist Claims Are Worth
UM claims can cover the same categories of damages as any personal injury claim:
- Medical expenses — past and future treatment, surgery, physical therapy, prescription costs
- Lost wages — time missed from work during treatment and recovery
- Diminished earning capacity — if your injury limits your ability to work the same job long-term
- Pain and suffering — the non-economic impact of the injury on your daily life
- Property damage — repair or replacement of your vehicle, if your policy includes it
The ceiling on all of this is your policy’s UM limit. This is one of the clearest reasons why carrying meaningful UM coverage — $100,000 or more in bodily injury UM, not the state minimum — matters. Checking your own policy limits is worth doing before you’re in an accident.
How Insurers Handle UM Claims — and Why They Dispute Them
Filing a UM claim feels like it should be straightforward — you pay premiums, you’re hurt, your insurer pays. The reality is often more adversarial than that.
Your own insurance company has a financial interest in minimizing what it pays you. Adjusters are trained to find reasons to reduce your claim: questioning whether the accident caused your specific injuries, requesting independent medical examinations from doctors the company selects, arguing that your treatment was excessive, or offering a fast lowball settlement before you understand your full damages.
This doesn’t mean every insurer behaves this way in every case. But when the stakes are high — serious injuries, significant medical bills, lost wages — disputes are common. The insurer’s tactics in a UM claim often mirror what you’d expect from an opposing party’s lawyer, not from your own coverage provider.
In some states, there are arbitration requirements for UM disputes. Others allow you to file a bad faith insurance claim if your insurer unreasonably delays or denies a valid UM claim. An uninsured motorist lawyer can tell you which rules apply in your state and whether your insurer’s conduct crosses the line.
When to Hire a Lawyer for Your UM Claim
You should talk to a car accident attorney before giving your insurer a recorded statement in any of these situations:
- Your injuries required medical treatment beyond a routine ER visit
- You’ve missed work or your injury affects your ability to do your job
- Your insurer is disputing the cause or severity of your injuries
- You received a settlement offer that doesn’t cover your actual medical bills
- Your damages are close to or exceed your UM policy limits
- The accident involved a hit-and-run and your insurer is pushing back on the claim
Personal injury attorneys handle UM claims on contingency — no fee unless there’s a recovery. The same structure that applies to any personal injury claim applies here. Consulting one costs nothing and gives you a clearer picture of what your claim is actually worth versus what your insurer is offering.
One note on UM claims and average car accident settlements: settlement amounts in UM cases are shaped by your policy limits in a way that third-party claims are not. An attorney familiar with UM litigation in your state knows what those limits realistically mean for your specific situation and can negotiate accordingly.
Frequently Asked Questions
Does filing a UM claim affect my insurance rates?
In most states, insurers cannot raise your rates for filing a UM claim caused by an uninsured driver — you were the victim, not the at-fault party. However, the rules vary by state and by insurer. Your agent can confirm your specific policy language. If your insurer threatens to raise rates for filing a legitimate UM claim, that may constitute bad faith conduct worth discussing with an attorney.
What if the uninsured driver later gets insurance or assets?
You may still be able to pursue a separate civil claim against the at-fault driver directly, independent of your UM coverage. Winning a judgment doesn’t guarantee payment — most uninsured drivers are uninsured because they can’t afford it — but depending on the facts, a personal injury lawsuit against the driver may be worth evaluating alongside your UM claim.
How long does a UM claim take?
Straightforward claims where liability is clear and injuries are well-documented can resolve in a few months. Disputed claims — especially those involving significant injuries or gaps in coverage — can take a year or longer, particularly if arbitration or litigation is required. The timeline is influenced heavily by how aggressively your insurer contests the claim and how quickly you reach maximum medical improvement.
