What to do when the other driver has no insurance. Complete guide to filing a UM/UIM claim.
When the Other Driver Has No Insurance
Getting hit by an uninsured or underinsured driver is a nightmare scenario. You did everything right — paid your premiums, drove safely — and the person who caused the accident has no way to pay for your damages. But if you have uninsured/underinsured motorist (UM/UIM) coverage on your own policy, you have a path to recovery.
Understanding UM/UIM Coverage
Uninsured Motorist (UM) Coverage
Covers you when the at-fault driver has no insurance at all, or when you are the victim of a hit-and-run.
Underinsured Motorist (UIM) Coverage
Covers you when the at-fault driver's insurance limits are not enough to cover your damages. If your damages are $100,000 and the other driver only has $25,000 in coverage, your UIM policy covers the gap.
Is It Required?
Many states require UM/UIM coverage. In states where it is optional, you may have signed a waiver declining it — check your policy declarations page.
Step-by-Step: Filing a UM/UIM Claim
Step 1: Confirm the Other Driver Is Uninsured/Underinsured
- Get the other driver's insurance information at the scene
- Your insurer will verify their coverage status
- For hit-and-runs, file a police report immediately (most policies require it within 24 hours)
Step 2: Report to Your Own Insurance Company
File a UM/UIM claim with your own insurer as soon as you confirm the other driver is uninsured or underinsured. Provide:
- Police report
- Accident documentation and photos
- The other driver's information
- Your medical records
Step 3: Understand the Tricky Dynamic
Here is the uncomfortable truth: you are now making a claim against your own insurance company. The same company you pay premiums to is now the company trying to minimize your payout. They have the same financial incentive to lowball you as any other insurer.
Do not let your relationship with your insurer make you less aggressive in pursuing fair compensation. Treat this like any other claim negotiation.
Step 4: Document Everything
Follow the same documentation protocol as any injury claim:
- Detailed medical records
- Lost wage documentation
- Pain journal
- All receipts and out-of-pocket costs
- Photos of injuries and vehicle damage
Step 5: Wait for MMI
Do not settle your UM/UIM claim until you have reached maximum medical improvement. Your future medical costs must be included in the settlement.
Step 6: Send a Demand Letter
Write a formal demand letter to your own insurer's claims department. Include all documentation, your damage calculation, and a specific demand amount.
Step 7: Negotiate
Your insurer will make an initial offer that is likely too low. Counter with evidence, just as you would with any other insurance negotiation.
Step 8: Arbitration (If Needed)
Most UM/UIM policies include an arbitration clause. If you cannot reach a settlement, the dispute goes to binding arbitration — a neutral third party decides the amount. This is faster and cheaper than a lawsuit.
Special Considerations
Stacking
Some states allow "stacking" — combining UM/UIM coverage from multiple vehicles on your policy to increase your available limits. If you have two cars insured with $100,000 UM each, stacking gives you $200,000 in coverage.
Hit-and-Run Claims
Most policies cover hit-and-run accidents under UM coverage, but they require:
- A police report filed within 24 hours
- Physical contact between your vehicle and the fleeing vehicle (some states)
- No identification of the other driver
Subrogation
After paying your UM claim, your insurer may pursue the uninsured driver to recover the money. This does not affect your settlement.
Protect Yourself Going Forward
- Always carry UM/UIM coverage — it is inexpensive relative to the protection it provides
- Match your UM/UIM limits to your liability limits
- Consider stacking if your state allows it
- Check your policy annually to confirm coverage is active
