If you’re injured by an uninsured or underinsured driver in Pennsylvania, you may recover through your own auto policy. Even if you weren’t at fault, 75 Pa.C.S. § 1731 requires insurers to offer UM/UIM; you may claim these benefits if you purchased them.
UM and UIM are distinct coverages with different triggers; depending on your policy, stacking can multiply your limits and change your total available recovery, and a car accident lawyer can review those layers to clarify how much compensation is actually accessible under your specific policy.

Key Takeaways for Pennsylvania Uninsured Motorist Coverage
- Uninsured motorist (UM) coverage protects you when an at-fault driver has no insurance, while underinsured motorist (UIM) coverage pays when their insurance limits are insufficient for your injuries.
- Recent Pennsylvania legislation (SB 578, 2025) may prohibit UM/UIM stacking on new policies but existing policies with stacking maintain equivalent limits at renewal—review your policy terms carefully.
- You file UM/UIM claims with your own insurer, and it may dispute them; 42 Pa.C.S. § 8371 provides a statutory bad faith remedy.
- Many UM/UIM policies require arbitration by contract, creating a unique claim process that is different from standard third-party injury claims.

What Is Uninsured Motorist (UM) Coverage?
UM protects you when the at-fault driver has no insurance. UM coverage pays for your bodily injury losses, including injuries, lost wages, and pain and suffering when the person who caused your accident cannot be held financially responsible through their own insurance, and incidents involving secondary car accidents can also fall under this protection when they stem from the same uninsured driver’s negligence.
75 Pa.C.S. § 1731 requires all insurers to offer UM coverage to policyholders. You can reject this coverage with a valid written waiver, but doing so eliminates critical protection. Given that many Pennsylvania drivers operate vehicles without insurance, rejecting UM/UIM coverage is strongly inadvisable without fully understanding the financial risks.
What UM Coverage Protects
UM can also apply beyond a crash with an uninsured driver. It can cover hit-and-run crashes where the other driver hits you and flees. Coverage for hit-and-run or phantom vehicle incidents depends on policy terms; many policies require corroborating evidence such as a witness or physical proof. Check your policy.
UM coverage also applies when you’re injured by a driver whose insurance company becomes insolvent before paying your claim. The coverage typically addresses bodily injury losses but does not extend to property damage unless specifically included in your policy. Single-vehicle accidents you cause yourself are not covered by UM.
Pennsylvania UM Coverage Requirements
When you buy auto insurance in Pennsylvania, your insurer must offer UM/UIM and let you choose limits up to your liability limits. You may select lower limits or reject UM/UIM with a valid written waiver.
Pennsylvania’s minimum liability limits are $15,000 per person, $30,000 per accident for bodily injury, and $5,000 for property damage, defined as financial responsibility in 75 Pa.C.S. § 1702. UM/UIM limits generally match these minimums unless you purchase higher limits. However, you can and should purchase higher UM limits. Coverage options of $100,000, $250,000, or $500,000 per person provide much more realistic protection for serious injuries. A single emergency room visit can cost $5,000 to $10,000, and moderate injuries requiring surgery easily exceed $50,000 in total damages.
What Is Underinsured Motorist (UIM) Coverage?
UIM fills the gap when the at-fault driver’s insurance limits are insufficient for your injuries. While UM coverage addresses drivers with no insurance at all, UIM coverage tackles the equally common problem of drivers carrying only Pennsylvania’s inadequate minimum coverage amounts, and the recent surge in car accidents makes this protection even more important for anyone facing serious medical bills and long-term losses.
How UIM Coverage Works
UIM applies when your total damages exceed the at-fault driver’s liability limits and pays up to your UIM limit. The coverage triggers when your total damages exceed the at-fault driver’s liability limits. Your UIM coverage then pays the difference between the at-fault driver’s limits and your damages, up to your UIM policy limit.
Consider this example: You suffer $80,000 in damages from an accident caused by a driver with Pennsylvania’s minimum $15,000 liability coverage. The at-fault driver’s insurer pays their $15,000 policy limit. If you carry $100,000 UIM coverage, your own insurer pays the remaining $65,000, bringing your total recovery to the full $80,000.
Without UIM coverage in this scenario, you would recover only $15,000 despite having $80,000 in legitimate damages.
Why UIM Coverage Is Essential in Pennsylvania
Many Pennsylvania drivers carry only the state minimum $15,000, believing they’ve satisfied their legal obligation. When these drivers cause serious accidents, their minimal coverage proves inadequate for compensating actual injuries.

How to File a UM/UIM Claim With Your Own Insurance
Filing a UM/UIM claim differs from a standard third-party injury claim. You’re dealing with your own insurance company, but that doesn’t guarantee a smooth process, after getting into a car accident, because insurers often scrutinize these claims more aggressively than people expect.
Discovering the Other Driver Is Uninsured or Underinsured
First, confirm the at-fault driver’s insurance status. For uninsured drivers, the police report typically indicates “no insurance” or “unable to verify insurance.” Some drivers present fake or lapsed insurance cards; you may learn later that the policy didn’t exist or had lapsed.
For underinsured drivers, obtain the at-fault driver’s insurance information and contact their liability carrier to confirm policy limits. Compare those limits to your damages to determine whether UIM coverage might apply.
Reviewing Your Own Auto Insurance Policy
Locate your policy declarations page showing your UM/UIM limits. Verify whether your coverage is stacked or non-stacked, as this distinction dramatically affects available limits for serious injuries.
Key policy documents to locate:
- UM/UIM selection or rejection forms
- Stacking waiver (if any)
- Arbitration clause and procedures
- Consent-to-settle provision
- Household vehicle exclusion language
- Suit-limitation or arbitration-demand deadlines
If you have stacked coverage, count the vehicles on your policy. If you rejected or never purchased UM/UIM, these benefits are unavailable for this accident. You cannot buy UM/UIM coverage after an accident occurs.
Notifying Your Insurance Company
Contact your insurance company promptly to report your UM or UIM claim. Provide written notice, including the accident date, location, description, police report, the other driver’s information or lack thereof, and details about your injuries and treatment.
Your insurer assigns a UM/UIM adjuster to investigate liability, coverage, and damages. The insurer examines your injuries through a medical records review and assessment of treatment necessity. Your insurer may request a recorded statement; consider speaking with an attorney before giving one.
Your insurer will likely request authorization for medical records. Limit these authorizations to accident-related treatment rather than signing blanket authorizations. The insurer may demand an independent medical examination where their chosen doctor evaluates your injuries.
Even though you’re claiming from your own insurer, it may dispute your claim. 42 Pa.C.S. § 8371 provides a statutory bad-faith cause of action with remedies including punitive damages, interest, and attorney fees when insurers act in bad faith, while the duty of good faith arises under Pennsylvania common law.
Include with your notice when available:
- Police report number and agency
- Photos/video of damage and scene
- Names of all treating providers to date
- Itemized medical bills and wage-loss proof
- At-fault driver’s insurer and claimed limits (if known)
- Your policy declarations page
Settlement Negotiations and Beyond
After investigating your claim, your insurer makes a settlement offer. Initial offers are often inadequate. Provide comprehensive medical bills, records, and wage loss documentation supporting your damages. Consider hiring an attorney to handle negotiations, as insurers may take represented claimants more seriously.
If negotiations fail, many policies require contractual arbitration. Arbitration awards are typically binding with only limited grounds to vacate under Pennsylvania arbitration law, such as fraud, evident partiality, or procedural misconduct. If your policy lacks an arbitration clause, you may file suit in court.
Court review of arbitration awards is limited to narrow statutory or common-law grounds, not a trial de novo. If your insurer acted in bad faith during the claim process, you may pursue damages beyond your policy limits, including punitive damages, interest, and attorney fees under 42 Pa.C.S. § 8371.

Stacking vs. Non-Stacking Coverage in Pennsylvania
The difference between stacked and non-stacked UM/UIM coverage can mean hundreds of thousands of dollars in additional compensation for serious injuries. However, recent legislative changes may affect stacking availability for new policies, and car accident lawyers often review these policies to determine how much coverage is actually available when injuries exceed the at-fault driver’s limits.
What Is Stacking?
Stacking under 75 Pa.C.S. § 1738 multiplies your UM/UIM coverage limits by the number of vehicles insured on your policy. Stacking can apply across vehicles on the same policy and, in some cases, across multiple policies, depending on policy language and waivers.
If you have three vehicles with $100,000 UM/UIM coverage each and you carry stacked coverage, you have $300,000 total UM/UIM coverage available.
Stacking has traditionally been the default in Pennsylvania; it applies unless you validly waive it in writing. The waiver must be clear and conspicuous, informing you of your right to stack and the premium difference.
Important Legislative Change: Recent Pennsylvania legislation (Senate Bill 578, 2025) prohibits UM/UIM stacking on new policies issued after enactment. However, existing policies with stacking maintain equivalent unstacked limits at renewal. For example, if you currently have $100,000 stacked across three vehicles ($300,000 total), your policy at renewal provides $300,000 unstacked coverage. Consumers should review their policy terms carefully at renewal to understand how this change affects their coverage.
Consider a catastrophic injury scenario where you suffer $250,000 in damages. With stacked coverage on three vehicles at $100,000 each, you can recover the full $250,000. With non-stacked coverage, you recover only $100,000. Stacking provides an additional $150,000 compensation.
Non-Stacking Coverage Limitations
Non-stacked coverage limits your recovery to the stated UM/UIM limit on one vehicle regardless of how many vehicles you insure. This reduces premiums but dramatically limits available coverage for serious injuries.
Non-stacking may be acceptable if you insure only one vehicle or carry very high UM/UIM limits (e.g., $500,000+ per vehicle).
Making the Stacking Decision
For policyholders with existing stacked coverage, understanding how recent legislative changes affect renewal terms is critical. Given that many Pennsylvania drivers carry no insurance and many more carry only inadequate minimums, maintaining adequate UM/UIM limits—whether through stacking or equivalent unstacked amounts—remains essential.
You cannot add stacking retroactively after an accident occurs. Review your coverage carefully at each renewal to understand your available limits.
Common UM/UIM Claim Problems and Solutions
Insurance companies deny or dispute UM/UIM claims for various reasons, many of them improper.
Claim Denials
Insurers sometimes deny UM claims by disputing the at-fault driver’s fault. Provide the police report showing the other driver’s fault and any witness statements. Some insurers assert that your policy lapsed or wasn’t in effect at the accident time. Obtain your policy declarations page and payment records proving coverage.
Lowball Settlement Offers
Insurance companies routinely make inadequate initial settlement offers. Don’t accept the first offer. Obtain all medical records and bills documenting your injuries. Get your treating physician’s opinion on permanency and future treatment needs. Hire an attorney for serious injuries.
Delay Tactics
Some insurers use delay tactics, including slow investigations and repeatedly requesting the same documents. Document all communications and delays. Send written demands with specific deadlines. Consider whether delays constitute bad faith under 42 Pa.C.S. § 8371, and personal injury claims often require pushing back firmly when an insurer drags its feet or refuses to evaluate evidence in good faith.
Stacking Disputes
Insurers sometimes dispute stacking availability by claiming you waived this right. Review the waiver language carefully—many waivers are invalid under Pennsylvania law. An attorney can challenge invalid waivers through litigation if necessary.
FAQ for Pennsylvania Uninsured Motorist Coverage
What is the household-vehicle exclusion and can it reduce my coverage?
Some policies exclude UM/UIM coverage for injuries involving a household vehicle that is not listed on the policy. Recent Pennsylvania cases may limit enforcement if the clause functions like an improper stacking waiver—review your policy language and waivers.
Will my insurance rates go up if I file a UM claim?
Filing a UM claim typically does not increase your rates because you weren’t at fault. You’re simply using coverage you paid for.
How much UM/UIM coverage should I have?
Purchase UM/UIM coverage at least equal to your assets. Limits of $100,000, $250,000, or $500,000 per person provide realistic protection for serious injuries given modern medical costs.
What is a consent-to-settle clause and why does it matter for UIM?
Many UIM policies require you to obtain your insurer’s consent before settling with the at-fault driver so the insurer can preserve subrogation rights. Give written notice and follow any substitution-of-payment procedures.
Am I covered by UM/UIM as a pedestrian, cyclist, or passenger in someone else’s car?
Named insureds and resident relatives typically have UM/UIM even when not in their own car. Guests may access the host vehicle’s coverage first, then their own policy, per priority rules and policy language.
Do I need a lawyer for a UM claim?
For serious injuries with damages exceeding $50,000, permanent disabilities, or disputed claims, hiring an attorney protects your rights. Attorneys negotiate lien reductions, handle arbitration, and fight bad faith insurance practices.
Do health insurers, Medicare/Medicaid, or workers’ comp get reimbursed from my UM/UIM settlement?
Medical payers often assert liens or rights of reimbursement. Resolve statutory and contractual liens such as Medicare’s conditional payments before disbursement to avoid penalties.
