Key Takeaways:
- “UM” coverage can pay for injuries when the at-fault driver has no insurance or flees the scene, while “UIM” coverage steps in when that driver’s limits run out.
- “Stacking” combines coverage limits across vehicles, although many Pennsylvania drivers waive it by signing a form when they buy their policies.
- Quick notice to the insurer, thorough medical records, and a close look at the policy language can protect the value of a UM or UIM claim.
Chester County car accident lawyers help injured drivers recover compensation when the at-fault motorist carries no insurance or not enough to cover the damage. In those situations, Uninsured Motorist (UM) and Underinsured Motorist (UIM) coverage on the injured person’s own policy may pay for medical bills, lost wages, and, in many cases, pain and suffering. “Stacking” can multiply those limits, and experienced lawyers can review the policy, deal with the insurer, and challenge low offers.
What Are UM and UIM Coverages in PA?
Pennsylvania requires only $15,000 per person in bodily injury liability, which often falls short of fully paying a serious injury. Picture a West Chester commuter with $60,000 in medical bills after a crash caused by a driver carrying that minimum. Once the at-fault insurer pays its limit, the underinsured motorist coverage Pennsylvania policies include can pay the rest, up to the UIM limit. Insurers must offer both coverages, although drivers may reject them in writing.
When Do These Coverages Apply?
PennDOT recorded 109,515 reportable crashes across Pennsylvania in 2025. When the driver at fault in accidents like those has no insurance, UM coverage applies, while UIM coverage kicks in after an insured driver’s limit runs out. This protection often follows the policyholder, so an uninsured driver accident Chester County residents face on Route 202 may qualify whether they were driving, walking, or biking.
What Is Stacking, and Did You Waive It?
When it comes to “stacking” coverage, PA law allows drivers to waive it for a lower premium, but only by signing a specific rejection form. Stacking multiplies UM and UIM limits by the number of vehicles on a policy. A household with three cars and $50,000 in UIM coverage on each, for example, could reach $150,000.
How Do You File a UM/UIM Claim?
The first step is written notice to that driver’s own insurer, along with the police report. Next, the injured driver should gather their medical records and proof of lost wages (if applicable) to show the insurer what the claim is worth. In a UIM claim, many policies also require the carrier’s consent before any settlement with the at-fault driver.
What if the Insurer Disputes Your Claim?
Disputes often center on fault, medical treatment, or whether a stacking waiver holds up. Many UM/UIM Pennsylvania policies send these disagreements to arbitration, although others allow a lawsuit in the Chester County Court of Common Pleas at the Justice Center in West Chester. When an insurer denies, or delays payment without a reasonable basis, Pennsylvania’s “Bad Faith Law” allows policyholders to seek interest, lawyers’ fees, and “punitive” damages.
Frequently Asked Questions (FAQs):
Does UM coverage apply to a hit-and-run crash?
Yes, Pennsylvania treats an unidentified hit-and-run vehicle as uninsured. The crash must be reported to police, and the insurer generally needs notice within 30 days.
Can someone hit by an uninsured driver still sue that driver?
Yes, although anyone hit by an uninsured driver in PA may struggle to collect a judgment from someone without insurance.
Does UM coverage protect family members in the household?
Many policies extend UM and UIM coverage to relatives who live in the same home. As a result, a relative riding in a friend’s car may still have protection under the household policy.
