Pennsylvania Car Accident Laws

Pennsylvania is one of only a handful of "choice" no-fault states, alongside Kentucky and New Jersey. Unlike most rules on this page, this one isn't set by your accident — it was set months or years earlier, when you bought your insurance policy.

The most important decision affecting your claim may already have been made — on a form you filled out when you bought insurance, long before any accident.

Statute of limitations: 2 years

Under 42 Pa. Cons. Stat. §5524(2), you generally have two years from the date of the accident to file a personal injury lawsuit. This deadline applies regardless of your tort election (see below) — fault or no-fault, the filing clock is the same.

Limited tort vs. full tort: the choice that matters most

When you buy auto insurance in Pennsylvania, you choose between two options under 75 Pa. Cons. Stat. §1705:

If you don't know which you have, it's worth checking your policy before you assume what you can claim — this single election can change the entire shape of your case.

Fault rule: modified comparative negligence, 51% bar

For claims that do proceed against an at-fault driver, Pennsylvania applies modified comparative negligence under 42 Pa. C.S. §7102: you can recover damages if you're found 50% at fault or less, reduced by your percentage of fault. At 51% or more, you recover nothing.

Insurance: PIP minimums and liability

Pennsylvania requires at least $5,000 in first-party medical benefits (PIP) regardless of your tort election, plus liability coverage for bodily injury and property damage. Because minimum PIP is relatively low, it's worth checking whether it would realistically cover your medical costs after a serious crash.

How this plays out in a real claim

Take an intersection collision where fault is genuinely disputed. If an insurer or court assigns you 40% of the blame, Pennsylvania's rule still lets you recover 60% of your damages, and even at exactly 50% you still recover half. But at 51% or more, the claim is barred entirely — not reduced, eliminated. That one-point difference between 50% and 51% is exactly why insurers have a real incentive to push a borderline case just over the line rather than simply discount what they pay.

A mistake worth avoiding in Pennsylvania

Because a single percentage point at the 51% threshold can be the entire difference between a reduced payout and nothing at all, careless statements at the scene or to an adjuster carry more weight here than in a pure comparative state. Avoid speculating about fault, even casually, until the full picture — police report, witnesses, any available footage — is in front of you.

If a government vehicle or agency was involved

Pennsylvania partially waives sovereign immunity for negligence claims, including car accidents involving a government-owned vehicle, under the Sovereign Immunity Act (42 Pa. Cons. Stat. §8522) and the Political Subdivision Tort Claims Act (42 Pa. Cons. Stat. §8541) for local governments. You must generally file a formal notice of claim within six months of the injury, and damages are capped at $250,000 per person and $1,000,000 per incident — well below what an uncapped claim against a private driver might be worth.

If the crash resulted in a death

Pennsylvania gives two years from the date of death for a wrongful death claim (42 Pa. C.S. §5524(2) / §8301), limited strictly to the surviving spouse, children, and parents — siblings and grandparents have no standing. For the first six months after death, only the estate's personal representative may file; after that, any eligible beneficiary can bring the claim themselves. Recovery passes directly to those beneficiaries by Pennsylvania's intestacy formula rather than through the estate, which matters if the deceased had debts.

Uninsured/underinsured motorist coverage

Pennsylvania doesn't require UM/UIM coverage — insurers must offer it, and you can reject it in writing (75 Pa. C.S. §1731). If you own multiple vehicles, stacking (multiplying your UM/UIM limit by the number of insured vehicles) applies automatically unless you separately waive it in writing (§1738). A notable wrinkle from Pennsylvania case law: insurers can still deny stacked coverage under a “household vehicle exclusion” if you'd waived UM/UIM entirely on the specific vehicle you were riding in at the time of the crash (Erie Ins. Exchange v. Mione, 2023) — there has to be something to stack onto in the first place.

Beyond the deadline and the fault rule

The statute of limitations and the fault rule above decide whether you have a claim and how much of it survives — they don't decide what the claim is actually worth, or whether it's worth handling yourself. For that, see our guides on what affects a settlement, who pays your medical bills while a claim is pending, and whether Pennsylvania law makes a lawyer worth it for your specific situation.

When it's worth talking to someone

Between the tort election, the 51% fault bar, and a modest PIP minimum, Pennsylvania has more moving parts than most states. If you're unsure which tort option you have or whether your injury meets the "serious injury" threshold, a free, no-obligation conversation can clarify quickly.
