How Pennsylvania's fault system works after a car crash

If someone just hit you in Pennsylvania, the first thing to understand is that the state does not sit cleanly on either side of the no-fault versus at-fault line. Pennsylvania runs a hybrid, sometimes called choice no-fault. Your own policy pays your initial medical bills no matter who caused the crash, and separately, a choice you made when you bought that policy controls whether you can sue the other driver for pain and suffering.¹²

That choice is easy to forget and expensive to get wrong. Here is what actually applies in Pennsylvania.

Pennsylvania is a choice no-fault state

Every auto policy issued in Pennsylvania has to include first-party medical benefits, often called PIP or personal injury protection. State law sets the floor at $5,000 in medical coverage, and those benefits pay your treatment bills regardless of who was at fault.³ So the no-fault part is real. You turn to your own insurer first for medical costs, and you do not have to prove the other driver caused the crash to collect that money.

The second layer is the tort election under 75 Pa.C.S. § 1705. When you buy or renew a policy, you pick one of two options, full tort or limited tort, and that pick decides how much you can recover from the at-fault driver later.¹

The full tort and limited tort choice

Under full tort, you keep the right to seek everything: medical costs, lost wages, other out-of-pocket losses, and financial compensation for pain and suffering and other nonmonetary harm.¹ Limited tort costs less, and the tradeoff is spelled out in the statute. A limited tort driver can still recover all medical and out-of-pocket expenses, but cannot recover for pain and suffering unless the injury meets the legal definition of a "serious injury."¹

If you never made the election in writing, the law does not leave you stuck with the cheaper option. When a named insured does not respond to the insurer's notice, § 1705 says they are "conclusively presumed to have chosen the full tort alternative."¹ Full tort is the default. One caution: that default protects you only if the paperwork gap is genuine. If you signed a limited tort selection, you are bound by it.

What counts as a serious injury

For a limited tort driver, everything turns on this phrase. Pennsylvania defines a serious injury as a personal injury resulting in death, serious impairment of body function, or permanent serious disfigurement.² Notice what is absent: there is no dollar threshold and no fixed list of qualifying injuries.

Who decides whether your injury clears that bar? The Pennsylvania Supreme Court answered that in Washington v. Baxter, 553 Pa. 434, 719 A.2d 733 (1998). The court held that the trial judge decides serious injury as a matter of law only where reasonable minds could not differ; otherwise the question goes to the jury. The same decision made clear that an impairment does not have to be permanent to count as serious.⁴ A limited tort election is therefore not an automatic bar to a pain-and-suffering claim, but it does add a fight your full tort neighbor never has to have.

When limited tort does not apply

Even if you chose limited tort, § 1705(d) restores your full right to sue in several situations. You are treated as full tort if the person at fault is convicted of, or accepts Accelerated Rehabilitative Disposition (ARD) for, driving under the influence.¹ The same is true when the at-fault driver was operating a vehicle registered in another state, when the other person intended to cause the injury, and when you are hurt as an occupant of a vehicle that is not a private passenger motor vehicle, such as a bus or commercial truck.¹ Claims against a business that designs, manufactures, repairs, or services vehicles also fall outside the limited tort restriction.¹

These exceptions matter more than they sound. A drunk driver who hits you strips away the limited tort limitation entirely, which puts pain-and-suffering damages back on the table even if you bought the cheaper policy.

No-fault medical benefits and the payment deadline

Because PIP pays regardless of fault, its timing is protected by statute. Once your insurer receives reasonable proof of a covered medical bill, it has 30 days to pay. Benefits not paid inside that window are "overdue" and start accruing interest at 12% per year.⁵ If the insurer refused to pay without a reasonable basis, it can also be on the hook for your attorney fees.⁵ The statutory $5,000 minimum is only a floor; many drivers buy higher first-party limits, and larger medical coverage is worth having before you ever need it.³

Fault still decides the lawsuit

Once you move past your own PIP and pursue the at-fault driver, Pennsylvania is squarely an at-fault, comparative negligence state. Under 42 Pa.C.S. § 7102, your own share of fault reduces your recovery, and you are barred completely only when your negligence was "greater than" the combined fault of the defendants you are suing.⁶ In plain terms, you can be up to 50% at fault and still recover something, reduced by your percentage, but at 51% you recover nothing. If a jury finds you 30% responsible for a $100,000 loss, you collect $70,000.

Coverage minimums, deadlines, and getting help

Pennsylvania's minimum liability limits are low: $15,000 for bodily injury per person, $30,000 per accident, and $5,000 for property damage, written as 15/30/5.² Those minimums run out fast in a serious crash, which is why uninsured and underinsured motorist coverage matters. UM and UIM are not mandatory in Pennsylvania. Your insurer must offer them, but you can reject them in a signed writing. If there is no valid signed rejection on file, coverage defaults to your bodily injury limits.⁷

The deadline to act is firm. You generally have two years from the crash date to file a lawsuit for your injuries, and the same two-year clock applies to vehicle and other property damage.⁸ Miss it and the claim is almost always dead, no matter how strong the facts.

A few practical points. If you need the police account of what happened, you can request the Pennsylvania crash report. If your car lost market value even after a solid repair, that is a separate diminished value claim against the at-fault driver. And because the full tort versus limited tort question and the serious injury threshold can decide whether your pain-and-suffering claim survives at all, it is worth talking to a Pennsylvania attorney before you give a recorded statement or accept an early offer.
