Comparative Negligence in Pennsylvania
Last updated June 2026
You have been injured by someone's negligence, but you were not entirely without fault either. You were distracted, or you were moving a little too fast, or you had some role in what happened. Now you are wondering: does that wipe out your claim? How much will it reduce your recovery? Pennsylvania law gives you some protection, but the rules can be counterintuitive.
Pennsylvania uses a modified comparative negligence rule. Under 42 Pa.C.S. § 7102, you can recover damages for your injuries if you are 50% or less at fault for the accident. If you are 51% or more at fault, you recover nothing. It is an all-or-nothing threshold, unlike some other states that use pure comparative negligence.
This means you can be partially at fault and still recover compensation reduced by your percentage. If you are 20% at fault, you recover 80% of your damages. If you are 50% at fault, you recover 50% of your damages. If you are 51% at fault, you recover zero.
The percentage is determined by a jury (or sometimes a judge in bench trials). The jury hears evidence about how the accident happened and assigns fault percentages based on each party's conduct.
Example one: You are in a car accident at an intersection. The other driver ran a red light, but you were exceeding the speed limit slightly. You suffer $100,000 in damages. The jury finds you 15% at fault and the other driver 85% at fault. You recover $85,000 (your $100,000 damages multiplied by 85%, the driver's percentage of fault). The driver's insurance pays you $85,000.
Example two: You are struck by a car while jaywalking at an intersection. You were not in the crosswalk. The driver was speeding but had a green light. You suffer $50,000 in damages. The jury finds you 40% at fault for jaywalking and the driver 60% at fault for speeding. You recover $30,000 (your $50,000 damages multiplied by 60%, the driver's percentage of fault).
Example three: You are in a slip and fall at a grocery store. You were not paying attention to your footing and had your phone out. The store left a spill unattended for hours. You suffer $40,000 in damages. The jury finds you 35% at fault for inattention and the store 65% at fault for negligence. You recover $26,000 (your $40,000 times 65%).
Example four: You are hit by a car while crossing the street against the signal. You run into traffic in a dangerous manner. The driver was speeding but had a legal right of way. You suffer $60,000 in damages. The jury finds you 55% at fault and the driver 45% at fault. You recover zero. The 51% threshold eliminates your claim entirely.
Fault percentages are fact questions for the jury. The evidence presented includes testimony from the parties, witnesses, accident reconstruction experts, surveillance video, police reports, and expert analysis of how the accident occurred.
The jury instruction gives the jury guidance. They are asked to consider the conduct of each party and assign percentages based on how much each party's negligence contributed to the accident. The jury instructions typically define negligence as a failure to exercise ordinary care.
Juries are instructed to consider comparative conduct fairly. If one party clearly caused the accident and the other had minor fault, the percentages should reflect that disparity. If both parties were negligent, the percentages should fairly allocate responsibility.
Jury verdicts are unpredictable. A jury might find you more at fault than you expected based on your perception of the accident. Trial is a risk. Both sides gamble on how the jury will split the fault.
Pennsylvania law changed how defendants pay damages when multiple parties are at fault. Until recently, joint and several liability meant if there were three defendants, any one of them could be forced to pay the full judgment. The defendant 10% at fault could pay 100% if the others did not pay.
The Fair Share Act changed this. Joint and several liability now applies only to defendants who are 60% or more at fault. A defendant 60%+ at fault is jointly and severally liable (can be forced to pay the full amount). Defendants less than 60% at fault are only severally liable; they pay only their percentage share.
For you as a plaintiff, this has a practical impact. If the defendant is 59% at fault and you are 41% at fault, the defendant is only liable for 59% of your damages. You have to absorb the 41% yourself. If the defendant is 61% at fault, they could be on the hook for the full 100% (though in practice they pay their insurance limits).
This rule also affects settlements. A defendant at 59% fault has less incentive to settle aggressively because they know their liability is capped at 59%. Insurance companies calculate exposure based on this threshold.
Insurance adjusters always raise comparative fault arguments during settlement talks. They argue you bear some responsibility for the accident, and therefore your recovery should be reduced. Even when liability is mostly clear, they will find some aspect of your conduct to claim contributed to the injury.
Be aware of one important limit. In Pennsylvania, failure to wear a seatbelt cannot be used against you. Under 75 Pa.C.S. § 4581(e), non-use of a safety belt cannot be considered contributory negligence and is not admissible as evidence in any civil action, so the insurer cannot reduce your recovery on that basis. Other conduct is fair game, though. If you were injured in a slip and fall while distracted, they will argue you should have been paying attention. If you were jaywalking when hit, they will argue you created the danger.
These arguments reduce settlement offers. If your damages are fairly valued at $50,000 but the insurer thinks they can convince a jury you are 30% at fault, they will offer less than $35,000. They are betting you will settle to avoid trial risk.
This is why documentation and testimony are critical. The clearer the facts show the defendant's negligence and your lack of fault, the weaker comparative fault arguments become. If the facts are murkier, comparative fault claims have more traction.
Car accident: you were speeding slightly, you ran a stop sign, or you had your phone out. Even if the other driver's conduct was worse, your conduct is compared. (One common argument is off the table in Pennsylvania: under 75 Pa.C.S. § 4581(e), failure to wear a seatbelt cannot be used as comparative fault and is not admissible at trial.) Comparative fault is almost always raised in car accident settlements.
Jaywalking: you cross against the signal or outside a crosswalk. Even if the driver was speeding or distracted, you are partly at fault for being in traffic illegally. Pedestrian accidents almost always involve comparative fault analysis.
Slip and fall: you were distracted, wearing poor footwear, running, or not paying attention. Even if the property owner was negligent, your inattention is compared. Slip and fall cases frequently reduce claims by 20-40% due to comparative fault.
Drunk or impaired driver claim: if you were drinking even moderately, the insurer will argue impairment affected your judgment or reflexes. Even if the other driver was drunk and you were sober, if you had any alcohol at all, comparative fault is raised.
Failure to mitigate: if you are injured and do not seek medical treatment, or you delay treatment, the insurer argues you failed to mitigate damages, reducing your claim value. This is not technically comparative fault, but it operates similarly.
Understanding comparative negligence changes how you present your case. You want to minimize evidence of your own negligence while emphasizing the defendant's conduct. You want strong evidence showing you acted reasonably and the defendant acted unreasonably.
If the facts show you did bear some fault, your attorney's job is to minimize that percentage. If the jury is going to find some comparative fault (and many do), you want them finding 10% not 40%. Strategic evidence presentation, expert testimony about standard of care, and clear documentation of the defendant's conduct all influence jury percentages.
Settlement negotiations involve trading off comparative fault. If the insurer thinks they can establish 30% comparative fault at trial, they will offer less. If you believe comparative fault is minimal or absent, you hold firm on settlement demands. If comparative fault is realistic, you adjust demands downward to account for it.
The 51% bar also affects settlement decisions. If comparative fault could plausibly reach 51%, the case value drops dramatically: from full recovery down to zero. This creates settlement urgency. You do not want to risk trial on a borderline fault case where a jury might find you over 50%.
If you have been injured and comparative fault is a factor, the analysis gets more complex. You need an attorney who understands how juries apply comparative negligence and who can strategically present facts to minimize your comparative fault percentage.
Document the facts clearly. Preserve evidence. Get witness statements. These all support your narrative that the defendant's negligence was the dominant cause of your injury and your conduct was reasonable.
We evaluate comparative fault early in case assessment. If your fault exposure is significant, we tell you. If it is minor or nonexistent, that is factored into settlement strategy and case valuation. Call us at 215-949-0888 to discuss your case and how comparative negligence applies to your facts.
