You were hurt in an accident. But now the other driver’s insurance company is claiming you were partly to blame. Maybe you were going a few miles over the speed limit. Maybe you didn’t see the hazard in time. Whatever they’re saying, you’re wondering: does this mean I can’t recover anything? In Massachusetts, the answer is usually no — partial fault does not automatically end your case. But it can reduce what you recover, and in some situations, it can bar you from collecting anything at all. Here’s what you need to know.
What Comparative Negligence Actually Means
Comparative negligence is the legal rule Massachusetts uses to divide responsibility when more than one party contributed to an accident. Instead of treating fault as all-or-nothing, the law assigns a percentage of responsibility to each party involved.
Massachusetts follows what’s called modified comparative negligence under M.G.L. Chapter 231, Section 85. The rule is straightforward: if you were partially at fault, your compensation is reduced by your share of that fault. If you were 20% responsible for a car accident, you can still recover, but your damages are reduced by 20%.
This is different from older contributory negligence rules that some states once used, where any fault on your part could block recovery entirely. Massachusetts moved away from that approach to create a fairer system for injured people.
The 51% Rule: Where the Line Is Drawn
The most important number in comparative negligence cases in Massachusetts is 51.
Under M.G.L. Chapter 231, Section 85, you can recover compensation as long as your share of fault is 50% or less. The moment your fault reaches 51% — meaning you are more responsible for the accident than the other party — you are barred from recovering anything.
Here’s how it plays out in practice:
- You are found 20% at fault and your damages total $100,000. You recover $80,000.
- You are found 50% at fault and your damages total $100,000. You recover $50,000.
- You are found 51% at fault. You recover nothing.
The difference between 50% and 51% is not a technicality. It’s the difference between walking away with compensation and walking away with nothing. That gap is exactly where insurance companies focus their energy.
How Insurance Companies Use This Rule Against You
Insurance adjusters are trained to push your percentage of fault as high as possible. The higher they can get that number, the less they have to pay, or the better their chance of eliminating your claim entirely.
Common tactics include:
- Using your recorded statement against you to imply you were distracted or moving too fast
- Citing your location, speed, or actions just before the accident as evidence of fault
- Arguing that you failed to take reasonable precautions, such as wearing proper footwear or staying in a designated walkway
- Pointing to any prior injuries or health conditions to suggest your damages were pre-existing
You do not have to accept the insurance company’s version of events. Fault percentages are argued and negotiated, not simply handed down. Working with a Massachusetts personal injury attorney can help you challenge the evidence used to assign fault and keep your percentage as low as possible.
Real-World Examples of How Fault Gets Divided
It helps to see comparative negligence in concrete situations, because it comes up in many different types of injury claims.
Car accidents: Two drivers collide at an intersection. One ran a yellow light; the other was speeding. The jury assigns 30% fault to the speeding driver and 70% to the driver who ran the light. The speeding driver, despite being partially at fault, can still recover, with damages reduced by 30%.
Slip and fall: A grocery store has a wet floor with a warning sign posted nearby. A customer slips and falls but was looking at their phone at the time. The store is found 70% at fault for the dangerous condition; the customer is found 30% at fault for not paying attention. The customer recovers 70% of their damages.
Pedestrian accidents: A pedestrian crosses outside a crosswalk and is hit by a driver who was going well over the speed limit. Fault is divided based on the specific facts, how far outside the crosswalk, how excessive the speed, and other circumstances.
Every case turns on its specific facts. The percentages are not predetermined. They are shaped by the evidence, how it is presented, and how effectively each side argues its position.
What This Means If You Are Considering a Claim
If you were injured and you think you may have been partially at fault, do not assume your case is over. Here is what matters most:
First, do not make any statements to the other party’s insurance company without speaking to an attorney. Anything you say can be used to increase your assigned fault percentage.
Second, gather and preserve evidence as early as possible. Photos, witness information, medical records, and accident reports all matter. The stronger your evidence, the harder it is to inflate your share of fault.
Third, talk to a personal injury attorney before you settle. Insurance companies often make early settlement offers that seem reasonable but significantly undervalue your claim, and once you settle, you cannot go back.
The three-year statute of limitations for personal injury claims in Massachusetts means time matters. Waiting too long can cost you the right to file entirely.
