Is Massachusetts an At-Fault or No-Fault State?

Yes — Massachusetts is a no-fault state. Your own insurer pays your injury costs first, whoever caused the crash.

Fault system
No-fault

PIP pays your first $8,000 of losses regardless of fault, and the at-fault driver is exempt from tort liability to that extent. You can sue for pain and suffering only if reasonable medical expenses exceed $2,000, or the injury causes death, loss of a body member, permanent and serious disfigurement, certain loss of sight or hearing, or a fracture.

Comparative negligence rule
Modified comparative — 51% bar

You can recover if your negligence was not greater than the total negligence of those you sue — so at 50% or less. Your damages are reduced by your share of fault.

PIP minimum limit
$8,000

How Massachusetts compares with every other state

What the fault rule decides

Being a no-fault state changes who pays first, not who was wrong. Your own insurer covers your medical bills and lost income up to the limit on your policy, whoever caused the crash, and the fight about blame happens later or not at all. Only 9 of the 51 jurisdictions on this site work this way, which is why advice written for the rest of the country — sue the other driver, let their insurer pay your bills — quietly does not apply here.

Modified comparative fault turns the case into a percentage. On a hypothetical $100,000 of damages — arithmetic, not a figure from Massachusetts law — being 20% to blame leaves you $80,000, and being 40% to blame leaves you $60,000. Cross the line at 51% and the award is not reduced, it is gone. 24 of the 50 jurisdictions on this site draw the line in the same place, and the whole dispute after a serious crash tends to be about which side of it you land on.

The $8,000 of personal injury protection is the money that moves first, before anyone argues about blame — and it is higher than 6 and lower than 11 of the 18 that require it. Treat it as a floor rather than a budget: it is what the state makes you carry, not an estimate of what an injury costs.
