Who Is at Fault? Massachusetts Modified Comparative Negligence and Motorcycle Crashes

After a crash, the other driver's insurer often has one goal: pin enough blame on the rider to pay little or nothing. Understanding the Massachusetts fault rule keeps you from accepting a bad answer.

Modified comparative negligence, explained

Massachusetts uses modified comparative negligence with a 51 percent bar. You can recover if you are not more than 50 percent at fault, reduced by your share. If your damages are 100,000 dollars and you are found 30 percent at fault, you can still recover 70,000. But if you are found 51 percent or more at fault, you recover nothing. A split-fault wreck is not worthless.

The bias riders face

Motorcyclists are often blamed by default. Witnesses and even officers can assume the rider was speeding or weaving. That is why scene evidence, photos, and independent witnesses matter so much. Fault is argued, not assumed, and good evidence shifts the argument and your share of it.

Common shared-fault situations

Left-turn crashes, lane-change collisions, and intersection wrecks frequently involve disputes over who had the right of way and who could have avoided the crash. Helmet use, lane position, and visibility all get raised. Because the 51 percent bar can wipe out a recovery entirely, keeping your share of fault down is not academic. A clear record of the other driver's error is your best protection.
