In Massachusetts, if you were driving as part of your job and were injured in an auto accident, you could not sue your employer for your injuries. What you could do is file a claim for workers’ compensation benefits with your employer’s workers’ compensation insurance carrier.

If, however, you are less than 50% at-fault for the car accident, then you could sue the driver(s) who caused the accident. You could therefore bring a claim, in addition to your workers’ compensation claim, against the person(s) who caused the accident.
