Failure to Wear a Seat belt in a Massachusetts Auto Accident Cannot Be Used as Evidence
If you are injured in a car crash in Massachusetts, the fact that you were not wearing your seat belt does not constitute negligence (fault) on your part. So, if are injured in the crash and bring a claim against the at-fault driver, the fact that you were not wearing your seat belt is inadmissible at trial and cannot be used as evidence.
This law is found at M.G.L. c. 90 § 13A.
