A Massachusetts at-fault accident surcharge is an increase applied to your auto insurance after an accident in which you were found at fault. It is not automatic for every accident. Under Massachusetts rules, a surcharge applies only when two things are both true, and either one can be challenged on appeal. This site covers appealing that surcharge to the Division of Insurance Board of Appeal.
When a surcharge applies — two thresholds
A motor vehicle accident is surchargeable only when BOTH are true: (1) the operator was more than 50% at fault under the Standards of Fault in 211 CMR 74.00; and (2) the insurer paid a claim of more than $1,000, excluding any deductible. If the driver was 50% or less at fault, or the paid claim was $1,000 or less excluding the deductible, the accident is not surchargeable. The appeal challenges the at-fault determination on these grounds.
The Standards of Fault are rebuttable
The Standards of Fault (211 CMR 74.04) list specific situations — such as rear-end collisions, lane changes, left turns, intersection collisions, single-vehicle accidents, and backing up — in which the operator is presumed more than 50% at fault. These are rebuttable presumptions: each one applies "unless a showing to the contrary is demonstrated by the evidence." That is what an appeal is for — showing, with facts and evidence, that the presumption should not apply to your accident.
How the appeal works
The appeal goes to the Division of Insurance Board of Appeal. It must be filed and received within 30 days of the date on your surcharge notice — a received-by deadline, not a postmark deadline — with a $50 fee mailed to At-Fault Accident Appeals, Division of Insurance, One Federal St., Suite 700, Boston, MA 02110. The Board schedules a hearing and then issues a written "Memorandum of Finding and Order." It vacates (removes) the at-fault finding if it determines you were not more than 50% at fault, or upholds it if it determines you were.
While the appeal is pending, you must keep paying any increased premium or your policy can be cancelled. If your appeal succeeds, a refund or credit follows. Surcharge points generally follow a driver for about 6 years and are tracked by the Merit Rating Board.
What preparation looks like
The most important preparation is clarity about the accident: the date and time, the exact location, road and weather conditions, what each vehicle was doing, what the other driver did, and the evidence that supports your account. A clear, specific account tied to the police report, photos, and any dashcam footage is far more persuasive than a general protest that the surcharge is unfair.
It also helps to confirm the insurer-paid claim amount, excluding your deductible. If the paid amount did not exceed $1,000, the second threshold for a surchargeable accident is not met. Until the Board rules, the surcharge stands — so meeting the 30-day deadline is essential.
