Antique and historic vehicle registration and insurance in Massachusetts.

What makes a car an antique motor car in Massachusetts

Massachusetts General Laws c.90, §1 defines an antique motor car as a motor vehicle over twenty-five years old that is maintained solely for use in exhibitions, club activities, parades, and other functions of public interest. The RMV’s plate application restates the same test almost word for word: the vehicle must be over 25 years old, used only for those public-interest functions, including test drives to prepare for them and trips to and from repair facilities, and it cannot be used primarily to transport passengers or goods over any way. That last clause is the one owners underestimate. Age alone doesn’t qualify a car; the certified use does.

Only a vehicle that meets this definition may display an Antique registration plate, and a motorcycle is also eligible for one. At the Registrar’s discretion, a qualifying antique motor car can instead display a Year of Manufacture plate in place of the standard Antique plate. Both routes require the same underlying eligibility; they differ in what physically goes on the bumper.

Antique plates vs. Year of Manufacture plates: how they differ

An Antique plate is a new plate issued by the RMV that says “Antique” on it. A Year of Manufacture plate is different in kind: it’s a plate the applicant already owns, one that was originally issued by the Commonwealth in the vehicle’s own model year, and it gets reused rather than replaced. A YOM plate cannot be used on a vehicle with a model year of 1979 or later, because the RMV began issuing plates with green alphanumerics on a white background that year and many of those original plates are still active in circulation. A plate that reads “Antique” can never serve as a YOM plate; the two categories don’t overlap.

The RMV can approve a YOM plate for use on an antique vehicle of a different type than the one it was originally issued for, so a truck plate can end up on an antique automobile, with one exception: a motorcycle plate can only be used on a motorcycle. If two plates were originally issued in that model year but only one still exists, the RMV may approve display of just the single plate. Whichever plate you use, it must be displayed under M.G.L. c.90, §6. The current registration decal doesn’t need to be affixed to a YOM plate, but if it isn’t, it has to be carried in the vehicle and shown to a police officer on request. A YOM plate also has to be in good repair and original condition, with legible characters; any sign of repainting or alteration will get the RMV to reject it. It can contain no more than six characters, and it must be physically presented to the RMV for inspection before it’s authorized.

The usage restriction you’re certifying to, and why it matters for a claim

Getting either plate requires signing a notarized certification, in the presence of a Notary, stating the vehicle is over 25 years old and will be maintained and operated solely for exhibitions, club activities, parades, and other functions of public interest, and that it will not be used primarily for transporting passengers or goods. The permitted uses explicitly extend to test drives preparing for an exhibition, club activity, or parade, and to transportation to and from repair facilities. That’s a narrow list, and it’s a sworn statement.

This matters beyond the RMV counter. If a vehicle’s actual use diverges sharply from what was certified, that mismatch is the kind of fact pattern that surfaces after a loss, when an adjuster is reconstructing what the car was doing at the time of an accident. The cleanest way to avoid that conversation is to keep the car’s real-world use inside the same lines you certified on the application.

How registration and insurance verification actually work together

To register under an Antique or YOM plate, you either visit an RMV Service Center or mail in the completed notarized application together with a completed Registration and Title Application, and the applicable fee. The RTA has to include the insurance company’s stamp. Under RMV policy, that stamp needs to show the insurance company name printed horizontally and a three-digit insurance company code printed vertically, or an authorized representative’s signature, all within the space provided on the form. Without that stamp or signature, the RTA is incomplete.

The fees themselves are modest: a $30 registration fee and a $20 special plate fee. There’s a timing wrinkle worth knowing. Per the RMV’s Schedule of Fees, Antique, Autohome, Taxi, Trailer, and Vanity registration fees are reduced by half on or after September 1 of the registration cycle, so when you register in the year can change what you owe.

How Massachusetts insurers and CAR treat antique-plated vehicles

Once the plate is settled, the insurance side runs through Commonwealth Automobile Reinsurers, the mechanism that administers the state’s residual private-passenger auto market under the oversight of the Commissioner of Insurance. CAR assigns antique vehicles their own statistical classification, Classification Code 0483. That code isn’t cosmetic; it changes how the vehicle counts in the broader rating system.

Under CAR’s Rules of Operation, all exposures for vehicles in Classification Code 0483 are excluded from the utilization ratio calculation that measures how much of an insurer’s business runs through the voluntary market versus the residual market. Under CAR Rule 19, the Multi-Car discount requires insuring at least two private passenger vehicles with the same company, but vehicles classified as antiques are specifically excluded from counting toward that discount, even if you insure them alongside a daily driver on the same policy. If you’re weighing whether to combine an antique with other vehicles on one policy for discount purposes, the mechanics for standard vehicles are covered in insuring multiple cars and drivers on one Massachusetts policy, and the antique carve-out is the exception to keep in mind.

CAR’s private passenger residual market manual also contains a distinct Rule 42, “Specialty and Classic Cars and Motorcycles,” set apart from standard private passenger rating in Section III. It exists as its own category because these vehicles don’t rate like a daily-use car.

What to do before you register or bind coverage

Start with the plate decision, since it determines what you certify and what you can legally do with the car. If the vehicle’s model year is 1979 or later, a YOM plate is off the table and an Antique plate is the only option. If it’s older and you already hold an original plate from that model year in good, unaltered condition, a YOM plate may be available instead. Either way, be ready to sign the notarized certification honestly, since it describes the only uses the vehicle is legally permitted for.

On the insurance side, have a policy in place before you submit the RTA, since the form needs the carrier’s stamp with its three-digit code or an authorized signature before the RMV will process it. Because antique vehicles rate under their own classification and sit outside the standard multi-car discount, it’s worth getting the vehicle quoted specifically as an antique rather than assuming your existing personal auto policy’s discounts will simply extend to it.
