Maine trailer registration requires the title, proof of ownership, and a completed process sent to the Bureau of Motor Vehicles

To register a trailer in Maine, you submit an process to the Maine Bureau of Motor Vehicles (BMV) along with proof of ownership and payment. The process differs slightly depending on whether your trailer is new, used, or has an out-of-state title. Most trailers registered in Maine must display a registration plate, and the registration is valid for one year from the date of issue.

You do not need to pass a vehicle inspection for trailer registration in Maine, which simplifies the process compared to registering a car or truck. However, you do need to establish ownership through a title or bill of sale, and you must pay the registration fee based on the trailer's gross vehicle weight rating (GVWR).

Key Takeaways

  • Maine requires a completed process (Form 1-W for trailers), proof of ownership, and payment to the BMV to register a trailer.
  • Registration fees are based on your trailer's gross vehicle weight rating, not its age or condition.
  • You can register a trailer in person at any BMV office, by mail, or through an authorized agent such as a town clerk's office.
  • Trailers with out-of-state titles must be titled in Maine before registration, which requires an additional form and a small fee.
  • Maine registration plates must be displayed on the rear of the trailer and are valid for one year.

What documents you need to bring or submit

The Maine BMV requires a completed process form, proof of ownership, and payment. The process form for a trailer is Form 1-W, which you can read from the Maine BMV website or pick up at any BMV office. You will also need proof of ownership, which is either a Maine title, an out-of-state title, or a bill of sale if the trailer is new and has never been titled.

If you are registering a trailer with a Maine title, bring the title itself along with the completed Form 1-W and your payment. If the trailer has an out-of-state title, you will need to title it in Maine first using Form 1-T (process for Title). This step adds a small fee but is required before you can register. If the trailer is new and came with a bill of sale from the dealer, that bill of sale serves as proof of ownership for the initial registration.

You will also need to know your trailer's gross vehicle weight rating (GVWR), which is the maximum weight the trailer can safely carry including its own weight. This number is stamped on the trailer's frame or listed in the manufacturer's documentation. The GVWR determines your registration fee.

Registration fees based on trailer weight

Maine registration fees for trailers are calculated by weight category. Trailers under 1,500 pounds GVWR have one fee, trailers between 1,500 and 3,000 pounds have another, and trailers over 3,000 pounds have a higher fee. The exact amounts vary slightly year to year, so you should check the current fee schedule on the Maine BMV website or call the BMV directly at 207-624-9000 to confirm the current cost for your trailer's weight class.

The registration is valid for one year from the date of issue. When your registration expires, you will need to renew it by submitting a renewal form and payment to the BMV. Renewal can be done by mail, in person, or through an authorized agent.

Where to register your trailer

You have three options for registering your trailer in Maine: in person at a BMV office, by mail, or through an authorized agent. The fastest route is usually an authorized agent, which includes most town clerk offices throughout Maine. Town clerks can process trailer registrations on the spot and issue your plate when ready, so you can leave with your registration complete.

If you prefer to register by mail, send your completed Form 1-W, proof of ownership, and payment to the Maine Bureau of Motor Vehicles, 101 Hospital Street, Augusta, Maine 04330. Processing by mail typically takes one to two weeks. You can also visit a BMV office in person; the main office is in Augusta, and there are regional offices in other locations. Check the BMV website for office hours and locations near you.

Registering a trailer with an out-of-state title

If your trailer has a title from another state, Maine requires you to title it in Maine before you can register it. This is a separate step from registration and involves submitting Form 1-T (process for Title) along with your out-of-state title, proof of ownership, and a small titling fee. Once Maine issues you a Maine title, you then proceed with registration using that new title.

The titling process protects Maine's interest in the trailer and ensures the title is clear of liens or other claims. If your out-of-state title shows a lien (a loan against the trailer), you will need to provide proof that the lien has been satisfied before Maine will issue a new title. This might be a lien release letter from the lender or a notation on the title itself showing the lien is paid off.

Registration plates and display requirements

Once your trailer is registered, the Maine BMV will issue you a registration plate. This plate must be mounted on the rear of the trailer in a location where it is clearly visible. The plate displays your registration number and the year of registration. Maine does not require a front plate on trailers, only a rear plate.

Your registration certificate (the paper document) should be kept in a safe place at home or in your vehicle. You do not need to carry it with you while towing, but it is proof of your registration if you are stopped by law enforcement. The registration plate itself is the visible proof that your trailer is registered.

Renewing your trailer registration

Trailer registration in Maine is valid for one year from the date of issue. When your registration is about to expire, the BMV will send you a renewal notice in the mail. You can renew by mail, in person at a BMV office, or through an authorized agent such as a town clerk. Renewal requires a completed renewal form, payment of the registration fee, and proof that your trailer still exists and is in your possession (usually just your signature on the form).

If you renew before your registration expires, your new registration begins on the expiration date of the old one, so you do not lose any time. If you let your registration lapse, you cannot legally tow the trailer on public roads until you renew it. Renewing late does not add a penalty fee in Maine, but you should renew promptly to avoid driving an unregistered trailer.

Special cases: new trailers and inherited trailers

If you purchase a new trailer from a dealer, it will come with a bill of sale and possibly a manufacturer's certificate of origin. Use the bill of sale as proof of ownership to register the trailer. You do not need a title for a brand-new trailer; the bill of sale is sufficient for your first registration. Once registered, the BMV will issue you a title.

If you inherit a trailer, you will need to obtain a title in your name. This usually requires the previous owner's title, a bill of sale or affidavit of inheritance, and proof of your relationship to the previous owner. Contact the Maine BMV for specific requirements for inherited property, as the process can vary depending on whether the previous owner's estate has been settled.

Frequently Asked Questions

Do I need to inspect my trailer before registering it in Maine?

No. Maine does not require a safety inspection for trailers before registration. You only need proof of ownership, a completed process, and payment. This is different from registering a car or truck, which must pass an inspection.

Can I register a trailer if I do not have a title?

If the trailer is new and came with a bill of sale from the dealer, you can register it using the bill of sale as proof of ownership. If the trailer is used and you have no title or bill of sale, you will need to contact the Maine BMV about obtaining a title through an affidavit or other documentation. This process varies by situation.

How long does it take to register a trailer in Maine?

If you register in person at a town clerk's office or BMV office, you can complete registration the same day and receive your plate when ready. If you register by mail, processing typically takes one to two weeks. The time depends on how quickly the BMV receives and processes your paperwork.

What if my trailer is too heavy to register as a regular trailer?

Trailers with a GVWR over a certain threshold may require a commercial registration or a special permit depending on how you plan to use them. Contact the Maine BMV to discuss your trailer's weight and intended use; they can tell you whether a standard registration applies or whether you need a different type of registration.

Can I register my trailer at a town clerk's office?

Yes. Most town clerk offices in Maine are authorized agents for the BMV and can process trailer registrations. This is often the fastest and most convenient option because you can complete registration in one visit and receive your plate when ready.
