Do Trailers Need License Plates in Indiana? Costs, Mounting, Penalties

Yes. Under Indiana law, trailers do need license plates: nearly every trailer towed on a public road in Indiana must be registered with the BMV and display a plate on the rear.¹ Fees start at $16.35 for the lightest trailers, and if yours weighs 3,000 pounds or less you can pay a one-time $82.00 permanent registration fee and never renew again.² Skip the plate and you’re looking at a Class C infraction, a fine of up to $500, and possible impoundment.

Which Trailers Are Covered

The rule is broad. Utility trailers, boat trailers, travel trailers, enclosed cargo trailers, and flatbeds all need to be registered before they touch a public road. Indiana’s registration statute doesn’t carve out small trailers, and there is no size or weight threshold below which you can tow plate-free.¹

Two narrow exceptions exist. Disposable trailers — single-use frames built to move manufactured building sections and then discarded — don’t need to be registered.³ And if you’re an Indiana resident with a trailer registered in a non-contiguous state, you have up to 60 days before Indiana registration kicks in.⁴ Outside those, if you tow it on a public road, it needs a plate. That includes the small 4×8 utility trailer you use twice a year.

What the Plate Costs

Indiana bases trailer registration fees on declared gross weight. The BMV’s fee chart, revised January 1, 2026, sets these amounts:²

3,000 pounds or less: $16.35
3,001 to 9,000 pounds: $25.35
9,001 to 12,000 pounds: $72.00
12,001 to 16,000 pounds: $108.00
16,001 to 22,000 pounds: $168.00
Over 22,000 pounds: $228.00

When you title the trailer for the first time, add a $15.00 title fee.² Indiana also charges 7% sales tax on trailer purchases from dealers, and depending on your county you may owe a wheel tax or surtax on top. The registration fee itself is usually the smallest number on the receipt.

The Permanent Plate for Trailers 3,000 Pounds or Less

If your trailer’s declared gross weight is 3,000 pounds or less, you can pay $82.00 once and be done with renewals. Indiana has offered this permanent registration option since January 1, 2022, and it covers the life of the trailer.² No annual renewal notice, no late fees to worry about, no chance of getting pulled over next spring because you forgot.

The math favors the permanent plate quickly. At $16.35 a year for the standard renewal, the $82.00 pays for itself in roughly five years, and most utility and small boat trailers last far longer than that. Semitrailers also qualify for permanent registration at $82.00, and farm semitrailers at $41.00.² Non-semitrailers above 3,000 pounds are not eligible and stay on the annual cycle.

How the Plate Has to Be Mounted

Indiana requires one license plate on the rear of the trailer. It has to be fastened horizontally and upright, sit at least 12 inches above the ground measured from the bottom of the plate, and remain clearly visible — not blocked by tires, bumpers, spare tire racks, or other accessories.⁵ Keep it clean enough to read. A mud-caked plate is a reason for a stop.

Federal rules require a white license plate lamp on the rear of every trailer to light the plate at night.⁶ A burned-out plate light is one of the most common reasons trailers get pulled over, and it’s a five-dollar fix. Violating Indiana’s plate display rules is itself a Class C infraction.⁵

Renewing Standard Registration

Unless you paid for the permanent plate, your trailer registration expires on a schedule set by the BMV.⁷ A standard renewal covers 12 months from the current expiration. If you let it lapse, the renewal period can run anywhere from 3 to 24 months depending on when you catch up.⁸

You can renew four ways:⁹

Online through your myBMV account
By mail using the renewal notice from the BMV
By phone at 888-692-6841, using the zip code and access code from your notice
In person at any BMV branch or BMV Connect kiosk

Towing a trailer with expired tags is treated the same as towing an unregistered one. Don’t count on a grace period.

Penalties for Towing Without a Plate

Driving an unregistered trailer on a public road is a Class C infraction, with a fine of up to $500.¹ The fine is only the start. Law enforcement can impound the trailer on the spot, and you’ll owe towing and daily storage fees until you clear the paperwork. For anyone hauling for work, an impounded trailer can shut down the job.

There’s an insurance angle worth naming. Towing an unregistered trailer, or one that exceeds your vehicle’s tow rating, can give your auto insurer grounds to deny a claim if something goes wrong on the trip. Keeping the registration current protects your coverage as much as it protects you from tickets. Indiana doesn’t require a separate policy for the trailer itself — a standard auto liability policy typically extends to damage you cause to others while towing — but that same policy usually won’t pay to replace your trailer if it’s stolen from your driveway. A trailer endorsement or a separate policy fills that gap.

Homemade or Untitled Trailers

If you built the trailer yourself, or bought one that never had a title, the BMV won’t issue a plate until you obtain a special identification number, called an MVIN. This goes through the BMV Central Office rather than a local branch. You’ll need to submit:¹⁰

Application for Special Identification Number (State Form 12907)
Trailer Ownership Affidavit (State Form 43753) — a bill of sale alone is not enough for a trailer that requires a title
Physical Inspection (State Form 39530), completed by law enforcement
One original side-view photograph of the whole trailer
Receipts for materials used in construction, if applicable
$10.00 MVIN application fee

The packet is mailed to the BMV Central Office at 100 North Senate Avenue, Room N411, Indianapolis, IN 46204.¹⁰ If anything is missing, the whole packet comes back. Once the BMV assigns an MVIN, you can apply for the title and registration the normal way and receive your plate.

The same MVIN detour comes up when you buy a used trailer with no VIN, which is common with older homemade trailers changing hands. Get a proper bill of sale from the seller with both parties’ names and addresses, the trailer’s make, model, year, sale price, date, and signatures, and hold on to it — the BMV may ask for it during the title application.
