Delaware Trailer Registration: Fees, Renewal, and Inspection

Registering a trailer in Delaware means titling it first, then paying an annual registration fee that starts at $15 and rises with the trailer’s weight. On top of that, the state charges a 5.25% document fee on the purchase price or NADA book value (whichever is higher) plus a $35 title fee, so the first-year cost on even a modest utility trailer runs a few hundred dollars before you leave the DMV.

What to Bring to the DMV

Delaware law requires every trailer to hold a Delaware title before it can be registered.¹ To handle both in one visit, bring:

Proof of ownership. For a new trailer, the manufacturer’s certificate of origin. For a used one, the previous owner’s signed title.
Proof of Delaware liability insurance on the vehicle that will tow the trailer. Trailers themselves aren’t insured separately, but the DMV wants to see coverage on the tow vehicle.²
Payment for the title fee, document fee, and registration fee, all due at the same window.

If the trailer is coming in from another state, it must pass a full safety inspection before Delaware will issue a title. Any trailer over 4,000 pounds or equipped with brakes also has to clear a brake inspection.³ New residents have 60 days from moving to Delaware to register. Active military and their families keeping vehicles registered in a home state are exempt from that deadline.⁴

Registration Fees by Weight

Annual registration fees are set by gross weight under Title 21, § 2151:

1,000 pounds or less: $15 per year
1,001 to 2,000 pounds: $20 per year
2,001 to 5,000 pounds: $40 per year
Over 5,000 pounds: $40 base, plus $18 for each additional 1,000 pounds (or fraction of 1,000) above 5,000

Those amounts come straight from the state fee schedule.⁵⁶

Title and Document Fees

Registration is only part of the bill. The document fee is 5.25% of the purchase price or NADA book value, whichever is greater, with an $8 minimum.⁵ It functions like a sales tax and applies to both new and used trailers. On a $5,000 utility trailer, that’s $262.50.

Title fees sit on top of that:

Title without a lien: $35
Title with a lien: $55

These figures were last updated effective October 2025.⁵ All in, a $5,000 trailer with no lien runs roughly $312 in title and document fees before the annual registration is even added.

How Long Registration Lasts and How to Renew

Delaware trailer registration is unusually flexible on term. You can register for 6, 12, or 24 months. Brand-new current-model-year trailers weighing 10,000 pounds or less can be registered for up to 7 years at once, with the fee calculated by multiplying the annual rate by the number of years chosen.⁷

If you’d rather have the trailer’s registration expire the same month as your tow vehicle’s, register the trailer for 1 to 12 months (prorated) and pay a $3 service fee to align the two dates.⁷

The DMV sends automated renewal reminders by email or phone at 90, 60, and 30 days before expiration if you’ve supplied contact information. Renewals can be handled by mail, online, or in person, and every DMV location offers a drive-through window for cash, check, or card payments.² Registration expires at midnight on its final day, and pulling the trailer after that point without renewing is illegal.

Inspection and Brake Rules

Whether your trailer needs an ongoing inspection depends on weight. Trailers with a gross weight of 4,000 pounds or less that aren’t required to have brakes are exempt from inspection.⁸ Once a lighter trailer is titled here, subsequent renewals don’t require inspection.³

Anything over 4,000 pounds has to pass a brake and safety inspection every two years.³ Delaware law also prohibits operating a trailer over 4,000 pounds at speeds above 10 miles per hour unless it has brakes controlled from the tow vehicle.⁹ Practically, any trailer above that threshold needs working brakes to be road-legal.

All trailers, regardless of weight, need working brake lights, tail lights, turn signals, and reflectors to stay legal on the highway.

Homemade Trailers

If you built the trailer, there’s no manufacturer’s title to hand in, so you’ll go through a VIN assignment first. Schedule a VIN inspection with a local law enforcement agency or a certified VIN inspector. Before the appointment, weigh the trailer at a public scale and collect receipts for every major component you bought: frame, axle, wheels, lights, and similar parts. Those receipts stand in as proof of ownership.

The inspector checks that the trailer has functioning brake lights, turn signals, tail lights, reflectors, a license plate light, safety chains, a coupler, proper tires, and fenders. If it passes, the inspector assigns a VIN and signs the inspection forms.

You then have 30 days to bring the signed forms, receipts, VIN plate, proof of insurance on the tow vehicle, and a valid ID to a DMV office. Title and plates get issued at that visit.

Buying or Selling a Used Trailer

When you buy a used trailer already titled in Delaware, you have 30 days to apply for a new certificate of title. Extensions are granted only for extraordinary circumstances and need the DMV Director’s approval.¹⁰

If the seller hasn’t already transferred the old plates to another vehicle, a combined transfer of title and registration costs $35, with no additional inspection or registration fee required. New title and registration documents come out of that streamlined process.¹⁰ If the seller already reassigned the plates, you go through the full registration process, which means paying the weight-based registration fee and, if the trailer exceeds 4,000 pounds, submitting it for inspection.

Selling a trailer carries its own duty. Under § 2502, the seller has to endorse the buyer’s name, address, and the date of transfer on the registration card and send it to the DMV immediately.¹¹ The DMV also accepts a Report of Sale form, which flags the vehicle record as transferred but does not by itself change legal ownership. If it’s submitted with incomplete information, the seller stays on the hook for the trailer.¹²

Farm Trailer Options

Farmers who earn at least $1,000 a year from the operation and own or rent at least 10 acres of actively farmed land can register trailers under two special categories.¹³

FT tags carry a reduced registration fee. The trailer has to be used only for farm operations or personal use, never for commercial hauling.
FV tags waive the inspection requirement, but the trailer can only travel on public roads within a 20-mile radius of the farm and cannot be used for any commercial purpose.

Neither program is a full exemption. You still register and pay a fee; the fee is just lower, and FV tags skip inspection.¹³ Renting the trailer out or hauling for pay disqualifies you from both.

Penalties for Skipping Registration

Fines are steeper than the typical traffic ticket. A new resident who misses the 60-day registration window faces a first-offense fine of $400 to $600. A second offense climbs to $800 to $1,200 and can include 10 to 30 days in jail.⁴

Operating an unregistered trailer on a public road is a separate violation under § 2115, which also prohibits knowingly letting someone else do so. Fines are set by the court.¹⁴

Tampering with plates is treated most seriously of all. Removing a plate, attaching one not authorized for that trailer, or altering a plate to misrepresent the trailer’s identity is a misdemeanor punishable by a fine of $57.50 to $575, imprisonment of 30 days to 6 months, or both.¹⁵
