Connecticut antique plates are available for any vehicle at least 20 years old that has been kept in its original, unmodified condition and preserved for its historical interest. Registering under this classification caps the vehicle’s property tax assessment at $500 no matter what the car is actually worth, exempts it from emissions testing, and puts it on a separate fee schedule. In return, the car has to stay close to how the factory built it and be used as a collector piece rather than a daily driver.
Who Qualifies
Connecticut General Statutes Section 14-1 defines an antique, rare, or special interest motor vehicle as one that is at least 20 years old, preserved because of historic interest, and not altered or modified from the original manufacturer’s specifications.1Connecticut General Assembly. Connecticut Code Chapter 246 – Motor Vehicles All three conditions have to be met. A 25-year-old car driven hard as a commuter fails the preservation test. A beautifully restored car with a modern engine swap fails the modification test.
The modification standard is what trips people up. Restoring a car back to factory configuration is fine. Adding features it never had, including period-correct accessories from a different trim level, technically falls outside the statute. In practice the DMV reviews applications case by case, and the line between restoration and modification is not always bright. If your car has departed from its factory build in any noticeable way, expect closer scrutiny.
Classic motorcycles qualify under the same rules and appear on their own line in the DMV fee schedule.2DEPARTMENT OF MOTOR VEHICLES.

What You Save
The point of antique registration is not the plate itself. It is the property tax.
Connecticut taxes motor vehicles as personal property, and each town applies its local mill rate to the assessed value. For a standard registration the assessment tracks the retail value, so a collector car worth $80,000 can generate a serious annual bill. Antique-registered vehicles are assessed at exactly $500 by law, regardless of market value.4Connecticut General Assembly. Personal Motor Vehicle Property Tax Assessments and Rates In a town with a 30-mill rate, that is $15 a year in car tax instead of potentially thousands. For owners of high-value classics, this alone justifies the registration.
Antique-registered vehicles are also exempt from Connecticut’s emissions testing program, which charges $20 per test for standard vehicles. Older engines that were never designed to meet current thresholds do not have to try.
Registration Fees
Older write-ups still floating around online quote $47 or $52 for antique plates. That number is badly out of date. Current fees for a classic passenger car, SUV, truck, van, bus, or motorhome are:
- Registration fee: $120
- Plate fee: $7
- Administrative fee: $10
- Greenhouse gas fee: $15
- Clean Air Act fee: $15
- Passport to the Parks fee: $24
The total comes to $191. Classic motorcycles pay a lower base registration of $63, a $10 greenhouse gas reduction fee, and the same surcharges, totaling $129.2DEPARTMENT OF MOTOR VEHICLES. DMV Fees The Passport to the Parks charge rose from $15 to $24 on July 1, 2025, reflecting an $8-per-year fee built into the registration period.5CT.gov. Passport to the Parks
The math on that $24 fee ($8 per year for three years) tracks Connecticut’s standard three-year non-commercial cycle. The DMV mails renewal notices before expiration. Let it lapse and you can expect a $25 late fee on a standard renewal.2DEPARTMENT OF MOTOR VEHICLES. DMV Fees
How to Apply
Registration runs through Form H-13B, Connecticut’s combined registration and title application. It asks for the vehicle’s make, model, year, VIN, fuel type, body style, and color.6CT.gov. Connecticut Registration and Title Application H-13B You also need proof of ownership, usually a title, or a bill of sale paired with a VIN verification if the vehicle has no Connecticut title.
VIN verifications can be done at a DMV inspection station, by a licensed dealer, or by law enforcement. Motorcycles built in 1980 or earlier have to be verified at the Wethersfield facility.3DEPARTMENT OF MOTOR VEHICLES. Get a VIN Verification You will also need a valid Connecticut Insurance Identification Card showing at least the state’s minimum liability coverage: $25,000 per person and $50,000 per accident for bodily injury, plus $25,000 for property damage.7Connecticut General Assembly. State Minimum Auto Insurance Requirements
You can file in person at a DMV branch or by mail. If your car’s paperwork is complicated (missing title, out-of-state origin, unclear modification history), a branch visit lets you have the conversation instead of trading letters. Mailed applications that are missing anything sit until you send it in.
How You Can Use the Car
An older version of the statute formally limited antique-plated vehicles to exhibitions, parades, and similar events. That explicit list has been removed. What remains is the eligibility definition itself: the vehicle must be preserved because of historic interest.1Connecticut General Assembly. Connecticut Code Chapter 246 – Motor Vehicles A car putting on 15,000 miles a year running errands is hard to describe that way.
The DMV keeps the authority to review and revoke antique registrations. Use the car in a way that plainly conflicts with preservation and you can lose the plates along with the tax and fee benefits. The safe reading of the statute is what most collectors already do: shows, weekend drives, and occasional pleasure use, not commuting or errands.
Insurance
Antique-plated vehicles still need liability insurance at the state minimums.7Connecticut General Assembly. State Minimum Auto Insurance Requirements Those numbers are low for any car and are especially thin for a valuable classic, because liability only covers what you owe other people. Nothing there pays to fix or replace your car.
Most classic owners add a specialty collector policy for physical damage. The important distinction is agreed value versus actual cash value. An agreed-value policy pays a negotiated figure if the car is totaled, which reflects its true collector worth. An actual-cash-value policy pays replacement cost minus depreciation, and on a 40-year-old car that number can be shockingly low. Stated-value policies sit between the two, but the insurer pays whichever is lower, the stated amount or the actual cash value, which can surprise you at the worst possible time.
Collector policies usually require that you own a separate daily-driver vehicle, keep the classic in an enclosed structure like a garage or storage unit, and stay under an annual mileage cap, often 3,500 to 7,500 miles. Those conditions line up with how antique-plated cars are meant to be used in the first place. Some policies allow seasonal daily use for up to five months at higher premiums.
Plate Display
Connecticut issues a single plate for antique registrations, mounted at the rear. The governing statute requires the plate to be shown “in a conspicuous place at the rear of such motor vehicle at all times while the vehicle is in use or operation upon any public highway.”8Justia. Connecticut Code 14-20 – Number Plates for Antique, Rare or Special Interest Motor Vehicles Tinted frames, inside-the-window mounting, and road grime that renders the plate unreadable can all draw a citation.
Connecticut also allows year-of-manufacture plates, meaning original plates matching the car’s model year. Using them requires DMV approval and the plate has to meet legibility standards. Replica or decorative plates are fine for shows and static display but cannot stand in for the DMV-issued plate on public roads.
Transferring and Replacing Plates
When you sell an antique-plated car, the plates stay with you. You can transfer them to another qualifying vehicle by notifying the DMV and completing the transfer process.9DEPARTMENT OF MOTOR VEHICLES. Transfer Your License Plate From One Car to Another The buyer will need to register the car themselves and, if the car qualifies, apply for their own antique plates. Worth mentioning in a private sale so the buyer isn’t caught out.
Lost, stolen, or damaged plates are replaced through Form E-159 at a DMV office.10Department of Motor Vehicles (Connecticut). Form E-159 – Customized Plates and Records The replacement fee is $5 with a police report documenting theft, or $25 without one.11DEPARTMENT OF MOTOR VEHICLES. Replace Your License Plates A case number alone will not substitute for the actual report. Replacement plates come with a new number.
