Collector and Classic Car Insurance in Connecticut

By Jon Merwin, Founder and CEO

Connecticut has one of the most active collector car communities in the Northeast, from concours-level cars in Fairfield County garages to muscle cars and vintage pickups at weekend cruise nights across New Haven County. The state also has its own rules: a 20-year threshold for Classic Vehicle plates, a property tax break for qualifying antiques, and a separate legal category for modified antique vehicles. This page covers what is specific to insuring a collector car in Connecticut. For how collector car insurance works in general, read our classic and collector car insurance guide.

Portsmouth Atlantic Insurance is a family-owned independent agency with a Connecticut office. Our collector car carriers include Hagerty, J.C. Taylor, Liberty Mutual, Cincinnati and American Modern, among others, and we’ll confirm eligibility for your vehicle before you rely on a policy.

Connecticut Classic Vehicle plates and your insurance

Connecticut issues Classic Vehicle plates (formerly Early American plates) for collectible vehicles at least 20 years old. Under state law, an antique, rare or special interest motor vehicle is one 20 years old or older, preserved because of historic interest, and not altered from the original manufacturer’s specifications (CGS 14-1). Owners can also apply to display a Connecticut plate from the car’s year of manufacture (CGS 14-20).

Here is the part that surprises many Connecticut owners: state law doesn’t restrict how a classic-plated car is driven. Your collector insurance policy almost certainly does. Collector policies are written for hobby use, including shows, club events, parades, tours and occasional pleasure drives. If a classic-plated car is your daily commuter, it probably belongs on a standard auto policy instead, and we can help you decide.

Because Connecticut’s plate threshold is 20 years, a lot of ordinary older cars carry classic plates. A plate doesn’t make a car eligible for collector insurance. Insurers look at condition, value, use, storage and drivers. See antique vs. classic car insurance for how state and insurer definitions differ.

Modified antique vehicles in Connecticut

Connecticut also recognizes a “modified antique motor vehicle”: a vehicle 20 years old or older that has been modified for safe road use, including changes to the drive train, suspension, braking system, and safety or comfort equipment (CGS 14-1). Resto-mods with disc brakes, modern fuel injection or upgraded suspension often fall here. Insurers usually place modified cars in a separate program with more documentation, so read our guide to modified car insurance for hot rods, street rods and kit cars.

Connecticut insurance requirements still apply

Unlike New Hampshire, Connecticut requires every registered vehicle to carry minimum liability and uninsured/underinsured motorist coverage, and classic-plated cars are no exception. Our guide to Connecticut car insurance requirements covers the minimums. If you also own a motorhome or travel trailer, see RV insurance in Connecticut. Many collectors carry higher limits that match their daily cars, so an umbrella policy can sit on top without a gap.

The Connecticut antique vehicle property tax rule

Connecticut towns tax motor vehicles as personal property. For a qualifying antique, rare or special interest vehicle, state law caps the assessed value (CGS 12-71(b)). Cars registered with Classic Vehicle plates don’t need to provide extra documentation to the assessor; owners of other qualifying cars may need to apply and show the car meets the definition.

That tax assessment has nothing to do with your insurance value. Your collector policy should carry an agreed value based on what the car would actually cost to replace, supported by photos, receipts and appraisals. Don’t let a low tax assessment anchor the number you insure the car for.

Storing a collector car on the Connecticut shoreline

Many Connecticut collectors live near Long Island Sound, where nor’easters and tropical storms can push water into low-lying garages. Storm surge and street flooding can total a car that never left the garage. To protect a collector car on the shoreline:

• Keep comprehensive coverage in place all year. On an auto policy, comprehensive (other-than-collision) coverage is what usually responds to flood damage to the car.
• Know that home flood policies generally don’t cover cars. A flood policy on your home covers the building and contents, not your vehicles.
• Have a plan. Know where you’d move the car before a forecast storm surge, and whether a trailer or second location is available.
• Store it as the policy requires. A locked, fully enclosed garage is the usual condition.

If you own a high-value home on the shoreline, our pages on high-value home insurance in Connecticut and luxury home insurance in Greenwich, Darien and Westport cover the building side.

Larger collections in Fairfield County

Some Connecticut collectors keep several significant cars, a climate-controlled garage and a home or two to match. For a larger collection, ask about insuring every car on one policy with each car at its own agreed value, coverage for newly acquired cars, and how the insurer handles cars transported to concours events or out-of-state shows. Our high net worth insurance team can coordinate the collection with your homes, daily cars and umbrella.

Frequently asked questions

Do Connecticut Classic Vehicle plates limit how I can drive my car?

Connecticut law doesn’t put a use restriction on vehicles with Classic Vehicle plates the way some states do. Your collector insurance policy is a different matter. Collector policies are written for hobby use, such as shows, club events, parades and occasional pleasure drives, so commuting or errands in a collector-insured car can be a problem. Tell us how you actually drive the car.

Does Connecticut require insurance on a classic car?

Yes. A registered vehicle in Connecticut must carry at least the state’s minimum liability and uninsured/underinsured motorist coverage, and that applies to classic-plated cars too. A collector policy provides that required coverage and adds agreed value protection for the car itself.

What is a modified antique motor vehicle in Connecticut?

Connecticut law defines it as a vehicle 20 years old or older that has been modified for safe road use, such as changes to the drive train, suspension, brakes, or safety or comfort equipment. Insurers may still treat a modified car differently from an original one, so tell us about every modification and we’ll confirm eligibility for your vehicle.

Will my classic car get a lower property tax bill in Connecticut?

Possibly. Connecticut caps the property tax assessment of a qualifying antique, rare or special interest vehicle: one at least 20 years old, preserved for historic interest and not altered from the manufacturer’s specifications (CGS 12-71(b)). Cars with Classic Vehicle plates don’t need to provide extra documentation; others may need to apply to the town assessor.

How should I protect a collector car from coastal storms in Connecticut?

Keep comprehensive coverage in place all year, store the car in a locked, enclosed garage, and have a plan to move it to higher ground before a forecast storm surge. Comprehensive coverage on an auto policy is what usually responds to flood damage to the car itself; your home flood policy generally doesn’t cover vehicles.

Can you insure my collector car if I live in Connecticut?

Yes. We have a Connecticut office, and we work with collectors across Fairfield County, New Haven County and the rest of the state. Call (603) 431-4020 and we’ll confirm eligibility for your vehicle.
