Car Insurance in Connecticut

What is different about car insurance in Connecticut?

Three things set Connecticut apart from most states. You cannot skip uninsured motorist coverage, which pays your medical bills when the other driver has no insurance or too little. The DMV checks your policy against its records every month. And state law limits the reasons an insurer can drop you.

The basics are familiar. If you cause a crash, your liability coverage pays the other people’s bills, up to your limits. The state minimum is 25/50/25: $25,000 for each injured person, $50,000 for all injuries in one crash, and $25,000 for property damage. Our minimum coverage page shows what those numbers pay in a real crash.

Connecticut is not a no-fault state. It dropped no-fault in 1993, so you do not have to carry personal injury protection. After a crash, the fight is over who was at fault, and the fault is shared out by percentage. You can still collect if you were partly to blame, but not if you were more than half to blame. Sue within two years of the injury.

The state’s own FAQ also mentions a single-limit option. The statute and the DMV list only the three separate amounts, so we use 25/50/25.

Can I turn down uninsured motorist coverage in Connecticut?

No. Every Connecticut liability policy includes uninsured and underinsured motorist coverage (often shortened to UM/UIM). It also covers you when a hit-and-run driver injures you. It pays for injuries, not for car damage.

By default the limits match your liability limits. You can ask for less, but only in writing on a state form, and never below 25/50. Your insurer must also offer you limits at double your liability limits. Roughly 12% of Connecticut drivers were uninsured in 2023 (11.8%, against 15.4% nationally, per Insurance Research Council estimates).

“Underinsured” has a narrow meaning here. The other driver counts as underinsured when their limits are lower than the UM/UIM limit on your policy. If you carry 100/300 and a driver with the 25/50 minimum hurts you, you can claim on your own policy once their coverage is used up.

How much you can collect depends on which version you bought. Here is an example with invented numbers. You carry $100,000 per person and have $140,000 in injury losses. The other driver’s insurer pays its $25,000 limit.

Standard coverage caps your total at your limit, including what the other driver paid. Conversion coverage, an extra-cost option, does not subtract their payment. Ask your agent to price both. Our uninsured motorist guide explains the rest.

How does the DMV know if my insurance lapsed?

Every month, each insurer sends the DMV a list of its active policies. The DMV matches that list to registrations, and police can look up a car in the same system at a stop. If a car shows no coverage, a notice arrives in the mail.

When the gap is longer than 14 days, the usual fix is simple. You show proof of current coverage and pay a $200 civil penalty. Ignore the notice and your registration is suspended. Your license can follow. A court case is a separate and more serious track, covered on our uninsured driving page.

Paperwork causes many of these notices. Here is what the DMV says to do in four common cases.

A worked example: you change insurers on March 1 and the old policy ends on February 28. Your new policy starts on March 1. In April a DMV notice says you lapsed. You were never uninsured, so you mail your new declarations page and keep the mailing receipt. The notice should clear. Do not pay a penalty for a gap that did not happen.

How much does car insurance cost in Connecticut?

The most neutral number is the NAIC’s 2024 state average: $1,564 per insured vehicle a year. That comes from the NAIC’s 2024 Auto Insurance Database supplement, published in September 2026. It is a state figure, an all-driver average that mixes minimum and fuller policies. It is not a quote, and the NAIC warns against comparing states head to head.

That is about 9% above the countrywide average. The breakdown matters more. Connecticut’s liability average is $957, against $813 nationally, while comprehensive runs lower. The state’s premium gap is in liability, not in cover for your own car.

Published estimates depend on who is being priced. These use one clean-record driver each, and none is a quote.

“Fuller” here means 100/300 injury limits with collision and comprehensive. Deductibles are $500 in the first two and $1,000 in the third. All three rely on one rate supplier, so they are not three independent checks.

Connecticut also limits surcharges, the extra charge an insurer adds after a ticket or claim, in several common cases. See our cheap car insurance page for side-by-side figures and the full coverage page for what the extras buy. Drivers over 60 can cut their premium with an approved safe-driving course, says the Insurance Department.

What can my insurer do to my policy?

Connecticut sets firm limits on how an insurer can walk away.

• Cancelling mid-term: once a policy is 60 days old, only for nonpayment, or if the license or registration of you, a household member or a regular driver is revoked. Notice must give the reason. In the first 60 days these limits do not apply.
• Not renewing: 60 days’ notice with the reason. Your renewal bill must arrive at least 30 days ahead.
• Barred reasons: one or two not-at-fault accidents with no moving-violation conviction, credit history alone, or an earlier assigned-risk policy.
• Credit scoring: allowed only under a filed program that cannot count credit inquiries or medical debts. Divorce, serious illness or a long job loss can qualify you for an exception.
• Notice contact: your policy comes with a form to name someone, like an adult child, who also gets cancellation notices.
• Last resort: if no insurer will write you, the state’s assigned-risk plan must offer at least the minimum limits.

Two changes arrive January 1, 2027. Renewal bills that show a higher premium must say you can ask why it rose, and the insurer must answer within 20 business days. And an insurer may not raise your rate or refuse renewal only because you volunteer as a driver for a charity.

What do I do after a crash or a claim dispute?

Start by learning how much the other driver has. An injured person can send the insurer a certified-mail request with the bills, the accident report and a letter from a lawyer or a signed affidavit. The insurer then has 30 days to disclose the limits, including umbrella coverage it wrote.

For fights over repair cost or car value, file a complaint with the Insurance Department first. If it cannot settle the dispute, and nobody argues about fault or coverage, the state’s auto arbitration program may take it. The program’s guide lists a $20 fee for each side and a decision within 15 days. It is an older edition, so confirm the fee with the Department.

Two more rights help: a total-loss value must be at least the average of two approved sources of retail car values, and you may choose any repair shop.

Complaints go to the Connecticut Insurance Department at (860) 297-3900 or (800) 203-3447. DMV notices go to the Insurance Compliance Unit at 860-263-5725. This page is general information, not legal advice.

Which Connecticut guide should I read next?

We list no city pages for Connecticut at this time, so these state pages are your best path.

For background, read no-fault vs at-fault states and how to lower your car insurance. You can also try the state minimum lookup.

What to do next

1. Find your declarations page. Check that your UM/UIM limits are what you meant to buy. Ask the price of double limits and of conversion coverage.
2. Treat 25/50/25 as a floor. It pays other people only. Any injury above $25,000 per person comes from your savings. Get quotes at the minimum, at 50/100/50 and at 100/300/100.
3. Check your lender’s rules. Collision and comprehensive are optional by law, but lenders require them.
4. Audit your driver list. Insurers list every licensed household member with access to the car unless that person has their own car and policy. Ask about a named-driver exclusion first.
5. Keep proof when you switch insurers. Save the new declarations page and the date it started.
6. Re-shop every renewal. The Department recommends shopping yearly. Note that a personal policy generally excludes business use, such as pizza delivery.

Bottom line

If you are buying or renewing, confirm your uninsured motorist limits first, because Connecticut makes them part of every policy. If you got a DMV notice, send proof of continuous coverage rather than paying a penalty you may not owe. If you have a dispute with your insurer, start with the Insurance Department.
