Car Insurance After a DUI in Connecticut

Do you need an SR-22 after a DUI in Connecticut?

Usually not. An SR-22 is a form your insurer files with the state to prove you carry coverage. Many states require one after a drunk-driving conviction. Connecticut stopped doing that automatically in 2004.

Today the DMV can still ask for proof of insurance if it decides your record on file calls for it. If that happens, you get a notice that says what to file. Your insurer then sends the certificate, and the law lets the insurer charge up to $10 for it. After a year you can ask the DMV to drop the requirement.

You will still read the opposite online. Two comparison sites tell Connecticut drivers an SR-22 is required, and neither backs that claim with a Connecticut law or DMV page. If a quote adds one, ask which DMV notice requires it. See our Connecticut SR-22 page and the SR-22 guide.

What about an FR-44, the higher-limit version some states use? None of the DMV pages we read mention one, though that is silence, not a statement. See our FR-44 guide.

What happens to your license after a DUI arrest in Connecticut?

One arrest starts two separate clocks. The DMV suspends you on the police report if you fail or refuse the breath or blood test. The court case runs on its own track. A court outcome does not by itself cancel the DMV suspension.

Here is an example with invented dates. You are 30, you are arrested on March 1, and you blow a .09.

• Days later: a DMV notice arrives. You have 7 days to ask for a hearing.
• About March 31: the suspension starts, usually 30 days after the arrest.
• About May 15: after 45 days you can get your license back, once an interlock is installed and the fees are paid.
• About November 15: the interlock can come off if you were not convicted. After a conviction it stays a full year from restoration.

An ignition interlock is a breath-test device wired into the car. You blow before it will start. Three things surprise people:

• The clock starts the day the license is restored, not the day the device is installed.
• It goes on every vehicle you own or drive, and the DMV sets no price. Installers charge what they charge. If you receive SNAP or LIHEAP benefits, a letter from the Department of Social Services can earn a discount.
• The state’s work, school and medical permit does not help. Anyone suspended for an alcohol offense is barred from it, so plan on 45 days with no driving.

Plan on $275 in DMV fees to get back on the road. Pay online at least 10 days before your eligibility date.

Will your insurance company cancel you or raise your price?

It cannot cancel you on a whim, but it can raise the price or let the policy end. Connecticut limits what a regular insurer can do.

• Cancelling mid-term. On a policy in force 60 days or more, it needs one of two reasons: you stopped paying, or a license or registration was revoked for you or a household driver. A conviction on its own is not on that list. Connecticut’s DMV calls the 45-day penalty a suspension, not a revocation. If an insurer cancels, ask which reason it is using.
• Not renewing. The insurer can decline to renew on 60 days’ written notice with the reason in writing. The renewal bill must reach you at least 30 days before the renewal date. That is your window to shop.
• Newer policies. The cancellation limits do not apply in the first 60 days, so answer the DUI question on any application truthfully.
• Banned reasons. An insurer cannot refuse you only because another company turned you down or because you used the assigned-risk plan before.

From January 1, 2027, a bill announcing a higher premium must say you can ask why. The insurer then has 20 business days to answer.

How much more does car insurance cost after a DUI in Connecticut?

A lot more, but the published estimates disagree because they describe different drivers. We do not average them.

• Insurance.com (September 2026): a 40-year-old with full coverage pays $8,432 a year after one DUI, against $2,742 with a clean record.
• MoneyGeek (February 2026): a 40-year-old man with liability-only coverage pays $2,066 a year, about $912 or 79 percent more.
• NerdWallet (October 2026): a 35-year-old with state-minimum limits and a DUI six months old sees monthly rates of $62 to $271 across five insurers.

Notice what moves the number. Full coverage costs far more than liability-only, and the insurer you pick can change your price several times over. MoneyGeek’s “minimum” is higher than Connecticut’s legal limits (see Connecticut minimum limits). These are estimates, not quotes. Your own price depends on your record, car, address and insurer.

How long does a DUI stay on your record in Connecticut?

It depends which record you mean. The state and your insurer count differently.

• DMV driving history: most violations stay on it for 3 years, and some serious ones for up to 10. The DMV page does not say which group a DUI falls into. Pull your own history to see what insurers see.
• Repeat offenses: a second conviction within 10 years brings a longer interlock and bigger fines, and a third can mean permanent loss of your license.
• Your insurer: no law sets how long it can charge extra. Each company files its own rating plan. Guides say 3 to 5 years, and one Connecticut page also says about 10. Ask each company how many years it counts.

First-time defendants can ask the court for a pretrial program. It lasts about a year, includes an alcohol education course or treatment, and costs several hundred dollars. The charge is dismissed if the court finds you completed it. The DMV suspension still happens, and the DMV keeps a record of the program on your driving history for 10 years. The court decides who qualifies, so ask a Connecticut defense attorney.

What if no regular insurer will cover you?

Connecticut runs an assigned-risk plan for drivers who cannot buy coverage the ordinary way. Every auto insurer in the state takes part. Industry guides say you apply through a licensed agent or broker.

The plan sells the legal minimum, plus fire, theft and collision coverage. Liability up to 250/500/100 is available. Expect a $35 agent fee and a down payment of at least 25 percent. A company that drops you for a reason other than nonpayment must tell you that you may qualify.

Treat it as a last stop. Ask a few regular insurers first. Our high-risk insurance guide explains how non-standard companies work.

What happens if you let your insurance lapse while suspended?

Do not drop coverage because you cannot drive for a month and a half. Connecticut expects every registered car to stay insured the whole time. When a lapse runs past 14 days, the DMV can send a suspension notice. You can resolve it with a $200 civil penalty. If you ignore it, your registration is suspended, and the DMV can later suspend your license too.

If you truly will not insure a car, the DMV’s route is to cancel the registration. Do not simply stop paying. See driving uninsured in Connecticut.

Switching insurers can also trigger a false notice. Fix it with your new declarations page or a letter proving continuous coverage.

What to do next

1. Read the DMV notice the day it arrives and write down the hearing deadline. You get 7 days to ask.
2. Keep every registered car insured, and pay each premium on time.
3. Choose an approved interlock installer from the DMV’s list, and pay the $175 and $100 fees online ahead of your eligibility date.
4. Do not buy an SR-22 unless a DMV notice asks for one. If it does, ask your insurer to file it.
5. Compare quotes when the renewal notice arrives, using identical limits at each company. Ask each how many years it counts a DUI.
6. Request your driving history so you know what insurers will see.
7. Re-quote at every renewal. A surcharge can shrink or end as the conviction ages, depending on the insurer’s plan.

Common mistakes

• Missing the 7-day window to ask for a hearing.
• Skipping a calibration visit at the installer. Each violation adds 30 days.
• Letting someone else blow into the device.
• Hiding the DUI on a new application.
• Comparing quotes with different limits.

Bottom line

If a DMV letter demands proof of insurance, have your insurer file it. If none arrives, skip the SR-22 and put your effort into three things: no gap in coverage, the interlock on schedule, and fresh quotes at every renewal.
