How Long Does a DUI Stay on Your Record in Connecticut?

A DUI conviction stays on your Connecticut driving record for at least 10 years, and it stays on your criminal record indefinitely unless you take steps to erase it. Those are two different records with two different timelines, and the answer to how long a DUI stays on your record in Connecticut depends on which one you mean. The driving record affects your license status and insurance rates; the criminal record is what employers, landlords, and licensing boards see on background checks.

The 10-Year Rule on Your Driving Record

The Connecticut DMV retains a DUI conviction on your driving history for at least 10 years.¹ Most traffic violations drop off after three years, but DUI is treated as a serious violation with a longer retention period. Anyone who pulls your driving record during that decade — insurers, employers who require driving, licensing agencies — will see it.

Points assessed against your license run on a separate, shorter clock. Points stay on your record for 24 months from the date of assessment.² The underlying DUI conviction remains visible long after the points expire.

Commercial drivers face a far longer retention period. Connecticut keeps DUI records on a CDL holder’s driving history for 55 years.³ For practical purposes, that’s a lifetime record.

Your Criminal Record Has No Automatic Expiration

Unlike the driving record, a DUI on your criminal record has no built-in end date. It stays there permanently unless it’s cleared through Connecticut’s Clean Slate Act or a pardon from the Board of Pardons and Paroles. The criminal record is the one that matters most for background checks — it’s what employers, landlords, and licensing boards search.

A standard background check will surface the conviction regardless of how long ago it happened. When a charge is dismissed or dropped, separate automatic erasure rules apply, but a completed conviction requires one of the routes below.

Automatic Erasure Under the Clean Slate Act

Connecticut’s Clean Slate law changed the picture for DUI records in a way many people don’t realize. DUI convictions under C.G.S. § 14-227a are specifically listed as eligible for automatic erasure, with a 10-year waiting period measured from your most recent conviction.⁴ There’s no application to file. Once the waiting period passes, the erasure happens automatically.

One critical exception. If you were convicted of a DUI and then convicted of another DUI within the following 10 years, neither conviction qualifies for automatic erasure under Clean Slate.⁴ The law is built for people with a single DUI who stayed out of trouble afterward. Repeat offenders inside that lookback window have to pursue a pardon instead.

Pardons for People Who Don’t Qualify

For anyone shut out of Clean Slate — including repeat DUI offenders — the main route to clearing a criminal record is an absolute pardon from the Connecticut Board of Pardons and Paroles. An absolute pardon completely erases the conviction from your official Connecticut criminal record.⁵ Once granted, you can legally state that you have no criminal record.

The waiting period depends on the severity of the offense. You can apply three years after the date of disposition for a misdemeanor DUI, or five years after the date of disposition for a felony DUI.⁶ You cannot be on probation or parole when you apply, cannot have pending charges in any jurisdiction, and cannot have a nolle within the previous 13 months.⁵

You must disclose every conviction on the application, including out-of-state and federal ones. If the Board later discovers an undisclosed conviction, it can revoke the pardon.⁷ A pardon is not a finding of innocence. It erases the record without saying the court was wrong.

Avoiding a Conviction in the First Place

First-time DUI offenders in Connecticut may be eligible for the Pretrial Impaired Driver Intervention Program, which offers a way to avoid a conviction entirely. Successfully completing the program’s requirements results in dismissal of the DUI charge and destruction of the associated records. There’s no conviction to erase later because one never happened.

The risk is real. Failing to meet the requirements can lead the court to revoke your participation, reopen the case, and proceed with prosecution. CDL holders have been ineligible for this diversion program since 2014.⁸

When a Charge Is Dismissed, Nolled, or Ends in Acquittal

If a DUI charge doesn’t produce a conviction, the record follows a different path. Police and court records tied to the charge are subject to automatic erasure.⁹ The timing depends on how the case ended:

After a dismissal or acquittal, records are erased once the time to file an appeal expires, or after a final appeal upholding the dismissal or not-guilty finding.⁹
After a nolle, records are erased once at least 13 months have passed since the nolle was entered.⁹

The arrest may appear on your record during the interim, but once erased, the records are treated as though the arrest never happened.

Why 10 Years Matters Beyond the Record Itself

Connecticut uses a 10-year lookback period to decide whether a new DUI is charged as a first, second, or third offense.¹⁰ That’s part of why the DMV retains DUI records for 10 years — it’s the window in which a prior conviction can trigger enhanced penalties for a new one. The mandatory minimum jail time jumps from 48 hours on a first offense to 120 days on a second inside that window.¹¹ If your prior conviction is more than 10 years old, a new DUI would generally be treated as a first offense for sentencing purposes.

What the Record Costs You While It’s There

The consequences of having a DUI on your record fall into three main buckets.

Driving privileges and insurance. A DUI conviction triggers a 45-day license suspension and a mandatory ignition interlock device once your license is reinstated.¹¹ The interlock stays on for one year after a first offense and three years after a second.¹² Connecticut may also require an SR-22 certificate proving you carry minimum liability coverage, typically for three years and up to five for repeat offenses; a coverage lapse resets the clock. Nationally, a DUI raises annual auto insurance premiums by roughly 65% on average, and that increase persists for as long as the conviction appears on your driving record.

Background checks and employment. The federal Fair Credit Reporting Act generally bars consumer reporting agencies from reporting arrests more than seven years old, but that restriction doesn’t apply to positions paying $75,000 or more.¹³ Convictions, as opposed to arrests, have no federal time limit on reporting at any salary level. A DUI conviction can show up on employment background checks indefinitely unless erased through Clean Slate or a pardon. Federal agencies don’t automatically disqualify applicants with a DUI; they weigh how long ago the offense occurred, its seriousness, and evidence of rehabilitation during a suitability determination after a conditional offer.¹⁴ Professional licensing boards in fields like nursing, law, and education often require disclosure of DUI convictions even after erasure or a pardon; some specifically ask about expunged or sealed convictions, so check with your board before assuming a pardon ends your disclosure obligations.

Travel to Canada. A Connecticut DUI can keep you out of Canada. Under Canada’s Immigration and Refugee Protection Act, a foreign national convicted of an offense that would be a crime in Canada can be found inadmissible.¹⁵ Since December 2018, Canada has classified impaired driving as a serious crime, and Canadian border agents have access to FBI criminal databases. Even a single misdemeanor DUI can lead to denial of entry. A Temporary Resident Permit allows entry for a specific period and purpose and can be valid for up to three years. Criminal Rehabilitation is a permanent solution, but requires waiting at least five years after completing your entire sentence, including fines and probation. Erasing the conviction through a pardon or Clean Slate may resolve the issue as well, since Canadian agents would no longer see the offense in U.S. databases, though there’s no guarantee.

CDL Holders Are on a Different Track

Commercial drivers face longer consequences at every step. Connecticut retains DUI records on CDL holders’ driving histories for 55 years, and CDL holders are not eligible for the Pretrial Impaired Driver Intervention Program that lets other first-time offenders avoid a conviction.⁸ Federal regulations add a one-year disqualification from operating a commercial motor vehicle after a first DUI, three years if hazardous materials were being transported, and lifetime disqualification after a second DUI.¹⁶ For a career built on a CDL, a single DUI can be the end of it.
