What Are the Penalties for a First-Offense DUI in Connecticut?

 Posted on January 20, 2026 in Driving Under the Influence

As of 2026, a first-offense DUI in Connecticut can result in license suspension, fines, mandatory alcohol education, and possible jail time. This is true even if no crash occurred. Many people are surprised to learn that a first DUI in Connecticut still comes with serious penalties, even if they have never been in trouble before.

DUI charges are common nationwide. In 2025, law enforcement agencies reported more than 800,000 DUI arrests across the United States in the prior year, showing how frequently drivers face these charges.

If you were arrested in Fairfield County, understanding the penalties and timelines tied to a first DUI is critical. A Stamford, CT DUI defense lawyer can help you understand what happens next and how to protect yourself early in the process.

What Criminal Penalties Apply to a First-Offense DUI?

Connecticut’s DUI law is found in Connecticut General Statutes § 14-227a. A person may be charged if they operate a motor vehicle while impaired by alcohol, drugs, or both. Even for a first offense, Connecticut law sets minimum penalties that courts must follow. Depending on the facts, penalties may include jail time, fines, and court-ordered conditions.

Common criminal penalties for a first-time DUI conviction include:

• Possible jail time, including a mandatory minimum in some cases, or community service instead of jail

• Fines set by statute

• Court-ordered requirements such as alcohol education or treatment

The exact outcome depends on factors like test results, police observations, and whether an alternative program is available.

Will I Lose My License After a First DUI in Connecticut?

Unfortunately, most people lose their license for a DUI, whether it’s the first offense or not. Connecticut has a separate Department of Motor Vehicles suspension process. This DMV action can happen before the criminal case is even resolved.

A first DUI often leads to a license suspension followed by a requirement to use an ignition interlock device. This is a breath-based system that prevents a vehicle from starting if alcohol is detected.

Does Blood Alcohol Level Affect First-Offense DUI Penalties?

In Connecticut, a driver’s blood alcohol concentration can directly affect the penalties in a first-offense DUI case. While 0.08 is the legal limit for most adult drivers, higher test results often lead to more serious consequences.

When a blood alcohol level is elevated, prosecutors may push for stricter conditions, including longer license restrictions, more intensive alcohol education, or treatment requirements. Higher readings can also influence whether a judge is willing to approve diversionary programs. Even though the charge is still considered a first offense, the facts of the case matter.

In Stamford and throughout Fairfield County, test results are often one of the first things prosecutors focus on when evaluating how a DUI case should proceed.

What Happens if I Refuse a Breath or Blood Test During a DUI Stop?

Refusing a chemical test in Connecticut carries its own set of consequences, even for a first offense. Under Connecticut’s implied consent laws, under § 14-227b, drivers are expected to submit to testing when lawfully arrested for DUI.

A test refusal can trigger an automatic license suspension through the DMV, separate from the criminal case. These suspensions are often longer than those for drivers who submit to testing. Refusal can also limit certain defense options later in the case and may be used as evidence in court.

Because the DMV process moves quickly, drivers who refused testing often have only a short window to request a hearing. Missing that window can result in a suspension taking effect automatically.

Can a First-Offense DUI Be Dismissed Through a Program?

Some first-time offenders may qualify for Connecticut’s Alcohol Education Program. If granted and completed, the DUI charge may be dismissed.

Eligibility depends on the details of the case, including prior history, blood alcohol level, and whether the arrest involved injuries or other serious factors. Admission is not automatic and must be approved by the court.
