A Connecticut DUI is really two cases at once — the criminal charge in court, and a license suspension at the DMV that moves on its own faster deadline. Both can be defended. But the clock started the night of the arrest.
A Connecticut OUI arrest can trigger a separate DMV administrative suspension. DMV states that, in most cases, the administrative suspension is 45 days and begins 30 days after arrest, followed by an ignition-interlock requirement whose duration depends on the testing/refusal history and age. A court conviction also carries separate license and IID consequences.
Under the current OUI statute, a first conviction carries a $500–$1,000 fine and up to six months of incarceration. The statute provides either 48 consecutive hours that may not be suspended or reduced, or a fully suspended jail sentence with probation conditioned on 100 hours of community service.
A conviction can affect driving privileges and may create employment, insurance, licensing, immigration, or other collateral consequences depending on the person’s circumstances. No particular outcome can be promised.
Current-law note: penalty and license information reviewed August 20, 2026 against General Statutes §§ 14-227a and 14-227b and current Connecticut DMV guidance. Special rules can apply based on age, prior history, testing/refusal facts, injury, a child passenger, or another charged offense.
Can a DUI simply be “knocked down”? Connecticut law places a special condition on DUI dispositions. Under C.G.S. § 14-227a(f), a charge under § 14-227a(a) may not be reduced, nolled, or dismissed unless the prosecuting authority states the reasons for that disposition in open court. That does not make a favorable disposition impossible, but it does mean the record must reflect why the charge was reduced, nolled, or dismissed.
Every element, beyond a reasonable doubt. A DUI has fewer than people think — and each one is a place the case can fail.
That you were operating the vehicle. Parked-car cases, keys-in-console cases, and accident cases with no witness to driving all put this element in play.
Operation must occur on a public highway or in areas the statute reaches — private property cases raise real issues.
Impairment, or an elevated BAC established by a properly administered, properly calibrated test, run inside the required time window by certified operators. Every one of those qualifiers is a defense opportunity.
When a case begins with a traffic stop, the State must be able to justify the seizure under the applicable constitutional standard. Some OUI investigations begin in other ways, including crashes, checkpoints, consensual encounters, or reports of driving. If a stop or detention was unlawful, suppression may become an important issue.
Field sobriety testing, breath testing, blood or urine evidence, instrument records, officer training, observation requirements, timing, and statutory admissibility requirements can all matter. We compare the report to the underlying video and records rather than assuming the testing was performed correctly.
The client’s history, work, family, treatment, driving needs, and other circumstances can matter to strategy. Program eligibility is statutory and fact-specific; a “first arrest” does not by itself establish eligibility.
Connecticut law provides a pretrial impaired-driving intervention program for certain eligible defendants. Successful completion can provide a statutory path to dismissal, but eligibility is not determined simply by calling a case a “first offense,” and the program does not eliminate the need to address the separate DMV process. The program should be evaluated against the evidence, defenses, and consequences in the individual case.
When we first evaluate a Connecticut DUI / OUI arrest, we want to know four things quickly: Was anyone injured? Was there an accident? Are there prior DUI arrests or convictions? What was the basis for the stop? Those answers tell us where the defense analysis needs to begin.
An accident or injury can change the stakes. Prior history can change the available options and sentencing exposure. And the reason for the stop can determine whether evidence gathered afterward is even available to the State.
We regularly examine whether police had a lawful basis to stop or detain the vehicle. If the stop was unlawful and the resulting evidence is subject to suppression, the field tests, statements, chemical testing and later observations can all be affected.
We also ask what the officer actually saw before the stop. Was there weaving, speeding, a traffic violation, an accident or some other observed driving problem? The absence of poor driving does not automatically defeat the charge, but it matters when the State is trying to prove impairment from the entire sequence of events.
Body-camera footage is key evidence when field sobriety testing is disputed. We compare the officer’s written account with what the video actually shows: the instructions, demonstration, surface, lighting, footwear, physical limitations, balance, coordination and the client’s actual performance.
When the field tests matter, we may also obtain the officer’s training records and work with an appropriate expert to evaluate whether the tests were administered and interpreted properly. A police report saying someone “failed” a test is a conclusion. We want to see the underlying evidence.
We look at when the test occurred, how close the reported BAC was to the legal limit, and whether the available evidence suggests the BAC was rising or falling. Timing can matter because the test occurs after the driving event the State is trying to prove.
The closer the reported result is to the legal limit, the more important it can be to understand the timing, instrument records, observation period and surrounding evidence instead of treating one number as the entire case.
The usual observations associated with alcohol intoxication do not automatically translate to alleged drug impairment. We want to know what substance the State claims caused impairment, what signs the officer relied on, whether a drug-recognition evaluation was performed, what toxicology exists, and whether those facts actually establish impairment at the relevant time.
Presence of a substance and impairment from that substance are not always the same question.
One of the most important weaknesses we see in some DUI cases has nothing to do with field tests or BAC: Can the State prove that the client operated the vehicle?
That issue can arise where police never observed the driving. We look at who was in the vehicle, where it was located, whether it was running, who had the keys, what witnesses saw, what the client said, and whether video or other evidence connects the client to operation.
As automated and self-driving technology becomes more common, operation will remain a fact-specific legal issue. We analyze the technology and facts against the law rather than assuming the answer.
For a first arrest, a program that can lead to dismissal may be extremely valuable. But our first question is still whether the State can prove the case.
If there is a substantial legal or factual defense, we want to understand it before a client uses an important program opportunity simply because the program looks like the easy path. Once we understand the evidence, we review the available options, the risks, and what matters most to the client. Then we make the decision together.
Subsequent-offense cases can involve mandatory sentencing provisions and fewer diversionary options. Even then, the case is not reduced to a sentencing chart. The strength of the proof, the client’s history and circumstances, and the State’s negotiating position still matter.
Sometimes prosecutors begin above a statutory minimum. Advocacy can matter in whether that position changes. The defense therefore has to evaluate both the proof and the person.
That is our immediate advice. Before making decisions, understand what happened, what evidence exists, what deadlines apply, and what options are actually available. An arrest starts the case; it does not decide it.
Connecticut’s DUI instruction separates operation from impairment or elevated BAC. That matters when the evidence does not clearly establish who was driving or whether the accused intentionally used the vehicle controls in a way that would set the vehicle in motion.
Under the standard instruction, the State may proceed on an impairment theory, an elevated-BAC theory, or both when charged. Driving behavior is relevant to impairment, but it is not conclusive by itself. Chemical-test evidence also has its own evidentiary role and timing questions.
When refusal evidence is admitted, jurors may be permitted to draw a reasonable inference from the refusal. That makes the circumstances of the request, the client’s response, and the surrounding recordings important evidence to review.
