Aggravated DUI (BAC ≥ 0.15%): Higher BAC levels trigger enhanced penalties in Connecticut. If your BAC was significantly above the legal limit, you may face mandatory minimums, additional fines, or elevated charges. An experienced Connecticut DUI attorney can evaluate the specific circumstances of your case.
What Happens to Your License
Connecticut operates a two-track system — your license faces consequences from both the court and the DMV independently. You must act fast on both fronts.
- 7-Day Rule: You have just 7 days from your arrest to request an administrative hearing to contest your license revocation. Miss this window and your license is automatically revoked.
- 1st Offense Suspension: 45 days A restricted or hardship license for employment purposes may be available.
- Refusal Consequences: Refusing a chemical test triggers an automatic license revocation of 45 days under Connecticut's implied consent law — separate from any criminal penalties.
Connecticut DUI Defense Strategies
Even if you failed a breath test, that doesn't mean your case is lost. Experienced Connecticut DUI attorneys challenge charges on multiple grounds:
Special Connecticut DUI Circumstances
Under 21
Connecticut applies a strict BAC threshold of just 0.02% for drivers under 21. The penalties escalate quickly for repeat violations and can result in license suspension, fines, and required alcohol education programs. A DUI on a young driver's record can affect college applications, employment, and insurance for years.
Commercial Drivers
CDL holders in Connecticut are held to a stricter 0.04% BAC standard while operating a commercial vehicle. A DUI conviction can result in a 1-year CDL disqualification for a first offense — and a lifetime ban for a second offense. Even an off-duty DUI in your personal vehicle can threaten your commercial license and livelihood.
Drug DUI
Connecticut law prohibits driving under the influence of any drug — including prescription medications and marijuana — not just alcohol. You do not need to be above a BAC limit for drug dui charges; impairment alone is sufficient. The same criminal penalties apply, and drug dui cases often involve more complex evidence that an experienced attorney can challenge.
