Ignition Interlock Laws

  • The state of Connecticut defines driving under the influence as operating a vehicle with a BAC of .08% or higher. For drivers under the age of 21, the threshold for the offense is lowered to .02%.
  • Connecticut ignition interlock laws state, drivers whose license has been suspended for a DUI conviction may apply to enter an ignition interlock device program after serving a minimum term of suspension.
  • For most first- and second-time offenders, the minimum term is 45 days.
  • Offenders under 21 may not enter the program until after their twenty-first birthday.
  • Offenders with more than two convictions are not eligible for the ignition interlock program and may face higher fines and permanent license revocation.

License Suspension

Administrative Suspension

If a driver fails or refuses to take a field breathalyzer test upon being stopped for suspicion of DUI, the driver’s license will be automatically suspended by the Department of Motor Vehicles for a period of six months to six years, depending on the driver’s age, BAC, and conviction history.

For a driver under 21, the suspension will last until the driver’s twenty-first birthday.

Judicial Suspension

Upon conviction or the establishment of a plea agreement, offenders are subject to further suspension or license revocation, along with fines and jail time under the Connecticut DUI laws.
