Connecticut Ignition Interlock Laws

For first-time offenders and repeat DUI offenders, your license will be confiscated immediately per Connecticut’s Administrative License Revocation (ALR) if:

  • Your blood alcohol concentration (BAC) level was .08 or higher
  • You refused a breath test

Courts in Connecticut require offenders to install and maintain an Ignition Interlock Device (IID) on their vehicles. You’re required to pay for all costs associated with the IID, from installation, monthly lease payments, and service fees to removal.
