- Operating under the influence of alcohol or drugs
- Vehicular manslaughter
- Vehicular assault
What to Do
Forms and fees should be submitted to DMV at least two weeks prior to your eligibility date.
- Download and print the Ignition Interlock Device Installation Application (P-246 form). Complete part 1 of the application and sign the Operator Certification section.
- The vehicle listed on the form must have a valid registration. If your name is not listed on the registration as the owner or the lessee, the registered owner must complete part 2.
- Contact one of the Connecticut-approved IID vendors to schedule an appointment to have the IID installed. The installer will complete part 3 of the application.
- Submit the completed P-246 form. If the vehicle is registered outside Connecticut, you must submit a copy of the valid registration certificate. P-246 form may be mailed to the address below or emailed to the email address below.
- Pay the $175.00 restoration fee and the $100.00 IID Administration fee. Fees may be paid by a check or money order made payable to DMV and submitted with your IID application or you can pay the fees online.
Getting Your License Back
You may have other suspension matters, in addition to the IID, which must be resolved in order to be reinstated. After all restoration requirements are met and your suspension time has been served, you will be reinstated with IID requirement.
A final approval letter and restoration notice will be mailed to you. You may operate only a vehicle equipped with an IID for the duration required
After you are restored, you must ensure that you have a current, valid driver license. If you were issued a Connecticut non-driver photo ID card during the suspension, you may exchange the ID
for your previously held Connecticut driver's license.
If you hold an out-of-state driver license you must verify with the issuing state that it is valid before operating a vehicle. If you are now a Connecticut resident, you must transfer your out of state license
Changes to Vehicle or IID Vendor Must Be Reported to DMV
If you install an IID in an additional vehicle, move your IID to a different vehicle, or change IID vendors, you must complete a new Ignition Interlock Device Installation Application (P-246 form
). Check the appropriate box(es) for your situation and send the completed application to Driver Services within 48 hours.
IID Requirement from Another State
If you have moved to Connecticut and you have an IID requirement from your previous home state, your requirements will carry over to Connecticut.
Prior to getting a Connecticut license, you must complete this process with DMV's Driver Services Division:
- Submit the terms of the other jurisdiction's IID restriction.
- Submit a certified copy of your driving history issued by the state that imposed the IID restriction. The history must be less than sixty (60) days old on the date it is submitted
- Download and print the Ignition Interlock Device Installation Application (P-246 form). Complete part 1 of the application and sign the Operator Certification section. The vehicle listed on the form must have a valid registration. If you are not the owner of record for the vehicle, the registered owner must complete and sign part 2.
- If your IID is currently installed by one of the Connecticut approved IID vendors, have the vendor or installer complete part 3. If the IID is installed by a non-approved vendor, contact one of the Connecticut-approved IID Vendors to have a new IID installed. The installer will complete Part three (3) of the application.
- Submit the completed P-246 form. If the vehicle is registered outside Connecticut, submit a copy of the valid registration certificate. P-246 form may be mailed to the address below or emailed to the email address below.
- Pay the $100.00 IID Administration fee. Fees may be paid by a check or money order made payable to DMV and submitted with your IID application or you can pay the fees online.
Your Responsibilities with an IID
- Your DMV record will indicate that an IID must be installed in each vehicle(s) owned or operated by you. Law enforcement officials will have access to this information.
- You must bring each vehicle to the installer every 30 days for calibration. Failure to do so will result in the suspension of your driverís license for failure to comply with the terms of the IID program.
- Anyone convicted of tampering with an IID, requesting someone else to blow into the IID, driving a vehicle without an IID, or who removed the IID without authorization will have their driver's license suspended.
- See additional violations and penalties for failure to comply with the terms of the IID program.
You can call the toll free number(s) below for IID cost, installation, or appointment information.
Participants in the IID program must pay all costs related to the installation and maintenance of the IID directly to the vendor. Costs are determined by the independent vendors and not the DMV.
