NJ Certification of Interlock Installation Form – The New Jersey Certification of Interlock Installation is an official document issued by licensed Breath Alcohol Ignition Interlock Device (BAIID) service centers after installing an approved ignition interlock device. This form, provided by the New Jersey Motor Vehicle Commission (MVC), serves as proof that a court-ordered or voluntary ignition interlock device has been properly installed in a vehicle. Drivers in New Jersey who face Driving While Intoxicated (DWI) or related offenses often need this certification to obtain a restricted interlock license or to comply with sentencing requirements under state law.

What Is the Certification of Interlock Installation?
Under New Jersey regulations (N.J.A.C. 13:19-6.11), every licensed BAIID service center must provide the program participant with a certificate of installation on a form supplied by the MVC immediately after completing and delivering the device installation. This document confirms that an approved ignition interlock device has been installed correctly and that the driver has received the required training.
The form is primarily completed by the licensed installer (provider access is password-protected on the MVC site). The driver then uses the completed certificate as official proof when dealing with the MVC or the court.
When Is This Form Required in New Jersey?
New Jersey law (N.J.S.A. 39:4-50.17 and 39:4-50.18) mandates ignition interlock devices for nearly all DWI and breath-test refusal convictions. The Certification of Interlock Installation is typically needed in these situations:
- After a court orders installation of an ignition interlock device.
- When applying for a restricted driver’s license with an interlock notation at an MVC agency.
- For voluntary (pre-conviction) installation, which can reduce certain penalties under current law.
- As part of the documentation submitted to the MVC to start or document the interlock period.
Installation periods vary by offense and blood alcohol concentration (BAC) level. For example, a first offense with BAC between 0.08% and under 0.10% generally requires three months, while higher BAC levels or subsequent offenses require longer periods (often 7–15 months or more).
Required Information on the Form
According to N.J.A.C. 13:19-6.11, the certificate of installation must include at least the following details:
- Service provider’s name, address, and telephone number
- Installer’s signature
- Date of installation
- Name and address of the registered owner of the vehicle
- Name and address of the person required by the court to have the device installed (if different from the owner)
- Make, model, year, vehicle identification number (VIN), and license plate number of the vehicle
- Date of the offense for which the device is being installed
- Name and address of the court that ordered the installation
The service center must also attach the service invoice to the certificate.
How to Obtain the Certification of Interlock Installation?
Only installers licensed by the New Jersey MVC may perform the installation and issue this form. Follow these steps:
- Select an approved manufacturer and confirm that the specific installer is currently licensed by the MVC.
- Schedule an installation appointment (most providers offer same-day or next-day service).
- Bring required documents: photo ID, vehicle registration, and proof of address (such as a recent utility bill). If the vehicle is not registered in your name, the owner must usually be present.
- Complete installation and training. The installer will then provide the completed Certification of Interlock Installation form along with the invoice.
View the official list of approved ignition interlock manufacturers on the New Jersey MVC Interlock Manufacturers page. A full list of licensed installers is also available as a PDF on the same site.
Submitting the Form to the New Jersey MVC
Once you receive the completed certificate:
- Take the Certification of Interlock Installation, the service invoice/work order, and any court documentation (or documentation of pending charges for voluntary installs) to an MVC agency.
- Request a driver’s license with the interlock restriction notation. The MVC will imprint the required notation stating that you may not operate a motor vehicle unless it is equipped with an ignition interlock device.
- For voluntary pre-conviction installations, additional steps may be required after sentencing: obtain a new post-conviction certificate from the provider and return to the MVC so the official interlock period can begin on your record.
Always submit documentation promptly. Under N.J.S.A. 39:4-50.18, the request for the interlock notation must include a copy of the installer’s certification and must generally be submitted no later than seven days after receipt of the required documentation.
Related Forms and Compliance Requirements
In addition to the installation certificate, New Jersey uses other related forms:
- Certification of Voluntary Install – used for pre-conviction installations.
- Certification of Interlock Compliance-Based Removal or Non-Compliance – required at the end of the ordered installation period. The vendor must certify that during the final 30 days there was no more than one failure to take or pass a test at 0.08% BAC or higher (with a timely re-test curing a single failure) and that all maintenance and monitoring requirements were met.
These forms are also available on the official NJ MVC Forms page (provider password may be required).
Devices must meet National Highway Traffic Safety Administration (NHTSA) model specifications, use a 0.05% BAC set point, and be serviced at intervals not exceeding 60 days.

Important Tips for New Jersey Drivers
- Only use MVC-licensed installers. Using an unlicensed provider can invalidate the certification and delay license restoration.
- Keep copies of every certificate, invoice, and service record. You will need them for MVC visits and potential court appearances.
- Service the device on schedule (usually every 30–60 days depending on the provider and court order). Missed calibrations or high BAC readings can extend the required installation period.
- If you no longer own or operate a vehicle, notify the court and MVC immediately and follow their instructions regarding the interlock requirement.
- For the most current rules, always check the official New Jersey Motor Vehicle Commission website and consult the relevant statutes (N.J.S.A. 39:4-50.16 et seq.).
