Ignition Interlock Program Stakeholders

This site was developed as a resource for stakeholders of the Ignition Interlock Program. It is intended to be a resource guide for Manufacturers, IISPs, and their teams.  These pages, though helpful, are not intended for the customers. Customers please refer to the Ignition Interlock pages.

If there is any information you feel you need to see, that is not on this site, please let us know.

Frequently used Definitions:

“Manufacturer” means a person or an organization that is located in the United States, that is responsible for the design, construction, repair, and actual production of the ignition interlock device and whose device is certified by the Department to offer ignition interlock devices for installation in motor vehicles in this state. The manufacturer is responsible for overseeing any agents or subcontractors, including vendors and distributors, as well as overseeing the manufacturer’s IISP to ensure adherence to all performance standards.

“Ignition Interlock Service Provider” (IISP) means a person who is an authorized representative of a manufacturer and who is under contract with the department to install or oversee the installation of ignition interlock devices by the provider’s authorized agents or subcontractors and to provide services to the public related to ignition interlock devices.  

“Service center” means an established place of business approved by the Department from which an IISP or its agents or subcontractors provide ignition interlock services to persons from one or more counties.

“Technician” means a person who is certified and properly trained by an ignition interlock service provider to install, inspect, repair and remove certified ignition interlock devices.


2019 Inspections

In 2018 we started conducting virtual inspections for our new locations and most non-compliance follow up inspections.  We utilize either Facetime (for Apple devices) or Google Duo (for Android devices) and call the technician directly.  We will call the service center to schedule the inspection and obtain the one time phone number for the inspection. This phone number is not saved, as this number may be directly to the tech, or the individual who has the smart device, and different from the service center.

This new electronic process has enabled us to process initial applications and follow ups inspections in a more efficient manner.  In turn, this has enabled our manufacturers to address pending issues quicker and open service centers faster, helping our customers sooner.  Not to mention the countless safety benefits of less time on the road for the inspectors.

Due to the overwhelmingly positive response we have had regarding the virtual inspections, we are looking to expand to incorporate some of our periodic inspections.  In 2019 we will be randomizing our service centers and some will be getting virtual inspections, while others will be getting an unannounced face to face inspection.
