How much does it cost?

Cost will vary by the manufacturer and possibly by the service center. In accordance with ARS 28-1462 and A.A.C. R17-5-614, the service provider will collect $20 for each installed or transferred device. All other fees are established by the Manufacturer and service centers. The MVD does not regulate or monitor any fee above the $20 install fee. See Interlock Installation and Monitoring for a complete listing, and choose the one that best fits your needs.

Do you monitor the interlock?

Yes. The interlock manufacturer is required to send reports of your interlock usage electronically to MVD. All violations are reported in real time on a daily basis. If those reports indicate a failure to comply with interlock requirements, tampering, circumvention or certain other violations, you will receive notification from MVD extending your original interlock requirement for an additional six to 12 months.
