I received an interlock extension order and have requested a hearing. Do I need to keep the interlock on my car while waiting for the hearing for the extension order?

There is no simple answer to this question. Of course, you must keep the interlock installed until the end of the original requirement period. If you are still waiting for your hearing when the original period expires and you keep the device installed, you will be responsible for the additional maintenance expenses. If you remove the interlock and the decision of the Hearing Office is not in your favor, you must have the interlock reinstalled (at your own expense) to begin the extension requirement.

What kind of violations will cause MVD to extend my interlock requirement?

You should contact your interlock manufacturer or authorized service center for questions or concerns regarding violations. However, you may also refer to any training material or brochures provided to you by your interlock provider at the time of installation. You may also refer to the Certified Ignition Interlock tab of this page.
