Will the interlock lose all memory if the battery is disconnected?

No. The device has a battery back up to protect the data log's memory. However; due to security precautions to detect tampering, if the device detects a change in battery voltage; such as a ‘battery disconnect’, it may register as a tampering event and recall your device to the service center so the technician may conduct a tamper check and this may be reported to the MVD as a tampering violation. If mechanical services must performed on your vehicle, please notify your manufacturer prior to services.

I have more then one vehicle but cannot afford or choose not to put a device in all of them. What do I do?

ARS 28-1461 states that the person shall not operate a motor vehicle unless it is equipped with a certified ignition interlock device. If you cannot install on all your vehicles, it is not permissible for you to drive your other vehicles that are not installed with an interlock device during your requirement.

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.
