What will happen if I don’t live in Arizona and decide not to install an interlock ignition device as ordered by the Court?

Will the NDR be notified? Yes.

This will result in action being taken by your home state. All 50 states have services that can install an ignition interlock device in your vehicle. If you do not comply, this will result in a motor vehicle department action. This action may include, but is not limited to, license suspension, fines, attendance at defensive driving or traffic survival school, extensions of the ignition interlock device on your vehicle and the requirement that you have complied with all court orders.
If you fail to comply with the court order to install an ignition interlock device in your vehicle, Arizona will suspend your driving privileges.

How Quickly Will My Home State Motor Vehicle Department Take Action?

Answer: Maybe never.

How it works:

The information in the NDR database is not automatically provided to motor vehicle departments. The database must be accessed by your home state.
The suspension in another state will only be discovered in the NDR when some entity accesses that database to obtain information. For example, if you have any type of interaction with a motor vehicles department, particularly a driver license application, they will check with the NDR before they issue you a license.
A search of the NDR can be initiated not only when you are applying for a driver license, but also when you are changing your address or insurance companies, stopped by an officer who runs your license, given a traffic citation or have any interaction with your motor vehicle department.

For example, suppose you are driving on a California driver license but were convicted of a DUI in Arizona. You still maintain your California driver license. The Arizona court orders you to install an ignition interlock device on your vehicle for one year. If you fail to install the ignition interlock device, Arizona notifies the NDR that your privileges to drive in Arizona have been suspended.
California may or may not become aware of the Arizona suspension and take action. This will depend on your interaction with the California motor vehicles department. Therefore, your California license may continue to be valid, but understand you are taking the chance that if you are stopped by an officer in California and he runs a national driver check, your license will show as suspended in Arizona. The officer could have your car towed, give you a ticket for driving on a suspended, or revoked license and, depending on your driving record, you could end up serving jail time.
