State law requires that your driving privilege remain suspended or revoked until MVD receives proof of a functioning interlock in each motor vehicle you operate, even though you may not be the registered owner (see ARS 28-1461). The law requires use of the interlock for at least one year from the date that your driving privilege is reinstated or from the date MVD receives the report of conviction, whichever occurs later. If you have no vehicle, or do not intend to operate a vehicle, your driving privilege will remain suspended or revoked until you are ready to install an interlock and reinstate your driving privilege.
