Drivers convicted of an Arizona DUI can drive only in a vehicle with an ignition interlock device installed. A Breath Alcohol Ignition Interlock Device (BAIID) is a breathalyzer with computer logic and memory that interconnects with the ignition and other vehicle control systems. The interlock measures the blood alcohol concentration (BAC) of the intended driver, and prevents the motor vehicle from being started if BAC exceeds the limit of .03%
The interlock will ask for random breath tests while vehicle is running. If you acquire three startup test violations, one rolling retest failure, or the device detects tampering, you must immediately have the interlock device serviced, or it will lock out the car from further operation. Any violation can cause an extension of your interlock term, or result in your license denied/revocation status to be reinstated.
