Ignition Interlock Devices (IIDs)


Arizona DUI Laws require Ignition Interlock Devices for all DUI Offenders

According to Arizona DUI Laws, all DUI convictions now require installation of an ignition interlock device for at least one year after regaining their driving privileges. Governor Janet Napolitano signed SB1029 into Arizona DUI Law on May 18th requiring DUI offenders to install the ignition interlock device in their vehicles. Before the law was passed, ignition interlocks were only required in vehicles of extreme DUI cases or by repeat DUI offenders only.

What is an Ignition Interlock Device?

An interlock device is designed to take a breath sample of the driver every 10 to 30 minutes when the vehicle is being operated to check if there is any alcohol in his or her system. The device is usually installed at the passenger side of the vehicle and is slightly larger than a cell phone. The device is wired to the vehicles ignition and requires the driver to provide a breath sample before the engine is started. This ensures that the person about to drive the vehicle is not drunk. If the device detects alcohol, the engine won’t start.

Arizona Ignition Interlock Device

In the state of Arizona, anyone convicted of drunk driving is required to have an ignition interlock device installed by a company that is authorized by the MVD (Motor Vehicle Division). The Arizona Certified Ignition Interlock Program also requires the uses of a Certified Ignition Interlock Device (CIID) which must be calibrated and inspected by a certified installer every thirty days. Depending on the duration of the installation requirement, the DUI convict is required to have the CIID inspected monthly for the first 3 months and then every other month after that. Drivers who do not comply with the CIID requirements are reported to the Motor Vehicle Division which can result in the extension of the period of use. Failure to comply with the interlock requirements can also lead to the cancellation, suspension or revocation of the driving privileges.

Arizona Department of Transportation

The Arizona Department of Transportation (ADOT) is the government agency in the state of Arizona which is charged with facilitating mobility within the state. Any company manufacturing or installing ignition interlock devices in the state of Arizona must be authorized by ADOT.

ADOT uses special forms and procedures to monitor drivers required to have an interlock device installed under the Certified Ignition Interlock Program. They may issue a replacement drivers license containing the words “Ignition Interlock” to mark your record so that law enforcement agencies and officers are aware of the interlock requirement in the case if you are stopped.

The ignition interlock restrictions are valid on your drivers license only during the period of suspension or revocation. According to Arizona DUI Laws, a restricted driver license may only be used by the DUI convict to operate a vehicle between the place of employment and residence, the place of residence and any secondary or postsecondary school, place of residence and treatment, place of residence and a certified ignition interlock device service facility.
