Reliable DUI Defense Attorneys Assisting With Ignition Interlock Device Matters in Tucson, AZ
If you have been convicted of driving under the influence (DUI), you may be required to install a breath alcohol ignition interlock device (IID) in any vehicle you drive once you are allowed to operate a vehicle again. You may be allowed to drive right away after a DUI conviction if your driver's license is not suspended. However, you may have to wait a period of time to reinstate your license.

How IIDs Work
When an IID is installed in your vehicle, it will be connected directly to the engine, and a breath test device will be attached to your dashboard. Before you can start your car, you must blow into the device, which tests your breath for alcohol. If your breath is alcohol-free, you will be able to turn on the engine. However, if alcohol is detected, the vehicle's ignition will be locked for a certain period of time, and the device will store the data regarding your blood alcohol concentration (BAC). You must also blow into the device periodically while you drive. If you fail to do so, or if the device detects alcohol on your breath while the vehicle is on, the device will record this data and sound an alarm until it receives a clean breath sample or the vehicle is turned off.
The IID installer and maintenance provider you use will periodically send the data from your IID to the Department of Transportation. If there is any evidence of tampering with the device or its ability to detect alcohol, you may have to use an IID for a longer duration, or you may lose your driving privileges.
Arizona Law on IIDs
You will be required to install an IID in your vehicle if you are convicted of a DUI for:
- Having a BAC .08 percent or more;
- Being underage and having a BAC above zero; or
- Being a commercial driver's license holder and having a BAC of .04 percent or more.
If you are convicted of a DUI, your driver's license may be suspended for a period of time. Once your license is reinstated, or you are granted limited driving privileges, then you will have 30 days to install an IID in any vehicle you drive. You may be required to use the device for one year or more.
If you are caught driving your car or another vehicle without an IID, the requirement to use the IID may be extended, or you may lose your driving privileges.
The Costs of an IID
You will be responsible for the costs of installing the IID at a business certified by the Arizona Motor Vehicle Department. This installation can cost hundreds of dollars. You also must return to a certified business to have the IID inspected and re-calibrated every 90 days. There may be a fee for each visit.
When an IID is Not Required
If you were convicted of a DUI based on an illegal or prescription drug in your system rather than alcohol, then Arizona judges have the discretion to require an IID or not.
Ignition Interlock Device FAQs
The cost of an ignition interlock device will include installation and leasing. Pricing will vary depending on the provider of the device, but monthly costs can average around $80 to $120, with installation fees typically costing around $50 to $150. These costs can add up, as even first-time offenders must use an interlock device for at least a year.
The length of time you need to have an interlock ignition device in your vehicle will vary based on the severity of the offense you were convicted of, ranging from six months to two years. The Arizona Motor Vehicle Department will assess different factors to determine the length of the ignition interlock requirement, such as your BAC and whether or not you have a history of prior offenses.
Ignition interlock devices are required after a conviction of DUI in Arizona. Therefore, if you have been charged with DUI, you can avoid mandatory installation of an ignition interlock device by challenging the underlying offense. A skilled DUI defense lawyer may be able to seek a dismissal of charges based on the circumstances of your case, whether it involves contesting an unlawful traffic stop or attacking the accuracy of a chemical test.
If you fail the initial interlock test, you will not be able to start your vehicle, and your failed breath test will be reported to the court. Additionally, you may be asked to take random retests while driving, with any violations being reported to the court. Failing to challenge a violation could result in an extension of the ignition interlock period.
Hiring an attorney is highly advisable for challenging allegations of DUI or an ignition interlock violation. An attorney who is skilled at handling drunk driving charges can look for mitigating circumstances or contest the underlying charge, potentially shielding you from harsh consequences.
An ignition interlock device will prevent your vehicle from starting if you have a BAC of .02 or greater. Additionally, the device will prompt you to retest on the road at certain intervals to make sure that you are still sober.
In Arizona, convicted DUI offenders must install ignition interlock devices to regain their driving privileges. When violations are reported to the courts via an ignition interlock device, drivers may face the suspension of their driving privileges or an extension of the interlock period.
Arizona does not make hardship exemptions for ignition interlock devices. However, first-time DUI offenders may be able to have a device removed after six months instead of a year when certain requirements are met, such as completing an alcohol education program.
