Driving after a DUI and the Ignition Interlock Device

Interviewer: Let’s discuss the ignition interlock device. When is the driver required to install the device and for how long must they maintain it?

The Device Must Be Installed in Your Vehicle for 6 Months to 2 Years

Brian Sloan: Everyone convicted of a DUI—whether it’s a regular DUI, extreme DUI, super extreme DUI, aggravated DUI—all drivers must have an ignition interlock device installed on their vehicle for a certain period of time. The device must be maintained for anywhere from six months to upwards of two years.

In Some Cases, the Only Way to Avoid the Installation of the Device to Plead Guilty, Which Results in a One Year Suspension

There is one exception and that is if you were to be convicted of DUI, drugs or medications, specifically, pursuing to Arizona Revised Statute 28-1381A3. If that person were to be convicted solely without offense, which is that you were in physical control of the car with any drug metabolized in your system, there is a may be a way of avoiding the installation of the device.

If a person is pleading guilty to just that charge then they’re going to end up losing their license for one year. So, it’s a trade-off. Yes, you may not have to do the ignition interlock device, but you are going to lose your license for one year. And there’s no restricted license available. You cannot drive to and from work and school for one year.

Refusals Face the One Year Suspension—If the Ignition Interlock Device Is Installed and the Driver Carries Sr22 Insurance, They May Have a Restricted License for the Last 9 Months of the Suspension

Actually, it’s a license revocation. The only other time when you technically need to have an ignition interlock device is if at the time that you were arrested, you refused the requested blood, breath or urine test by the officer. Then you end up losing your license for one year. It is suspended for one year for refusing.

You may be eligible to get a restricted ignition air-lock device license for the last nine months of that one year along with Sr22 high risk insurance. That’s the only situation where a person does not necessarily have to be convicted of a DUI in order to have that ignition interlock device.

There Are Some Situations Where the Driver Can Reduce the Time They Must Maintain the Ignition Interlock Device

But in nearly all of the situations, anyone convicted of a DUI will have to install the ignition interlock device. The current standing of the law is that if a person is convicted of a regular DUI, which is when they were in natural physical control of the car and their blood alcohol level is between a .08 and a .149. Although, technically, it could be below a point 08;because that indicates they were impaired to a slightest degree.

They are required to have an ignition interlock device on any vehicle they operated for one year. However, the law allows them to uninstall the device after six months if they do that first six months correctly. Now, abiding by the rules for six months correctly means that they blow into the ignition interlock device every time, including when they are at their destination.

You Will Have to Maintain the Device for the Full Time Imposed If There Was an Accident at the Time the DUI Was Issued

The only other exception to that is that if you were in an accident when you were arrested and unfortunately, that could mean that you were the cause of the accident or that you were truly a victim of a car accident. If the police officer filled out a citation a certain way and notified the Motor Vehicle Division that you were somehow involved in an accident, you are not eligible to get that six months off of your ignition air-lock device.

“I am one of only a handful of Phoenix DUI Lawyers that focuses solely on DUI Defense representation.”

I have spent my entire career SOLELY focused on Arizona DUI Defense Representation, having personally defended more than 4,400 Driving Under the Influence (DUI) clients in the past 19+ years.

If you’re looking for a Divorce Attorney, Tax Attorney, Civil Attorney, etc., I can comfortably say, "I’m not the one for you." I ONLY defend DUI cases in most of Maricopa County, Arizona.

Coming up with traditional, as well as outside-the-box motions and defenses for my clients, often with good results, is the hallmark of my practice.

Lawyers that say they are "aggressive" or "will fight for you" are a dime a dozen. They use these phrases because it is a proven advertising phrase. Being "aggressive" isn’t the same as being good, and is often used to put on a show to hide the fact that they aren’t doing anything meaningful for the client.

The same is true for the Lawyers claiming to do DUI Defense, and Criminal Cases, and Accident Cases, and Divorces, etc. A Jack-of-all-Trades is a master of none! By handling all sorts of cases, they take away from their ability to truly focus on DUIs, and keep up-to-date on the latest changes in DUI Defense Representation.

What I offer is intelligent, quality DUI Defense at an exceptional price. Unlike many other law firms, if you hire The Law Offices of Brian D. Sloan, you actually get me representing you, doing all the work, and working the case. You aren’t hiring one guy with all the experience, but getting the underling with very little knowledge or experience.

I work seven days a week on my client’s cases, and spend hours laying all my thoughts out for my clients in writing, so they can understand their options, and my recommendations. No other DUI Lawyer in the state does this. I try to do what I can to go above-and-beyond for my clients. I hate when the businesses I deal with nickel-and-dime me with hidden costs, and I take pride in not doing that to my clients.

I have not only taught other lawyers how to do DUI Defense Representation at statewide seminars, but I have produced DUI Legal Guides used by defense lawyers across Arizona.

I am one of Arizona's most award-winning DUI Defense Lawyers, as well as being recognized nationally. I was the only DUI Defense Lawyer in the United States named a "Power Lawyer" in a 2022 issue of USA Today

There are no other private Lawyers in Arizona that have personally defended more DUI cases than I have. And as a bonus, I offer a very reasonable flat rate for my legal services, with a payment plan, and without any hidden charges. This guarantees that I offer some of the most competitive rates among all Arizona DUI Attorneys, while being a well-documented and preeminent leader in the field of DUI Defense Representation.

Over the years, countless people have come to me after discovering that their first lawyer made a mistake, gave them false hope or false promises, or simply took their money and didn't do much to advance their case. And you would be surprised at how often this happens.

So, instead of wasting time and money on the wrong DUI Defense Attorney, do yourself a favor and get the proven and well-recognized best DUI Lawyer in Phoenix and the surrounding areas of Maricopa County.

You can reach me on my personal cell phone at 480-720-7839 for a Free ‘In Depth’ Consultation.

I personally defend DUI cases in urban Maricopa County City, Town, and Justice Courts, including:

Ahwatukee / Agua Fria / Arcadia Biltmore / Avondale / Buckeye / Chandler / Country Meadows / Desert Ridge / Dreamy Draw / Downtown / East Mesa / El Centro / Encanto / Gilbert / Glendale / Goodyear / Guadalupe / Highland / Kyrene / Litchfield Park / Maryvale / McDowell Mountain / Mesa / Moon Valley / North Mesa / Peoria / Phoenix / Queen Creek / San Marcos / San Tan / South Mountain / Scottsdale / Tempe / University Lakes / West McDowell / West Mesa / White Tank

For any other Courts in the State of Arizona, including Felony cases, I would recommend my associates on The Arizona DUI Team, whom I work closely with, but I am not the one personally representing the client.
