DUI Penalties for Commercial Driver’s License Holders

What Happens When A Commercial Driver’s License Holder Is Arrested For DUI?

If a commercial driver’s license holder is arrested and/or convicted of a DUI, their commercial driver’s license is taken away for one year. It is possible to attempt to fight that but depending on the facts of the case, depending on blood alcohol content, it may be inevitable that they are going to lose their commercial driver’s license for at least that amount of time on a first-time offense.

What Are The Consequences Of A Second-time Offense On A Commercial Driver’s License?

Second-time offense, at least out of the State of Arizona, is a lifetime ban from having a commercial driver’s license. That doesn’t mean that someone who has a commercial driver’s license is not able to drive their non-commercial vehicle. They can still drive their civilian vehicle but it takes away their ability to operate a commercial vehicle on a commercial driver’s license.

What Are Some Other Consequences For CDL License Holders After A DUI Conviction?

Simply for being arrested and having a commercial driver’s license, it does not matter whether the person was actually operating a commercial vehicle at the time. If a person has a commercial driver’s license but was driving around in their civilian car, got pulled over and was arrested for a DUI in their civilian vehicle, the Arizona Department of Transportation is going to attempt to suspend their commercial driver’s license as well for one year. That can be fought but if a person is convicted of a DUI, they are going to end up losing their commercial driver’s license for at least one year as long as that was their first DUI offense.

The problem is that if the commercial driver’s license holder ends up being convicted of a DUI, in nearly every circumstance, a person who is convicted is going to be required to have an ignition interlock device on any vehicle they operate for anywhere from six months up to 18 months on a first-time misdemeanor offense. There is no work exception, which means that if someone has a commercial driver’s license, depending on what type of DUI conviction they have received, if any, there may come a point where they are eligible to reinstate their commercial driver’s license. However, they would have to have an ignition interlock device on their commercial vehicle.

For most people who do not own their own commercial vehicle, their employer is not going to be willing to allow someone to install an ignition interlock device on a commercial vehicle.

When talking about DUIs in the State of Arizona, people with a commercial driver’s license tend to have a lot more problems than the average person, especially if that is their primary form of employment. Most people do need to find other professions, either within the same company or find employment elsewhere because there are huge pitfalls and huge downfalls to dealing with a DUI in Arizona while being a possessor of a commercial driver’s license.

brian sloan on the cover of attorney at law magazine

“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.
