  • I have been arrested for DUI. What do I do now?We always recommend that you consult with an attorney immediately to make sure that your rights are preserved. Specifically, you will need to apply for a DPS hearing within (15) days from the date of the arrest to avoid forfeiting your driver's license. You should also retain any documentation that you have been provided by the arresting officer and bring it with you when you meet with us.
  • Will I Lose My License?Not necessarily - you can contest the revocation of your drivers license, but you must do so within 15 days of the date of your arrest. If we represent you, we will agressively defend your license in your DPS hearing. See our page on Driver's Licenses for more information.
  • Can I get a DUI for one of my prescriptions?Yes. You can still be charged with DUI-Drugs even if the drug in question was prescribed legally. Under Oklahoma Law, there is no distinction between a DUI for illegal drugs and prescription drugs. The only question is whether that drug impaired your ability to drive safely. We can, however, use the fact that you are prescribed a drug to argue that you were not impaired.
  • What happens if I refused a BAC (Blood Alcohol Concentration) Test?There is no criminal penalty for refusing to submit to a warrantless BAC test, but your refusal may be used as evidence against you in a trial. Additionally, you may be subject to enhanced administrative penalties such as a longer revocation of your drivers license or a longer period where you have to have an interlock device in your car.
  • The officer seized my driver license. Can I continue to drive?Maybe. If your driver license was seized and it was valid and unexpired at the time, the officer will indicate on your copy of the affidavit that the affidavit will serve as a temporary driver license for a period of thirty (30) days. This temporary license authorizes you to drive for thirty (30) calendar days from the date the officer serves you with the affidavit, provided you are not suspended or revoked for some other reason. DPS will try to revoke your license and if you do nothing, they will. We always request a hearing on behalf of our client's and contest the revocation. If we win, which we generally do, you won't lose your license at all.

    Zach Smith is an amazing attorney. Zach represented me and he made sure he was there with me every step. I wasn’t sure what to expect and after meeting with him, he told me what to expect in every detail. When in court I was so nervous at first but with Zach there I got relaxed and confident. He made it all work great and solved the issue. Thanks so much. Great job Zach Smith.

    My Son David was arrested for DUI, pretty intense. He was in accident and had some injuries to his head. They gave him a Breath test on site and had him walk the line with the injury. He was taken to jail. I asked the bail guy, whos the best DUI attorney in Tulsa, he said the DUIGUY. Zach was amazing, and was able to get the DUI dismissed, but more importantly he knew the DLicense was key at that very moment. He won the DL hearing this meant his license would not be revoked, nor would he be required to have a a blow device if convicted, of course he we won the case. But if we had lost, winning the DL hearing meant no devices etc as mentioned. AS a result of everything Davids driving record is clean, and will not show any any arrest for a DUI. If you are faced with a situation like we were faced with, if you dont go with the best, then you are gambling with the future of the people involved. His fees were awesome, his feedback was crucial and specific. He knows this area, he is an Expert in this Field. You have to go with the best, that would be Zach.

    This man, Sabah Khalaf, is not JUST an attorney; he is a brilliant, wise, kind and highly-evolved human being. He was my lawyer - yes. And in that capacity he acted knowledgeably and quickly and got the job done better than any other attorney could have. He was amazing. A miracle. But I still say what impressed me the most was his kindness.

    I hired Zack after i was arrested for a DUI. Due to my profession, i was very scared about what might happen to me as well as my job. Zach was a straight shooter, knew exactly how my case would turn out before the court dates and was very good at keeping me calm throughout this very hectic and nerve wrecking time in my life. Zack was able to get me a deferred sentence and also won my Driver’s license hearing to that my DL will never be revoked. I will never require to have a blow device installed in my vehicle, something you would normally have to do for an additional 18 months after a 6 month suspension (if i had lost). Zack was honest with me during the entire process and delivered what he promised. He is an excellent DUI attorney and would highly recommend him!

  • Wes


    Well, if the five stars do not speak for themselves; Let me just fill you in on how good Sabah is… I went to court once for a small situation and saw a long line of people without attorneys. We skipped that and were in/out with the best possible outcome ever. I am still bouncing with joy over the weight lifted off my shoulders, because I picked the best lawyer ever! Do what he recommends that you do, and feel confident that he has an understanding of the law fit for awards. A Very upstanding gentleman; you won’t regret.

Tulsa DUI Guys Zach Smith and Sabah Khalaf

Zach and Sabah are both from Oklahoma who took similar paths in life. They both went to law school and started their legal careers in the Tulsa County DA’s Office. Their time at the DA’s Office led them to similar conclusions; they wanted to help people.

Sabah casually knew Zach before he started as a prosecutor in 2010 and it was during their interactions as Adversaries, they fostered a relationship that led to Sabah teaming up with Zach in 2018.

Zach and Sabah really love helping people put their mistakes behind them and helping them pave the way to a fresh start and bountiful future.
