A DUI in Oklahoma has never been more serious.
we can help.
-
A standard alcohol DUI in Oklahoma is charged at a BAC of 0.08% or higher. Under SB 54, a BAC of 0.15% or higher — or the presence of any aggravating factor like a fender-bender, a teenage passenger, or speeding — now qualifies as aggravated DUI, which is a felony with mandatory jail time even on a first offense. We defend all levels of alcohol DUI and move quickly to challenge the traffic stop, the testing method, and any aggravating factors prosecutors may use to escalate charges.

Oklahoma has a zero-tolerance per se law for cannabis. Any detectable amount of THC or its metabolites in your blood, saliva, or urine at the time of testing is treated as conclusive proof of impairment — no other evidence of impaired driving is required. THC metabolites can remain in your system for days or weeks after last use, long after any impairment has passed. Under SB 54, the previous two-hour testing window has been removed, meaning prosecutors can now use chemical test results from any time after your arrest. Holding a valid OMMA medical marijuana card does not protect you from this charge.
-
SB 54 dramatically expanded the definition of aggravated DUI. Prosecutors now have broad tools to elevate a first-time charge to a felony: a minor accident, a child in the vehicle, reckless driving, excessive speed, or a BAC over 0.15% all qualify. We scrutinize every alleged aggravating factor to keep charges at the right level and protect you from disproportionate consequences.
Oklahoma's laws are among the harshest in the country. We defend DUI cases across Oklahoma, with a unique understanding of how these charges intersect with various aspects of your life.
We can assist with:
-
An administrative license hearing with the Oklahoma Department of Public Safety runs parallel to your criminal case, and the window to request one is short. Acting quickly after an arrest is critical to preserving your driving privileges while your case is pending. We handle both the criminal defense and the DPS administrative process so nothing falls through the cracks.
-
For cannabis business licensees, a DUI charge carries consequences beyond the courtroom. A criminal conviction can jeopardize your OMMA grower, processor, dispensary, or transporter license, and the regulatory exposure can outlast the criminal case itself. Gies Law Firm understands both sides. We coordinate your criminal defense with an awareness of your licensing status from day one so you don't win the case and lose the license.
-
A DUI conviction doesn't have to follow you forever. Depending on the circumstances and the outcome of your case, Oklahoma law may allow for expungement of a DUI charge or conviction. We evaluate your eligibility and handle the process to help you move forward with a clean record.
THC metabolites can stay in your system for days or weeks after use — long after any effect has worn off. Oklahoma's zero-tolerance law treats their presence as proof of impairment. Under SB 54, the state can test you at any point after arrest. An estimated one in ten Oklahomans could be at legal risk on any given day simply because of residual THC in their system from prior, lawful use. Medical marijuana cardholders are not exempt. If you've been charged, this is exactly the kind of case we defend.
You can be sober and still get charged with a cannabis DUI in Oklahoma.
