Key Takeaways:

  • Our knowledgeable Oklahoma City DUI defense attorneys bring over 30 years of combined experience defending clients against DUI, DWI, aggravated DUI, and actual physical control charges with a proven track record of getting charges dismissed or substantially reduced.
  • Former prosecutors on our team understand exactly how the state builds DUI cases, giving us unique insight into weaknesses in evidence, improper police procedures, faulty breathalyzer results, and constitutional violations.
  • Cannon & Associates provides comprehensive defense addressing both your criminal charges and the administrative license suspension process with the Oklahoma Department of Public Safety, protecting your ability to drive while fighting for your freedom.

In Oklahoma, you can be charged with Driving Under the Influence (DUI) if your blood alcohol concentration (BAC) reaches 0.08% or higher, or if you’re impaired by drugs or alcohol to the point you cannot safely operate a vehicle. Even more concerning, you can face Actual Physical Control (APC) charges simply for being in your vehicle while intoxicated, even if you’re not driving. Aggravated DUI charges apply when your BAC exceeds 0.15%, carrying even harsher penalties.

The consequences of a DUI conviction extend far beyond fines and jail time. You face potential license suspension, mandatory alcohol education programs, increased insurance rates, employment difficulties, professional license restrictions, and a permanent criminal record that follows you for years. Our compassionate Oklahoma City DUI defense attorneys at Cannon & Associates understand what’s at stake, and we’re committed to protecting your rights and your future. Call us today to schedule your free case strategy session and learn how we can help.

Your Traffic Stop: Why the Details Matter Now

You’ve already been through the traffic stop and arrest, but here’s what most people don’t realize: what happened during that stop could be the key to your defense. You had constitutional rights during that encounter—the right to remain silent beyond providing basic identification, the right to refuse field sobriety tests (which are subjective and often used against you), and the right to legal counsel before answering investigative questions.

Even more importantly, police needed reasonable suspicion to pull you over in the first place and probable cause to arrest you. If officers violated your constitutional rights or failed to meet these legal requirements, an experienced attorney may be able to get evidence suppressed or even get your charges dismissed entirely.

What Makes Our Oklahoma City DUI Defense Attorneys Different

What sets Cannon & Associates apart is our unique insider perspective. Our team includes former assistant district attorneys and prosecutors who spent years building DUI cases for the state. Now, we use that knowledge to dismantle weak prosecutions and protect the accused. We know exactly what weaknesses to look for, which defenses work, and how to negotiate effectively with prosecutors.

Our trusted Oklahoma City DUI defense attorneys thoroughly investigate every aspect of your case, including whether the traffic stop was lawful, if field sobriety tests were properly administered, whether the breathalyzer was calibrated and maintained correctly, if the officer followed mandatory 15-minute observation periods, whether your constitutional rights were violated, and if medical conditions or other factors could have affected test results.

Building Your Defense Strategy

Every DUI case is unique, and cookie-cutter defenses don’t work. That’s why our criminal defense team develops personalized strategies based on the specific facts of your situation. Common defense approaches include challenging the validity of the traffic stop, questioning the reliability of field sobriety tests, demonstrating breathalyzer malfunctions or improper calibration, proving rising blood alcohol levels (you weren’t over the limit while driving), showing medical conditions that falsely inflated BAC readings, and establishing violations of your Fourth Amendment rights.

Research shows that various factors can affect breathalyzer accuracy, including certain medical conditions, medications, and even diet. Our skilled attorneys work with expert witnesses when necessary to challenge the scientific evidence against you and create reasonable doubt.

Protecting Your Driver’s License

One of the most immediate concerns after a DUI arrest is losing your driving privileges. Oklahoma law gives you only 15 days to request an administrative hearing with the Department of Public Safety to contest your license suspension. This administrative case proceeds separately from your criminal charges, and you need experienced representation at both.

Our knowledgeable Oklahoma City DUI defense attorneys can often successfully argue that no refusal occurred or that proper procedures weren’t followed, helping you keep your license while your criminal case moves forward. Don’t wait—contact us immediately after your arrest to ensure we meet all critical deadlines.

First-Time DUI vs. Repeat Offenses

First-time DUI offenses are typically charged as misdemeanors (unless a child was in the vehicle or injuries occurred), but they still carry serious consequences, including up to one year in jail, fines up to $1,000, license suspension, mandatory alcohol assessment and treatment, increased insurance costs, and a permanent criminal record.

Repeat DUI offenses within ten years escalate to felony charges with prison time, longer license suspensions, and more severe financial penalties. Whether this is your first offense or you’re facing enhanced charges, our experienced attorneys fight tirelessly to achieve the best possible outcome—whether that’s dismissal, reduced charges, or alternative sentencing that protects your freedom and future opportunities.

"My experience with CANNON & ASSOCIATES was absolutely amazing. I hired John Cannon two days before my rebuttal statement was due back to the Staff Judge Advocate. Within that time frame he was able to talk to my Battery and Battalion Commanders, review my evidence, and help me write a rebuttal statement that help prove my case to them, the Brigade Commander and the Post Commanding General. Cannon worked thru the night to help me get the best results for me and my family. Due to his hard work and attention to detail I am still able to continue to serve my country and progress in my military career with no adverse actions on my record. I can not thank him enough on a job well done. Cannon showed me that he was invested in my case and I highly recommend you hire him when you need someone to represent you in a legal matter."
