The results of the breath or blood test will largely determine the charges brought and the possible sentences.  The so-called "per se" offense (driving over .08%) is defined by the blood-alchohol level; the "DUI" offense (Driving Under the Influence) is partially proven with a rebuttable presumption of intoxication if the result is over .08%.

More FAQS on DUI

 Field Sobriety Tests - Do you have to submit to these tests?
Every single DUI case is different, but as a general rule, it is almost always better to take the test in Oklahoma. However, if you have several convictions for DUI and fail time is more of the concern versus saving your Oklahoma driver's license, then you should not take the test unless you think you will pass it.

· To Take the Test or not, that is the question?
· What are Field Sobriety Tests?
· Horizontal Gaze Nystagmus (HGN)
· Walk & Turn
· One Leg Stand
· Counting Backwards (not a validated test)
· Alphabet (not a validated test)
· Finger Count (not a validated test)
· Stationary Balance (i.e. Rhomberg) (not a validated test)
· Field Test Realities

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

New DUI Laws
Effective Nov 1, 2011

If you refused to take the breath or blood test or the result was a .15 or higher BAC, you may be required to install an ignition interlock device on your car for two years. If you have prior license revocations, you may be required to install an ignition interlock device on your vehicle for up to 8 years. Contact our office at 405-231-5600 now to see if these new laws apply to you. Remember, we must take action within 15 days of your arrest to prevent license suspension.
