Most people think drunk driving charges stem solely around being caught driving with a BAC (blood alcohol concentration) of at least 0.08. It is true that every state in the nation has a law prohibiting people to operate motor vehicles while in excess of the 0.08 law. However, there are other circumstances in which Oklahoma citizens could be charged with DUI.
In addition to the 0.08 DUI law, Oklahoma also has an aggravated or enhanced DUI law. Police can charge you with this type of DUI if your sobriety test reveals a BAC in excess of 0.17. This charge typically results in severe penalties, making it vital to consult with an attorney.
Underage drivers can also face serious consequences if caught driving under the influence of alcohol. In fact, the BAC limit for drivers under 21 is only 0.02, meaning even one or two mild drinks can result in drunk driving charges.
Defendants with prior drunk driving charges should also be aware that in Oklahoma, you can be charged with felony DUI for only your second offense. If you have been convicted of at least one prior DUI within ten years of your current charges, you will probably be looking at felony charges.
