They are all located in Ohio and none of them tolerate drinking alcohol and/or doing drugs and driving a motor vehicle. In Oklahoma, a driver can be charged with a driving under the influence (DUI) offense in a number of ways, and not all include simply drinking alcohol. If you've been arrested and charged with a DUI crime in Oklahoma, here is some information to help assist you understand the laws and where you can go for legal help.

Ignition Interlock Device after First-Offense DUI Conviction

If you have been convicted of first-time DUI, you may be required to install an ignition interlock device (IID) under certain circumstances. Named for a young woman who was killed in 2009 by an intoxicated driver on the Kilpatrick Turnpike in north Oklahoma City, the Erin Swezey Act requires drivers to install an IID on their vehicles if they either:

  • had a blood alcohol level (BAC) of .15 percent or higher;
  • refused to take a chemical test (blood or breath) at the request of an investigating officer.

Simply put, a person convicted of a DUI would have their Oklahoma driver’s license suspended for six months and would be retired to have an IID on their vehicle for a total of 18 months.

Second and Third-Time DUI Convictions and IID Requirements

If you are unlucky enough to have a second or third DUI conviction in Oklahoma, you'll have more to worry about than just jail time and probation.

On a second offense DUI, your license will be suspended for a year and you'll have to have an IID installed on any vehicle you own or operate for a total of five years.

If you think "third time is a charm," it isn't when it comes to DUI sentencing. If you've been convicted of a third DUI in three years, your license will be suspended for three years, and the IID sentence will be five years after the three-year suspension has been served, or a total of eight years if your driving privileges have been modified.
