If you take a chemical test and score over .08 (for adults) or .02 (persons under 21), or if you refuse to submit to a chemical test, then the state will take action to revoke your driver’s license for a period of up to three years. The length of revocation varies. For the first revocation, it is six months with the possibility of modification to allow you to drive with an ignition interlock device on your vehicle. For the second revocation within five years, it is a one-year revocation that cannot be modified. For the third revocation within five years, it is a three-year revocation that cannot be modified for the first year. After the first year, the court can modify the revocation, but only with the installation of an interlock device on every vehicle you drive. Make sure to contact the Oklahoma DUI defense attorneys.
