How long can the state use a prior DWI convictions against me?

If you have prior DWI convictions, the prosecution can use offenses from 10, 20, even 30 years ago to enhance your current DWI conviction, which increases the grade of the DWI offense you are presently being prosecuted for. This increases the range of punishment available to the state as well as the consequences of the current charge.

However, prior DWI convictions, where the offense was committed prior to January 1, 1984, cannot be used for enhancement purposes when the sentence resulted in probation and the probation was never revoked.
