If you have been accused of drunk driving, and you don't believe you were intoxicated or you want an analysis of the State's evidence against you, you should contact an attorney. If you signed a plea agreement, it may not be too late to change your plea to "Not Guilty.". If you didn't sign anything, all the better. Remember, even old convictions are subject to challenge.
A conviction for operating a motor vehicle while intoxicated entails both criminal penalties and mandatory license suspensions. The criminal penalties and license suspensions become increasingly severe as the number of offenses increase. For example, a 90-day license suspension is typical for first time offenders, but three convictions within five years of one another results in a mandatory 10-year suspension.
