Arizona Penalties For DUI - First Time Offender
The statute requires the court to sentence a first time offender to serve not less than ten consecutive days in jail. However, the court may suspend all but twenty-four consecutive hours of the sentence if the offender completes an alcohol abuse screening. Since the statute stipulates consecutive hours the court cannot give credit for any time served on the day of the arrest.

The statutes also require a fine of not less than four hundred twenty-five dollars plus administrative fees and court costs. The court may also order the offender to perform up to forty hours of community service and attend a class sponsored by Mothers Against Drunk Driving, known as the Victim Impact Panel. Usually the offender will also be placed on twelve months of probation as well. 

Penalties For a Second Offense
A person convicted of a second DUI offense within sixty months of the first, or a first offense and has previously been convicted in another state for a first offense that complies with an Arizona law, is guilty of a class one misdemeanor. The dates of commission of the offenses are the dispositive dates in determining the sixty-month period. A second-time offender is subject to the same sanctions as a first-time offender regarding an alcohol screening, counseling, education, treatment, and payment.
