DUI Countermeasures: differences between court jail sentences and jail time actually served and available alternative sanctions in select California counties.

Introduction And Methods: Jail sentences and actual jail times were compared for 2006 California driving under the influence of alcohol or drugs (DUI) offenders from select counties using matched data from Department of Motor Vehicles (DMV), court, and sheriff databases. Additionally, alternative sanctions to jail were investigated.

Results: Jail sentences reported by courts were consistently longer than actual jail time.
