Louisiana takes a conservative approach to DUIs (referred to as DWI or OWI in Louisiana). This includes mandatory jail time for first offenders (which is often served out by performing community service).
In Louisiana there are two important time periods for determining what is a second offense (known as a look back or wash out period). The period is ten years when a judge reviews an offender’s record for assessing criminal penalties such as fines and jail time. The period is five years for administrative purposes such as license suspensions.
An OWI is considered a third offense in Louisiana if the offender has two prior OWI convictions that occurred within the past ten years. However, license-related penalties depend on the number of priors within that past five years.
