In Louisiana, the traditional offense is "underage driving under the influence of alcohol" (UDUI), or "driving while intoxicated" (DWI). UDUI requires only a .02 blood alcohol level and is used to charge persons under the age of 21 years old. DWI requires a blood alcohol level of .08. If you submit to the chemical test and test above these levels, you are presumed to be intoxicated.
If you have any questions about an arrest or pending charges, please contact the DWI lawyers at Babcock Patners.
