DUI in Louisiana
State-specific overview · Criminal Law
Louisiana's DUI law uses 0.08% BAC but uniquely allows first-time offenders to avoid a criminal conviction through deferred adjudication.
How Louisiana treats DUI
Louisiana law prohibits driving with a 0.08% BAC or higher (0.04% for commercial drivers, 0.02% for drivers under 21). A distinctive feature allows first-time DUI offenders to enter a deferred prosecution agreement, potentially avoiding a permanent criminal conviction if they complete probation and treatment requirements. Louisiana imposes mandatory minimum jail time, fines, and license suspension for DUI convictions, with enhanced penalties for repeat offenses or high BAC levels.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
