The DWI Law in Louisiana
Drunk driving is charged as DWI in Louisiana, at a blood alcohol level of 0.08 or more.
Driving in Louisiana is consent to a breath or blood test when an officer has cause to suspect DWI; the license case that follows a refusal or a failed test is run by the Office of Motor Vehicles, separately from the criminal case.
Who Makes DWI Arrests in Union Parish
The Union Parish Sheriff's Office and the agencies that report for Farmerville, Bernice and Marion make the DWI arrests in Union Parish.
Together, the two agencies in Union Parish with all twelve months of 2023 on file reported 148 arrests to the FBI that year, all offenses together; the FBI's count for Union Parish does not break DWI out.
