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 St. Martin Parish
The St. Martin Parish Sheriff's Office and the agencies that report for Breaux Bridge and St. Martinville make the DWI arrests in St. Martin Parish.
Together, the two agencies in St. Martin Parish with all twelve months of 2025 on file reported 1,716 arrests to the FBI that year, all offenses together; the FBI's count for St. Martin Parish does not break DWI out.
The Broussard Police Department and the Arnaudville Police Department are each listed by the FBI across several counties including St. Martin Parish, so their arrests are not broken out for St. Martin Parish here.
Booking After a DWI Arrest in St. Martin Parish
A driver arrested for DWI and kept in custody goes to the parish jail, whichever agency made the arrest. The jail, run by the St. Martin Parish Sheriff's Office, held about 190 people on an average day in 2023 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at stmartinsheriff.org/correctional/corrections-parish-jail-st-martinv.... The St. Martin Parish inmate search guide covers the jail in full.
The Court Case
The District Attorney files the charge, and the case is heard in the District Court.
The District Attorney's page SearchSystems verified is at 16jda.com, phone (337) 394-2220.
The court records page SearchSystems verified for the parish is at stmartinparishclerkofcourt.com.usitestat.com, phone (337) 394-2210.
Louisiana has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
The court case is only half the record. The Office of Motor Vehicles runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Louisiana Office of Motor Vehicles keeps the driving record the conviction goes on.
The Records a DWI Leaves
- The arrest report: from the agency that made the arrest, under the Louisiana Public Records Law.
- The court file: from the District Court, kept by the Clerk of Court.
- The driving record: from the Louisiana Office of Motor Vehicles.
