What happens after a Louisiana DWI arrest?
Separate the criminal charge, the OMV license process, and the evidence-preservation work that can begin immediately.
Source review: October 16, 2026A Louisiana DWI arrest can create a separate 30-day written-request deadline for an OMV administrative hearing. Read the temporary receipt and notice immediately.
What this pathway evaluates
Louisiana now titles R.S. 14:98 as operating a vehicle while impaired. The public and many court records still use DWI. The statute covers several distinct theories, including impairment by alcohol, a blood-alcohol concentration of 0.08 percent or more, and impairment by drugs or a combination of substances.
An arrest can generate two tracks. The criminal case concerns guilt, admissibility, sentence, and related conditions. The administrative track concerns driving privileges and is handled through the Office of Motor Vehicles process. A filing in one track does not automatically protect rights in the other.
The first strategic job is not choosing a defense from a list. It is preserving the record, identifying the exact charged theory, calculating deadlines from source documents, and testing each possible route against the evidence that actually exists.
Issue map
Criminal docket
Collect the citation or bill, bond papers, court notice, docket number, charging statute, and every scheduled date. Confirm the court and section rather than relying on an arresting agency's shorthand.
License track
Keep the seized-license receipt and every OMV notice. R.S. 32:667 generally gives no more than 30 days from arrest to make a written administrative-hearing request, subject to a narrow later-request provision for documented inability.
Evidence clock
Body camera, dash camera, 911 audio, CAD, private surveillance, instrument data, biological samples, dispatch recordings, and tow or booking records may have different retention periods. Identify the custodian and send specific preservation requests early.
Theory map
Operation, the stop, detention, arrest, statements, searches, field testing, chemical testing, medical explanations, prior offenses, enhancements, and mitigation are separate issues. A weakness in one does not necessarily defeat every prosecution theory.
Questions this route should answer
Does the criminal court handle the license suspension?
Not by itself. The criminal case and the OMV administrative process are distinct. Track both from their own notices, deadlines, and records.
Should I wait for the police report?
Do not let a report delay deadline calculation or evidence preservation. Use the documents already received, then reconcile the report and media when produced.
Does an arrest mean the State can prove DWI?
No. The State must prove an authorized statutory theory with admissible evidence. But an arrest also does not establish that a particular defense applies.
