If you are facing a Louisiana DWI charge in 2026, the operative criminal statute is La. R.S. 14:98, with the related impaired-driving provisions at La. R.S. 14:98.1 through 14:98.7. A separate administrative driver's license suspension runs through the Louisiana Office of Motor Vehicles under La. R.S. 32:667 with a 30-day window to request a hearing.
This post walks through the statutory framework, the parallel administrative track, and the procedural questions the first 72 hours raise. It does not predict outcomes; eligibility for any specific relief depends on the facts and the charge.
La. R.S. 14:98: the baseline DWI offense
La. R.S. 14:98 is the principal Louisiana DWI statute. The statute reaches operation of a motor vehicle while under the influence of alcoholic beverages, controlled dangerous substances, or any combination thereof; with a BAC of 0.08 or above for adult drivers; and at the elevated 0.15 threshold for enhanced penalties.
The penalty structure escalates with prior offenses. A first conviction is generally a misdemeanor. A second conviction within the cleansing period is treated more severely. A third conviction within the cleansing period is a felony under the statute. La. R.S. 14:98.1 through 14:98.7 spell out the per-offense penalties and the cleansing-period rules.
The 0.15 elevated threshold
La. R.S. 14:98 sets an elevated threshold at 0.15 that carries enhanced penalties on top of the baseline. The elevated threshold attaches additional minimum jail terms and certain interlock requirements that exceed the baseline.
The OMV 30-day administrative window
The Louisiana administrative track runs through the Office of Motor Vehicles under La. R.S. 32:667. The arresting officer typically serves a notice of suspension at or near the time of arrest. The driver has 30 days to request an administrative hearing. Failure to request within the 30-day window typically results in the administrative suspension taking effect by operation of statute.
Louisiana's 30-day window is longer than the windows in many neighboring states, but it is still a statutory deadline. The criminal case timeline does not pause the OMV clock.
What the first 72 hours typically involve
The first three days after a Louisiana DWI arrest usually involve:
- Release on bond or under bond conditions the court sets
- Receipt of a citation or summons identifying the criminal charges and the first court appearance
- Service of the OMV administrative notice that starts the 30-day clock
- Initial decisions about chemical-test source documentation (breath, blood, or refusal)
The 30-day OMV window is the deadline most commonly missed when drivers assume the criminal track addresses the license.
Common misreads we see Louisiana DWI defendants make
Misread one: assuming the criminal court resolves the license issue. The criminal track and the OMV track run in parallel. The OMV process attaches its own consequences regardless of the criminal track outcome.
Misread two: confusing the cleansing period with the prior-offense calculation. Louisiana's prior-offense calculation under La. R.S. 14:98 turns on the cleansing-period rules. The exact prior history controls the charge classification, not just the count of priors.
Misread three: assuming a refusal eliminates the administrative process. A refusal has its own consequences under La. R.S. 32:667. The administrative consequences for a refusal can be more substantial than the consequences for a qualifying chemical test result.
Practical next steps in the first 72 hours
Three steps consistently move a Louisiana DWI matter forward.
Step one: identify the OMV 30-day deadline. Find the administrative notice and read the service date. The 30-day window runs from that date.
Step two: organize the criminal paperwork. Identify the citation, the first court appearance date, the bond conditions, and the venue. The court paperwork carries the operative criminal-track deadlines.
Step three: preserve chemical-test documentation. Whether the case involves a breath test, blood draw, or refusal, the chemical-test documentation is central to the prosecution's case under La. R.S. 14:98.

A note on Louisiana expungement
Louisiana also has a general expungement framework at Code of Criminal Procedure articles 971 through 995 that may reach certain DWI convictions in limited circumstances after the underlying matter has been resolved. The expungement framework does not eliminate the live consequences of a current DWI charge.
Louisiana DWI second and third offenses
La. R.S. 14:98.2 and 14:98.3 spell out the elevated penalty postures for second and third Louisiana DWI offenses. The escalation rules turn on the cleansing-period analysis under La. R.S. 14:98 and on whether the prior offenses occurred within the statutory lookback window.
A third Louisiana DWI conviction within the cleansing period is generally a felony under La. R.S. 14:98.3. The felony posture carries enhanced penalties including a longer minimum jail term and a longer license suspension under the administrative process. The cleansing-period analysis controls whether the current charge is a felony, and an incorrect prior-history calculation can change the charge classification.
La. R.S. 14:98.5 and the elevated 0.20 threshold
Louisiana attaches additional enhanced penalties at the elevated 0.20 BAC threshold under La. R.S. 14:98.5. The elevated threshold carries minimum jail terms above the baseline and certain interlock requirements that exceed the standard DWI penalty.
The 0.20 threshold is independent of the prior-offense calculation. A first offense at 0.20 or above carries the elevated penalty posture without regard to prior history. The threshold is established by chemical-test result, which makes the chemical-test documentation particularly important in these cases.
Louisiana interlock requirements
The Louisiana Office of Motor Vehicles administers an ignition interlock requirement that attaches to certain DWI-related license-status postures. The interlock requirement runs in parallel with the criminal case and is part of the administrative track. The interlock paperwork is separate from the criminal-case paperwork, and the petitioner who does not engage with the OMV process may find interlock attaches by default in certain postures.
A note on Louisiana parish-court venue
Louisiana DWI cases are prosecuted in the district court of the parish where the stop occurred. The parish-court venue is uniform on paper, but the local docket and procedural practices vary across the state's 64 parishes. Petitioners should consult the local district court's published procedures before any filing.
