How quickly must I respond after a DWI arrest?

The most time-critical deadline is the administrative hearing request: 30 days after notice of suspension in Louisiana [§ 32:667]. Missing this deadline waives your right to contest the license suspension, regardless of what happens in the criminal case.

Will I lose my license immediately?

Louisiana imposes an administrative suspension of 180 days (failed test); 365 days (refusal) for a first offense [§ 32:667]. A form of restricted driving privileges may be available. This is separate from any criminal license suspension.

What is the difference between the criminal case and the administrative case?

The criminal case is prosecuted in court and can result in jail, fines, and a criminal record. The administrative case is about your driver's license and is handled separately. You can win one and lose the other — they have different standards of proof and different deadlines.

Can DWI charges be reduced?

Outcomes depend on evidentiary strength, procedural compliance by the officer, BAC level, and other factors. An experienced attorney can evaluate whether the evidence supports a motion to suppress, a plea to a lesser charge, or trial.

Does a DWI stay on my record permanently?

First-offense DWI conviction may be set aside and dismissed after 5 years from completion of sentence if no subsequent convictions, under La. C.Cr.P. art. 894. This is a dismissal/set aside, not a traditional expungement. Second and subsequent convictions are not eligible. [§ 14:98].

DUI Is Like 2 Cases in 1

A DUI arrest triggers two separate proceedings that run at the same time. The criminal case decides guilt, penalties, and your record. The administrative case decides whether your license is suspended — often on a much shorter deadline. Missing a step in one track can limit your options in the other, which is why understanding both paths from the start matters.

fees & compliance

Two tracks run at once: the court case and license/administrative deadlines. Deadlines, procedures, and penalties vary by state.

The two tracks: criminal and administrative

Track 1: Criminal prosecution

The criminal case is a court proceeding where the state must prove DWI beyond a reasonable doubt. Louisiana's per se BAC limit is 0.08 §14:98, but you can also be charged based on impairment regardless of BAC. A first offense is classified as a misdemeanor.

Track 2: Administrative license action

The administrative action is handled separately from the criminal case §32:667. It can result in license suspension even if the criminal case is eventually dismissed. You have 30 days after notice of suspension to request a hearing to contest the suspension.

⚠The administrative hearing deadline is short — 30 days after notice of suspension. Missing this deadline waives your right to contest the license suspension, regardless of what happens in the criminal case.

What triggers enhanced penalties

BAC ≥ 0.15 (mandatory IID, higher fines)
Child under 13 in vehicle (§ 14:98.6 — separate felony)
DWI causing death (vehicular homicide § 14:32.1)
DWI causing serious bodily injury (§ 14:98.5)
Prior offenses within 10-year lookback

Implied consent and chemical testing

Louisiana has an Implied consent law: by driving on Louisiana roads, you have implicitly consented to chemical testing when lawfully arrested for DWI. Refusing the test carries its own consequences: 365-day license suspension. In Louisiana, refusal to submit to chemical testing is admissible as evidence at trial.

BAC thresholds that matter

	Category	BAC Limit
Standard per se	0.08 §14:98	DWI charge without other evidence of impairment
Enhanced penalty	0.15 §14:98	Higher minimum penalties and longer license suspension
Under 21	0.02	Zero tolerance violation
Commercial (CDL)	0.04 §49 C.F.R. § 383.51	CDL disqualification

Why timing matters most

DWI cases are unusually time-sensitive. The administrative hearing deadline begins running from the date of arrest or notice — not from the first court date. Evidence (dashcam footage, witness recollections, calibration records) can deteriorate. Early attorney involvement can preserve options that disappear with delay.

⚠If you have been arrested for DWI in Louisiana, the most time-critical step is requesting the administrative hearing within 30 days after notice of suspension. Consult an attorney immediately — this deadline cannot be extended.
