The criminal case
DUI penalties in Louisiana
The offense, qualifying priors and statutory conditions matter—not just an arrest count.
DUI penalties in Louisiana depend on the charged offense and its statutory conditions. Prior convictions, their dates, and aggravating factors may change the applicable rule. An arrest count alone does not establish the offense tier, and a minimum sentence is not the complete sentencing range. The cited rules below are not predictions of a particular case’s outcome.
The lookback period
- How far back priors count
- Not published yet. We show a figure only once it has been confirmed against the official source and dated.This varies widely between states — from a few years to a lifetime — so it is not safe to assume a national figure.
Penalty rules by offense number
- First offense
- Not published yet. We show a figure only once it has been confirmed against the official source and dated.
- Second offense
- Not published yet. We show a figure only once it has been confirmed against the official source and dated.
- Third offense
- Not published yet. We show a figure only once it has been confirmed against the official source and dated.
Driving privileges, ignition interlock and insurance requirements need separate review under their own rules. A commercial-driving restriction may have different triggers from a restriction on an ordinary licence. No consequence is assumed merely because it appears in this list.
- Ignition interlock, first offense
- Not published yet. We show a figure only once it has been confirmed against the official source and dated.
The two legal questions
The criminal charge and driving privileges can involve different proceedings. The notice, order and cited rule identify the applicable process.
Driving privileges
The licence case
- Forum
- The agency or court identified by the applicable licence proceeding
- Clock
- Check the applicable notice or order for the deadline and its starting event
- Deadline to request a hearing
- For an administrative hearing under R.S. 32:667–668 after a DWI arrest, the written request to the Louisiana Department of Public Safety and Corrections must be made within 30 days from the date of arrest.
- The period runs from arrest, not from a later court appearance or the arrival of delayed chemical-test results.
- A person unable to request a hearing within 30 days because of incarceration, hospitalization or another cause acceptable to the department may submit documentation establishing that inability. A request under that exception must be submitted no later than 90 days from arrest; this is not an automatic 90-day extension.
- Suspension under the cited rule
- Not published yet. We show a figure only once it has been confirmed against the official source and dated.
