A second DWI offense in Louisiana is treated with significantly greater seriousness than a first. The penalties are harsher, mandatory jail time applies, and long-term consequences increase sharply. While a first-time offense may result in some leniency or alternative sentencing, a second arrest within a ten-year period signals a pattern of risky behavior. The state responds with mandatory jail terms, extended license suspensions, and more restrictive conditions for driving privileges.
Louisiana law separates DWI penalties into two tracks: criminal penalties, which are handled by the court, and administrative penalties, which are handled by the Louisiana Department of Public Safety. Both processes may apply independently. That means a driver can face license suspension even if they’re not ultimately convicted in court.
This article explains the full scope of what happens after a second DWI in Louisiana — covering the penalties, jail requirements, license consequences, insurance implications, and more — with the goal of helping people understand what to expect from the process.
Criminal Penalties for a Second DWI Offense in Louisiana
Louisiana classifies a second DWI offense within a ten-year period as a misdemeanor, but it brings mandatory penalties that are far more severe than a first offense. The court system imposes criminal consequences, and the law limits judicial discretion in many areas.
Key criminal penalties for a second offense include:
- Mandatory jail sentence ranging from 30 days to 6 months
- A minimum of 48 hours must be served in jail with no option for suspension
- Fines between $750 and $1,000
- Court costs and administrative fees
- Required participation in a substance abuse program
- Mandatory driver improvement or DWI education course
- Up to 240 hours of community service
- Potential home incarceration or electronic monitoring
Judges may allow alternatives such as home incarceration for a portion of the sentence or allow work-release programs, but the minimum 48 hours in jail is non-negotiable under Louisiana law. Probation may be offered for the remainder of the jail sentence, but strict conditions apply.
Second DWI convictions are permanent and will appear on criminal background checks, influencing future legal consequences and personal opportunities.
Administrative Penalties and License Suspension After a Second DWI
Separate from the criminal court system, Louisiana imposes administrative penalties on drivers who are arrested for a second DWI. These are handled by the Louisiana Department of Public Safety and can take effect even if the criminal case has not yet concluded.
Administrative penalties typically include:
- License suspension for 1 year if BAC is 0.08% or higher
- Suspension for 2 years if BAC is 0.20% or more
- 2-year suspension for chemical test refusal
- Mandatory ignition interlock device (IID) upon reinstatement
- SR-22 insurance filing required for high-risk driver status
- Reinstatement fees and compliance paperwork
Drivers will usually receive a temporary license valid for 30 days, along with a notice of suspension. Unless the driver formally requests an administrative hearing within 15 days of arrest, the suspension goes into effect automatically.
Administrative penalties operate independently from criminal court outcomes. That means even if the driver avoids conviction, the suspension can still apply.
Refusing a Chemical Test and Its Effects on Penalties
Under Louisiana’s implied consent law, any person who operates a motor vehicle on public roads has already consented to chemical testing if lawfully arrested for suspicion of DWI. Refusing to take a breath, blood, or urine test carries automatic penalties, especially for repeat offenders.
For a second refusal, the penalties include:
- Automatic 2-year license suspension, even without a court conviction
- No eligibility for a hardship license for 45 days
- Potential denial of any restricted driving privileges, depending on the case
- Increased SR-22 insurance duration and interlock requirements
Refusal is often treated as an aggravating factor. Courts may consider it when determining sentencing, and it may influence how prosecutors approach plea discussions.
Because of these rules, second-time offenders who refuse testing typically face longer suspensions and stricter reinstatement requirements than those who comply with testing but still exceed the legal BAC limit.
High BAC Enhancements and Additional Penalties
Louisiana law sets additional penalties for drivers who test with a BAC of 0.15% or higher, and especially for those who exceed 0.20%. For second offenses, these enhancements further reduce the possibility of leniency.
Penalties for high BAC levels include:
- Mandatory minimum jail time of 96 hours for BAC 0.20% or higher
- License suspension extended to 4 years
- Mandatory ignition interlock device for entire duration of restricted driving
- Limited eligibility for hardship or restricted licenses
- Potential increase in insurance requirements and monitoring
Judges have little flexibility when high BAC levels are involved. In these cases, the court must follow enhanced sentencing guidelines, often requiring additional jail time and longer supervision periods.
Hardship License Eligibility After a Second DWI
While license suspension is mandatory, Louisiana law provides a path for limited driving through a hardship license — a restricted license that allows driving for essential needs such as work, school, or medical care. However, the conditions for obtaining one after a second DWI are much stricter than for first-time offenders.
To qualify for a hardship license after a second DWI, the driver must:
- Serve 45 days of the license suspension first (if eligible)
- Provide proof of ignition interlock device installation
- Submit SR-22 insurance documentation
- Pay all reinstatement and application fees
- Possibly complete a substance abuse program or counseling
- Not be involved in an accident that caused serious injury or death
In some cases, the court or the Department of Public Safety may deny the hardship license altogether — especially if aggravating factors like test refusal or extremely high BAC levels are present.
Even when granted, the license comes with strict limitations and requires full compliance with all imposed conditions.
Long-Term Consequences of a Second DWI Conviction
The effects of a second DWI in Louisiana extend far beyond the jail sentence or license suspension. Long-term consequences may impact a person’s daily life, financial stability, and future legal standing.
Key long-term consequences include:
- Permanent criminal record – which can affect job opportunities, especially in transportation, healthcare, or government roles
- SR-22 insurance requirement – typically required for 3 to 5 years after reinstatement
- Higher car insurance premiums – often doubling or tripling existing rates
- Difficulty obtaining professional licenses – especially in law, education, or medicine
- Restricted travel opportunities – some countries deny visas to those with DWI records
- Felony exposure – a third DWI becomes a felony, carrying a minimum 1-year prison sentence
A second offense also removes many options that may have been available for a first offense — such as reduced charges, diversion programs, or deferred adjudication. It cements a driver’s place in the state system as a repeat offender, making future cases far more serious.
Differences Between Criminal and Administrative Penalties
Louisiana’s DWI system separates penalties into two major categories: criminal (court-imposed) and administrative (license-related). Both tracks function independently and can result in separate penalties for the same incident.
| Penalty Track | Handled By | Key Outcomes |
|---|---|---|
| Criminal Penalties | Criminal Court | Jail, fines, probation, community service |
| Administrative Penalties | Louisiana Dept. of Public Safety | License suspension, IID, SR-22 requirements |
Key differences:
- Administrative penalties often begin immediately, before any court case is decided
- A driver may lose their license even if the court case is dismissed
- Reinstatement for both systems requires separate compliance steps
Understanding this split is important, as many drivers mistakenly assume that resolving the court case ends the entire process — when in fact, administrative actions may still apply.

Conclusion
A second DWI in Louisiana brings significant consequences, including mandatory jail time, steep fines, long-term license suspension, and a criminal record that can impact multiple areas of life. The state treats second offenses as a serious threat to public safety and imposes mandatory sentencing rules that reduce judicial flexibility. In addition to criminal penalties, the administrative process triggers automatic license suspension and insurance requirements, regardless of the court outcome.
