What Are the Penalties for a First DWI in Louisiana?

A first DWI in Louisiana can result in a $300 to $1,000 fine, 10 days to six months in jail, probation requirements, driver education and substance abuse programs, ignition interlock requirements, and suspension of your driver’s license.

If this is your first DWI arrest, those penalties can sound overwhelming. After more than 20 years of handling DWI cases in Louisiana, I understand that most first-time offenders are not only worried about the legal consequences. They are also concerned about their job, their family, their ability to drive, and what this arrest could mean for their future.

The important thing to remember is that an arrest is not the same as a conviction, and the maximum penalties listed in Louisiana law do not necessarily tell you exactly what will happen in your case.

What Are the Legal Consequences of a First DWI Conviction?

Louisiana law provides for a fine of $300 to $1,000 and a jail sentence of 10 days to six months for a first DWI conviction.

However, Louisiana law allows portions of the jail sentence to be suspended when certain requirements are completed.

Those requirements can include:

• 48 hours in jail or at least 32 hours of court-approved community service
• A court-approved substance abuse program
• A court-approved driver improvement program
• Compliance with applicable ignition interlock requirements

You can review the Louisiana law governing first-offense DWI penalties.

Will I Go to Jail for a First DWI in Louisiana?

A first DWI carries possible jail time, but a first-time offender does not automatically serve the full 10-day to six-month sentence.

This is one of the most common concerns I hear from people after a first DWI arrest.

For many first offenses, Louisiana law allows part of the sentence to be suspended if the person completes the required probation conditions. The outcome depends on the facts of the case, including the BAC level and whether any enhanced penalties apply.

Will I Lose My Driver’s License After a First DWI in Louisiana?

A first DWI arrest can result in the suspension or restriction of your Louisiana driver’s license.

For many people in Baton Rouge and the surrounding area, this is one of their most immediate concerns because they rely on their vehicles to get to work, care for family, and manage everyday responsibilities.

The length of the suspension can depend on your BAC and whether you submitted to chemical testing. A first administrative suspension involving a chemical test result of 0.08% or higher is generally 180 days. Higher BAC levels and test refusals can result in longer suspensions.

Driver’s license consequences can also operate separately from the criminal DWI case, which is why it is important to address them early.

Are the Penalties Higher if My BAC Was 0.15% or More?

Yes, Louisiana imposes additional penalties when a first-offense DWI involves a BAC of 0.15% or higher.

If your BAC was at least 0.15% but less than 0.20%, Louisiana law requires additional jail time that cannot be suspended and can impose a longer driver’s license suspension.

If your BAC was 0.20% or higher, the fine increases to $750 to $1,000, along with additional mandatory jail time and other requirements.

These higher BAC thresholds are important because not every first DWI carries the same potential consequences.

Is a First DWI a Felony in Louisiana?

A typical first DWI in Louisiana is a misdemeanor, not a felony.

That does not mean it should be taken lightly. A first DWI can still affect your driving privileges, finances, insurance, and criminal record.

At the same time, I believe it is important for first-time offenders to keep the situation in perspective. In more than 20 years handling DWI cases in Louisiana, I have represented people from virtually every walk of life who never expected to face a criminal charge.

One arrest does not define who you are.

What Should I Do After a First DWI Arrest in Baton Rouge?

After a first DWI arrest in Baton Rouge, you should understand both the criminal charge and the potential driver’s license consequences before assuming the worst.

A DWI case involves more than simply looking at a BAC number. Depending on the circumstances, an attorney may examine:

• The reason for the traffic stop
• Body-camera or dash-camera footage
• Field sobriety testing
• Breath, blood, or urine testing
• Whether proper testing procedures were followed
• Whether chemical testing was refused
• Statements made during the investigation

The facts of your specific arrest matter.
