Hiring a DWI Attorney in Baton Rouge
Being arrested for DWI in Louisiana can leave you with a lot of questions very quickly. Will you go to jail? Can you still drive? What happens to your license? What if you refused a breath test? And perhaps most importantly, what should you do now?
After more than 20 years of handling DWI cases in Louisiana, attorney Jim Knipe understands that a DWI arrest creates both legal and personal concerns. For many people, especially those facing a first offense, this may be their first interaction with the criminal justice system.
This guide provides an overview of Louisiana DWI laws, potential penalties, driver's license consequences and what you can expect after an arrest. Each section also connects to more detailed resources if you need information about a particular part of the DWI process.
What Should You Know After a DWI Arrest in Louisiana?
What Is Considered a DWI in Louisiana?
Louisiana law prohibits operating a vehicle while impaired by alcohol, certain drugs, or a combination of substances, as well as operating with a blood alcohol concentration that meets or exceeds limits established by law.
Louisiana law formally calls the offense “operating a vehicle while impaired,” although DWI is the term commonly used when discussing these cases.
For most drivers aged 21 or older, a BAC of 0.08% or higher can establish one basis for a DWI charge. However, a person does not necessarily need a BAC of 0.08% to be arrested or charged if law enforcement alleges that alcohol or another substance impaired the person's ability to operate the vehicle.
This distinction is important because Louisiana DWI cases are not based solely on a breath-test number.

A first DWI conviction in Louisiana can result in a $300 to $1,000 fine, 10 days to six months in jail, probation requirements, substance abuse and driver improvement programs, and possible ignition interlock requirements.
Although the potential jail sentence can sound frightening, Louisiana law allows portions of a first-offense sentence to be suspended when certain requirements are completed.
Higher BAC levels can lead to enhanced penalties. For example, Louisiana law imposes additional consequences when a BAC reaches 0.15% or 0.20%.
Every case is different, which is why the potential statutory penalty does not necessarily tell you what will happen in your individual case.
What Are the Penalties for a First DWI in Louisiana?
Will I Go to Jail for a First DWI in Louisiana?
A first DWI in Louisiana carries possible jail time, but being arrested for a first offense does not automatically mean you will serve the full jail sentence allowed under Louisiana law.
Louisiana's first-offense DWI statute provides for 10 days to six months in jail. However, portions of the sentence may be suspended when the offender satisfies required probation conditions.
Additional mandatory jail requirements may apply to a first DWI conviction in Louisiana when the driver's BAC reaches certain levels or when other circumstances affect the applicable sentencing requirements.
For many first-time offenders, this is one of the most frightening parts of an arrest. Understanding the difference between the possible statutory sentence and what may apply to your specific circumstances is important before assuming the worst.
I understand that a DWI arrest can be frightening and overwhelming, especially when it is your first experience with the criminal justice system. After more than 20 years of handling DWI cases in Louisiana, I’ve seen how much uncertainty people face in the days following an arrest. My job is to help you understand what you’re facing, protect your rights, and give you a clear path forward.

A DWI arrest in Louisiana can trigger driver's license consequences that may occur separately from the criminal case.
For a first administrative violation involving a chemical test result of 0.08% or higher, Louisiana law generally provides for a 180-day driver's license suspension. A first offense involving a BAC of 0.15% or higher can result in a two-year administrative suspension.
The driver's license process is particularly important because it can move independently of the court case. You should not assume that nothing needs to be done with your license until your criminal case is resolved.
Can My Driver's License Be Suspended After a Louisiana DWI?
What Happens if I Refuse a Breath Test in Louisiana?
Refusing a chemical test after a Louisiana DWI arrest can result in separate driver's license consequences and does not automatically prevent the state from pursuing a DWI charge.
Louisiana has an implied-consent law governing chemical testing after certain DWI arrests. Under current Louisiana law, a refusal can generally result in a one-year suspension for a first refusal, although different rules can apply depending on the circumstances.
The state may also rely on evidence other than a breath-test result, including officer observations, field sobriety testing, video evidence and statements made during the investigation.
A refusal therefore creates different legal questions, rather than simply eliminating the DWI case.
Mr. Knipe is an excellent lawyer. He helped me out tremendously when I was wrongly given a DUI, and I didn’t even have to appear in court. I highly recommend Mr. Knipe for anyone going through something similar.

Your blood alcohol concentration can significantly affect a Louisiana DWI case because higher BAC levels can trigger enhanced penalties and longer driver's license suspensions.
While 0.08% is an important threshold for most drivers age 21 and older, Louisiana law also establishes enhanced consequences at higher BAC levels.
A BAC of 0.15% or higher can result in additional mandatory jail requirements and a substantially longer driver's license suspension. A BAC of 0.20% or higher can result in additional penalties, including a higher fine.
The BAC number is important, but it is only one part of the evidence that should be reviewed in a DWI case.
How Does BAC Affect a DWI Charge in Louisiana?
Do I Need an Ignition Interlock Device After a DWI in Louisiana?
An ignition interlock device may be required after a Louisiana DWI and can also be a condition of obtaining certain restricted driving privileges.
An ignition interlock device requires a driver to provide an acceptable breath sample before the vehicle can be started.
Louisiana law uses ignition interlock requirements in several parts of the DWI process, including probation and restricted-license situations. Whether you need one and for how long can depend on your BAC, the type of suspension, and other circumstances surrounding the case.
For someone who depends on driving to work or care for family, understanding ignition interlock and restricted-license options can be particularly important.
Focused on DWI Defense
As a member of the National College for DUI Defense (NCDD), Attorney Jim Knipe is part of a national organization dedicated to advancing the defense of people accused of DUI and DWI offenses. Through the NCDD, he has access to ongoing education, legal developments, defense strategies, and a network of attorneys who focus on this specialized area of law.
For clients, that means working with an attorney who is committed to staying informed about the issues that can affect a DWI case, from traffic stops and field sobriety testing to breath and blood evidence and constitutional rights.
If you have been arrested for DWI, you deserve an attorney who understands what is at stake and knows what to look for in your case.

After a DWI arrest in Louisiana, you should address both the criminal charge and any driver's license issues while preserving information and evidence related to the arrest. A DWI case may involve much more than a BAC result.
An attorney reviewing the case may examine why the vehicle was stopped, body-camera and dash-camera footage, field sobriety testing, breath or blood testing procedures, officer observations, statements made during the investigation and whether law enforcement followed the proper procedures.
It is also important to determine whether there are deadlines or administrative issues involving your driving privileges.
The sooner you understand what you are actually facing, the easier it becomes to separate the legal realities of the case from the fear and uncertainty that often follow an arrest.
What Should I Do After a DWI Arrest in Louisiana?
When Should I Contact a Louisiana DWI Attorney?
You should consider speaking with a Louisiana DWI attorney soon after an arrest so you can understand the criminal charge, your driver's license situation and the options available based on the facts of your case.
For many first-time offenders, the most difficult part of a DWI arrest is not knowing what happens next.
Jim Knipe has more than 20 years of experience handling DWI matters in Louisiana and understands both the legal consequences and the personal concerns that can follow an arrest.
