Louisiana First Offense DWI

Louisiana First Offense DWI Laws Explained in Easy to Understand Simple Terms

Louisiana’s DWI laws are designed to deter and penalize driving while intoxicated (DWI), which is defined as operating a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher for most drivers, 0.02% for drivers under the age of 21, and 0.04% for commercial vehicle drivers. The law also covers impairment due to other substances, not just alcohol. Penalties for DWI in Louisiana escalate with the number of offenses. A first offense can lead to fines, mandatory participation in a substance abuse program, and possible jail time. A driver’s license suspension is also typical, starting from 90 days for a first offense.

For repeat offenders, Louisiana imposes more severe consequences, including longer jail sentences, higher fines, longer license suspensions, and installing an ignition interlock device on the offender’s vehicle. A third offense is considered a felony, and the penalties increase dramatically, potentially including state prison time. Additionally, Louisiana has an implied consent law, meaning that drivers automatically consent to field sobriety tests and chemical tests (like breath, blood, or urine tests) by driving on Louisiana roads. Refusal to submit to these tests when suspected of DWI can lead to immediate license suspension and other penalties. These laws reflect Louisiana’s commitment to road safety and reducing alcohol-related accidents.

Key Aspects of a First Offense DWI in Louisiana

  • Penalties: For a first offense DWI in Louisiana, penalties typically include a fine ranging from $300 to $1,000. The offender may also face jail time from 10 days to six months, though jail time can sometimes be waived or reduced if the offender agrees to complete a court-approved substance abuse program and a driver improvement program.
  • License Suspension: The driver’s license suspension is a significant part of the penalties for a first offense DWI. The suspension period for a first offense is generally 90 days. This suspension serves as a strong deterrent against driving under the influence and aims to ensure that the offender has time to reflect on the seriousness of the offense.
  • Mandatory Substance Abuse Evaluation and Community Service: Offenders are required to undergo a substance abuse evaluation and may be mandated to participate in a substance abuse program. Additionally, community service is often required, varying in hours, which helps to reinforce the social responsibilities and consequences of impaired driving. These measures are designed to help prevent future DWI offenses by addressing the underlying issues related to substance use.

First Offense DWI Penalties

In Louisiana, the penalties for a first offense DWI (Driving While Intoxicated) can be quite severe and vary depending on the specifics of the case, particularly the blood alcohol concentration (BAC) of the offender at the time of arrest.

For a first-time DWI offense in Louisiana, here are the general penalties:

For a first-time DWI offense in Louisiana, here are the general penalties:

  • Fines: The offender can be fined between $300 and $1,000.
  • Jail Time: There is a possibility of jail time ranging from 10 days to 6 months. However, this can sometimes be suspended if certain conditions are met, such as completing community service or a substance abuse program.
  • Community Service: Offenders may be required to perform community service, particularly activities like litter abatement.
  • Driver’s License Suspension: The offender’s driver’s license can be suspended for up to 12 months. The suspension could be for two years for those with a BAC of 0.20% or higher.
  • Ignition Interlock Device (IID): Installation of an IID may be required, especially if the BAC was high.
  • Substance Abuse and Driver Improvement Programs: Participation in approved substance abuse and driver improvement programs is typically mandated.

Probation terms might include mandatory jail time (minimum of 48 hours which cannot be suspended) or community service. Higher BAC levels result in stricter penalties. For instance, if the BAC is 0.15% or higher but less than 0.20%, at least 48 hours of the sentence must be served without the possibility of parole, probation, or suspension of the sentence. If the BAC is 0.20% or more, the fine increases to between $750 and $1,000, and the same minimum jail time applies.

It’s important to note that these penalties can be influenced by the specifics of the arrest, such as the presence of minors in the vehicle or any injuries caused, which can lead to more severe consequences​ (dui.drivinglaws.org)​​ (legis.la)​​ (ambeaulaw)​​ (louisianacourtrecords)​.

Underage First Offense DWI

In Louisiana, the penalties for a first offense underage DWI (Driving While Intoxicated) are specifically tailored for individuals under the age of 21 who are caught driving with a blood alcohol concentration (BAC) of 0.02% or higher. The laws reflect a zero-tolerance approach to underage drinking and driving, recognizing the increased risks associated with it.

For underage drivers convicted of a first DWI offense, the penalties typically include:

  • A fine ranging from $100 to $250.
  • Mandatory participation in a court-approved substance abuse and driver improvement program.
  • Potential jail time, although the focus is often more on educational and rehabilitative measures rather than incarceration for first offenders.

If there are subsequent offenses, the penalties increase in severity, including higher fines and possible jail terms. It’s also important to note that having a minor in the vehicle at the time of the offense can lead to additional penalties under child endangerment laws, which make any sentence non-suspendable and mandatory​ (Bloom Legal)​​ (Barkemeyer Law Firm)​.

The specific penalties can vary somewhat based on the court’s findings and the circumstances of the offense, but the overarching aim is to address the behavior through corrective educational measures while imposing fines that underscore the seriousness of the offense. For more detailed and updated information, consulting with a local attorney or checking the latest resources from the Louisiana state legislature could provide further guidance.

CDL First Offense DWI Penalties


In Louisiana, the penalties for a first-offense DWI for commercial drivers holding a Commercial Driver’s License (CDL) are notably stricter than those for non-commercial drivers. For CDL holders, the legal limit for blood alcohol content (BAC) while operating a commercial vehicle is 0.04%, which is half the standard limit of 0.08% for other drivers.

If a CDL holder is convicted of a DWI with a BAC of 0.04% or higher while operating a commercial vehicle, or 0.08% or higher in any vehicle, they face severe consequences. The penalties include a mandatory one-year disqualification of their CDL for the first offense. This disqualification applies even if the CDL holder was driving a non-commercial vehicle at the time of the offense. Additional consequences can include fines, possible jail time, and increased insurance rates. If the offense involves refusing a breathalyzer test, it can also lead to CDL disqualification, regardless of the vehicle being driven at the time​ (SuperLawyers.com)​.

These penalties are designed to uphold higher safety standards for CDL holders, given their operating larger, potentially more hazardous vehicles and their professional reliance on maintaining a clean driving record​ (Keith T. Whiddon, Attorney at Law, LLC)​.

Ignition Interlock Requirements First Offense DWI


In Louisiana, the law mandates that first-time DWI offenders must have an ignition interlock device (IID) installed in their vehicles as part of the conditions for maintaining or reinstating their driving privileges after a DWI conviction. This requirement is set forth under Louisiana Revised Statute § 32:378.2, which stipulates that any person whose driver’s license is suspended or revoked due to a DWI conviction, refusal to submit to chemical tests, or having a BAC above legal limits must provide proof of an IID installation to obtain a restricted driver’s license.

The device must be maintained for a minimum of 12 months, depending on the specific circumstances of the case, such as the offender’s blood alcohol content at the time of the offense. For instance, if a first-time offender registers a BAC of 0.20 percent or higher, the requirement for the IID extends throughout the entire two-year suspension period, but it must be in place for at least the first 12 months.

Additionally, Louisiana allows certain exceptions, such as for those who need to drive company vehicles as part of their job. In such cases, vehicles owned by the employer and used by the employee do not require an IID installation, provided that both the employer is informed of the driving restriction and the court approves this exception.

Violations related to tampering with or circumventing an IID can lead to further legal consequences, including extended license suspension and potential jail time.

For more detailed legal guidance and requirements related to IIDs in Louisiana, especially in complex cases, consulting with a legal expert or DUI attorney is advisable​ (The Norris Law Group)​​ (Guardian Ignition Interlock)​.

Implied Consent Law

Louisiana’s implied consent law states that anyone who operates a motor vehicle on public highways is deemed to have consented to chemical testing (blood, breath, urine) to determine alcohol or drug levels if arrested under suspicion of DWI. Refusing the test results in an automatic license suspension. The law is stringent to ensure compliance with DWI testing procedures and to support law enforcement in managing driving under the influence cases effectively​ (cardonelaw)​.

DWI Class Requirements

In Louisiana, individuals convicted of a DWI are generally required to complete a DWI education program as part of their penalties. The class’s specifics depend on the offense’s severity and details, but for a first-time offender, an 8-hour DWI education class is most commonly mandated. There are also provisions for taking these classes online, which can be convenient for those who might face difficulties attending in person due to schedule constraints or geographical limitations.

For offenders who have been through the DWI process more than once, a longer class of 16 hours may be required. Additionally, a 1-hour Victim Impact Panel might also be mandated, which aims to provide offenders with personal insights from victims of drunk driving, thus highlighting the real-world consequences of their actions.

Individuals need to confirm with the court, probation officer, or legal counsel whether an online course would fulfill their specific requirements, as acceptance can vary​ (DUI Law Center)​. For more detailed information or to register for a class, resources like the DUI Law Center offer various options for both online and in-person classes tailored to meet state requirements and personal circumstances​ (duiprocess)​.

Driver License Hearing

In Louisiana, when someone is arrested for a DWI and their driver’s license is suspended, they have the right to request an administrative hearing through the Department of Public Safety and Corrections (DPSC). This administrative hearing is a separate process from any criminal proceedings related to the DWI. The purpose of the hearing is to determine issues like whether the law enforcement officer had reasonable grounds to believe the motorist was driving under the influence, whether the motorist was properly arrested, and whether the motorist was correctly advised of their rights.

During the hearing, the motorist can challenge the suspension of their driver’s license. Documents such as the DPSC Certification of Arrest Report, the Arrestee’s Rights Form, and the results of the Intoxilyzer Breath Test are typically presented. While law enforcement officers usually do not testify, the administrative law judge reviews these records to decide whether the license should remain suspended or be returned.

The motorist has 30 days from the date of arrest to request this hearing. If the judge decides to uphold the suspension, the motorist can then file a petition for judicial review in civil district court within 30 days from receiving the judge’s decision. Failing to challenge the decision within these time limits will result in the suspension becoming final​ (Gaynellwilliamslaw)​.

Final Thoughts

A first offense DWI in Louisiana carries significant legal consequences that are designed to deter impaired driving and ensure public safety. The penalties are structured to be punitive but also incorporate rehabilitative elements. Here are some key takeaways:

  • Severity of Penalties: First-time offenders face fines, possible jail time, and mandatory participation in educational programs. Specific penalties can vary based on the blood alcohol content (BAC) at the time of the offense, with higher BAC levels leading to harsher consequences.
  • License Suspension: Offenders typically experience a suspension of their driver’s license. The length of suspension can increase with the BAC level, and offenders may need to install an ignition interlock device to regain limited driving privileges.
  • Implied Consent Law: Louisiana’s implied consent law means that all drivers agree to chemical testing by holding a driver’s license. Refusal to undergo these tests when requested can lead to immediate license suspension and other penalties.
  • Underage and CDL Drivers: Special rules apply to underage drivers and those holding a commercial driver’s license (CDL), with stricter BAC limits and potentially more severe penalties for violations.
  • Administrative Hearings: Offenders have the right to challenge their license suspension at an administrative hearing, which is a separate process from criminal proceedings but crucial for contesting the terms of a license suspension.

The approach is comprehensive, aiming to address both the legal and public health aspects of DWI offenses. It’s advisable for those facing such charges to seek legal advice to navigate the complexities of the law and to understand fully the repercussions of a DWI conviction in Louisiana.
