2026 Louisiana DWI Law Changes: What Drivers Need to Know

Every Louisiana legislative session brings changes to criminal laws, traffic laws, and DWI-related procedures. Some changes are major. Others are technical. For people arrested for DWI, the important question is usually not, “What did the Legislature pass?” but rather, “Does this affect my case?”

During the 2026 Regular Session, Louisiana passed several new laws related to DWI, impaired driving, ignition interlock devices, court procedure, and release after arrest.

This article explains the six main DWI-related law changes and what they may mean in practical terms.

Quick Summary of the 2026 Louisiana DWI Law Changes

Act	Topic	Practical Impact
Act 8	Repeal of certain additional DWI fines	Removes certain extra fine provisions from Louisiana DWI penalty statutes
Act 49	Ignition interlock device offenses	Updates ignition interlock offense language to include court-ordered conditions of release
Act 117	Enhanced penalties for repeat DWI offenders with serious prior driving-related offenses	Creates harsher sentencing exposure in certain repeat-offender situations
Act 651	Governor’s Task Force on Impaired Driving	Creates a statewide task force to study and recommend impaired-driving policies
Act 723	“Jada’s Law” sober release requirement	Allows certain DWI arrestees to be held until safe release is feasible
Act 812	“Intoxicated or impaired” terminology	Adds “impaired” language to certain DWI-related statutes and responsive verdict provisions

1. Act 8: Repeal of Certain Additional DWI Fines

Act 8 repeals certain additional fine provisions found in Louisiana’s DWI penalty statutes.

This does not eliminate the basic fines and penalties for DWI. Louisiana still has fines, jail exposure, probation conditions, license consequences, and other requirements depending on the offense level.

The practical point is that this law removes certain additional fine provisions from the DWI sentencing structure that would lead to the right to a jury trial in misdemeanor DWI cases. This Act corrects the erroneous act created by the Legislature in 2025 when it passed a law that created an additional fine on misdemeanor DWI cases which resulted in the right to a jury trial being established. Read about it here.

What This Means Practically

For most people charged with DWI, this change will not be the most important issue in the case. It just means that there is no longer a right to a jury trial in misdemeanor DWI cases. Trial would be by judge only.

2. Act 49: Ignition Interlock Device Offenses

Act 49 updates Louisiana’s ignition interlock offense statute.

The change adds a reference to Code of Criminal Procedure Article 320(C), making clear that ignition interlock restrictions may arise not only from probation or other provisions of law, but also from certain court-ordered release conditions.

The law continues to prohibit a restricted person from operating, leasing, or borrowing a motor vehicle unless it is equipped with a functioning ignition interlock device. It also continues to prohibit asking another person to blow into the ignition interlock device or start the vehicle for the restricted person.

What This Means Practically

This is important because ignition interlock issues can arise at different stages of a DWI case.

A person may be required to use an ignition interlock device because of:

• license reinstatement requirements
• probation conditions
• court orders
• conditions of bond
• high BAC allegations
• refusal-related issues
• repeat-offense allegations

Violating ignition interlock restrictions can create new legal problems separate from the original DWI charge.

3. Act 117: Enhanced Penalties for Certain Repeat DWI Offenders

Act 117 is one of the more serious changes.

This law addresses enhanced penalties for repeat DWI offenders who have prior convictions for certain serious driving-related offenses, including vehicular homicide, third degree feticide, or first degree vehicular negligent injuring, or equivalent laws from another state.

The law increases sentencing exposure in certain second, third, fourth, or subsequent offense DWI situations when those serious prior offenses are involved.

What This Means Practically

This law will not affect the ordinary first-offense DWI case.

Its real impact is in serious repeat-offender cases where the person has a prior conviction for one of the specified driving-related offenses.

In those situations, the sentencing consequences can become much more severe.

For example, Act 117 increases the mandatory sentencing exposure in certain second-offense DWI cases where the first offense was vehicular homicide, third degree feticide, or first degree vehicular negligent injuring. It also creates or modifies enhanced penalty provisions for certain third, fourth, or subsequent offense cases.

Practical Takeaway

This is not a technical change for the people it affects. If a person has a prior serious driving-related conviction and is later charged with DWI, the case needs careful review.

Prior convictions, dates, offense classifications, and whether the prior offense qualifies under the statute can become critical issues.

4. Act 651: Governor’s Task Force on Impaired Driving

Act 651 creates the Governor’s Task Force on Impaired Driving.

The task force is designed to study impaired driving involving alcohol, drugs, or a combination of alcohol and drugs. It includes representatives from various agencies and organizations involved in public safety, enforcement, prosecution, prevention, treatment, highway safety, and impaired driving policy.

The task force is authorized to review impaired-driving data, analyze trends, evaluate countermeasures, and make recommendations.

What This Means Practically

This law does not directly change the penalty for an individual DWI charge.

However, it may affect future policy.

The task force may study issues such as:

• DWI arrest rates
• prosecution and conviction rates
• chemical test refusals
• ignition interlock use
• substance abuse treatment
• drug-impaired driving
• alcohol-related crashes
• enforcement strategies
• future legislative changes

Practical Takeaway

This law is more about future policy than immediate courtroom procedure.

However, it signals that Louisiana is continuing to focus on impaired-driving enforcement and prevention. Future DWI law changes may come from recommendations made by this task force.

5. Act 723: “Jada’s Law” and Sober Release After DWI Arrest

Act 723 creates R.S. 14:98.9, known as “Jada’s Law.”

This law provides that after an arrest for operating while impaired under R.S. 14:98 or 14:98.6, the custodial agency may hold an individual who is presumed to be under the influence of alcohol until safe release is feasible.

The law also states that it should not be interpreted to deny or restrict a person’s entitlement to bail or limit a court’s authority to impose additional release conditions.

The law does not apply to individuals who are seventeen years old or younger.

What This Means Practically

This law addresses what happens immediately after a DWI arrest.

In plain English, if a person is arrested for DWI and is still presumed to be under the influence, the custodial agency may hold the person until safe release is feasible.

This does not mean a person loses the right to bail. It also does not mean the person can be held indefinitely. But it gives custodial agencies authority to consider safe release in the immediate aftermath of a DWI arrest.

Practical Takeaway

For many people arrested for DWI, the first few hours after arrest are confusing. This law may affect when a person is released after arrest, especially if the agency believes the person is still under the influence.

It may also cause family members to ask why someone has not been released immediately after bond is addressed.

6. Act 812: Adding “Impaired” to DWI-Related Language

Act 812 updates several Louisiana statutes to add “impaired” language alongside “intoxicated.”

This includes provisions involving city, parish, and municipal court prosecutions, certain alcohol-related court costs, admissibility of chemical testing documents, and responsive verdicts for vehicular negligent injuring and first degree vehicular negligent injuring.

What This Means Practically

This is largely a terminology and clarification law.

Louisiana’s DWI statute is commonly referred to as “driving while intoxicated,” but impairment can involve alcohol, drugs, or a combination of substances.

By adding “impaired” in certain places, the law better reflects how these cases are often prosecuted.

Why It Matters

DWI is not limited to alcohol cases.

A person can be accused of operating while impaired based on:

• alcohol
• controlled substances
• prescription medication
• a combination of alcohol and drugs

This law reinforces that impaired driving cases are not always traditional alcohol-only cases.

Do These New DWI Laws Apply to Pending Cases?

That depends on the specific law, the effective date, the date of the alleged offense, and the nature of the issue.

Some changes may apply prospectively. Others may affect procedure or terminology. Sentencing-related changes require careful analysis.

If you were arrested before a law changed, do not assume the new law automatically applies to your case. Likewise, do not assume it does not apply.

The timing matters.

What Did Not Change?

Even with these new laws, many core Louisiana DWI rules remain the same.

For example:

• DWI cases can still involve both criminal court and administrative license issues.
• A DWI arrest can still trigger driver’s license consequences.
• Chemical testing and refusal issues remain important.
• Ignition interlock issues can still arise in many cases.
• Prior convictions can still dramatically change sentencing exposure.
• Every case still depends on the facts.

What Should Someone Do After a DWI Arrest in Louisiana?

If you are arrested for DWI in Louisiana, the most important thing is not to rely on rumors, internet comments, or what happened to someone else.

A DWI case may involve:

• criminal charges
• driver’s license suspension
• administrative hearing deadlines
• ignition interlock issues
• insurance consequences
• employment concerns
• professional licensing issues

The facts of the stop, arrest, testing, prior history, and timing all matter.

Bottom Line

The 2026 Louisiana legislative session brought several DWI-related law changes. Some are technical. Some affect future policy. Some may matter significantly in specific cases, especially repeat-offender cases involving serious prior driving-related convictions.

The most important takeaway is this:

Louisiana DWI law continues to evolve, and people charged with DWI should not assume they understand the law based on old information, internet advice, or someone else’s experience.

If you are facing a DWI charge in Louisiana, it is important to understand the specific law that applies to your case and the deadlines that may affect your driver’s license and court proceedings.
