Louisiana DWI/DUI Laws and BAC Limits

BAC Louisiana law sets the legal limit at 0.08 BAC for drivers 21 and older. Drivers under 21 face a zero-tolerance standard of 0.02. Commercial drivers operating vehicles that require a CDL are held to a stricter 0.04 limit.

The Louisiana statute governing drunk driving is La. R.S. 14:98. The formal term in Louisiana law is DWI (Driving While Intoxicated). You will also see the terms OWI (Operating While Intoxicated) and OUI used, particularly in older case filings. All three refer to the same statutory offense. "DUI" is not a Louisiana statutory term but is widely used colloquially and is treated as interchangeable.

Under Louisiana's per se DWI rule, a BAC at or above the legal threshold is itself evidence of impairment. The prosecutor or plaintiff does not need to show other signs of impaired driving if the BAC test is at or above the limit. A first-offense DWI is a misdemeanor. Subsequent offenses escalate to felony charges, with mandatory minimum jail time beginning on the second offense.

Two enhanced criminal charges apply when a drunk driver causes serious harm. Vehicular Negligent Injuring under La. R.S. 14:39.1 applies when a drunk driver causes serious bodily injury. First-degree vehicular negligent injuring carries up to five years at hard labor. Vehicular Homicide under La. R.S. 14:32.1 applies when a drunk driver causes death. When the driver's BAC was 0.15 or higher at the time of the crash, the sentence can reach 30 years at hard labor. These criminal charges run parallel to your civil claim. They are separate proceedings.

Louisiana also prohibits open alcoholic beverage containers in vehicles under La. R.S. 32:300. An open container at the scene can support the inference that the driver had been drinking. It is part of the evidence picture, not a standalone liability theory.

One critical distinction: a criminal conviction does not automatically create civil liability. In your civil case, you must independently prove that the driver's intoxication caused the crash and your injuries. The conviction is powerful evidence. It is not a shortcut to a verdict.

Ask any attorney you are considering: have they litigated a case where the drunk driver was not convicted or the criminal case was still pending? How did they establish intoxication in the civil proceeding? A competent attorney has a strategy for proving impairment that does not depend on the criminal outcome.

How Alcohol Impairs Drivers -- What the Evidence Shows

Alcohol impairs driving before it reaches the legal limit. That fact matters in your case because it establishes the driver was impaired even if their BAC reading was below 0.08, or if testing was delayed.

At 0.02 BAC, divided attention degrades and visual tracking of moving objects becomes less accurate. At 0.05 BAC, coordination declines measurably. Emergency steering response slows. At 0.08 BAC, the legal limit, speed perception, judgment under pressure, and concentration all impair significantly. At 0.10 and above, lane control breaks down. Braking reaction time lengthens. Hazard recognition deteriorates.

Chemical test results (blood, breath, or urine) are admissible in civil cases under the same evidentiary rules that apply in criminal proceedings. A driver's refusal to submit to chemical testing is also admissible. Louisiana courts allow juries to draw an adverse inference from a refusal. The driver's decision to decline testing can be used against them.

Toxicology reports from emergency room treatment are routinely obtained in drunk driving cases. When blood is drawn at the hospital, the chain of custody for that sample matters. An experienced attorney will verify that the sample was properly labeled, stored, and analyzed. Field sobriety test results from the crash scene appear in the police report and are discoverable in civil litigation.

When evaluating attorneys, ask: have they worked with a toxicology expert before? What is the standard for challenging a BAC result in civil court? At Morris & Dewett, we retain toxicology consultants on cases where BAC readings are borderline or where the defense is contesting the testing methodology.

What to Do Immediately After a Drunk Driving Crash in Louisiana

The steps you take in the first hours after a crash affect your ability to recover damages. Here is what to prioritize.

Call 911 immediately. Request police and EMS. Do not move injured people unless there is an immediate physical hazard. When officers arrive, get the responding officer's name and badge number. Ask the investigating officer whether the other driver was arrested, cited, or tested for alcohol. You are entitled to this information. Write it down.

At the scene, photograph everything you can safely access. Vehicle damage from multiple angles. Skid marks. Road conditions. Traffic signal positions. The position of each vehicle after impact. These photographs become part of the evidence record. They cannot be recreated.

Once you leave the scene, report to an emergency room or urgent care even if injuries are not obvious. Some injuries, including traumatic brain injury and internal bleeding, do not produce immediate symptoms. A medical record from the same day as the crash establishes the timeline. A gap between the crash and your first medical visit gives insurance adjusters a basis to argue the injuries were pre-existing or unrelated.

Preservation demand letters must go out quickly. Bar surveillance video, dashcam footage from nearby vehicles, and traffic camera recordings can be overwritten within 24 to 72 hours. Receipts from bars and restaurants visited by the driver before the crash, credit card records, and cell phone location data are all discoverable and help establish when and how much the driver was drinking.

Witnesses who saw the driver at a bar before the crash are particularly valuable. If you have names or contact information for anyone at the scene, preserve them. Your attorney's team will conduct follow-up interviews.

Social media posts from the driver before the crash are admissible evidence. Posts showing alcohol consumption, location check-ins at bars, or statements about drinking that evening are routinely obtained through litigation discovery. Do not assume this evidence disappears.

Who Can Be Held Liable in a Louisiana Drunk Driving Case

The drunk driver is the primary defendant. Liability against the driver is established through the police report, BAC test results, arrest records, field sobriety test documentation, and witness testimony. A criminal conviction, if one results, is admissible.

Vehicle owner liability arises when the driver was operating someone else's vehicle. If the owner knew the driver was incompetent, unlicensed, intoxicated, or otherwise unfit to drive and gave them access anyway, the owner may be liable under the doctrine of negligent entrustment. This theory applies to both private individuals and commercial fleet owners.

Employer liability attaches when the driver was on-duty or driving a company vehicle. Under the doctrine of respondeat superior, employers are responsible for employee negligence that occurs within the scope of employment. If a sales representative was driving home from a client visit and caused the crash, the employer may share liability.

Dram shop liability is more limited in Louisiana than in most states. La. R.S. 9:2800.1 provides that sellers and social hosts are generally not liable for injuries caused by intoxicated patrons. The exception is narrow: a vendor who served a visibly intoxicated person or served alcohol to a minor may face civil liability. Proving visible intoxication at the time of service requires witness testimony from bar staff, surveillance video, or other patrons present.

One important exception under La. R.S. 9:2800.1(B): a vendor who sold or served alcohol to a minor (a person under 21) can be held civilly liable regardless of whether the minor appeared intoxicated at the time of sale.

If your crash occurred near the Louisiana-Texas border, or if the driver was served at a Texas establishment, Texas law may apply to the dram shop claim. Texas takes a substantially different approach. The Texas Dram Shop Act (Tex. Alco. Bev. Code Sec. 2.02) imposes civil liability on establishments that overserved a patron who then caused injury. The Texas standard is more favorable to plaintiffs than Louisiana's.

Ask any attorney you speak with: have they brought a dram shop claim in Louisiana? How did they establish that the vendor served a visibly intoxicated patron? What evidence types were most effective? This is a specialized area with a narrow window for success. Not every attorney has litigated these claims.

Louisiana Comparative Fault and Drunk Driving Cases

Louisiana's comparative fault rule is set by La. C.C. Art. 2323, which took effect January 1, 2026. Under the current rule, if you are found 51% or more at fault for the crash, you recover nothing. If your fault is 50% or less, your damages are reduced by your percentage of fault.

This rule matters in drunk driving cases because insurance adjusters frequently try to shift fault onto the injured person. Common arguments include: you were speeding, you ran a red light, you had an obstructed view, or you failed to take evasive action. Each of these, if credited by a jury, reduces your recovery. If they push your fault above 50%, you lose entirely.

The 51% bar creates real exposure. A careful accident reconstruction preserves your fault percentage. This means retaining a qualified accident reconstructionist early, before physical evidence at the scene disappears. Morris & Dewett works with accident reconstructionists and biomechanical engineers to establish what happened before the insurance company builds its own narrative.

Louisiana does not allow punitive damages in most civil cases. Drunk driving cases are one of the few exceptions. La. C.C. Art. 2315.4 provides for Exemplary Damages when death or injury is caused by a defendant whose intoxication was a cause-in-fact of the harm. The court may award up to three times the amount of general damages.

Exemplary damages under Art. 2315.4 must be specifically pled in the petition. They are not automatic. They are contested by defense counsel and insurance companies because they can dramatically increase a verdict. Your attorney must be prepared to present specific evidence of intoxication as a causation element, not just background context.

Prescriptive Period and Filing Deadlines

Two years. That is the deadline to file a personal injury lawsuit in Louisiana after a drunk driving crash. The deadline is set by La. C.C. Art. 3493.11, which took effect July 1, 2024. Missing this deadline almost always results in permanent loss of your right to recover.

Prescriptive Period The two-year clock starts from the date of the accident, not the date your treatment ends or the date the criminal case concludes.

Wrongful death claims follow the same two-year period, measured from the date of death under La. C.C. Arts. 2315.1 and 2315.2. A survival action, which recovers damages for the victim's own suffering before death, follows the same deadline.

The criminal case does not toll the civil prescriptive period. Even if the drunk driver is under criminal prosecution, your civil deadline continues to run. Many people wait for the criminal case to conclude before consulting a civil attorney. That is a mistake that can cost you the right to recover.

The discovery rule applies in limited circumstances: if injuries were not apparent at the time of the crash, the prescriptive period may begin from the date you learned or should have learned about them. This is narrow and fact-specific. Do not assume it applies to your case without talking to an attorney.

If the crash occurred during your employment, separate deadlines apply. La. R.S. 23:1101 governs the employer's right to recover workers' compensation payments from third parties, and La. R.S. 23:1209 sets the prescriptive period for those subrogation claims. These run concurrently with your personal injury claim, not separately.

Contact Morris & Dewett to get a case evaluation before the deadline approaches.

What Injuries Are Common in Louisiana Drunk Driving Crashes?

Drunk driving crashes tend to be severe. The driver's impaired judgment leads to high-speed intersection collisions, wrong-way driving, and failure to brake. The physics of these impacts produce injuries that are disproportionately serious compared to other collision types.

TBI Head-on collisions, which drunk drivers cause at elevated rates, produce severe head trauma. TBI symptoms may not appear immediately. Delayed diagnoses are common. If you experienced a loss of consciousness, disorientation, or persistent headaches after the crash, a neurological evaluation is necessary.

Spinal cord injuries result from the forces generated in high-speed impacts. Cervical injuries to the neck and lumbar injuries to the lower back can produce permanent limitations in mobility and sensation. Surgical intervention, rehabilitation, and long-term care needs are quantified by medical experts and life care planners in litigation.

Side-impact crashes, common in intersection drunk driving collisions, cause broken bones, internal organ damage, and facial trauma. These injuries are typically visible in emergency room imaging and well-documented.

Soft tissue injuries, including whiplash and muscle tears, may not appear immediately. They develop over the 24-48 hours following the crash as inflammation sets in. These injuries are documented through MRI, specialist evaluation, and physical therapy records. Insurance adjusters routinely challenge soft tissue claims. Contemporaneous documentation from the first days after the crash is critical.

In high-impact crashes involving fuel system rupture, fire-related burn injuries occur. These cases involve additional defendants and product liability theories if the vehicle's fuel system failed outside expected performance parameters.

What Compensation Is Available in a Louisiana Drunk Driving Case

Louisiana drunk driving victims can recover economic damages, non-economic damages, and in some cases exemplary damages up to three times general damages. Economic damages cover financial losses that can be calculated. Medical expenses include emergency care, hospitalization, surgery, rehabilitation, physical therapy, medication, and projected future treatment. Lost wages account for income you could not earn while recovering. Loss of Earning Capacity is a separate category calculated by vocational rehabilitation specialists and economic experts. Vehicle repair or replacement and other out-of-pocket costs are also recoverable.

Non-economic damages compensate for losses that do not have a price tag. Pain and suffering. Emotional distress. Disfigurement. Loss of enjoyment of life. Loss of Consortium for a spouse. These damages are established through your testimony, the testimony of family members, and medical documentation of the effect on your daily life.

Exemplary damages under La. C.C. Art. 2315.4 are available only in intoxication cases. The court may award up to three times the general damages if the jury finds that the defendant's intoxication caused the injury or death. They must be specifically requested in your petition. Not every drunk driving case qualifies. The specific facts of the defendant's intoxication must be proven as a causation element.

If the drunk driver was uninsured or underinsured, your own auto policy's UM/UIM coverage becomes the primary source of recovery under La. R.S. 22:1295. Louisiana requires insurers to offer UM/UIM coverage. If you declined it, that rejection had to be made in writing. An attorney can verify whether a proper waiver exists.

Proving damages requires expert witnesses. Medical professionals testify to future care needs and the permanence of injuries. Vocational rehabilitation experts calculate earning capacity loss. Life care planners produce detailed projections of long-term costs. Morris & Dewett works with a network of qualified experts on these cases.

Louisiana Drunk Driving Statistics

In 2023, alcohol-related traffic fatalities in Louisiana totaled 244, with impaired driving involved in 30.1% of all motor vehicle crash fatalities statewide, according to the Louisiana Highway Safety Commission. Louisiana's rate is consistent with the national pattern: roughly 1 in 3 traffic fatalities nationally involve an alcohol-impaired driver (NHTSA data).

By 2024, Louisiana's drunk driving fatality count dropped to 161, an 18.3% decrease from 2023. That improvement reflects enforcement and education efforts. It does not eliminate the risk. Drunk driving remains a leading cause of fatal crashes on Louisiana roads.

East Baton Rouge Parish had the most fatal drunk driving accidents of any parish in the state. Concentrated population centers along interstate corridors, including I-10 and I-12, account for a disproportionate share of alcohol-involved crashes in the southern part of the state. Rural parish roads present a different risk: lower traffic density means less chance of early detection, and crashes on rural roads often involve higher speeds.

Weekend nights between midnight and 3 a.m. account for a disproportionate share of drunk driving crashes. This pattern appears consistently in federal crash data. Nighttime crashes tend to produce more severe injuries because speeds are higher and traffic is lighter, meaning impaired drivers travel farther before encountering an obstacle or another vehicle.

Frequently Asked Questions

What is the difference between a DWI and DUI in Louisiana?

In Louisiana, the statutory offense is DWI: Driving While Intoxicated under La. R.S. 14:98. Louisiana does not have a separate "DUI" statute. The term DUI is used informally and is treated as interchangeable. You may also see OWI (Operating While Intoxicated) or OUI in older filings or informal usage. All refer to the same offense under La. R.S. 14:98. For civil purposes, the label does not matter. What matters is whether the driver was impaired and whether that impairment caused the crash.

Can I sue the bar or restaurant that served the drunk driver in Louisiana?

Dram shop claims in Louisiana are possible but difficult. La. R.S. 9:2800.1 limits vendor liability. A bar or restaurant is generally not liable for injuries caused by a patron they served unless they served a visibly intoxicated person or served alcohol to a minor under 21. Proving visible intoxication requires evidence of what the patron looked and acted like at the time of service, typically established through surveillance video, staff testimony, or witness accounts from other patrons. The standard is narrow. If the driver was served at a Texas establishment before crossing into Louisiana, Texas's broader Dram Shop Act may apply instead.

Does a criminal DWI conviction help my civil case?

Yes, substantially. A criminal conviction for DWI is admissible in your civil proceeding and establishes that the driver was legally impaired at the time of the crash. It cannot be relitigated. However, a conviction is not required for civil liability. If the driver was not charged, pled to a lesser offense, or the criminal case is still pending, your civil case proceeds independently. Morris & Dewett regularly handles civil claims where the drunk driver avoided criminal conviction. The standard of proof in civil cases is preponderance of the evidence, not beyond a reasonable doubt, which is a lower threshold.

How long do I have to file a lawsuit after a drunk driving accident in Louisiana?

Two years from the date of the accident under [La. C.C. Art. 3493.11](https://legis.la.gov/legis/Law.aspx?d=1092220), effective July 1, 2024. For wrongful death claims, the two-year period runs from the date of death under [La. C.C. Arts. 2315.1](https://legis.la.gov/legis/Law.aspx?d=109385) and [2315.2](https://legis.la.gov/legis/Law.aspx?d=109386). The criminal case does not pause this clock. Missing the prescriptive period almost always means losing your right to recover permanently.

What are exemplary damages in a Louisiana drunk driving case?

Exemplary damages are a special category authorized by La. C.C. Art. 2315.4 for intoxication cases. If a jury finds that the defendant's intoxication was a cause-in-fact of the injury or death, the court may award up to three times the general damages the jury awarded. They must be specifically pled in the petition. They are not available in every drunk driving case. They require proof that intoxication was a causation factor, not merely background context. Defense counsel and insurers typically contest them aggressively because of their potential to multiply the verdict.

What if the drunk driver had no insurance?

Your own auto policy is the first place to look. [La. R.S. 22:1295](https://legis.la.gov/legis/Law.aspx?d=508161) requires insurers to offer uninsured motorist (UM) and underinsured motorist (UIM) coverage with every Louisiana auto policy. If you declined that coverage, the rejection had to be in writing on a form that meets statutory requirements. An attorney can verify whether the waiver was valid. If the waiver was not properly executed, you may still have UM/UIM coverage available. If the drunk driver had some insurance but not enough to cover your damages, your UIM coverage applies to the gap.

Can I recover damages if I was partially at fault in the crash?

Yes, as long as your fault percentage is 50% or below. Under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109376), effective January 1, 2026, Louisiana applies a modified comparative fault rule with a 51% bar. If you are found 51% or more at fault, you recover nothing. If you are 50% or less at fault, your damages are reduced proportionally. For example, if a jury finds you 20% at fault and awards $100,000 in damages, you recover $80,000. Insurance adjusters work to push your fault percentage as high as possible. A thorough accident reconstruction conducted early preserves your fault percentage before the physical evidence disappears.

What should I do immediately after being hit by a drunk driver?

Call 911. Get police and EMS to the scene. Do not move injured people unless there is an immediate hazard. Get the responding officer's name and badge number, and ask whether the other driver was arrested or tested. Photograph vehicle damage, road conditions, skid marks, and traffic signal positions. Seek medical evaluation the same day, even if you do not feel injured. Contact an attorney as soon as possible. Surveillance video and dashcam footage from nearby vehicles can be overwritten within 24 to 72 hours.

What happens if the drunk driver leaves the scene?

A hit-and-run by a drunk driver does not eliminate your right to recover. Report the crash to police immediately and preserve any evidence you have of the other vehicle: color, make, model, partial plate, direction of travel. Your own uninsured motorist (UM) coverage under [La. R.S. 22:1295](https://legis.la.gov/legis/Law.aspx?d=508161) covers hit-and-run accidents where the other driver is unidentified. Louisiana law requires physical contact with the unidentified vehicle for UM coverage to apply in most cases. Document the physical damage to your vehicle carefully.

How long does it take to resolve a drunk driving accident case in Louisiana?

It varies significantly based on the severity of injuries, the number of defendants, whether liability is disputed, and whether the case settles or goes to trial. Cases with clear liability and documented injuries frequently resolve within 12 to 24 months. Complex cases involving severe injuries, disputed fault, dram shop defendants, or exemplary damages claims can take three to five years if they proceed to trial. Reaching {TERM: MMI | Maximum Medical Improvement. The point at which your treating physician determines your condition has stabilized and further treatment will not significantly change the outcome.} before settling is generally advisable because it establishes the full extent of your damages. Settling before MMI risks leaving future medical costs unaccounted for.

These answers reflect Louisiana law as of January 2026. For case specific advice, consult with a Louisiana personal injury attorney who can evaluate your particular circumstances.
