Can You Drink and Drive in Louisiana? Daiquiri Rule and Penalties

Drinking and driving in Louisiana is governed by a simple threshold with an unusual wrapper: you can legally buy a sealed frozen daiquiri at a drive-through and carry it in your car, but operating a vehicle with a blood alcohol concentration of 0.08% or higher, or while impaired by any substance, is a crime. The gap between what Louisiana allows you to possess and what it allows you to do behind the wheel is narrower than the state’s reputation suggests, and the penalties for crossing it start steep and climb quickly.

The Open Container Rule and the Daiquiri Exception

Drivers and passengers in Louisiana cannot possess an open alcoholic beverage container or drink alcohol in the passenger area of a moving vehicle on a public road. A violation carries a fine of up to $100.¹

The carve-out that makes Louisiana famous: a frozen alcoholic drink is not an “open container” as long as the lid stays on, no straw pokes through the top, and none of the contents have been removed.¹ Peel the tape, insert the straw, and it becomes an open container. Containers in the trunk or a locked glove compartment also fall outside the rule.

None of this changes the DWI analysis. Carrying a sealed drink is legal; being impaired while driving is not, regardless of where the alcohol came from.

BAC Limits by Driver Type

Louisiana sets three thresholds depending on who is driving:

Adults 21 and older: 0.08% by weight.²
Commercial drivers: 0.04% while operating a commercial vehicle, with the violation reported to the FMCSA Drug and Alcohol Clearinghouse.³
Drivers under 21: 0.02%, effectively zero tolerance, with a license suspension triggered by the implied consent statute at that level.⁴

Reading under those numbers does not guarantee you’re safe from arrest. Louisiana can charge DWI at any BAC if your driving is impaired.

What Counts as Impaired Driving

Louisiana’s statute uses the phrase “operating a vehicle while impaired,” and it reaches further than alcohol. You can be charged if a controlled substance, a prescription drug, or an over-the-counter medication affects your ability to drive safely.² The law also applies to boats, aircraft, and other motorized conveyances, not just cars.

Police do not need a BAC above 0.08% to arrest you. Erratic driving, failed field sobriety tests, or other signs of impairment can support a charge on their own. A BAC of 0.08% or higher creates a legal presumption of impairment, but it is not the only route to a conviction.

First-Offense Penalties

A first DWI conviction carries a fine between $300 and $1,000 and jail time from 10 days to six months.⁵ Most of the jail time can be suspended on probation, but at least 48 hours cannot. A judge can substitute at least 32 hours of community service, half of it litter cleanup, in place of those 48 hours.

Probation typically requires a substance abuse program, which may include a clinical assessment for substance use disorder, and a driver improvement program.⁵ The court may also order an ignition interlock device.

Higher readings add penalties on top. A BAC between 0.15% and 0.20% adds another 48 hours of mandatory, non-suspendable jail time. At 0.20% or above, the minimum fine rises to $750 and additional mandatory jail time applies.⁵

Repeat Offenses

Prior DWI convictions count regardless of their order relative to each other, so there’s no timing trick that erases them.

Second Offense

A second conviction carries a fine of $750 to $1,000 and 30 days to six months in jail, with at least 48 hours that cannot be suspended.⁶ If the second arrest comes within a year of the first offense, the mandatory minimum jumps to 30 days. An ignition interlock device becomes mandatory for at least six months.⁷ A BAC of 0.20% or higher triggers a four-year license suspension with the interlock required for the first three years.

Third Offense

A third DWI brings a $2,000 fine and one to five years in prison, with or without hard labor. At least one full year is mandatory and cannot be suspended. The court can order your vehicle seized, impounded, and sold at auction.

Fourth and Subsequent Offenses

A fourth DWI is sentenced under a separate provision carrying the most severe penalties Louisiana imposes for impaired driving, with state prison time measured in years rather than parish jail time measured in months.²

Having a Child in the Car

If a child 12 or younger is in the vehicle, Louisiana’s Child Endangerment Law removes the court’s authority to suspend any mandatory minimum sentence.² It applies at every offense level. On a first offense, the 48 hours a judge might otherwise convert to community service must be served in jail. On a third offense, the full one-year minimum must be served. There is no separate charge; the safety valve that keeps many offenders out of jail simply disappears.

License Suspension

Louisiana imposes two separate kinds of suspension after a DWI, and they can stack.

Administrative Suspension

This happens immediately after arrest, before any conviction. A BAC of 0.08% or above on a chemical test triggers a 180-day suspension for a first offense; a second or subsequent offense within five years is 365 days.⁸ At 0.15% or above, the administrative suspension is two years for a first offense and four years for a second.

Court-Ordered Suspension

A first conviction brings an additional 12-month suspension. A first conviction with a BAC of 0.15% or higher brings 24 months, though a restricted license is available with an ignition interlock. Second convictions carry 24 months; third and subsequent convictions, 36 months.⁹

The practical result: your license can be taken at the roadside, and you may be without it for months even if your criminal case drags on.

Implied Consent and Refusing the Test

By driving on Louisiana roads, you’ve already consented to chemical testing of blood, breath, or urine when an officer arrests you for DWI.⁴ Before the test, the officer must read a standardized form explaining your rights and the consequences of refusing.

A first refusal brings a one-year license suspension, separate from any DWI-related suspension, and it stands even if you’re never convicted.⁸ Prosecutors can use the refusal against you at trial. A third refusal, with two prior refusals on record, is itself a crime carrying the same penalties as a first-offense DWI.⁴

One constitutional line matters here. The U.S. Supreme Court held in Birchfield v. North Dakota that police can require a breath test without a warrant on a lawful DWI arrest, but a blood test needs a warrant or genuine consent, and states cannot criminally punish someone solely for refusing a warrantless blood draw.¹⁰

Ignition Interlock Devices

An interlock prevents your car from starting unless you blow a breath sample below 0.02%. It’s discretionary on a first offense and mandatory on a second.⁷ Louisiana offers credit toward your suspension period if you install one voluntarily, but you lose that credit if you tamper with the device, miss required service appointments, or fail three or more recorded breath tests in a 30-day window.

Costs typically run $500 to $1,600 for the full term, including installation and monthly monitoring. The device must be serviced by an approved provider every 30 days.

Insurance and SR-22

Anyone convicted of a DWI or who refuses a chemical test must file an SR-22 certificate of financial responsibility with the Office of Motor Vehicles and maintain it for three years. The SR-22 filing itself is cheap, typically $15 to $50, but insurers treat DWI as one of the highest risk factors, and premium increases of 100% or more are common. Some drivers end up with specialty high-risk insurers.

Traveling to Canada After a DWI

Canada treats impaired driving as a serious criminal offense punishable by up to 10 years of imprisonment, which can make a U.S. citizen with a DWI inadmissible at the border.¹¹ Canadian law bars a foreign national convicted of an offense that would be indictable in Canada, and since Canada reclassified impaired driving as a hybrid offense with a 10-year maximum in 2018, even a single U.S. misdemeanor DWI can trigger the bar.

Workarounds exist. A Temporary Resident Permit can cover short visits, and Criminal Rehabilitation becomes available once all sentencing and probation have been complete for at least five years. A single old conviction more than 10 years back may qualify for “deemed rehabilitation” at the border, but that call is discretionary.

DWI on Federal Property in Louisiana

Impaired driving on a military installation, national wildlife refuge, or other federal property in Louisiana is prosecuted in federal court, not state court. A conviction is a Class B federal misdemeanor with up to six months of imprisonment, a fine of up to $5,000, and up to five years of probation. A U.S. Magistrate Judge decides the case; there is no jury trial. When federal regulations don’t cover a specific situation, federal courts can apply Louisiana’s DWI penalties through the Assimilative Crimes Act, which can produce punishment matching or exceeding what state court would impose.
