What Happens If You Refuse a Breathalyzer in Louisiana?

You just got pulled over. The officer smells alcohol and asks you to take a breathalyzer test.

Should you refuse?

In Louisiana, refusing a breathalyzer triggers an automatic license suspension under the state’s implied consent law—even before any DUI conviction. The suspension starts immediately, and you have only 30 days to request a hearing to challenge it.

This isn’t about whether you’re guilty or innocent. The moment you refuse, Louisiana law treats it as a separate offense with its own penalties that stack on top of any DUI charges.

Here’s what actually happens when you say no to that breathalyzer.

Louisiana’s Implied Consent Law Explained

Louisiana Revised Statute 32:661 establishes what’s called “implied consent.” This means that by simply driving on Louisiana roads, you’ve already agreed to submit to chemical testing if an officer has reasonable grounds to believe you’re impaired.

You didn’t sign anything. You didn’t explicitly agree. But under Louisiana law, your driver’s license itself represents that agreement.

When you refuse testing, you’re violating this implied consent—and the consequences are immediate and severe.

The law applies to breath, blood, and urine tests. If an officer lawfully requests any of these tests and you refuse, the penalties kick in automatically.

Immediate Consequences of Refusing a Breathalyzer

The officer will confiscate your license on the spot. You’ll receive a temporary driving permit that’s only valid for 30 days. After those 30 days, your driving privileges are suspended—period.

First refusal penalties:

• License suspension for 365 days minimum
• No hardship license available for the first 180 days
• Required installation of an ignition interlock device once you can drive again
• Refusal used as evidence against you in court

Second or subsequent refusal:

• License suspension for 2 years
• No hardship license for the first 12 months
• Mandatory ignition interlock device
• Enhanced penalties if convicted of DUI

The suspension happens through the Louisiana Office of Motor Vehicles, completely separate from any criminal DUI case. You’re fighting on two fronts: the administrative suspension and the criminal charges.

Can Refusing Help Your DUI Case?

Many people refuse the breathalyzer thinking it will help their case. The logic seems sound—no test results means no evidence of intoxication, right?

Wrong.

Louisiana courts allow prosecutors to tell the jury you refused the test. Under RS 32:662, your refusal can be used as evidence of consciousness of guilt. The prosecutor will argue that you refused because you knew you were drunk.

The officer will still testify about:

• How you were driving
• The smell of alcohol
• Your slurred speech or bloodshot eyes
• How you performed on field sobriety tests
• Your behavior and statements

Without the breathalyzer, they build the case on observation. And they’ll make sure the jury knows you refused to cooperate.

Meanwhile, you’re still facing that automatic license suspension.

The 30-Day Window to Fight Your Suspension

You have exactly 30 days from the date of your arrest to request an administrative hearing with the Office of Motor Vehicles. Miss this deadline and your suspension becomes final—no exceptions, no extensions.

This hearing is separate from your criminal DUI case. At the administrative hearing, the issues are limited:

• Did the officer have reasonable grounds to stop you?
• Did the officer have reasonable grounds to believe you were impaired?
• Were you properly advised of the consequences of refusing?
• Did you actually refuse the test?

The burden of proof is lower than in criminal court. The OMV only needs to show these facts by a preponderance of the evidence—meaning it’s more likely than not.

If you lose this hearing, your suspension stands. If you win, your license is restored, but you still face the criminal DUI charges in court.

Chemical Testing After Refusing

Some people think refusing means they’ll never be tested. That’s not always true.

If the officer has a warrant or if certain circumstances exist—such as an accident involving serious injury or death—Louisiana law allows forced blood draws under RS 32:661. This typically happens when you’re transported to a hospital after an accident.

According to the National Highway Traffic Safety Administration, law enforcement can obtain search warrants for blood draws, especially in serious crashes. Louisiana courts regularly uphold these warrants.

You can refuse the breathalyzer, but you may still end up with test results entered as evidence—plus the refusal penalties on top of everything else.

How Refusal Affects CDL Holders

Commercial driver’s license holders face even harsher consequences.

Under Louisiana law, CDL holders are subject to stricter standards. If you refuse a chemical test while driving any vehicle—even your personal car—you face:

• One-year CDL disqualification for first refusal
• Lifetime disqualification for second refusal
• Federal regulations make these penalties non-negotiable

The Federal Motor Carrier Safety Administration sets minimum disqualification standards that states must follow. Louisiana can’t offer you a hardship license for commercial driving.

This can destroy your livelihood. One refusal, one bad decision, and you’re out of the trucking industry permanently on a second offense.

What About the Blood Alcohol Evidence?

Here’s what many people don’t realize: even without a breath test, prosecutors can still prove intoxication.

Louisiana recognizes DUI based on impairment, not just BAC levels. Under RS 14:98, you can be convicted if you’re “under the influence of alcoholic beverages” regardless of your blood alcohol concentration.

Evidence used to prove impairment includes:

• The officer’s observations and testimony
• Field sobriety test results
• Statements you made
• Dashcam or body camera footage
• Witness testimony

The Centers for Disease Control and Prevention reports that impaired driving behaviors are observable even at BAC levels below the legal limit. Prosecutors know how to make these cases without a breathalyzer.

Getting Your License Back After Refusal

Once the suspension period begins, getting your license back requires several steps:

You must serve the mandatory suspension period—180 days minimum before you can even apply for a hardship license on a first refusal. During this time, you cannot legally drive except in extremely limited circumstances.

After the mandatory period, you’ll need to:

• Pay a reinstatement fee to the OMV
• Provide proof of insurance (SR-22)
• Install an ignition interlock device
• Complete substance abuse evaluation if required
• Pay all outstanding fines and fees

The ignition interlock device costs $100-150 for installation, plus $75-100 monthly monitoring fees. You’ll have this device for the duration of your restricted driving period.

Challenging the Refusal Suspension

An experienced traffic attorney can challenge your suspension at the administrative hearing. Successful challenges focus on:

• Lack of reasonable suspicion for the traffic stop
• Improper administration of implied consent warnings
• Officer error in procedures or paperwork
• Constitutional violations during the stop

If your attorney can show the officer lacked reasonable grounds to request the test, or failed to properly advise you of the consequences, the suspension can be overturned.

Time is critical. Evidence disappears, witnesses forget details, and video footage can be overwritten. The sooner you have an attorney working on your case, the better your chances.

Should You Ever Refuse a Breathalyzer?

There’s no simple answer. Every situation is different.

If you’re certain you’re over the legal limit, refusing might seem like it helps. But the automatic suspension, the use of your refusal against you in court, and the potential for a warrant-backed blood draw mean you’re not necessarily better off.

If you’ve had one drink and believe you’re under the limit, taking the test might be your better option. A low BAC reading can actually help your defense.

The real answer is that you need to understand Louisiana’s implied consent law before you’re ever in this situation. Once you’re on the side of the road being asked to blow into a breathalyzer, your options are limited and the consequences are severe no matter what you choose.

Protect Your License and Your Future

A breathalyzer refusal creates immediate consequences that don’t wait for a conviction. Your license is suspended, your ability to drive is gone, and you’re facing enhanced penalties if you’re ultimately convicted of DUI.
