What Are the Consequences of Refusing an OWI/DUI Breathalyzer Test in Indiana?

Understanding Criminal Penalties and Your Defense Options

A refusal after an OWI stop can create problems before your criminal case even begins. You may be facing a license suspension, a criminal investigation, and a state that will look for other evidence to build its case against you. 

Refusing a Breathalyzer or other chemical test can create serious legal consequences, including the possible suspension of your driving privileges. However, a refusal does not automatically prevent an OWI charge, and it does not guarantee that prosecutors cannot build a case against you.

Indiana’s implied consent law requires drivers who operate vehicles in the state to submit to chemical testing when law enforcement officers have probable cause to believe they were operating while intoxicated. When a driver refuses, that refusal may lead to administrative penalties from the Indiana Bureau of Motor Vehicles (BMV) and may also serve as evidence for prosecutors in the criminal case.

At Summerfield-Dandurand Law Group, LLP, Founders of Custom Law, we help people throughout Indiana understand the consequences of an OWI arrest, including license suspension issues, refusal allegations, and potential defense strategies. Understanding your rights early can help you make informed decisions about your case.

Indiana’s Implied Consent Law and OWI Chemical Testing Requirements

Indiana’s implied consent law gives law enforcement a process for requesting chemical testing during an OWI investigation. But the existence of that law does not mean every refusal automatically leads to a valid penalty. 

Chemical tests may include:

• Breath tests administered through an approved testing device.
• Blood tests.
• Urine tests.

These tests are different from field sobriety tests. Field sobriety exercises generally involve physical observations, such as balance or coordination assessments, and refusing those exercises does not trigger the same implied consent penalties as refusing a chemical test.

A chemical test refusal becomes legally significant because Indiana law attaches consequences to a driver’s decision not to provide a sample after being properly requested to do so.

However, police officers must still follow legal procedures. Issues such as whether the officer had probable cause, whether proper warnings were provided, and whether testing requirements were followed may become important issues in an OWI defense.

What Happens If You Refuse a Breathalyzer in Indiana?

A refusal does not end the investigation. Officers and prosecutors may rely on other evidence, and they may attempt to use the refusal itself against you. The question becomes whether the State followed the law and whether the evidence actually supports the charge. 

The consequences generally fall into two categories:

1. Administrative consequences involving your driver’s license.
2. Criminal consequences related to the OWI charge.

Both should be taken seriously.

Your Driver’s License May Be Suspended After an OWI Test Refusal

The first battle after a refusal may involve your driver’s license. The BMV can pursue a suspension separately from your criminal case, creating consequences before a judge ever decides the OWI charge. 

Under Indiana’s implied consent laws, refusing a chemical test may result in a driver’s license suspension through the BMV process.

A suspension may apply even if your criminal OWI case has not yet been resolved.

For many people, this creates immediate problems, including:

• Difficulty getting to work.
• Transportation challenges for family responsibilities.
• Problems attending school or medical appointments.

The length of suspension depends on the circumstances of the case, including whether the driver has a previous OWI-related history.

Because a BMV suspension and a criminal OWI charge are separate matters, a person may need to address both proceedings.

Administrative License Suspension Is Separate From the Criminal OWI Case

Some drivers assume that if they successfully defend their OWI charge, their license will automatically be reinstated. That is not always the case.

The Indiana BMV handles administrative license suspensions separately from criminal court proceedings.

This means:

• You may face a license suspension because of the refusal itself.
• Your criminal OWI case may continue separately.
• Winning one matter does not always automatically resolve the other.

A suspension is not something to ignore. Strict deadlines may apply, and the circumstances of the stop, warning, and refusal may matter when challenging the suspension. 

An Indiana OWI attorney can review whether the officer complied with implied consent requirements and whether there are grounds to challenge the suspension.

Can You Still Be Charged With OWI If You Refuse a Breathalyzer?

Yes. Refusing a Breathalyzer does not prevent prosecutors from filing an OWI charge.

Under Indiana Code § 9-30-5, a person may be charged with operating while intoxicated if the state can prove the required elements of the offense.

A Breathalyzer result is only one possible piece of evidence.

Prosecutors may rely on other evidence, including:

• The officer’s observations of your behavior.
• The smell of alcohol or signs of impairment.
• Statements made during the traffic stop.
• Driving patterns before the stop.
• Results of field sobriety exercises.
• Dash camera or body camera footage.
• Testimony from officers or witnesses.

The prosecution must still prove the case beyond a reasonable doubt. A refusal is only one piece of evidence; it is not proof by itself. 

How Does Refusing a Breathalyzer Affect Your OWI Defense?

Whether refusing a Breathalyzer helps or hurts depends on the facts of the case. There is no shortcut answer. The details matter, such as what the officer did, what warnings were given, what evidence exists, and whether your rights were respected. 

Some drivers believe refusing prevents the state from proving intoxication because there is no BAC number. While the lack of a chemical result may create challenges for prosecutors, the state may still attempt to prove impairment through other evidence.

Additionally, prosecutors may argue that a refusal demonstrates awareness that alcohol or drugs may have affected the driver’s ability to operate safely.

However, a refusal alone is not proof that a person was intoxicated.

A defense attorney may examine:

• Whether the police had lawful grounds to request testing.
• Whether proper implied consent warnings were provided.
• Whether the refusal was actually voluntary.
• Whether other evidence supports the OWI allegation.
• Whether constitutional rights were violated during the investigation.

Can Police Use a Breathalyzer Refusal Against You in Court?

Yes, prosecutors may attempt to introduce evidence of a refusal in an OWI case.

Indiana courts recognize that refusal evidence may be relevant because it may provide information about a defendant’s conduct after an OWI investigation begins.

However, prosecutors still must prove every element of the offense.

A refusal does not eliminate the need for the state to establish that:

• You operated the vehicle.
• You were intoxicated under Indiana law.
• The evidence supports the specific charge filed.

The defense may challenge how the refusal occurred and whether the state can properly use that evidence.

What Should You Do After Refusing an OWI Chemical Test?

After refusing a Breathalyzer or other chemical test, it is important to take immediate steps to protect your rights.

Do Not Assume the Case Is Over

A refusal does not mean the OWI charge disappears. Prosecutors may continue with the case using other evidence.

Avoid Discussing the Case With Others

Statements made after an arrest may later become relevant. Discussing the facts publicly or on social media can create additional problems.

Review Your License Suspension Immediately

Because BMV matters can move quickly, you should understand whether a suspension has been initiated and what options may exist.
