Indiana Implied Consent Laws Explained: Refusing a Breathalyzer or Blood Test

When you are pulled over on suspicion of Operating While Intoxicated (OWI) in Indiana, you may feel that your best defense is simply to refuse all testing. Many drivers believe that if the police have no scientific proof of their blood alcohol concentration (BAC), they cannot be convicted. Unfortunately, Indiana law anticipates this strategy. By choosing to operate a vehicle on state roads, you have already legally agreed to submit to chemical testing if an officer has probable cause to suspect you are driving under the influence.

This legal principle is known as 'Implied Consent.' Violating this law triggers severe administrative penalties from the Indiana Bureau of Motor Vehicles, Indianapolis that are entirely separate from your criminal court case. If you have been arrested and accused of a refusal in cities like South Bend, Carmel, or Lafayette, securing a knowledgeable OWI defense attorney from our US Attorneys directory is critical to saving your driving privileges.

Automatic License Suspensions for Refusal

Indiana's Implied Consent law is detailed in Ind. Code § 9-30-6-1. It states that any person who operates a vehicle in Indiana implicitly consents to submit to a chemical test of their breath, blood, or urine. If a police officer reads you the official implied consent warning and you say 'no,' or if you fail to provide a sufficient breath sample, the officer will immediately seize your driver's license.

Under Ind. Code § 9-30-6-9, the penalty for refusing the certified chemical test is severe. For a first-time refusal, the BMV will automatically suspend your driving privileges for one full year. If you have a prior OWI conviction on your record, the suspension jumps to two years. While standard driving privileges without restrictions are unavailable, Indiana law under Ind. Code § 9-30-16-1(a)(2) and Ind. Code § 9-30-6-8(d) allows a judge to grant you Specialized Driving Privileges (SDP) on the condition that you install a certified Ignition Interlock Device (IID) on your vehicle.

Can You Challenge an Implied Consent Suspension?

Yes, but the window is extremely narrow. Your defense attorney can file a petition in a local court, such as the Lake County Superior Court, Crown Point, to challenge the BMV suspension. To win, your lawyer must prove that the officer lacked probable cause to pull you over, failed to read the required Implied Consent warning properly, or that your 'refusal' was actually a physical inability to complete the test (such as an asthma attack). If the judge agrees, the refusal suspension can be lifted.

Portable Breath Test (PBT) vs. Certified Intox EC/IR II

It is vital to understand the difference between the roadside breathalyzer and the certified machine at the police station. When an officer pulls you over, they may ask you to blow into a small, handheld device called a Portable Breath Test (PBT). During a standard traffic stop for suspected OWI under Ind. Code § 9-30-6-1, the roadside PBT is a voluntary preliminary tool to establish probable cause, meaning you can refuse it without facing an infraction or license suspension. Refusing a PBT is only a Class C infraction if the officer offers the test following a crash resulting in serious bodily injury or death under Ind. Code § 9-30-7-5. PBT results are generally not admissible at trial to prove your BAC; they are only used to establish probable cause to arrest you.

Indiana's implied consent law only applies to the certified chemical test-usually the Intox EC/IR II machine (certified under 260 IAC 2.5-4-1) located at the police station, or a blood draw at a hospital. You can legally refuse the voluntary roadside PBT during a routine stop, but once arrested and read the warning, refusing the certified test triggers the heavy penalties.

Forced Blood Draw Warrants in Indiana

If you refuse the certified breath test at the station, the investigation does not end. Indiana police officers are trained to immediately contact an on-call judge to secure an electronic search warrant for your blood. In modern OWI enforcement, judges can sign these warrants digitally within 15 minutes.

Once the warrant is signed, the police will transport you to a local medical facility, such as a hospital in Fort Wayne or Evansville. Under precedents like Schmerber v. California, 384 U.S. 752 (US Supreme Court 1966), police have the legal authority to use reasonable force to extract your blood if you physically resist a valid warrant. Therefore, refusing the initial test often results in a painful blood draw anyway, combined with the automatic one-year BMV license suspension.

Step-by-Step Process After a Refusal Arrest

Navigating the aftermath of a chemical test refusal requires quick action to protect your legal rights.

Step 1: The BMV Notice of Suspension

After your arrest, the officer sends an affidavit of refusal to the BMV. The BMV will quickly issue a notice that your license is suspended for one year. You will not be allowed to drive while your criminal case is pending.

Step 2: Request a Refusal Hearing

Your attorney must file a prompt motion in the criminal court where your charges are pending to contest the probable cause and the validity of the refusal. This hearing is your only chance to reinstate your license before the criminal trial concludes.

Step 3: Review the Bodycam Footage

Your defense lawyer will meticulously review the police bodycam footage. Indiana law requires officers to read a specific, legally mandated warning advising you of the suspension consequences. If the officer paraphrased the warning incorrectly or failed to read it, the refusal can be thrown out.

Step 4: Defend the Criminal OWI Charge

Even if you refused, the prosecutor will still try to convict you of an OWI based on the officer's observations (slurred speech, poor balance, odor of alcohol) and the results of any forced blood draw. Your attorney will fight these charges at a pre-trial conference or trial.

How Much Does it Cost in Indiana?

Defending an OWI refusal case is complex and involves several costs.

How Long Does the Process Take?

The BMV administrative suspension for a refusal takes effect almost immediately after your initial court hearing and lasts for 12 to 24 months. Resolving the actual criminal OWI charges typically takes between 4 and 9 months. If your attorney successfully challenges the refusal in court, your driving privileges could be restored in a matter of weeks, highlighting the importance of hiring legal counsel immediately.
