Navigating the legal landscape surrounding DUI stops in Indiana can feel overwhelming, especially if you’re facing charges or concerned about the consequences of refusing a breathalyzer test. This guide breaks down essential information about drunk driving laws, your legal rights, and the implications of providing or refusing a breath sample during a traffic stop.
We’ll also address common misconceptions about Indiana’s DUI laws, explain potential penalties, and offer guidance on when to seek legal help. By the end of this guide, you’ll be better equipped to understand your rights and make informed decisions.

Introduction to Indiana DUI Laws
Indiana takes drunk driving seriously. Under Indiana Code 9-30-5-1, driving with a blood alcohol concentration (BAC) of .08 or higher is illegal. However, you can still face drunk driving charges, even if your BAC is below this threshold, if law enforcement believes your driving ability is impaired.
Understanding the laws surrounding DUI stops and breathalyzer tests can help you avoid costly mistakes, such as losing your license or facing harsher penalties.
Implied Consent Law Explained
Indiana operates under an Implied Consent Law (Indiana Code 9-30-6). This means that by driving on Indiana roads, you automatically consent to chemical tests (including breath, blood, or urine tests) if law enforcement suspects you of intoxicated driving.
Important Details About Implied Consent:
- Timing: You must comply with the officer’s request at the time of the stop. Refusing doesn’t exempt you from consequences.
- Applicable Tests: The law covers breathalyzer tests done at the scene and official chemical tests often conducted at a medical facility.
Consequences of Refusing a Breathalyzer
Refusing to take a breathalyzer test doesn’t mean you escape penalties. Under Indiana’s Implied Consent Law, refusal results in an automatic license suspension, even if no drunk driving conviction follows.
Here’s what to expect if you refuse a breathalyzer test in Indiana:
- First Refusal: 1-year license suspension.
- Subsequent Refusals: 2-year license suspension.
More importantly, your refusal can be used as evidence against you in court, potentially leading to harsher sentencing if you’re convicted of DUI charges.

Legal Rights During a Drunk Driving Stop
It’s critical to understand your rights when stopped by law enforcement. While Indiana’s Implied Consent Law obliges you to submit to chemical testing, you still maintain other rights under the law.
Key Rights to Remember:
- You Can Remain Silent: You’re not required to answer questions that may incriminate you. Politely inform the officer that you wish to remain silent.
- Right to Legal Representation: You can request an attorney, especially during questioning.
- Police Must Have Probable Cause: The officer must have reasonable suspicion to pull you over and request a breathalyzer test.
- Misconception alert: Police do not need to read you your Miranda rights unless you are formally in custody and being interrogated.
Factors Affecting Breathalyzer Results
While breathalyzer tests are commonly used in DUI investigations, it’s important to know that they’re not infallible. Several factors can affect the accuracy of these tests, including:
- Medical Conditions (e.g., acid reflux or diabetes) that may cause false positives.
- Calibration Issues if the device is not maintained or used properly.
- Time of Test as BAC levels rise after initial alcohol consumption and may not reflect impairment at the time of driving.
These potential inaccuracies can provide grounds to challenge the results in court.
How to Challenge Breathalyzer Evidence
Breathalyzer results may carry significant weight in court, but they’re not always airtight. With the help of an experienced DUI attorney, you may be able to challenge the validity of the test.
Here’s how evidence can be disputed:
- Calibration Records: Was the device properly calibrated and maintained?
- Officer Training: Was the test administered by an officer trained to use the equipment?
- External Factors: Were medical conditions or environmental factors considered?
Successfully challenging breathalyzer results could result in reduced charges or even dismissal of your case.
