If an officer requests a chemical test, Indiana law sets the driver’s duties. Under Indiana Code § 9-30-6-2, an officer must have reasonable grounds to believe a driver committed an offense covered by the statute before requesting a chemical test. Refusing a test causes an automatic license suspension and may affect a related criminal case.
How implied consent works in Indiana
Indiana’s implied consent law is part of the driving privilege. A driver who accepts a license agrees to chemical testing when an officer has reasonable grounds to believe the driver is intoxicated. Reasonable grounds require specific facts that show impairment. This is more than reasonable suspicion. Breath and urine tests fall under implied consent. Blood tests also must meet federal constitutional rules. Before testing, the officer must explain the legal consequences of the decision.
What happens right after you refuse
Refusing a chemical test can result in an automatic license suspension. A first refusal may lead to a one-year suspension. If the driver has a prior OWI conviction within Indiana’s applicable lookback period, the suspension may increase to two years. This administrative suspension is separate from the criminal case and does not require a new OWI conviction.
The driver receives notice of the suspension and may seek judicial review. Because strict deadlines apply, a timely challenge can be important. Depending on the circumstances, specialized driving privileges may also be available after the required waiting period. Eligibility rules are strict and depend on the facts of the case.
How refusal affects your criminal case
Prosecutors may use a refusal to submit to chemical testing as evidence. The Fifth Amendment does not bar this evidence. However, Indiana courts require the prosecution to show that the officer gave the required statutory warnings.
The key issues include:
- Required warnings: The officer must provide all warnings required by Indiana law before the refusal can be used as evidence.
- Procedural violations: Failure to follow required steps may support a challenge to the admissibility of the refusal.
- Other impairment evidence: A refusal does not prevent an OWI arrest or prosecution. Officers may rely on field sobriety tests, their own observations, witness statements and other available evidence of impairment.
An OWI case may involve alcohol, blood alcohol levels or controlled substances. Officers must still prove impairment with available evidence.
What Indiana drivers should know after a refusal
A chemical test refusal in Indiana can lead to two separate cases. The license may get suspended without a conviction or a separate court hearing. The deadline to challenge the suspension is limited. The criminal case moves forward separately. A prosecutor may use the refusal as evidence, but it does not prove impairment. The prosecution must still prove impairment.
