Refusing a Breathalyzer in Indiana
Indiana, like all U.S. states, has an implied consent law. By driving on Indiana roads, you implicitly consent to chemical testing (breath, blood, or urine) if lawfully arrested for DUI. Refusing a test will typically result in automatic license suspension, separate from any DUI conviction, and the refusal can be used against you in court.
DUI vs. DWI in Indiana
Different states use different terminology. Indiana uses DWI (Driving While Intoxicated) as its primary statute, though both alcohol and drug impairment can result in charges.
