The OWI Law in Indiana
In Indiana the offense is OWI, and the limit is 0.08.
Driving in Indiana is consent to a breath or blood test when an officer has cause to suspect OWI; the license case that follows a refusal or a failed test is run by the Bureau of Motor Vehicles, separately from the criminal case.
Who Makes OWI Arrests in Hammond
The Lake County Sheriff's Office and the agency that reports for Hammond (filed by the FBI as Hammond Police Department) make the OWI arrests in and around Hammond.
The FBI's agency list also places these agencies in Lake County: Indiana University at Northwest (campus police); Indiana Harbor Belt Railroad (other agency).
