Welcome to INGO.Just joined and maybe I am looking in the wrong place - I am wondering how this is all affected by the new Open Carry since July 1st, 2022 as the last post in this sticky was 2008.
First off, it is called Constitutional Carry or Permit less carry. Indiana hasn't cared wether you carry open or concealed. The Indiana Licence To Carry A Handgun or LTCH has never specified one or the other.
Previously if you didn't have a LTCH, transporting the firearm was simply unloaded, in a case of some sort, away from reach in the vehicle. Preferably the trunk or hatch.
For what it's worth, the LTCH, lifetime or 5 year, is now free. All you need to pay for is about $13 for fingerprints.
