If you’re talking about “parking lot laws” (the ones that protect your right to keep a firearm locked in your car at work), they’re mostly a U.S. thing and exist in a bunch of states, not just one or two big ones include Texas, Florida, Georgia, Tennessee, Indiana, Oklahoma, Kentucky, Mississippi, Alabama, Arizona, and a few others; the exact rules vary a lot though (some allow employer exceptions, some don’t), so it’s always worth checking your specific state’s version before assuming you’re covered.
