Yep, it’s the road sign part that gets me confused. I live in Tennessee. I suppose that makes some sense but I still don’t know if I understand why it needs a sign vs just having an ordinance and fining people who don’t follow it. In my brain, road signs are for things you might need to know in the spur of the moment. It’s not like people are going “Whoops I just built an unapproved driveway!”
