Never understood the states with no safety inspection at the least. NC does both, emissions depend on county, and I don't see as many cars on the road that make me nervous to be around.
MN has neither. They did away with emissions tests...20 years ago? I don't think they've ever had a safety inspection, at least I don't remember it (I'm in my mid-50s), but maybe it was part of the emissions test at the time. Now I just fill out a quick form online every year for my new tabs and a week later get them in the mail and put them on.
