We have a number of cruise nights starting in April and running into late Fall here around Nashville. There is no vehicle inspection here in TN., except for in metropolitan areas there is annual emissions inspection, and older cars are exempt from it. It's not like PA., where we had the left front window inspection sticker system. When your annual vehicle registration comes up for renewal (handled through the county in which you live) you have to take your regular driver/late model car to the local emissions testing station and they charge you $10.00 for the test. The "passed" certificate goes in with your application for registration renewal and the county sends you either the new sticker for your tag or a new tag.
I was a PSP Trooper in PA. and it took me a long time after I left that job to stop looking at oncoming cars to see if their inspection sticker was valid; used to stop quite a few of those.
