I have never had a car that was tested. I had a 75 Monza that was
tricked up to the point that I knew it would never pass when PG
started testing so I "moved" to my nieces house in Charles county (on
paper) where they didn't test until I moved to Florida (one tag cycle)
but by then I traded the Monza anyway. Down here they never tested.
That really surprised me when we were in Florida. I bought a used Ford
Ranger from a dealer to beat around in. I registered it in Florida and
got insurance from Allstate. The agent at Allstate told me I had to
have it inspected first and I assumed that meant a safety/emissions test
like up here in MA. Turns out it was just a check to make sure there
was no body damage that I could try to claim with Allstate. No safety
or emission tests in Florida.
