A POVs (personally operated vehicles) where I live have to have pollution checks until they can officially be classified as antiques--even pickup trucks. I have a 1990 F-150 that, with luck just passed its pollution check for the last time. Going to do my best to get an antique tag on it before it comes due for the next one in two years. Not that it risks failing (thing had remarkably low numbers for its age) but simply the fact that it's a true survivor.
