There has been talk of including Diesel Powered Vehicles in the testing. But,the largest city in AK repealed its emissions testing stating todays vehicles burn cleaner then the older vehicles we use to see. So I don't see how the diesel power fits in the picture. Since the crack down on vehicles with HID,nothing would surprise me. I do know that OTR trucks that get stopped for inspections are going through visual inspections as well as a smoke test. I don't know any more then that
