I'm sure it changes with each station. I've taken my truck to some places and they tell me I needed mud flaps on the front tires or some other bogus thing and that he wouldn't pass me. I go to another place and they'd shake their heads when I mentioned it and would pass me. Seems like the inspection process is kind of a joke if you ask me. Then again, I'm coming from a state (AZ) where they don't do inspections. As long as you pass emissions out there, you're fine.
