Has the EPA ever decertified a vehicle before?
I'm not familiar enough the US system to know what happens if they do. I assume, since they okay what's allowed on the road (emissions wise), if they decertify they are saying they are no longer legal - same as not passing a vehicle at all.
Wouldn't that mean states are no longer allowed to register them? I'm guessing at that point the actual emissions no longer play a part in it since it's strictly a registration/road worthiness issue. It'd be like me taking in an ATV and wanting to register it as a light passenger vehicle - it's not certified for it and would not be allowed. (probably a poor example but you get the idea )
