Here in NC, only 96 and newer cars get emissions inspections. Everything else gets safety-only.
But after cars are 35 years old, they don't even get that. My 81 is free and clear in 3 years.
But the 406 that's in it now is still no problem, since it's safety-only. I think "technically", they're supposed to just verify the smog stuff is on there, but nobody does.
Varies by county...my county has no emission testing at all. But my 77 is exempt from inspection anyway
