How often do you have to smog in CA?

[forsaken]

I always thought that it was once a year, but people have been telling me its once every two. Anyone know for sure?

[Rockenreno]

I believe its once every two years in most counties of California. In some its once every 4 (at least what I've heard).

It's once every two. Unless you have a new car, then I think you don't have to smog it for the first 5 years, but after that it's every 2 like everyone else.

I dont have smog testing.
