I asked I got a smog test last year and why do I need to get another one this year Im wating for an answer?

They write the rules and if you want to drive - you got to do another check up.  Your car wears out more every year you drive it, so what was clean last year may be burning oil this year.  You got to keep it in good condition.

I have too get one every year before I get my tag and I live in Georgia, near Atlanta. I lived in another part of Georgia and I did not need a smog test

The state wants more money. Simple as that.

Components get removed, modified or wear out. In Arizona, smog tests are every two years.

Yes.

That's an answer.

If where you live requires annual emissions testing, you must do it if you wish to drive, legally.

No one is answering because you likely didn't provide enough information.

Where do you live? That's important.

How old is your car? This can also be a determining factor.
