Let me guess, Lost Wages ('Vegas) or East E. Sacramento (Reno)?
The only two counties in the whole state that even HAVE emissions test.
They are also the Kali. beach heads here, university towns full of all that the university culture entails.
I could be more blunt but would get banned.
Nevada is now divided like many other states, rural freedom vs city center totalitarianism.
To be free you have to forego the opera and "art" museums.
I will look into this but expect that it was pushed from the Kali. side, the zealots there hate to lose control.
If you have a statute number my research would be simpler.
Twin-Cam Hemi, Webers, Headers, Overdrive, Disc brakes, and no emissions equipment to spoil it all. These are gonna be FUN rides!
