I have recently become aware of this, though I don't remember seeing it in here, though that I would pass it along.
This is from the CA DMV website:
Diesel-Powered Vehicles — Operative January 1, 2010
Amend, Repeal, and Add: Health & Safety Code §§44010.5, 44011, 44012 (AB 1488 Chapter No. 739)
* Adds diesel-powered vehicles manufactured after the 1997 model-year that have a gross vehicle weight rating of less than 8,501 pounds to be in the biennial smog check program.
It can be found here:
Any thoughts? or dare I say it "Comments?"
I am glad (for now) that I have a '97.
