CA Diesel Smog

[Dribble]

I have had to smog my '06 Ford diesel the last 3 years in a row. I thought all diesels had to be smogged every year now.

Answer: For gas-powered vehicles the 1976 model year is the earliest model year vehicle required to participate in the biennial Smog Check Program. Vehicles six years old and newer are not required to participate in the biennial Smog Check Program.
For diesel-powered vehicles 1998 model year and newer 14,000lbs and less are subject to the biennial Smog Check Pragram. The six year exemption does not apply to diesel vehicles.

If you're getting the notice every year then BAR needs to be made aware of this.
