Passing the Diesel Smog Test

First of all, who has to get a smog test done on their diesel powered vehicle? (Courtesy of the California DMV website)

Effective January 1, 2010, smog emission inspections are required for diesel-powered vehicles manufactured in or after 1998, and have a gross vehicle weight rating (GVWR) of 14,000 pounds or less for original registrations and transfers. Biennial smog inspection requirements will be phased-in beginning with a registration renewal date of April 30, 2010. (If you need a smog on your diesel vehicle, you'll be notified by the DMV the same as a gasoline powered vehicle)
