Following action by Recreational Vehicle Industry Association (RVIA) and its partners, the California Air Resources Board (CARB) amended its regulatory proposal on the heavy-duty inspection and maintenance program.

The amendment will exempt diesel motorhomes registered in states other than California as long as they are operating for non-commercial uses.

The new requirements were being developed last month, mandated by 2019’s Senate Bill 210, which would require diesel motorhome owners nationwide to obtain an annual CARB certificate to operate their vehicles on California roads.

“This is a huge victory for diesel motorhome owners in the other 49 states who wish to visit California in their motorhome,” RVIA Director of Government Affairs Mike Ochs said. “The original proposal would have only allowed a three-day pass before out-of-state diesel motorhome owners would have had to get a smog check done on their vehicle once they arrived in California. We were able to successfully explain why a three-day pass would be insufficient and unworkable for motorhome owners visiting California, and CARB agreed.”

The action followed the receipt of a letter from RVIA, the National Association of RV Parks and Campgrounds and the CampCalNOW RV Park and Campground Alliance. The California RV Dealers Association also submitted a letter supporting the three association’s comments voicing “deep concern” over the proposal.
