Nope Ca is different with that stuff. Anything with a bed is a commercial vehicle (pickup, flatbed, big trucks, and even el caminos) We have a plate with all number and 1 letter. All cars (or a pickup with a permanent camper shell) can be registered as a passenger vehicle and has a plate with 3 letters and 4 numbers. It's dumb, but no special farm or truck plates for pickups. We do have ag exemptions for our 2.5 ton flatbeds we use to move tractors and stuff with, because they travel less than 18,000 miles a year they haven't had to been updated to all the new emissions standards until 2017. But we really are fucked when it comes to trucks, because now that the state has been regulating trucks, we will either have to repower our internationals, or sell/scrap them and buy new trucks. Same for all the truck fleets statewide. And the imbeciles want to start regulating diesel tractors, so we may end up having to stop using all our old tractors from the 70s and 80s, which still run perfectly fine, because of the premise that its an older diesel and 'must be dirty' even though they are more fuel efficient than our brand new tier 4 tractors are.
So like I said above it really is like living in a communist country, and they are trying to regulate out the only successful business keeping our economy alive right now which is farming and trucking.
Sorry for the rant, but just trying to make it clear for the rest of you because a lot of this never makes it in the new even locally. As it stands any vehicle 1975 and older does not have to be smogged. But smog tests are only done in the populated counties along the coast and central valley. As soon as you live in a foothill or mountain county there are no required biennial smog checks because so few people live there comparatively The whole situation is fucked!
