New law in CA

[tomkatprop]

CA has a bill that took effect Jan 1st all diesels older than 2010 over 26000 lb must be off the road it includes trucks and buses what about motor homes

[smacdiesel]

That only applies to commercial vehicles.

I hope so all motor homes have commercial license plates and registered in CA

Going to be a lot of government diesels getting replaced. Transit and school buses, fire trucks, curb side pickup trash trucks. Probably a bunch that need to go but also a bunch with a lot of life remaining.

Does not apply to privately owned vehicles.

Why 2010? Those engines had DEF. so why that cutoff date?

[Gooma]

Just an abitrary cutoff date. No reason.

I'm going on memory, so my numbers may not be exactly right, but the emissions controls first required back in 2007 have gotten more strict over the years. First, there was the initial "current" restrictions back in 2007, then they got stricter back in 2013 or 2014 (why Cummins dropped the ISC and went to scaled back horsepower versions of the ISL instead), then stricter again in 2017. Why 2010, don't know, but I do know that the engine emissions have supposedly become cleaner with each revision. (The 2017 revision is the requirement for the quality of DEF sensor, which is what those common DEF head failures are about).

Maybe: "Then, the EPA tightened the restrictions even more in 2010. The agency required medium- and heavy-duty vehicles to step it up a notch by reducing engine emissions, especially for NOx and particular matter (PM) by incorporating DEF."

Just my opinion on the date, about 2008 was the year DEF engines came out. At the time any engines produced prior to the DEF requirement would be allowed to be put in vehicles manufactured after the 2008 date. Using 2010 as the cutoff for the new law probably has something to do with allowing 2 years to get all those older engines cycled through.

I doubt that motorhomes are covered, because they aren't commercial vehicles and are such a minimal number, as compared the commercial diesels which are the target of the law.

Also, the fact that a vehicle is privately owned won't exempt it from the law. If I privately owned a dump truck that is over age and over the weight trigger and is used for commercial business, the registration will not be renewed.

These vehicles will be recycled out into other states that do not have such restrictive laws.

From the link:


After combing through the regulatory code, we found two exemptions for truck and RV users:

California Code of Regulations, Title 13, Division 3, Chapter 1, Article 4.5, section 2025(c)(10) and (12).
Section 2025(c) are the list of “EXEMPTIONS” to the regulation and lines (10) and (12) read as follows:

(10) Motor homes for non-commercial Private use;

(12) ”Trucks with a GVWR of 19,500 lbs or less with a pick-up bed used exclusively for personal, non-commercial, or non-governmental use; and”

I believe that DEF did not become mandatory by the EPA until 2010. As I recall, some commercial trucking companies were buying new trucks over the past decade and installing pre-2010 engines in them to avoid DEF but still have new trucks. Now that's over.

Nope - motorhomes carry the same plates as cars. Pickup trucks are registered as commercial.

DEF came in with the diesel emissions standards that went into effect for engines built after 1/1/2010. Most 2010 model year vehicles had engines built earlier.
The new CA law applies to PRE-2010 diesel vehicles over 26000 lbs GVWR and private vehicles like most motorhomes are exempt.
