About truck policies enacted by the State of California.

California has a new policy on emissions from older diesel engines to reduce air pollution and improve air quality.

Specifically, the policy requires large trucks, public transit vehicles, and other commercial diesel vehicles operating in California to phase out older, higher-emitting diesel engines and use new or modified engines that meet stricter emissions standards . The policy will help reduce emissions of pollutants such as nitrogen oxides (NOx), thereby improving air quality.

This policy is in response to environmental protection initiatives and to improve the environmental protection level of the transportation industry. It will place new requirements on operators and fleet operators to adapt to greener transportation requirements.

Recently, California enacted a new policy that plans to ban the sale and registration of new diesel trucks starting in 2036, an initiative aimed at reducing tailpipe emissions and improving air quality.

Specifically, the policy states:

• Starting in 2031, new trucks must meet stricter emissions standards in order to be registered.

• Starting in 2036, the registration and sale of new diesel trucks will be banned. This means that after this date, no new diesel trucks will be launched on the market.

The policy aims to drive the transport industry towards greener technologies and fuels to lower tailpipe emissions, improve air quality, combat climate change and reduce negative health impacts.

There is actually no latest news about california banning diesel exhaust fluid, and there is no policy in this regard.
