Do diesels have different/less polluting exhaust gases?

Gasoline major pollutant is Carbon Monoxide, which is poisonous, while diesel emits carbon Dioxide, not as toxic. Never hear of anybody locking himself in a garage with a Diesel to kill himself, have you? So yeah, diesel pollution is more visible but far less dangerous.

Diesels have different standards and different tests are involved.
Diesel's primary exhaust is particulate matter, so the main test is called the "opaqueness test". In 2006 CA has just restarted enforcing an old law that has been on the books since the 1980's about making all commercial diesel engines go pass the opaqueness test. VERY FEW places can do those.

Diesels are indeed a different exhaust. They burn the fuel without a spark, only needing heat for combustion. The fuel is burned more completely-to the point that it isn't worth checking for smog

Calif now requires a smog on diesels. Told by dmv to get a smog and call Bureau of Automotive Repair who verified that diesels do indeed require a smog test. Please update your website as you are giving outdated information

Beacuse highway diesel is mandated by California law to have low sulfur. And it is still taxed to high heaven. Ask any trucker and they would rather put red dyed diesel in their trucks. It is about half the price, except they would probably lose their license.

There is a a smog test of sorts, on diesel semi truck. It is called a snap throttle test.
The AQMD Air Quality Management Department can and do pull you over at scales houses and preform these test and will put you out of service if your truck is to dirty.

In Missouri, anything 1995 and older is exempt. Anything that does NOT run on gas is exempt. Any truck that has a gross vehicle weight of 8501 pounds or more is exempt even if it runs on gas. A Ford F-250, for example, usually has a gross weight more than 8500. Glory day's are here again. You should live here. LOL.

Diesels emit different pollutants. They do run much cleaner!
