I'm not talking about semi trucks, but regular sized ones (Dodge, Ford, Chevy, etc.) They put out soooo much black smoke. Why do some states allow them to be exempt while other cars and trucks that run on gasoline have to be clean burning? Doesn't seem fair.

Because the black smoke you see is not anywhere near as bad as if it were invisible or white smoke. The black is carbon particulants that are bio-degradable. Gasoline exhaust expels terrible gases that are not bio-degradable and are loaded with elements that cause pollution.
Diesels are 94% cleaner in black exhaust than gasoline exhaust which you cannot see except on a cold day.

that's a funds grab for the state. i've got lived in long island the place this is required each and each year. multiple the products checked are merely ridiculous and fee extra then what i could evaluate paying. Now that I stay in Michigan, they tried for some years to enforce a application in line with exhaust produces. the subject exchange into it pertained basically to 3(3) counties. If the examined motor vehicle exchange into much less then ten(10) years in age, it had to be examined. If it failed, the owner exchange into in charge for maintenance, till reported maintenance could exceed the fee of the motor vehicle. finding at multiple the 'automobiles', in case you may call them that, here could be junked. human beings do no longer do preventative maintenance, as they could. If the windshield is broken, replace it, no longer here, merely shop on using till the wheels fall off. in case you think of this is undesirable in PA, do on no account stay in Bermuda. The inspection there are each and every six month. If there is basically a rot hollow in 1 / 4 panel, it falls. If the paint is primed and not a finished coat, it fails. So there are good and undesirable in all. the key is to maintain your motor vehicle, locate a 'uncomplicated' mechanic and shop rolling.

The reason is the prohibitive cost for diesel exhaust analyzers, starting in model year 2007 all diesels have federal OBD 2 emission standards, so their days of getting by without being tested are over
by the way diesels produce tons more Nox gases than gas vehicles so don't believe that they're environmentally friendly at all

Because it's a state by state law not a national law

In the state I live in it's a county by county thing. The county I currently live in does not require it. But the county I'm from does and so does many others.

Some states still don't require state inspections.
