The other day I failed my emissons control test simply because my car was emitting too many hydrocarbons. But one thing that I notice is that nobody seems to mind when big trucks and busses spew out these huge plumes of thick black smoke.

Most large trucks and buses are powered by diesel engines. The truth is, Joe, that although the exhaust from a diesel powered vehicle is more visible, in fact, it emits far fewer actual pollutants than does the exhaust of a gasoline powered automobile. And by the way there are emission standards for diesel powered trucks and buses, so the ones you claim were "spewing out huge plumes of thick, black smoke" were probably operating within their legal standards.

It's a scam by the automotive industry. There used to be a "light rail" system where there were trollies in many cities (not just San Francisco.)
But the big nasty automotive industry bought up the trolley system, ripped out the rails, and installed a bus system in many cities. But, with the advent of cars, many busses don't even run in small towns, not even Greyhound.
I'd say lobbying has something to do with it.
And they're not any different. Bigger, yes, but it's not like your car's steam-powered and a truck is run by a bunch of truck trolls. Buses aren't dragon-powered. They're all internal combustion. Their manufacturers have just lobbied to get less-stringent rules for their emissions.
And don't get me started on the smoke spewing from factories! Why don't THEY have to get inspections on their emissions?

My guess is those over the road trucks are licensed in another state in which emission standards are not so high. Lots of them are licensed in Ohio for some reason, so I would imagine that's how they get away from the emissions standards.

Trucks have emission regulations, also. Older trucks have fewer regulations than newer ones. Older trucks do emit more emissions, but with each passing day, there are fewer on the road. The new trucks are far more efficient and clean than the older ones, and we now pay $30,000 more for that new truck than you would have paid for an older one when it was new.
When you consider the weight being transported, trucks do not emit any more emissions, percentage wise, than do cars.

What's your point? Trucks and buses are worse, so why are they picking on me?
Different rules for different vehicles, changing dramatically now for diesel with the new mandated low sulfur diesel fuel.

Trucks have tests too. It is slightly different but if tons of black smoke is coming out, they will fail also.

the way I see it is; You need a tune-up-- Hopefully all the big-riggs will eventually switch to bio-diesel Its so much cleaner burning and smells like a deep fryer

They are considered different types of vehicles and so have different rules...which makes sense being as how they are completely different.

Yeah thats right, then they claim that diesels burn cleaner than gas engines..... I dont know about that..... maybe you need to move to a state they dont do emmison testing.
