Well, not exactly. Vehicles registered in Wisconsin are only subject to
emissions testing if they're garaged in one of the southeastern counties (in
the Milwaukee area). And then only because it's mandated by federal--not
Wisconsin--law.
>From the WISDOT web page:
The federal Clean Air Act spells out air quality standards
that all areas of the United States must meet. Southeastern
Wisconsin is one of over 90 metropolitan areas in 35 states
with air pollution levels higher than federal health standards.
About one-third of volatile organic compounds (mostly
hydrocarbons) and 60% of carbon monoxide present in this
area are due to automobile emissions.
And it does not appear that collector plates have anything to do with it,
since all "vehicles more than 5 model years old are required to be tested at
the time of change of ownership."
And the testing is free.
Although I have an opinion as to the efficacy of emissions testing for
automobiles, I'll keep it to myself. Let me only suggest that statements
like "our air got better without emissions testing" and "our air got worse
after emissions testing was required" prove nothing.- there are many other
sources of air pollution, and substantial investment in reducing ALL sources
of air pollution in the past 30 years. Some were effective, some weren't.
The real question is what would have happened to our air if we'd done
nothing.
