Here in Valpo we have to get emissions testing every 2 years on older model cars. I assume it's something similar to that, TIS.
In Ohio some counties have the emissions test. Where I live you don't have to. When we lived in VA we had to get a safety inspection every year.
I'd never even heard of it until I moved up here...
Long as I remember The rain been coming down. Clouds of Mystery pouring Confusion on the ground. Good men through the ages, Trying to find the sun; And I wonder, Still I wonder, Who'll stop the rain.
