Many states require an annual vehicle safety inspection, often accompanied by an emissions test.

In Pennsylvania, I have to have my car tested each year. They make sure that tire tread depth, remaining brake pads, exterior lamps, and windshield wipers are all functional / within tolerance. There's other stuff that you can be failed for, such as excessive rust, etc.

That's one other thing to know about Ohio. Your car will rust. It's a cancer that will slowly eat your car, even if you do an undercarriage wash.

Some states do an annual safety inspection of vehicles - it's usually more or less "do your turn signals, brakes, and head lights work". Nowadays some states also need to do an emissions check. Some states require it every other year, some states I guess don't really require it at all?
