Oh how times have changed over the years. Its horrible in the US for inspections.You wouldn't believe the extent they go through here. Like this one time, at band camp, [emoji2]At the risk of wandering further off-topic, I just wanted to address this.
Vehicle testing in the USA is mandated on a state rather than federal level. Or to put it another way, it depends on where you are. Some states only care that the Check Engine Light isn't lit. Others - such as California unsurprisingly - include an extremely strict "smog check" or emissions test. A few have a test similar to our MOT. I grew up in Florida by the way, where there is no testing.
Interestingly, states in the "Rust Belt" - that's states that salt their roads in winter - generally don't have a full test. Nor do many states on the eastern seaboard (again with the salt, only this time from the ocean...). The logic seems to be that outside of major cities, a car is a necessity. And Americans will not stand for the government telling them that they have to get rid of theirs and buy another. Ironic, given that those are precisely the states where vehicles are likely to be falling apart at the seams.
So anyway, it's just a subtle little social difference toward cars that they have.
Actually though. If you live in counties around big cities here, which if yall arent familiar with county maybe Mako can help, then you have to do an emissions testing and safety inspection. I currently live in Ga. 13 counties mainly surrounding Atlanta you have emissions testing. They hook a computer up to the OBD2 port and make sure no codes are present basically. If everything checks out then your good. All except California. They test the gasses in your exhaust pipe with some sniffer thing that reads how much whatever is present.
If like me you live in whats considered a Rural or out in the country type county all you have is a safety inspection. And when I say safety I mean they check your window tint, all the lights outside your car, your seatbelts, and the horn, and possibly your tires. As well as making sure there is no cracks in your front windscreen that obscure your vision.
I can be missing my front wings have the rear wings smashed together and be able to pedal my car lile fred flintstone and it could pass. Thats what blew my mind when I saw everyone welding holes due to MOT. To me thats insane. Jane has absolutely 0 emissions systems left in her. Not catalytic converters, headers, no egr, and every bit of the emissions stuff under the boot is gone. And the solenoids for whatever on the firewall are gone. She would still pass if I could get her running because my lights work windsheild is fine and the seatbelts work. I can go as far as to tint every one of the windows behind the driver seat with rattle can spray laquer as long as I have both of my outside mirrors.
