OK, interesting. In NY we have a mandatory yearly safety check for all vehicles but also an emissions check for specific classes of vehicles (ie: gasoline cars/trucks >=2 years old, but diesel passenger cars and EVs are exempt). Mostly the emissions test consists of connecting the state software/hardware to the OBDII port and having the car tell if it should pass or not.
