What is the emission standard for cars from 2006?

[DeKathryn]

2006 vehicles generally comply with China II or China III emission standards. Methods to check your car's emission standard: 1. Look at the back of the vehicle's environmental protection compliance label to easily identify the emission standard; 2. Check the first page of the vehicle qualification certificate, which contains emission standard information (though not directly stated as 'China X', but rather as a string of characters); 3. Estimate the emission standard based on the vehicle's manufacturing year; 4. Take the vehicle registration certificate to the local DMV for verification. Automotive emission standards regulate harmful gases and substances in vehicle exhaust, such as carbon monoxide and hydrocarbons, and fall under environmental protection regulations.
