What year the car have to be take emission test?

The year a car has to take an emissions test varies greatly depending on your location (state, province, country). There's no single answer. Some areas don't require emissions testing at all. Others have different rules based on the vehicle's age, type, and sometimes even the fuel type.

To find out when your car needs an emissions test, you should:

* Check your state/province's Department of Motor Vehicles (DMV) website. This is the most reliable source.

* Look up your local emissions testing regulations. Your county or municipality might have specific rules.

* Consult your vehicle's registration documents. Sometimes, information about emissions testing requirements will be included.

Without knowing your location, it's impossible to give you a definitive answer.
