What is the primary source used to determine a vehicle's emission control requirements?

Explanation:
The main idea is that the emission-control requirements for a vehicle are specified by the Underhood Emission Control Label. This label, located in the engine compartment, lists the engine family, model year, and the exact emission-control components and standards the vehicle was designed to meet. It serves as the authoritative reference for what parts and systems are required to pass the smog program. The other documents—Vehicle Title, Owner's Manual, and Service History—cover ownership, usage instructions, and maintenance records, but they do not codify the technical emission-control requirements for that vehicle.
