Smog Check Inspector Level 1 Practice Test – Complete Exam Prep 2025

Question: 1 / 400

Why is it important to find the EO# on aftermarket parts during a Smog Check?

It verifies the part’s functional compatibility

It determines if the part is emissions-compliant

Finding the EO# (Executive Order number) on aftermarket parts is crucial during a Smog Check because this number indicates whether the part is emissions-compliant. The EO# signifies that the aftermarket component has been tested and approved by the California Air Resources Board (CARB) or another regulatory authority for use in vehicles without violating emissions regulations.

When a vehicle undergoes a Smog Check, one of the key objectives is to ensure that all components related to emissions control are not only functional but also meet specific environmental standards. If an aftermarket part does not have an EO#, it could potentially contribute to increased emissions and could lead to failing the Smog Check, thereby ensuring that the vehicle adheres to legal and environmental requirements. This focus on emissions compliance is vital for both regulatory reasons and for environmental protection.
