What modification was made to the Smog Check program in 2002?

• A. Smog Check was canceled for all vehicles.
• B. OBD inspections replaced all other testing.
• C. New vehicles were exempted from Smog Check for the first six years.
• D. Smog Check requirement was expanded to every six months.

Answer: (C)

The modification tested is that new vehicles were exempted from Smog Check for the first six years. This change meant that cars off the showroom floor wouldn’t need to pass emissions testing for the initial six model years, after which they rejoin the standard biennial testing cycle. The idea behind this shift was to reduce costs and administrative burden for new-car buyers while relying on modern, durable emissions controls.

Smog Check wasn’t canceled for all vehicles, and the program didn’t eliminate other tests with a full OBD-only replacement. OBD inspections were added to help detect emissions-control failures, but they did not replace the broader testing requirement. And the requirement did not move to a six-month cycle; the testing frequency remained biennial for most vehicles.
