California DMV Requirement

WHAT IS A SMOG CHECK?

California requires most vehicles to pass a smog inspection every 2 years to renew registration. We make the process fast, affordable, and stress-free.

As a licensed Test & Repair Station, we're authorized to both test your vehicle AND perform any repairs needed to help it pass — all in one place.
