Representing the smog testers in the cluster of automotive shops on Topanga just south of Devonshire, K-T Smog Test Only is a reliable, quick provider of DMV smog certifications. Someone can also take a look at malfunctioning brake lights and deal with minor electrical issues. State law prohibits repair shops from issuing smog certificates, which makes K-T a convenient local option when the smog renewal notice shows up in the mail. For most small to mid-sized cars, the testing process takes less than a half-hour.
