California Smog Certification on Chula Vista's Broadway corridor holds BAR Station #221240 and operates as a STAR-certified Test Only facility at 1655 Broadway Suite 1, performing emissions inspections without selling repair services. The Test Only designation means vehicles flagged by the DMV for enhanced inspection must test at a STAR station before registration renewal, and post-fail repair work routes to mechanical shops including Midas on the same Broadway commercial strip. Inspectors run OBD-II and BAR-97 tailpipe protocols on passenger cars, recreational vehicles, commercial trucks, out-of-state transfers, and change-of-ownership vehicles, transmitting certification data electronically to the DMV upon passing. Fleet operators maintaining multiple registrations cycle vehicles through the Broadway station for annual compliance, a scheduling pattern shared with commercial transportation providers including EZ CAR RENTAL that run smog on rotating inventory. The station's BAR-97 dynamometer lane loads vehicles to 15 and 25 mph cruise speeds while sampling HC, CO, CO2, and NOx concentrations through a five-gas analyzer calibrated to CARB-mandated cut-point thresholds.
