Paul's Smog Check in Lakeside's River Shopping Center has served as a STAR-certified test-only emissions station at 10199 Riverford Road since 2006. The station's BAR test-only license restricts the operation to diagnostics and certification — vehicles failing HC or CO thresholds receive repair referrals to nearby shops, including JNB Automotive in the same River Shopping Center complex for engine and exhaust corrections. Biennial, change-of-ownership, and out-of-state smog checks all run through the BAR-97 Emissions Inspection System, which scans OBD-II readiness monitors and performs tailpipe gas analysis under the state's rolling-idle protocol. Continuous operation at the Riverford Road location since 2006 has established the station as a fixture in Lakeside's biennial vehicle registration cycle. DMV-directed testing — where the state specifically requires a STAR station — routes through the same calibrated analyzer, supporting the compliance pipeline for vehicle purchases at East County dealerships including Red Star Auto Inc. on Maine Avenue. The BAR-97 system's two-speed idle test measures hydrocarbon and carbon monoxide concentrations at 15-mph and 25-mph dynamometer loads, cross-referencing results against year-specific CARB cutpoint tables.
