About ALL SMOGGED MOTORS
All SMOG Motors was built to solve a problem created by California's Clean Truck Check program. Since the rollout began in 2023, owners of 2013 and newer diesel trucks have had to deal with semi-annual emissions testing, registration holds, and confusing compliance rules. We specialize in OBD testing for heavy-duty trucks with 2013 or newer engines and a GVWR over 14,000 pounds. These vehicles require OBD data scans with CARB-certified equipment, not smoke opacity tests. Serving Los Angeles and Riverside County, CA, we help truck owners stay compliant and avoid delays, penalties, and DMV registration issues with Clean Truck Check requirements.
