Smog Check stations caught using “clean gassing” to issue fraudulent certificates
SACRAMENTO, CA – The Bureau of Automotive Repair (BAR) has filed, for prosecution by the Attorney General’s Office, accusations against nine Smog Check stations because investigations showed them to be issuing fraudulent certificates.
Through analysis of Smog Check Program data, BAR investigators detected the Smog Check stations to be engaged in the practice of “clean gassing.”
“Clean gassing” is the act of introducing a surrogate gas into a test vehicle’s exhaust emissions sample to fool the inspection system into passing that vehicle. This fraudulent activity undermines the integrity of the Smog Check Program and threatens the air quality for all Californians.
The accusations allege numerous violations of the Automotive Repair Act, including fraud, false and misleading statements, and violations of the Motor Vehicle Inspection Program.
