Under current law, a motor vehicle fails an emissions inspection solely because a check engine light is illuminated on the motor vehicle's dashboard, regardless of what the vehicle's actual emissions are. The bill directs the air quality control commission to submit to the federal environmental protection agency by May 5, 2021, a proposed revision to the state implementation plan that would
enable a vehicle that fails the on-board diagnostics test solely because a check engine light is illuminated on the vehicle's dashboard to undergo a tailpipe emissions test replace the existing on-board diagnostics test with an IM240 tailpipe emissions test as specified in guidance issued by the environmental protection agency, except in cases where the vehicle cannot be tested using the tailpipe emissions test, including where using the tailpipe emissions test would be unsafe.
