Vehicle Emissions Inspection Program - Testing and Inspection - Grounds for Failure

This bill clarifies that Maryland vehicle emissions inspections can only result in a failure for three specific reasons: missing required emissions equipment, misfueling, or failing to meet emissions standards. It restricts inspectors from citing other grounds for failure during biennial exhaust emissions tests or emissions equipment/misfueling inspections. The law applies to all vehicles subject to Maryland's emissions testing program, effective October 1, 2026. This change standardizes inspection outcomes by limiting failure determinations to these defined technical issues.
