Maine state inspection criteria stipulate that any warning lights (including the ABS light) must be functional and display properly. When the ABS light is on, it means that the car's computer has detected a malfunction or fault in the ABS system. Inspectors conducting safety inspections typically check for these indicators of malfunctions, and a visible ABS light can result in an inspection failure.
It's worth noting that individual vehicle conditions and inspector judgment may vary during inspections. However, to prevent the issuance of a failed inspection certificate or sticker, it's highly recommended to address any illuminated warning lights, including the ABS light, by having the relevant issues diagnosed and resolved at a certified repair facility or trusted auto mechanic prior to presenting the vehicle for inspection.
