In my state (Utah) since having a working ABS system on vehicles isn’t specifically spelled out in the state vehicle inspection guide, some stations leave it up to the inspector to determine whether or not they want to pass the vehicle with an ABS light. I’ve seen some pass the vehicle, I’ve seen some pass with a warning, and I’ve seen some fail the vehicle. It gets down to a judgement call. Other inspection stations have a “station policy”, to always fail a vehicle with an ABS light on. And rationally thinking, you have the same braking ability as over 50% of the cars on the road if you have an ABS light on. When I had my inspectors license, I was probably a hard a$$ and failed more than I passed with the ABS light on. It depended on the rest of the car, as well as the customers attitude.
