(b) No vehicle, engine, or trailer shall be accepted by the ARB as a representative vehicle, engine, or trailer for enforcement testing unless the following criteria are met:

(1) California certified and registered.

(2) Odometer indication of less than certified useful-life mileage and vehicle and trailer age within useful-life time period.

(3) No indication of abuse (e.g., racing, overloading, misfueling, or other misuse), neglect, improper maintenance or other factors that would have a permanent effect on emission performance.

(4) No major repair to engine or major repair of vehicle and trailer resulting from collision.
