(3) Advertising in trade publications and contacting trade associations.

(d) Each public entity purchasing or leasing used rapid or light rail vehicles that are not readily accessible to and usable by individuals with disabilities shall retain documentation of the specific good faith efforts it made for three years from the date the vehicles were purchased.
