RATE CARD: All cabs shall be issued a rate card, by the Division, which shall be assigned to specific vehicles and shall not be transferred (see Appendix A "Marking Specifications for Cabs" § 2.16 of this Part). At all times during operation of the cab, said rate card shall be displayed in a bracket or receptacle of a type approved by the Division so as to be visible to any passenger in the cab. The numbers on the rate card shall correspond to the registration number and meter serial number of the particular cab. A new rate card shall be issued each time a vehicle is replaced or a taximeter is replaced or recalibrated. The rate card issued under this paragraph satisfies the requirement for a certificate memorandum set out in R.I. Gen. Laws § 39-14-7.
