Section 22 of Chapter 40 of the General Laws, as appearing in the 2008 Official Edition, is hereby amended by adding, at the end of the third paragraph thereof, the following sentences:-  The licensing authority that issues taxicab licenses or hackney carriage licenses, shall also issue an official identifying document, separate from a license or hackney license, to be placed in the rear interior of the vehicle with the drivers identifying picture, name and hackney or licensing number. This document shall be formatted so as to travel with the operator from cab to cab.  Each cab shall also have affixed in the interior rear of the vehicle  the name or the trade name of the company, company phone number and either the medallion number or vehicle number.  Both designated documents shall be visibly affixed either on the partition behind the head of the driver or on the head rest of the driver so as to be made visible to passengers inside the vehicle.

The licensing authority may designate the manner in which they provide such documentation to an authorized driver and the manner in which such document is affixed inside the vehicle.
