(a) Zero-tolerance policy.--A transportation network company shall implement and enforce a zero-tolerance policy on the use of drugs or alcohol by a transportation network company driver while providing transportation network service. A transportation network company driver who is the subject of a passenger complaint alleging a violation of the zero-tolerance policy shall be immediately suspended by the transportation network company. The suspension shall last until the time the complaint investigation is complete. The following information shall be provided on a transportation network company's publicly accessible Internet website:
(1) Notice of the zero-tolerance policy.
(2) Procedures to report a complaint about a transportation network company driver with whom the passenger was matched and whom the passenger reasonably suspects was under the influence of drugs or alcohol during the course of the ride.
(b) Speech disability.--In investigating a zero-tolerance complaint against a driver with a speech disability, the transportation network company shall factor the driver's speech disability in the investigation and inquire whether or not the complaint is based on an erroneous perception of the driver's speech disability.
