1. A transportation network company shall implement a zero-tolerance intoxicating substance policy for transportation network company drivers that disallows any amount of intoxication of the transportation network company driver while providing transportation network services. The TNC shall provide notice of the zero-tolerance policy on its website, as well as procedures to report a complaint about a driver with whom a rider was matched and whom the rider reasonably suspects was under the influence of drugs or alcohol during the course of the trip.

2. Upon receipt of such rider complaint alleging a violation of the zero-tolerance policy, the TNC shall suspend such TNC driver’s ability to accept trip requests through the TNC’s digital network as soon as possible, and shall conduct an investigation into the reported incident. The suspension shall last the duration of the investigation.

3. The TNC shall maintain records relevant to the enforcement of this requirement for a period of at least two years from the date that a rider complaint is received by the TNC.
