California Code, Business and Professions Code - BPC § 7460

(a) A network company shall institute a “zero tolerance policy” that mandates prompt suspension of an app-based driver's access to the network company's online-enabled application or platform in any instance in which the network company receives a report through its online-enabled application or platform, or by any other company-approved method, from any person who reasonably suspects the app-based driver is under the influence of drugs or alcohol while providing rideshare services or delivery services.

(b) Upon receiving a report described in subdivision (a), a network company shall promptly suspend the app-based driver from the company's online-enabled application or platform for further investigation.

(c) A network company may suspend access to the network company's online-enabled application or platform for any app-based driver or customer found to be reporting an alleged violation of a zero tolerance policy as described in subdivision (a) where that driver or customer knows the report to be unfounded or based the report on an intent to inappropriately deny a driver access to the online-enabled application or platform.
