D.C. Code § 50-301.30: Vehicle inspection officers.

(a)

Vehicle inspection officers shall undergo training on the rules and regulations governing private and public vehicles-for-hire and carrier-for-hire vehicles and undergo yearly performance evaluations. Vehicle inspection officers shall be prohibited from making traffic stops of on-duty private or public vehicles-for-hire in the act of transporting a fare and carrier-for-hire vehicles in the act of transporting a parcel, food, or beverage, unless there is reasonable suspicion of a violation, and shall act in accordance with all rules governing their duties, as established through rulemaking.

(b)

Upon reasonable suspicion of an illegal street hail, a public or private vehicle-for-hire operator shall provide a law enforcement official or vehicle inspection officer with access to a device containing an electronic record of trips sufficient to establish that the ride in question was prearranged through digital dispatch. Failure to have or provide access to a device containing such a record shall constitute a civil infraction punishable by fine or other penalty as established by the Mayor; provided, that an operator shall not be required to relinquish custody of a device containing evidence of a trip arranged through digital dispatch.
