PUC §5411.5: (a) Whenever a peace officer, as defined in Chapter 4.

(a) Whenever a peace officer, as defined in Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code, arrests a person for operation of a charter-party carrier of passengers without a valid certificate or permit, the peace officer may impound and retain possession of the vehicle. (b) Whenever a peace officer, as defined in Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code, arrests a person for operating a charter-party carrier of passengers as a taxicab in violation of an ordinance or resolution of a city, county, or city and county, the peace officer may impound and retain possession of the vehicle. (c) If the vehicle is seized from a person who is not the owner of the vehicle, the impounding authority shall immediately give notice to the owner by first-class mail. (d) The vehicle shall immediately be returned to the owner if the infraction or violation is not prosecuted or is dismissed, the owner is found not guilty of the offense, or it is determined that the vehicle was used in violation of Section 5411 without the knowledge and consent of the owner. The vehicle shall be returned to the owner upon payment of any fine ordered by the court. If the vehicle is seized due to a violation of a person other than the owner of the vehicle, the vehicle shall be returned to the owner after all impoundment fees are paid. After the expiration of six weeks from the final disposition of the criminal case, unless the owner is in the process of making payments to the court, the impounding authority may deal with the vehicle as lost or abandoned property under Section 1411 of the Penal Code. (e) At any time, a person may make a motion in superior court for the immediate return of the vehicle on the ground that there was no probable cause to seize it or that there is some other good cause, as determined by the court, for the return of the vehicle. A proceeding under this section is a limited civil case. (f) No peace officer, however, may impound any vehicle owned or operated by a nonprofit organization exempt from taxation pursuant to Section 501(c)(3) of the Internal Revenue Code which serves youth or senior citizens and provides transportation incidental to its programs or services or a rented motor vehicle that is being operated by a hired driver of a charter-party carrier of passengers that is providing hired driver service.
