Section 21655.6 of the Vehicle Code. If the arrest for a violation of either

Section 21655.5 or 21655.8 of the Vehicle Code was not within a city, then percent of the fines and forfeitures shall be transferred to the general fund of the county and percent shall be transferred to the agency having authority to approve high-occupancy vehicle lanes pursuant to

In counties where there exists a county transportation commission created pursuant to Division 12 (commencing with

Section 130000) of the Public Utilities Code, that commission is the agency for purposes of this section.
