California Code, Vehicle Code - VEH § 9400.7

(a) Notwithstanding any other provision of law, except for restrictions in existence on June 1, 1989, and except as provided in subdivision (d), so long as any increases in the weight fees required by Section 9400, as enacted by Assembly Bill 471 of the 1989-90 Regular Session, remain in effect, no local agency located within an urbanized area within a county which is required to prepare a congestion management plan pursuant to Section 65089 of the Government Code may restrict the hours of operation on any street or highway which is otherwise open to truck use unless the local agency determines that the restriction is consistent with the adopted congestion management plan and is coordinated with adjacent local agencies so as to not unreasonably interfere with truck operations.

(b) If an inconsistency in access occurs between cities and counties, the inconsistent access provisions of the congestion management plan may be appealed to the California Transportation Commission.  The commission shall review the inconsistent access plan and make a finding within 90 days of the appeal being filed.  If the commission fails to make a finding within 90 days, the Director of Transportation shall review the issue and make a finding within 30 days.

(c) The access provisions of the congestion management plan shall not go into effect while an appeal is being made.  If the commission makes a finding of inconsistency, the access provisions of the congestion management plan shall not become operative.
