Clayton Municipal Code Ch. 10.28 Vehicle Weight Limits

Whenever any ordinance of this city designates and describes any street or portion thereof as a street, the use of which is permitted by any registered commercial motor vehicle exceeding a gross vehicle weight (GVW) of 10,000 pounds (five (5) tons), the Director of the responsible City Department or his/her designee is hereby authorized to designate such street or streets by appropriate signs as "truck routed" for the movement of registered commercial motor vehicles exceeding a GVW of five (5) tons. Commercial motor vehicles registered by the California Department of Motor Vehicles (DMV) according to the Commercial Vehicle Registration Act (CVRA) are issued CVRA weight decals and year stickers that must be displayed on both the right and left sides of the vehicle for enforcement identification.

When any such truck route or routes are established and designated by appropriate signs, the operator of any registered commercial motor vehicle exceeding a GVW of five (5) tons shall drive on such route or routes and none other, except when necessary to traverse another street or streets to a designation for the purpose of loading or unloading, but then only by such deviation from the nearest truck route as is reasonably necessary. This subsection shall not be construed to relieve an operator subject to this section from obtaining an encroachment permit pursuant to Chapter 12.04 if applicable.

The provisions of this section shall not apply to: (1) passenger buses under the jurisdiction of the Public Utilities Commission, (2) any vehicle owned by a public utility while necessarily in use in the construction, installation, or repair of any public utility, or (3) refuse collection vehicles which operate on city streets pursuant to provisions of Chapter 8.04.

Those streets and parts of streets established by ordinance of the Council are hereby declared to be truck routes for the movement of registered commercial motor vehicles exceeding a GVW of five (5) tons.
