CA Truck Network
The color-coded "California Truck Network" for State highways is the official government source for truck route information. There are many private truck route guides, e.g., the Rand McNally Motor Carrier Atlas and various GPS systems. However, the accuracy of those private guides cannot be guaranteed, and must be verified by consulting the official "California Truck Network," which could be found in QuickMap under the Commercial Vehicle Options. Where inaccessibility to internet is expected during travel, one may choose to print PDF versions of the California Truck Network maps, accessible by clicking on the number 1-12 following District Maps (PDF) below. The table at the bottom of the page shows which color routes on the map your truck may legally travel on.
