California Truck Network Map


The color-coded "CaliforniaTruck Network Map" 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 "Caltrans Truck Network Map."  The table at the bottom of the page shows which color routes on the map your truck may legally travel on.
