The Truck Network feature class is a line feature class representing State truck route segments and their truck access designations (such as National Network, Terminal Access, California Legal, Advisory, or Restricted) with each segment's beginning and ending postmiles, and beginning and ending cross streets.

The truck network routes were identified and extracted from State Highway Network based on the California "Truck Network" Route List (Division of Traffic Operations, Office of Commercial Vehicle Operations, Legal Truck Access Branch).
