Your Guide to Getting the C-31 Construction Zone Traffic Control License in California!
Thinking about becoming a licensed Construction Zone Traffic Control contractor in California? The C-31 license allows you to legally handle crucial work like setting up lane closures, flagging, and managing traffic with devices like cones and arrow trailers on public roads and highways. This is your first step toward a successful career with greater earning potential.
To qualify, you must be at least 18 years old, have a Social Security or ITIN number, and—most critically—prove four years of journeyman-level experience in C-31 work.
