California – Flagger Certification Training Course©
(Minimum 4 hours) – This training meets certified flagger requirements for Caltrans contracts


This course is an introduction to the basic principles of work zone flagging as outlined in the Cal/OSHA, Construction Safety Orders: 1599(f) and 1599(g). This 4 hour training course is designed to provide hands-on instruction as well as instruct the student on the basic fundamentals of traffic control work zone flagging, in accordance with the current California Manual on Uniform Traffic Controls Devices (CA MUTCD).

This course will enable the student to apply practical concepts and provide the student with the practical knowledge needed to satisfy Cal/OSHA’s requirements. Students are required to complete a written examination and demonstrate the basic skills of flagging. Students who successfully pass the written and in-person exam will receive a “Certified Flagger” Card issued by ATSSA and become searchable on ATSSA’s website.
