Guidance on the Use of Automated Flagger Assistance Devices

Automated flagger assistance devices (AFADs) are mechanically operated temporary traffic control devices that function under the same operational principles as traditional flagging. AFADs are considered a safety enhancement because they minimize flaggers direct exposure to traffic by allowing them to control the flagging device from an area away from traffic, such as behind a guardrail. As a result, the AFAD increases worker safety compared to traditional flagging methods. It is important to recognize that AFADs do not eliminate the need for qualified flaggers at the work zone. This document details the appropriate use of AFADs.
