Usage & Applications

Auto flaggers are useful during times of maintenance when one-way traffic is required. Some common applications include working on roads, guardrails, sewers, trees, gas lines, etc. Most of these tasks require large equipment that takes up a lane of the road.

When a road becomes one-way, there need to be traffic signals to alert traffic when to wait and when to proceed with caution. AFAD can autonomously control the flow of traffic through one-way zones and keeps workers out of danger’s way.

Benefits of Using AFADs

AFADs effectively grab the attention of drivers and communicate exactly when to come to a stop. The device can be set up on the side of the road where it is not in the way of traffic, which is why the caution arm lowers to provide a visual and physical barrier for drivers to see. This makes it safe for the AFAD and safe for the operator by keeping them out of the road.

Another benefit of these devices is that they are extremely simple to operate, and any worker can learn how to use them. With a fast setup, a simple control system, and safer traffic control, there is no reason why you shouldn’t implement an AFAD into your construction operations.


We have a fleet of John Thomas Inc. portable signals and related accessories available for sale or rent.
