What is Flagging in Construction?

Flagging | April 28, 2020

Understanding what flagging is in construction will provide you with a better idea of how construction sites on roadways operate. At Valley Traffic Systems, we understand the important role a traffic control person (TCP) plays in creating a safe working environment. That is why we offer training services for TCPs.

What do Flaggers do?

TCPs are the people on construction sites who control the traffic along roadways and highways to help keep traffic flowing through the construction zone. TCPs work together to get all directions of traffic through the job site safely and efficiently. TCPs are also responsible for putting out traffic control devices, such as cones and signs, as well as communicating with motorists.

Flagger Duties and Responsibilities

While a TCP’s duties and responsibilities will vary, depending on their employer, there are several core tasks common to all TCPs, including:

Direct Vehicles

By using hand signals and large direction signs to tell drivers when to stop or proceed slowly, TCPs can easily direct traffic safely through a construction site. TCPs may also be able to answer any questions motorists have about detours caused by the construction.

Communicate with Other TCPs & Construction Personnel

TCPs often use radios to communicate with other TCPs positioned at different spots along the construction site in order to safely coordinate two-way traffic on a single-lane road and notify each other if the job site changes in any way. TCPs may also need to alert members of the construction crew to any traffic concerns that might impact their work or safety.

Place Traffic Cones & Construction Signs

Before construction can begin each day, TCPs will set up traffic devices and signs at and around the road construction site, including detour signs, road work ahead signs, end of road work signs, and road closure signs. At the end of the workday, TCPs will be responsible for retrieving all of the devices and signs as directed.

Record Information

TCPs are responsible for observing and recording any details about drivers who fail to obey speed limits, construction signs, or other directions provided by the TCPs. This information is often submitted to the site supervisor or, in some cases, law enforcement officers.
