This book was created to be used for training the flagger to work safely and to protect the safety of others.

Flaggers are a vital role in the successful operations of all maintenance, construction, and utility projects. Flaggers shall need to know the information within this book well enough that it becomes second nature.

Flaggers are required when all other methods of traffic control are not enough to control the situation, and the impacts of the temporary traffic control zone.

Your fellow workers and the road users depend on your ability to stay alert while controlling traffic using your visual movements along with your “Stop/Slow” paddle.

As a flagger the actions you take reflect on yourself as well as your employer. You are often the initial point of contact the traveling public will have with the work zone.

While performing your flagging duties you shall be efficient, responsible, and conducting yourself in a safe and professional manner at all times.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
