Adding supplemental traffic control devices upstream of flagger stations has the potential to increase conspicuity and alert drivers that they are approaching a work site. These additional devices are very low in cost, and are easily deployed. The attached drawing shows a typical layout for a flagger station. Actual distances will vary to meet approach speeds and roadway conditions, and minor adjustments should be made as necessary to achieve the best results.

Use Guidelines
  • Additional cones and an FS-1 flag tree are to be used upstream of flagger stations to provide added warning to drivers.
  • These devices are to be used for flagger stations on all Department operations except those that are constantly moving, or are in use at one location for no more than a few minutes. If the W8-22 Flagger sign is used, the additional cones and flag tree are also to be used.
  • Notes requiring the enhanced setups are to be added to upcoming projects beginning in August, using amendments if necessary.
Completion Date

Upstream cones and flag trees should be in place at flagger stations no later than June 15.

Reporting Requirements

By June 15, each Region is to confirm that this countermeasure is in place on construction and maintenance sites.
