Traffic control devices in work zones.
The traffic control plans contained in this booklet are furnished as a guide to be used along with good judgment. Minor modifications may be made, as necessary, to accommodate site conditions; however, a plan's original intent must be maintained. An alternate plan should be considered if substantial revisions are needed.
Slow down – lives are on the line.
In 2022, speeding continued to be a top reason for work zone crashes.
Even one life lost is too many.
Each year about 670 people are killed nationally in highway work zones. In 2022, Washington had six 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.
