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.
