(Olympia, WA) -- Washington Governor Jay Inslee has signed bill that aims to protect workers on state highways. The Washington legislature passed the bill with unanimous support. It allows speed safety cameras to be used in state highway work zones. In 2021, there were 283 minor injury crashes, 28 serious injury crashes and five fatal crashes in work zones. Distracted driving, following too close, and speeding were the main causes of the crashes. The goal is to get drivers to slow down and pay more attention in work zones. It takes effect in June of 2024.
