Seattle Department of Transportation wants you to slow down! Seattle’s transportation director has been working with city council on a plan to reduce the speed limit in Seattle by 5 mph. They say 42% of all fatality collisions can be attributed to speed. The changes would ultimately impact 2,400 miles of roadways, both residential and downtown. It will most likely be taking effect in November, as part of the city’s Vision Zero initiative, hoping to end traffic deaths and serious injuries by 2030.
