Newly installed road sign reflectors alert drivers that surface is frozen

CLARKSTON, WA – The cold front sweeping down from Canada has thermometers still well-below freezing temperatures. To get drivers to slow down the Asotin County Public Works Department recently installed these handy reflectors. They turn blue when the area gets below freezing. A few have been installed around the county near steep grades, like this one at the bottom of Critchfield Road.
