Roads throughout Central Oregon will continue to be slick throughout the holidays. ODOT officials are asking you to drive slower and not get over-confident; even if you have studs or four-wheel drive. Rick Williams with ODOT says even with road crews trying to make the highways safer, there is only so much they can do. Mother Nature usually prevails: “What's typical for Central Oregon: it warms up during the day, a little layer melts on top, then around 3 to 5 starts to refreeze right in time for the evening commute. Then it gets pretty tricky. You get a mixture of heavy truck traffic and cars mixing together; places like Lava Butte or up in Cow Canyon, north of Madras, it makes for some pretty tricky driving." Williams says one problem they are seeing is that when they put de-icing materials on the road to make it safer; then people drive about 15 miles an hour faster which is usually too fast for the slick conditions. Rick Williams was on the KBND Morning News Program "Your Town" this morning.
