If you are traveling over the Thanksgiving weekend, road conditions will be certainly be of great concern. Sometimes only trace amounts of either freezing rain or snow is necessary to make travel hazardous. One service that has greatly helped travelers has been the introduction of the 511 service that most states now use, including all the states in the upper-Midwest.
You simply dial 511 from any phone (including your cell phone), follow a few simple directions and you will be given the latest available road conditions for the area you selected. This service originated in this area. The University of North Dakota started the #SAFE program in the winter of 1996. That program was used as the basis of the national 511 system that is currently in place. Road conditions can change rapidly, but usually this service can give you a good estimate to the conditions you will be experiencing during your travels.
