This semitruck slid off the icy road on a curve just south of Hebron along Rt. 47. The driver was not hurt. The McHenry County Sheriff's Office has been advising drivers all day to avoid traveling if possible. Rural county roads have been experiencing refreezing even after several passes by salt trucks.
