A Huntsville ISD bus which was traveling down FM 1791 in far north Montgomery County came upon a curve. After a tire slipped off the pavement the driver overcorrected, crossed the roadway and climbed the embankment on the opposite side of the road. The bus then rolled. Twenty-three were transported to the hospital, 10 by ambulance and 13 by a school bus with paramedics aboard. All went to Conroe Regional Hospital, all with minor injuries. DPS and Huntsville Police are investigating.
