Discription of Events: On E/B I-70 through Howard County MD - speeding > than 85 mph, darting in & out of cars, tailgating almost caused 2 accidents. Highly erratic driving. ***MAIN REASON WHY I AM REPORTING THIS IS THAT THERE WERE SEVERAL YOUNG CHILDREN IN THE BACK -either 2 or 3 kids- & THEY WERE LOOKING TERRIFIED.*** I am not sure if those kids were mean to be in that car. The car was driving so erratically that I thought this could be a possible kidnapping.
