This video is an adaptation of a scenario from CCJ’s Preventable or Not manual. It is presented via a partnership between CCJ and Instructional Technologies. While exiting a grocery store after delivering a load, John Doe’s tractor struck a dock door that had been partially lowered while he was inside the store. Was this a preventable crash?
