[ screaming ] reporter and this morning, new evidence that not only is distracted driving a major factor behind car crashes, but that the risk of crashing rises significantly when drivers were emotional angry, sad, tearful or agitated. The study conducted by the Virginia TechTransportation Institute surveyed 3,500 drivers between the ages of 16 and 98 through a threeyear period. Distractions that take a drivers eye away from the road for an extended period of time create the greatest crash risk. The most common being reaching for a cell phone, reading or writing or using touchscreen menus on the dashboard. The lead author of this study says these findings are particularly useful because they show just how distracted teens were while driving. He says if something isnt done soon to limit the distractions there could be scary results in the future. Also looking on the dashboard too.
