    What is Distracted Driving?*

     • Three types of driver distractions
         – Visual – taking your eyes off the road
         – Manual – taking your hands off the wheel
         – Cognitive – taking your mind off the drive

          “Eyes on road, hands on
          wheel, mind on drive”


     • Risk, attention and “multitasking”
