Serious injuries occur because a driver's speed exceeded the vehicle's ability to provide protection. Distracted driving is any activity that diverts the attention from driving, including talking or texting on the phone, eating and drinking, talking to people in the vehicle, fiddling with the stereo, among other distractions.
