The NHTSA recently estimated that at least 6% of drivers use their mobile phone (without a hands-free device) at length while they are driving and that at least 11% of drivers speak at length on their telephones while using a hands-free device like Blue Tooth. The NHTSA says that whether it's hand-held or hands-free, talking on your phone while driving distracts drivers enough to cause lapses in judgment and sometimes complete disregard for what is going on around them. It is estimated that about 800,000 people are driving and talking on their mobile phones at any given time of the day.
