Texting while driving, also called texting and driving, is the act of composing, sending, reading text messages, email, or making similar use of the web on a mobile phone while operating a motor vehicle. Texting while driving is considered extremely dangerous by many people, including authorities, and in some places have either been outlawed or restricted. A survey of more than 90 teens from more than 26 high schools throughout the United States conducted by Liberty Mutual Insurance Group in 2006 showed that 46% of students consider texting to be either "very" or "extremely" distracting. An American Automobile Association study showed that 34% of teens (age 16–17) admitted to being distracted behind the wheel because of texting and 40% of American teens say they have been in a car when the driver used a cell phone in a way that put people in danger. A study involving commercial vehicle operators conducted in September 2009 concluded that though incidence of texting within their dataset was low, texting while driving increased the risk of accident significantly.
