Today President Obama signed an executive order that prohibits employees of the federal government from sending text messages while driving a government vehicle, when using a government-issued device in their own vehicle, or when driving on official government business. The government also plans to ban truck drivers from using cell phones while driving, which includes texting and placing voice calls. Cell phone use will be permitted only during emergencies. The ban goes into effect immediately for government workers, but the ban for truck drivers needs to be enacted into law first. The idea is to make roads in the U.S. safer by forcing government and truck drivers to pay attention to the task of driving, rather than using their cell phones.
