SALT LAKE CITY -- The dangers of texting while driving might seem obvious, but for anyone who doesn't get it, state officials are releasing a 15-minute public-service DVD. The Utah Department of Transportation held a news conference Wednesday to promote the video documentary on an accident that killed two people when a driver who was texting collided with another vehicle. For drivers, texting or sending e-mails from a cell phone became a Utah misdemeanor in May. The documentary was part of a sentencing agreement with the 22-year-old man, who pleaded guilty in January to two counts of negligent homicide. Prosecutors say the driver was thumbing out a text message when his SUV clipped the bumper of a car, which went out of control and was broadsided by a pickup in September.
