HCR Update from Mark Sanna: A new study in the New England Journal of Medicine found that an inexperienced driver who reaches for a cell phone increases the risk for a crash by more than 700%. Among teenagers, eating almost tripled the risk for a crash, and texting or looking at an object on the side of the road quadrupled it. Dialing a phone was the most dangerous activity of all, resulting in eight times the risk for a crash or near-crash.
