Back in January, one Upper Peninsula mom’s hard work from the last two years paid off in a big way. Governor Rick Snyder signed "Kelsey's Law" into while Bonnie Raffaele looked on. Bonnie, whose daughter Kelsey was tragically killed in an accident in 2010, has been very outspoken in her efforts to get cell phone use banned by teen drivers. The law, which affects teen drivers in Michigan, prohibits the use of cell phones while driving and takes effect Thursday. I had a chance to talk to Bonnie back in January about Kelsey’s Law and what it means to her. Check out the interview after the jump.
