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.

So what does Kelsey's Law mean for teens? Any driver with a Level 1 or 2 driver's license will be banned from using hand-held cellphones while driving. No texting, no calling. As of now, the law applies to teens only, but if Michigan follows in the footsteps of some other states, cell use by adults could eventually become against the law as well. Violation of the law will not be a moving violation, but it will be a civil infraction and the violator could face a fine, and their probationary license time could be extended for another six months.

Teens will still be able to use their cellphones to report emergencies, and if they drive a car with On-Star or some other type of integrated phone system, they will be allowed to use that as well.
