Michigan Gov. Rick Snyder signed legislation Tuesday which prohibits novice drivers from using a cell phone while behind the wheel.
The legislation applies to holders of Level 1 licenses, who must be accompanied by a parent, guardian or another licensed driver at least 21 years old, and those with Level 2 licenses, who can drive alone with some limits on hours and carrying young passengers.
It exempts Level 3 drivers, who have full privileges.
Snyder was joined at the bill signing by family members of Kelsey Raffaele, a 17-year-old from the Upper Peninsula who was killed in a crash while chatting on her cell phone.
Kelsey died in January 2010 near her home in Sault Ste. Marie.
Bonnie Raffaele, her grieving mom pushed for "Kelsey's Law."
Raffaele has previously said her focus is on inexperienced teens, who are especially vulnerable.
