LANSING, Mich. -

Michigan Gov. Rick Snyder signed legislation Tuesday which prohibits novice drivers from using a cell phone while behind the wheel.

Watch: Local 4 puts hidden camera in teen’s car.

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.
