HELENA, Mont. (AP) — State lawmakers are considering telling Montanans to hang up and drive — or face hefty fines.

Sen. Christine Kaufmann, D-Helena, told the Senate Highways and Transportation Committee on Tuesday that Senate Bill 390 would allow drivers to talk on their cellphones only through a hands-free device. Under Kaufmann’s measure, minors behind the wheel wouldn’t be able to speak on cellphones at all, and no driver would be allowed to text while driving.
