Anaconda-Deer Lodge County commissioners have approved a ban on talking on cellphones while driving unless you're using a hands-free device.

Commissioners voted 3-1 Tuesday to expand a driving-while-texting ban that was passed two years ago. Both ordinances were proposed by eighth grade honors U.S. history students at Fred Moodry Middle School.

Police Chief Tim Barkell says officers haven't issued a single citation since the texting ban went into effect, but Assistant Chief Bill Sather told commissioners the department will do its best to enforce the law.

In Great Falls, city commissioners are considering banning drivers from texting and talking on cellphones without a hands-free device. The Great Falls Tribune reports a proposed ordinance is expected to go to a first reading on June 19.
