COLUMBIA, S.C. - Miss South Carolina Brooke Mosteller has thrown her tiara into the political ring.

Following in the footsteps of her uncle, Sen. Chip Campsen of the Isle of Palms, Mosteller joined scores of pageant contestants at the Statehouse on Wednesday to urge lawmakers to ban texting-while-driving.

Mosteller says texting is six times more dangerous than drunk driving and is the leading cause of death for American teens.

The House and Senate have passed differing versions of the ban.

The House version would impose a $25 fine for drivers caught handling cellphones but would prohibit police from viewing the phones. The legislation is in response to confusion created by local governments enacting varying bans.

South Carolina and Montana are the last states that do not to have laws against texting while driving.
