Talk show host Oprah Winfrey is on a new mission to stop drivers from using cell phones while on the road.
Winfrey took her cell phone campaign nationwide, Friday, declaring it "No Phone Zone Day."
Thirty states are participating in the No Phone Zone campaign. Supporters put signs on highways and spread the world through social networking and the media.
Statistics show 16 percent of all fatal crashes in 2009 involved distracted drivers.
Winfrey wants people to sign a pledge vowing to stop using phones while on the road -- both texting and talking.
More than 200,000 people have already taken the No Phone Zone pledge, including many celebrities that have appeared on Winfrey's show.
