More than 112 million Americans use wireless phones. An estimated 85 percent of them use phones while driving. Still, there aren't many studies that detail the link between accidents and talking while driving.

"Why would anyone want to take a chance?" Sinclair asked. "The best thing is just not to talk while on the road."
