It's now illegal to text and drive in more than 40 states across the country and the penalties for breaking the law are increasingly stiff.

Might Ohio be leading the way?
When officers there arrive at the scene of a serious crash, they consider cell phones potential evidence and are trained to obtain the devices, either with the drivers consent or with a warrant.

Some say this is an invasion of privacy, but Ohio State Highway Patrol maintains it's a necessary step.
