Are you familiar with the new cellphone law in Tennessee?

A new cellphone law was just recently enacted for the people in Tennessee. I predict that no one will be cited or arrested for violating this law. Why? It’s too hard to enforce. You can still talk on a cellphone, while driving, but texting is now illegal. How can an officer tell the difference between someone punching in numbers to make a phone call, compared to someone punching in letters for a text message? Unless the officer is riding in the same vehicle and observes this, there is no way to tell the difference. Question: Did the lawmakers, in Tennesee, stop short of enacting a cellphone safety law that had some teeth in it or was this just a “window dressing” law that will never be enforced?
