Cell Phones and Driving

In the era before cell phones, I rear ended a range while adjusting the heater.

I'll use the phone on the highway in minimal traffic, or on extremely familiar roads, but generally try not to.

Missouri has no such phone laws for adults yet, but burden of proof is supposed to be on the state.

That said, I feel that they probably wager the cost of the ticket isn't worth your time. Providing a phone bill showing lack of operation at time and date on ticket should be sufficient, especially if you use your phone for music.
