It seems like a pretty reasonable rule: When you are driving, stay off of your cell phone.
After all, there is enough to do already. There are the physical and mental demands of operating a vehicle, combined with the extracurricular activities of finding a decent tune on the radio, checking the time, adjusting the temperature, making sure your hair looks all right in the rear-view mirror, and perhaps attempting to have a conversation with a passenger, to name a few.
It’s a logical conclusion that another activity, such as dialing and talking to somebody on a phone, is not needed.
