Unfortunately laws are written to mandate common sense. There must have been fatalities in order for this law to be written.
My neighbor got in a serious accident over the summer because the teenage driver was texting his friend and dropped his phone. When he picked it up to retrieve it he ran head-on into my neighbor's car. He is the father of six children and was nearly killed.
I don't think you'd want that happening to you, and if someone was idiot enough to be texting his friend instead of focusing on the road, you'd have his head yourself, guaranteed.
It's shame that laws like this have to be written because people have no common sense and think they can just do what they want when they want with no sense of accountability at all.
It did just happen to me! My two youngest daughters were riding to school at the beginning of this school year on the school bus, when the driver in the truck following was busy texting. She ran into the back of the bus sending both my daughters to the ER via ambulance, as well as six other students!
I did not call my state rep and ask for a law to be written, I spoke with the seven cops and three ambulance crews and demanded that the driver be given tickets for unsafe operation in a school zone! And she was given three tickets that day (including unsafe operation of a motor vehicle)!
