Don't know how this would work. Do we tell doctors to not take calls, how about police that have not only a radio but a phone and a laptop in the front seat.
What about businesses that use two way communication to direct their employees to jobs.
I would think that thousands of people trying to get to the side of the road to take a call is going to kill as many people as we have now. The new accidents will be the people rushing to make up time lost by pulling over to the side of the road. Some places, like big urban areas have no place to pull over to take a call. People will find ways around this and if they don't they will die in the crash running a stop sign or light trying to make up the time.

I would think a couple of kids in the back seat are more distracting than a cell phone.
Now I have cussed my share of people who text and have a phone on their ear making it impossible for them to get to their turn signal switch but to make hands free against the law is BS.

It is ammazing how they will be able to get this fast tracked and passed while the real work of running our country goes down the crapper!

THROW THEM OUT. They are the most useles 535 people we have on the planet right now. I hope they don't let this kind of crap coming from NTSB get to a vote.
Maybe they should take a page from Al qaeda and change their name so the might get a better image.
