Cell phones while driving?

Apparently, there is a law that could be passed in Colorado about how you might not be able to use a hand held cell phone while driving. I think that this is a good law for Colorado, because so many people are crashing here that we really do need to do something about it. They also said that they might ban hands-free devices too, and I agree with it. Some people think that having one hand on the phone is the reason for accidents, but it is really not paying attention to the road and paying attention to the conversation that you are having. Overall, I think they should ban cellular DEVICES in cars, because it is the reason for so many car accidents.
