　　You aren't supposed to use your cellphone while driving.You already know this, but you still do it sometimes just like I did in the past.In Illinois, drivers are required to be "hand­free"．But it is really tough to be truly "hand­free" when it comes to using a cellphone in the car.

　　Here is what I did in the past.When my phone rang, I answered and quickly asked the caller to hold on for a minute.Then I put my earphones in, asked the caller, "Can you hear me？" and then began the conversation.

　　I recently learned that I had been doing my "hand­free" driving all wrong.A few weeks ago, I attended a dinner hosted by Jabra, a Danish company that makes Bluetooth devices.I eagerly accepted the invitation because I had very little understanding of Bluetooth technology and thought that maybe I would learn more about how expensive it would be to have it installed in my car. Instead, I learned that anyone can have Bluetooth technology in his or her car for about $ 60.You don't have to have a system installed.You just buy a very small device, pair it with your phone and you are set to go.With it, you can make, answer, conduct phone calls truly hand­free in your vehicle.When I lost the set of earphones that I had been using a few months ago, I paid about $ 30 to replace them.If only I had known then that for only$ 30 more, I could have a_safer_solution.

　　Now I am feeling so much better about talking by phone while driving.I want to share this information with you to tell you that you can make driving safer for about $ 60.Totally worth it.

　　Nevertheless, it is very dangerous to talk over the phone while driving no matter whether you are using a hand­held cellphone, earphones or Bluetooth devices.Avoid doing it!
