This would include:
texting....duh!
holding a phone to your ear.
dialing out* you can only dial out using hot keys. ie 1 = office. 2 = wife/husband. etc.
simply having a blue tooth headset will not be sufficient. You can still be pulled over for scrolling through your address book to dial a number.
That said, I've done some research I thought I might share to help all of us here be as safe as possible...even if a similar law hasn't found your juristiction yet.
As I have come to understand in my research, most voice recognition enable phones don't work very well (blackberry).
There is a free application called Vlingo. You can also pay a one time price of $18.00 for the plus version which will allow you to dictate emails as well. It is intuitive and learns your speech as you go. It understands human language, not computer language....so umming won't throw it off track and you don't have to memorize certain commands for specific functions.
Everything I've seen about this is glowing. If anyone has experience with it, or has something to add, I would love to hear it.
