text: An sort good option would be to use speaker phone. However, this option is not completely hands free, as it requires the driver to either make an call or answer one. Another option would be to install a phone service available in newer vehicles such as OnStar. To use this option the driver must say the phone number or store the name of the contact you want to call. Which could still be distracting to a driver trying to remember a phone number, rather than concentrating on the road. So no matter how your talking on the phone hands free or not it's never ok to be on your phone while driving.
