As of July 1, 2015 it shall be a violation to use a cell phone while driving unless it is Bluetooth enabled, or a hands-free device that is integrated into the vehicle.
RSA 265:79-c provides very few exceptions to this prohibition: (1) if the person is behind the wheel and the vehicle is pulled to the side of, or off the road at a location where it is legal to do so and the vehicle remains stationary; (2) if the person is calling 911 to report an emergency; and (3) if the person is using one hand to transmit or receive messages on any non-cellular 2-way radio.
A first offense carries a fine of $100 plus penalty assessment; a second offense is $250 and any subsequent offenses carry a fine of $500. Additionally, if the driver is under 18 she is subject to a loss of license pursuant to RSA 263:14, III.
A police officer may pull you over solely for violating this new law and if a police officer sees you holding a phone to your ear he will presume you are making a call.
