While New Hampshire currently does not have a law specifically against the use of cell phones while driving, driving impaired by the distraction of cell phone use would violate the law against reckless driving (NH Rev. Stat. Sec. 265:79). The minimum fine for reckless driving is $250.
A motorist who uses two hands to type a text message or operate an electronic telecommunications device while driving violates the law (NH Rev. Stat. Sec. 265:105-a).
Entering a phone number or an address into a cell phone or global positioning system is not considered a violation of this law.
The viewing of television broadcasts or dynamic visual images from digital video equipment or image display devices while driving is prohibited (NH Rev. Stat. Sec. 266:75 ). This law does not apply to image display devices that provide navigation or traffic and/or road conditions or that face rearward toward passengers.
