N.H. Rev. Stat. Ann. § 264:15
I. Except as provided in paragraph I-a, no policy shall be issued under the provisions of RSA 264:14, with respect to a vehicle registered or principally garaged in this state, unless coverage is provided therein or supplemental thereto at least in amounts and limits prescribed for bodily injury or death for a liability policy under this chapter, for the protection of persons insured thereunder who are legally entitled to recover damages from owners or drivers of uninsured motor vehicles, and hit-and-run vehicles because of bodily injury, sickness, or disease, including death resulting therefrom. When an insured elects to purchase liability insurance in an amount greater than the minimum coverage required by RSA 259:61, the insured's uninsured motorist coverage shall automatically be equal in amounts and limits to the liability coverage elected. For the purposes of this paragraph umbrella or excess policies that provide excess limits to policies described in RSA 259:61 shall also provide uninsured motorist coverage equal to the limits of liability purchased, unless the named insured rejects such coverage in writing. Rejection of such coverage by a named insured shall constitute a rejection of coverage by all insureds, shall apply to all vehicles then or thereafter eligible to be covered under the policy, and shall remain effective upon policy amendment or renewal, unless the named insured requests such coverage in writing.
I-a. No commercial motor vehicle liability policy issued under the provisions of RSA 264:14 shall be required to provide coverage for motor vehicles that are not owned by the policyholder for the protection of persons insured thereunder who are legally entitled to recover damages from owners or drivers of uninsured motor vehicles, and hit-and-run vehicles because of bodily injury, sickness, or disease, including death resulting therefrom.
V. Every document tendered to settle a claim for bodily injury which may be the subject of coverage under this section shall prominently contain the following language, which shall be read and signed by the releasing party or parties:
