Me. Stat. tit. 24-A § 2902-F
An insurer may not refuse to issue motor vehicle liability insurance to an applicant solely because the applicant is a volunteer driver. An insurer may not impose a surcharge or otherwise increase the rate for a motor vehicle policy solely on the basis that the named insured, a member of the insured's household or a person who customarily operates the insured's vehicle is a volunteer driver. For purposes of this section, "volunteer driver" means a person who provides services, including transporting individuals or goods, without compensation above expenses to a nonprofit agency or charitable organization as defined in Title 14, section 158-A. This section does not prohibit an insurer from refusing to renew, imposing a surcharge or otherwise raising the rate for a motor vehicle liability insurance policy based upon factors other than the volunteer status of the insured driver. [1995, c. 132, §1(NEW).]
