Sec. 2111.

    (1) Notwithstanding any provision of this act or this chapter to the contrary, classifications and territorial base rates used by an insurer in this state with respect to automobile insurance or home insurance must conform to the applicable requirements of this section.

    (2) Classifications established under this section for automobile insurance must be based only on 1 or more of the following factors, which must be applied by an insurer on a uniform basis throughout this state:

    (a) With respect to all automobile insurance coverages:

    (i) Either the age of the driver; the length of driving experience; or the number of years licensed to operate a motor vehicle.

    (ii) Driver primacy, based on the proportionate use of each vehicle insured under the policy by individual drivers insured or to be insured under the policy.

    (iii) Average miles driven weekly, annually, or both.

    (iv) Type of use, such as business, farm, or pleasure use.

    (v) Vehicle characteristics, features, and options, such as engine displacement, ability of the vehicle and its equipment to protect passengers from injury, and other similar items, including vehicle make and model.

    (vi) Daily or weekly commuting mileage.

    (vii) Number of cars insured by the insurer or number of licensed operators in the household. However, number of licensed operators must not be used as an indirect measure of marital status.

    (viii) Amount of insurance.

    (b) In addition to the factors prescribed in subdivision (a), with respect to personal protection insurance coverage:

    (i) Earned income.

    (ii) Number of dependents of income earners insured under the policy.

    (iv) Use of a safety belt.

    (c) In addition to the factors prescribed in subdivision (a), with respect to collision and comprehensive coverages:

    (i) The anticipated cost of vehicle repairs or replacement, which may be measured by age, price, cost new, or value of the insured automobile, and other factors directly relating to that anticipated cost.

    (ii) Vehicle make and model.

    (iii) Vehicle design characteristics related to vehicle damageability.

    (iv) Vehicle characteristics relating to automobile theft prevention devices.

    (d) With respect to all automobile insurance coverage other than comprehensive, successful completion by the individual driver or drivers insured under the policy of an accident prevention education course that meets the following criteria:

    (3) Each insurer shall establish a secondary or merit rating plan for automobile insurance, other than comprehensive coverage. A secondary or merit rating plan required under this subsection must provide for premium surcharges for all coverages for automobile insurance, other than comprehensive coverage, based on any of the following, when that information becomes available to the insurer:

    (a) Substantially at-fault accidents.

    (b) Convictions for, determinations of responsibility for civil infractions for, or findings of responsibility in probate court for civil infractions for violations under chapter VI of the Michigan vehicle code, 1949 PA 300, MCL 257.601 to 257.750. However, an insured must not be merit rated for a civil infraction under chapter VI of the Michigan vehicle code, 1949 PA 300, MCL 257.601 to 257.750, for a period of time longer than that which the secretary of state's office carries points for that infraction on the insured's motor vehicle record.

    (6) This section does not limit insurers or rating organizations from establishing and maintaining statistical reporting territories. This section does not prohibit an insurer from establishing or maintaining, for automobile insurance, a premium discount plan for senior citizens in this state who are 65 years of age or older, if the plan is uniformly applied by the insurer throughout this state. If an insurer has not established and maintained a premium discount plan for senior citizens, the insurer shall offer reduced premium rates to senior citizens in this state who are 65 years of age or older and who drive less than 3,000 miles per year, regardless of statistical data.

    (7) Classifications established under this section for home insurance other than inland marine insurance provided by policy floaters or endorsements must be based only on 1 or more of the following factors:

    (a) Amount and types of coverage.

    (f) Loss experience of the insured, based on prior claims attributable to factors under the control of the insured that have been paid by an insurer. An insured's failure, after written notice from the insurer, to correct a physical condition that presents a risk of repeated loss is a factor under the control of the insured for purposes of this subdivision.

    (g) Use of smoking materials within the structure.

    (h) Distance of the structure from a fire hydrant.

    (i) Availability of law enforcement or crime prevention services.

    (8) Notwithstanding other provisions of this chapter, home insurance risks may be grouped by territory.

    (9) An insurer may use factors in addition to those permitted by this section for insurance if the plan is consistent with the purposes of this act and reflects reasonably anticipated reductions or increases in losses or expenses.
