(9) Insurers may offer policies of uninsured motorist coverage containing policy provisions, in language approved by the office, establishing that if the insured accepts this offer:
(a) The coverage provided as to two or more motor vehicles shall not be added together to determine the limit of insurance coverage available to an injured person for any one accident, except as provided in paragraph (c).
(b) If at the time of the accident the injured person is occupying a motor vehicle, the uninsured motorist coverage available to her or him is the coverage available as to that motor vehicle.
(c) If the injured person is occupying a motor vehicle which is not owned by her or him or by a family member residing with her or him, the injured person is entitled to the highest limits of uninsured motorist coverage afforded for any one vehicle as to which she or he is a named insured or insured family member. Such coverage shall be excess over the coverage on the vehicle the injured person is occupying.
(d) The uninsured motorist coverage provided by the policy does not apply to the named insured or family members residing in her or his household who are injured while occupying any vehicle owned by such insureds for which uninsured motorist coverage was not purchased.
(e) If, at the time of the accident the injured person is not occupying a motor vehicle, she or he is entitled to select any one limit of uninsured motorist coverage for any one vehicle afforded by a policy under which she or he is insured as a named insured or as an insured resident of the named insured's household.
In connection with the offer authorized by this subsection, insurers shall inform the named insured, applicant, or lessee, on a form approved by the office, of the limitations imposed under this subsection and that such coverage is an alternative to coverage without such limitations. If this form is signed by a named insured, applicant, or lessee, it shall be conclusively presumed that there was an informed, knowing acceptance of such limitations on behalf of all insureds. When the named insured, applicant, or lessee has initially accepted such limitations, such acceptance shall apply to any policy which renews, extends, changes, supersedes, or replaces an existing policy unless the named insured requests deletion of such limitations and pays the appropriate premium for such coverage. Any insurer who provides coverage which includes the limitations provided in this subsection shall file revised premium rates with the office for such uninsured motorist coverage to take effect prior to initially providing such coverage. The revised rates shall reflect the anticipated reduction in loss costs attributable to such limitations but shall in any event reflect a reduction in the uninsured motorist coverage premium of at least 20 percent for policies with such limitations. Such filing shall not increase the rates for coverage which does not contain the limitations authorized by this subsection, and such rates shall remain in effect until the insurer demonstrates the need for a change in uninsured motorist rates pursuant to s. 627.0651.
