"The California Insurance Code requires an insurer to provide uninsured motorists coverage in each bodily injury liability insurance policy it issues covering liability arising out of the ownership, maintenance, or use of a motor vehicle. Those provisions also permit the insurer and the applicant to delete the coverage completely or to delete the coverage when a motor vehicle is operated by a natural person or persons designated by name. Uninsured motorists coverage insures the insured, his or her heirs, or legal representatives for all sums within the limits established by law, that the person or persons are legally entitled to recover as damages for bodily injury, including any resulting sickness, disease, or death, to the insured from the owner or operator of an uninsured motor vehicle not owned or operated by the insured or a resident of the same household. An uninsured motor vehicle includes an underinsured motor vehicle as defined in subdivision (p) of Section 11580.2 of the Insurance Code."
The agreement may contain additional statements not in derogation of or in conflict with the foregoing. The execution of the agreement shall relieve the insurer of liability under this section while the agreement remains in effect.
"The California Insurance Code requires an insurer to provide uninsured motorists coverage in each bodily injury liability insurance policy it issues covering liability arising out of the ownership, maintenance, or use of a motor vehicle. Those provisions also permit the insurer and the applicant to agree to provide the coverage in an amount less than that required by subdivision (m) of Section 11580.2 of the Insurance Code but not less than the financial responsibility requirements. Uninsured motorists coverage insures the insured, his or her heirs, or legal representatives for all sums within the limits established by law, that the person or persons are legally entitled to recover as damages for bodily injury, including any resulting sickness, disease, or death, to the insured from the owner or operator of an uninsured motor vehicle not owned or operated by the insured or a resident of the same household. An uninsured motor vehicle includes an underinsured motor vehicle as defined in subdivision (p) of Section 11580.2 of the Insurance Code."
The agreement may contain additional statements not in derogation of or in conflict with this paragraph. However, it shall be presumed that an application for a policy of bodily injury liability insurance containing uninsured motorist coverage in an amount less than that required by subdivision (m), signed by the named insured and approved by the insurer, with a policy effective date after January 1, 1985, shall be a valid agreement as to the amount of uninsured motorist coverage to be provided.
As used in this section, "uninsured motor vehicle" also means an insured motor vehicle where the liability insurer thereof is unable to make payment with respect to the legal liability of its insured within the limits specified therein because of insolvency. An insurer's solvency protection shall be applicable only to accidents occurring during a policy period in which its insured's motor vehicle coverage is in effect where the liability insurer of the tortfeasor becomes insolvent within one year of the accident. In the event of payment to any person under the coverage required by this section and subject to the terms and conditions of the coverage, the insurer making the payment, shall to the extent thereof, be entitled to any proceeds that may be recoverable from the assets of the insolvent insurer through any settlement or judgment of the person against the insolvent insurer.
Nothing in this section is intended to exclude from the definition of an uninsured motor vehicle any motorcycle or private passenger-type four-wheel drive motor vehicle if that vehicle was subject to and failed to comply with the Financial Responsibility Law of this state.
