California Code, Insurance Code - INS § 11628.7

No admitted insurer, licensed to issue motor vehicle liability policies as defined in Section 16450 of the Vehicle Code, shall fail or refuse to accept an application for that insurance, or to issue that insurance, on the basis that the owner of the motor vehicle to be insured is blind. However, notwithstanding any other provision of law, an admitted insurer may exclude from coverage under the policy the unlicensed owner of a motor vehicle who is blind for injuries and damages incurred while the insured vehicle is operated by an unlicensed owner who is blind.

Nothing in this section shall prohibit an insurer from applying its usual and customary underwriting and rating criteria with respect to the operators of the vehicle to be insured, including, but not limited to, the loss experience the insurer has had with respect to the insured vehicle.

No insurer shall raise the premiums of an insured blind person or shall cancel the policy of an insured blind person solely on the basis that the operators of the insured vehicle are changed frequently.
