230 R.I. Code R. 230-RICR-20-05-1.6
If an insured elects Uninsured/Underinsured Motorist liability limits that are less than the liability limits or rejects Uninsured Motorist Property Damage Liability coverage, these selections shall be followed and included in any renewal, supplementary, replacement or substitute policy, even if liability limits or insured vehicles are subsequently changed. Where the insured elects Uninsured/Underinsured Motorist liability limits equal to the bodily injury liability limits and the bodily injury liability limits are later changed, the Uninsured/Underinsured Motorist bodily injury Liability limits will also change to reflect the same amount. The insured may change any original or subsequent election by notifying the company in writing of his/her desire for such change.
