South Carolina Car Insurance: Required UM and Optional UIM

Understand South Carolina’s required liability and UM, optional UIM offers and safety-glass coverage questions.

Required UM is not the UIM election

DOI lists liability 25/50/25 and requires UM at those minima. It says UIM must be offered but need not be purchased. Obtain the completed UIM offer and selection rather than inferring it from the UM line.

Glass questions belong to vehicle protection

The regulator says auto insurers cannot impose a deductible for safety-glass repair or replacement. Ask which protection applies to the actual glass loss; the statement should not be read as creating coverage for a car without the relevant protection.

A South Carolina comparison

Prepare a consumer-assistance question

DOI’s Office of Consumer Services handles questions and provides complaint entry points. Keep policy, election, claim evidence and insurer response together. This draft avoids repeating a generic low-value-car recommendation or predicting a total-loss settlement from a single threshold.

Compare UM and UIM without treating them as synonyms

The state summary describes required UM and an offer of UIM that need not be purchased. Keep the actual UIM offer and election. A UM line on the declarations does not document the UIM decision.

Fictional price comparison: Both proposals run for six months with the same liability, UM and vehicle deductibles. One is $840 with selected UIM; another is $780 without it. The $60 difference is not a saving for equivalent protection. Ask for matched selections first. These are invented amounts, not South Carolina premiums or a recommendation to accept or reject UIM.

Glass needs both a coverage question and a deductible question

The regulator’s safety-glass statement does not create every missing vehicle coverage. Identify the actual loss and applicable protection first, then ask about the statutory deductible treatment. Do not assume the ordinary comprehensive deductible is the correct amount for an eligible safety-glass claim, or that every damaged item is safety glass.

Hypothetical: A selected comprehensive policy shows a $500 deductible, while a shop supplies an $850 windshield replacement estimate. Do not automatically subtract $500. Ask whether the glass loss qualifies for the applicable no-deductible treatment and which amount is accepted. The example deliberately leaves the claim payment undetermined because scope must be established.

Keep a useful South Carolina claim file

Save the offer forms, declarations, relevant endorsement, photographs, estimate and insurer’s written explanation. Identify whether your disagreement concerns eligibility, amount, deductible or a missing election. For UIM questions, keep the current form and selected limits; for glass, keep the damage and repair record.

The Office of Consumer Services is an assistance route, not a guarantee of a chosen settlement. Current glass statutory scope and UIM forms remain private review questions. That distinction allows a practical guide without silently converting a summary into an individualized coverage promise.
