Uninsured Motorist Coverage in South Carolina, Explained
You already own the coverage this article is about. Here's what it actually does, what the optional version does, and the part nobody warns you about: when you use it, your own insurer switches sides.
The Coverage You Bought for a Driver You've Never Met
Every auto insurance policy lawfully issued in South Carolina contains uninsured motorist coverage. Not "should contain." Contains — S.C. Code § 38-77-150 forbids issuing a policy without it. Which means you have spent years paying premiums for insurance that covers a stranger's failure to buy insurance, and if you're like most of my clients, nobody has ever explained what it does until the day you desperately need it to work.
That day is usually one of two phone calls. Either the police tell you the driver who hit you has no insurance, or an adjuster tells you the driver's coverage is nowhere near your hospital bill. This is not rare. The Insurance Research Council's most recent study found that in 2023, more than one in seven drivers nationwide — 15.4 percent — were driving uninsured, and more than one in six carried too little coverage for the harm they cause. South Carolina, with its 25/50/25 minimum limits under § 38-77-140, is exactly the kind of state where "insured" and "adequately insured" part company fast: one surgery can run past $25,000 before you've left the hospital.
So this post is the owner's manual nobody gave you. What UM is, what UIM is, how the two get stacked, and — the section I most want you to read — what it feels like to make a claim against your own insurance company, because it does not feel the way the commercials promised.
UM vs. UIM: One Is Mandatory, One Is a Choice You May Not Remember Making
UM — uninsured motorist coverage (you have this)
What it does: if the at-fault driver has no insurance at all, your own policy steps into their shoes and pays what they legally owe you — up to your UM limits. Under § 38-77-150 it rides on every SC policy at no less than the state minimums: $25,000 per person and $50,000 per accident for bodily injury, $25,000 for property damage (§ 38-77-140). Two details almost nobody knows. First, UM includes property damage — the statute requires no less than $25,000 of it, so the uninsured driver who totals your car is a UM claim too, though the policy may carve out the first $200 of the loss. Second, UM is fault-based: it pays sums you are "legally entitled to recover" from the uninsured driver. You still have to prove the crash was their fault, the same as in any injury case — which is why South Carolina's modified comparative negligence rule, the 51% bar, applies with full force to UM claims.
UIM — underinsured motorist coverage (check tonight)
What it does: if the at-fault driver has insurance but not enough, UIM pays the layer of damages above their limits, up to your UIM limits. Under § 38-77-160, every SC insurer must offer you UIM up to your liability limits — but it's optional. It's on your policy only if you, or whoever set up the policy years ago, said yes. In my experience the person who declined it saved a few dollars a month and was never told what they were declining: the only coverage in the whole policy that protects your family against everyone else's bad decisions at once.
The same section lets you buy additional UM above the minimums too, up to your liability limits. If you carry $100,000 in liability coverage because you're a careful person, but only $25,000 in UM/UIM, you've insured everyone on the road better than you've insured your own passengers. I'd rather you fix that this week, as a reader, than need me to explain it to you later as a client.

The Role Reversal: Your Own Insurer Becomes the Other Side
Here is the sentence I say at more kitchen tables than any other: the moment you make a UM or UIM claim, the company you've been paying all these years becomes the adversary. Not because your agent is dishonest, and not because anyone at the company dislikes you. Because of the arithmetic of the claim itself: every dollar your injuries are worth is now a dollar your own carrier pays. The friendly incentives that existed when you were merely a customer are gone. You are now a cost.
South Carolina law doesn't hide this — it builds a courtroom around it. Under § 38-77-150, before you can pursue a UM claim in court, your own insurer must be served with the pleadings, and it then has the statutory right to appear and defend in the name of the uninsured motorist. Read that again. In a South Carolina courtroom, the lawyer arguing that the crash was your fault, that your neck injury is exaggerated, that your damages are modest — that lawyer can be hired by your insurance company, standing up under the uninsured driver's name. The company whose jingle you know by heart is, functionally and legally, the defense.
Once you understand the role reversal, several things I tell clients stop sounding paranoid and start sounding obvious:
- The recorded statement your own adjuster wants is not a formality. It is potential defense evidence, gathered while you're still medicated and being agreeable. Everything in my guide on what to say when the adjuster calls applies doubly when the adjuster works for your carrier.
- Comparative fault is their best weapon. If they can pin 51% of the crash on you, they pay nothing at all under Nelson v. Concrete Supply Co. — and every percentage point below that shaves the check.
- Your damages get contested like any defendant would contest them. The factors that build a case's value — I walk through all of them in what is my case worth — have to be proven to your own carrier with the same rigor as to a stranger's.
None of this means UM/UIM coverage is a trick. It's the opposite — it is often the only real money in the case. It means the claim has to be built, documented, and, when necessary, litigated. "They're my insurance company, they'll take care of me" is the most expensive sentence in South Carolina injury law.
Stacking: When Two Policies Pay on One Crash
"Stacking" means combining UM or UIM coverage from more than one policy — or more than one vehicle — on a single crash. South Carolina permits it in defined circumstances, and it is one of the most litigated corners of the state's insurance law, so treat this as a map, not a survey.
The statute sets the outer walls. Under § 38-77-160, if you carry UM or UIM above the basic limits, you're protected "only to the extent of the coverage [you have] on the vehicle involved in the accident" — and if none of your own vehicles was in the crash (say you were hurt as a passenger in a friend's car, or as a pedestrian), coverage is available only to the extent of the coverage on any one of your vehicles carrying the excess or underinsured protection. On top of the statute, South Carolina case law sorts claimants into two classes: Class I insureds — the named insured, spouse, and resident relatives — may generally stack; Class II insureds — guests and other permissive users of the vehicle — generally may not.
Why should a hurt person care about this doctrine? Because stacking is frequently the difference between a claim capped at one $25,000 layer and a claim with two or three layers of coverage — and because nobody at the insurance company is obligated to volunteer that your household's second policy, or your teenager's policy, or the policy on the truck parked at home, might apply. Finding every policy that touches a crash is one of the first things I do in any serious case, and it's detail work: household composition, who lives where, whose name is on what declarations page. When a client's mother's policy adds a layer of UIM to the case, that layer wasn't found by an adjuster. It was found by a lawyer looking for it.

The Kitchen-Table Declarations-Page Audit
When I make a house call, I ask for one document before anything else: the declarations page — the one- or two-page summary at the front of the policy. (If yours reads like a foreign language, I've decoded the whole page line by line in how to read your auto insurance policy in South Carolina.) Here is the exact pass I make over it, which you can do yourself tonight in ten minutes:
- Find the UM line. It's there — the law requires it. Note the bodily-injury limits (per person / per accident) and the property-damage limit.
- Find the UIM line — or its absence. If there is no UIM line, that's the single most important blank space on the page. The at-fault driver carrying state-minimum coverage is a scenario UIM exists for, and it isn't there.
- Compare your liability limits to your UM/UIM limits. If you protect strangers better than your own passengers, you've found the imbalance most SC households have and almost none know about.
- List every policy in the household. Spouse's policy, a resident relative's policy, the extra vehicle. After a crash, each one is a potential layer — this is the raw material of the stacking analysis above.
- Check who's a named insured and who's just a driver. That distinction can decide which class of insured you are, which can decide whether stacking is on the table at all.
If you've already been hit, bring every declarations page in the house to the consultation — or I'll come read them at your table. The coverage picture on day one is almost never the real coverage picture, and finding money is free to you either way: the consultation costs nothing, and the fee if you hire me is contingency — a percentage agreed in writing up front, and no fee unless we win. Where the money then goes — hospital liens, health insurance, your net — is its own subject, and I've written about it in who pays the medical bills.
One scenario deserves its own guide: the driver who hit you didn't just lack insurance — they drove off entirely. South Carolina lets you bring a UM claim against a driver who was never identified, through a "John Doe" action with its own strict conditions. I've written the full walkthrough, including the recording provision most articles miss, in my hit-and-run guide. And when the crash involves an Uber or Lyft, the coverage question changes shape entirely — the app's status decides which of three statutory insurance tiers applies, and I've mapped them in my Uber and Lyft accident guide.
UM & UIM FAQs
Is uninsured motorist coverage required in South Carolina?
Yes. Under S.C. Code § 38-77-150, no auto insurance policy may be issued or delivered in South Carolina without an uninsured motorist provision, at limits no lower than the 25/50/25 minimums in § 38-77-140. If you have a lawful SC auto policy, you have UM coverage — whether or not anyone ever explained it to you.
Do I have underinsured motorist (UIM) coverage?
Only if you (or whoever bought the policy) accepted it. Under § 38-77-160, insurers must offer UIM up to your liability limits, but it is optional — it is on your policy only if it was selected. The one way to know is to read your declarations page, and I will read it with you for free. Bring it to the consultation, or I'll come to your kitchen table and we'll go through it together.
Does UM coverage pay for damage to my car, or just my injuries?
Both. South Carolina's UM statute requires no less than $25,000 in property damage coverage in any one accident, though the policy may exclude the first $200 of the loss. So if an uninsured driver totals your car, your own UM coverage is generally where the repair or replacement money comes from.
What if the driver who hit me took off and was never found?
Your UM coverage can still pay through what's called a John Doe claim — a lawsuit against the unknown driver by that fictional name, with your own insurer defending. South Carolina puts specific conditions on these claims, including a prompt police report. I cover the whole process, including the recording provision most articles miss, in my hit-and-run guide.
How long do I have to bring a UM or UIM claim in South Carolina?
The underlying injury claim is generally governed by South Carolina's three-year statute of limitations for personal injury, S.C. Code § 15-3-530 — but UM/UIM claims layer contract and procedural requirements on top of that, and waiting is how coverage gets lost. Evidence of the other driver's uninsured status, and the witnesses who can prove fault, are easiest to find early. Call me before you talk to any adjuster, including your own.
Hit by a driver with no insurance — or not enough?
Free consultation. No fee unless we win. Bring your declarations page — or Tom will come to your kitchen table and read it with you.
