Do I have uninsured motorist coverage in South Carolina?

If you have a South Carolina auto policy, yes. State law requires UM coverage in every policy issued here, at minimum limits of $25,000 per person and $50,000 per accident. Many drivers carry more without realizing it, and household stacking can multiply what is available. The declaration pages for every policy in your household are the first thing to gather after a serious crash.

What is the difference between UM and UIM coverage?

UM pays when the at-fault driver has no insurance or is never identified. UIM pays when they have insurance but not enough for your losses. UM is mandatory in South Carolina; UIM is optional but must be offered up to your liability limits. They do not combine on a single claim: the at-fault driver's status decides which one applies.

How does stacking work in South Carolina?

Class I insureds, meaning the named insured, spouse, and resident relatives, can combine UM or UIM limits across multiple vehicles and household policies. Each stacked policy's contribution is capped by the coverage on the vehicle involved in the crash, the 'measuring vehicle.' Guest passengers without household coverage of their own generally cannot stack. Whether stacking applies to your crash is a policy-reading exercise, and it is free to have us do it.

The driver who hit me fled the scene. Do I have a claim?

Almost certainly, through your own UM coverage: South Carolina treats unidentified-driver crashes as uninsured motorist claims. Report the crash to law enforcement promptly and preserve everything from the scene. A real investigation also identifies more hit-and-run drivers than people expect, and finding the driver can open a bigger recovery than the UM claim alone.

My own insurance company is fighting my UM claim. Can they do that?

They can defend it, and they will: in a UM/UIM claim your insurer legally stands in the at-fault driver's shoes. What they cannot do is act in bad faith, unreasonably denying, delaying, or underpaying a covered claim. South Carolina recognizes strong bad-faith remedies against carriers that cross that line, which is one more reason these claims belong in experienced hands.

When the At-Fault Driver Can't Pay, Your Own Policy Steps In

Roughly one South Carolina driver in ten carries no insurance at all, and many more carry the bare $25,000 minimum.

South Carolina answered that problem with a rule most states never adopted: uninsured motorist coverage is built into every auto policy issued in this state.

If you have a South Carolina auto policy, you have UM coverage. The question is how much, and whether it stacks.

Underinsured motorist coverage, the optional layer that pays above a too-small policy, is where serious cases are made whole.

A UM claim turns your own insurer into your opponent. It stands in the uninsured driver's shoes and defends the claim like his carrier would have.

UM & UIM in South Carolina: The Essentials

UM coverage is mandatory on every SC policy, minimum 25/50/25
UIM is optional, but every insurer must offer it
Hit-and-run crashes are handled as uninsured motorist claims
Class I insureds can stack coverage across multiple vehicles and policies
Your insurer defends a UM/UIM claim the way an opposing carrier would

UM vs. UIM: Two Coverages, Two Different Jobs

Uninsured motorist coverage: the mandatory floor

UM coverage pays your medical bills, lost wages, and pain and suffering when the at-fault driver carries no insurance, when a hit-and-run driver is never identified, or when the at-fault carrier denies coverage. South Carolina requires it in every policy at 25/50/25 limits under S.C. Code § 38-77-150, and higher UM limits can be purchased.^[1]

Underinsured motorist coverage: the optional layer that decides serious cases

UIM pays the gap when the at-fault driver has insurance, just not enough. A $250,000 injury against a $25,000 policy leaves $225,000 on the table unless UIM covers it. South Carolina insurers must offer UIM up to your liability limits under § 38-77-160, and an offer that was never meaningfully made is a fight worth having: courts here take the "meaningful offer" requirement seriously, and a defective offer can mean coverage gets read into the policy after the fact.

The one distinction that confuses everyone

UM and UIM are not interchangeable, and they do not combine on the same claim. An uninsured driver triggers UM. An underinsured driver triggers UIM. Which side of the line your crash falls on shapes everything about how the claim gets built.

Stacking: How One Crash Can Reach Several Policies

"The declaration page you forgot about may be worth more than the at-fault driver's entire policy."

Stacking is South Carolina's multiplier. Under the case law, a "Class I" insured, the named insured, their spouse, and relatives living in the household, can combine UM or UIM coverage across multiple vehicles and multiple policies.

The practical rules:

Same policy, several cars: two vehicles each carrying $25,000 in UM can stack to $50,000 on one claim.
Several household policies: a Class I insured hurt in their own vehicle can reach the UM/UIM on other at-home policies too.
The measuring-vehicle cap: stacked recovery from each additional policy is limited by the coverage on the vehicle involved in the crash. A $25,000 involved-vehicle limit caps what each stacked policy contributes at $25,000.
No mixing: UM stacks with UM, UIM with UIM. One claim does not stack both.
Class II insureds cannot stack: a guest passenger with no household coverage of their own takes the involved vehicle's limits and stops there.

Stacking is exactly the kind of recovery that never happens by accident. Adjusters do not volunteer it, and the analysis runs on details most people never connect: who lived where, which relative owned what, and how each policy defines an insured. In serious-injury households we routinely find stackable coverage the family did not know existed.

Hit-and-Run Crashes Are UM Claims in South Carolina

When the driver who hit you is never found, South Carolina law routes the claim through your own UM coverage, with requirements worth knowing early: prompt reporting to law enforcement matters, and the crash must be investigated and documented like any liability case, because your insurer will test the story exactly the way a defense lawyer would.

The investigation still matters even when the driver seems gone. Doorbell and business cameras, witness canvassing, and paint transfer evidence identify more fleeing drivers than victims expect, and an identified driver may carry a policy worth more than the UM claim.

Why Your Own Insurer Fights a UM/UIM Claim

Loyalty ends where the claim begins. In a UM or UIM case, your carrier is contractually entitled to defend the claim as the at-fault driver's insurer would have: disputing fault, questioning treatment, and arguing your injuries down. The premium relationship buys nothing at the negotiating table.

Treat a first-party claim like the adversarial process it is. Report promptly, but give no recorded statement without counsel, because everything said to your own adjuster is discoverable in the fight that follows. Document the claim like a lawsuit. And remember that South Carolina law protects policyholders whose insurers cross from hard bargaining into bad faith: an unreasonable denial or lowball has consequences under the state's insurance bad faith doctrine.

Fault rules still apply to the underlying claim, including the 50 percent bar covered in our page on South Carolina comparative negligence, and the whole framework sits on the state's at-fault system, explained in whether South Carolina is a no-fault state.
