The Short Answer
South Carolina makes uninsured motorist coverage mandatory on every auto policy, but only at the state minimum limits of 25/50/25 (S.C. Code §§ 38-77-140, 38-77-150). Higher UM limits, and all underinsured motorist coverage, are optional coverages the insurer must offer (S.C. Code § 38-77-160). You do not have to opt in to the basic UM, you already have it.
Uninsured and Underinsured Coverage in South Carolina
South Carolina makes uninsured motorist coverage mandatory on every auto policy, but only at the state minimum limits of 25/50/25 (S.C. Code §§ 38-77-140, 38-77-150). Higher UM limits, and all underinsured motorist coverage, are optional coverages the insurer must offer (S.C. Code § 38-77-160). You do not have to opt in to the basic UM, you already have it.
This is a real structural advantage over Alabama and Georgia. The practical questions in a South Carolina case become how much UM/UIM is available, whether UIM was purchased, and how coverage across vehicles and policies coordinates, which is exactly where careful claims handling protects recovery.
The South Carolina Filing Deadline
Most South Carolina personal injury lawsuits must be filed within three years of the date of injury under S.C. Code § 15-3-530, a year longer than Alabama and Georgia. Do not let the longer period create false comfort: evidence, witnesses, and camera footage disappear on the same schedule everywhere.
Claims against South Carolina governments run through the South Carolina Tort Claims Act: generally two years to sue, extended to three years if a verified claim was filed within one year (S.C. Code §§ 15-78-80, 15-78-110), with caps on recoverable damages. The Act's procedures are technical enough that government-defendant claims should be in a lawyer's hands early.
Fault in South Carolina: Modified comparative negligence (51% bar)
South Carolina applies modified comparative negligence: as long as your share of fault does not exceed 50%, you may recover, with damages reduced by your percentage of fault; if you are more at fault than the defendant, recovery is barred. The rule comes from the South Carolina Supreme Court's adoption of comparative fault in Nelson v. Concrete Supply Co. For causes of action accruing on or after January 1, 2026, the amended apportionment statute (S.C. Code § 15-38-15, under Act No. 42 of 2025) spreads fault across the plaintiff, the defendants, and nonparties, and a defendant found less than 50% at fault answers only for its own share rather than jointly for the whole; the greater-than-50% bar on the plaintiff is unchanged. Either way, disciplined fault development is the core of every contested claim.
A Worked Example Under South Carolina Law
A hit-and-run driver causes your injuries and is never found, leaving no at-fault policy to pursue.
In South Carolina, you are covered, because UM coverage is mandatory on every auto policy (S.C. Code § 38-77-150). A phantom or uninsured driver does not leave you empty-handed here, which is a real structural advantage over Alabama and Georgia.
Illustration only, real cases turn on their specific facts.
Steps to Protect Your Claim
1.
Get medical care immediately and follow through
See a doctor even if you feel 'mostly fine.' Adrenaline masks injuries, and gaps in treatment are the first thing insurers use to argue you were not really hurt.
2.
Document everything while it exists
Photograph the scene, vehicles, hazards, and visible injuries. Get names and contact information for witnesses, and request any incident or police report number.
3.
Do not give a recorded statement before getting advice
You are generally not obligated to give the other side's insurer a recorded statement. Under South Carolina's modified comparative negligence (51% bar), what you say can be used to put fault on you.
4.
Mind the South Carolina clock
Three years (S.C. Code § 15-3-530) is the outer limit, and government-defendant claims run far shorter. Building a strong case takes months, so the practical deadline is always sooner.
Costly Mistakes to Avoid
Accepting the first settlement offer before you know the full extent of your injuries.
Posting about the accident or your activities on social media, where insurers will look for ways to dispute your claim.
Giving a recorded statement or signing a blanket medical release without understanding how it will be used.
Letting gaps appear in your medical treatment, which insurers treat as proof you recovered.
Waiting near your state's filing deadline to seek help, when evidence has already started to disappear.

South Carolina Questions, Answered
How long do I have to act in South Carolina?
Most South Carolina personal injury lawsuits must be filed within three years of the date of injury under S.C. Code § 15-3-530, a year longer than Alabama and Georgia. Do not let the longer period create false comfort: evidence, witnesses, and camera footage disappear on the same schedule everywhere.
What if I was partly at fault under South Carolina law?
South Carolina applies modified comparative negligence: as long as your share of fault does not exceed 50%, you may recover, with damages reduced by your percentage of fault; if you are more at fault than the defendant, recovery is barred. The rule comes from the South Carolina Supreme Court's adoption of comparative fault in Nelson v. Concrete Supply Co. For causes of action accruing on or after January 1, 2026, the amended apportionment statute (S.C. Code § 15-38-15, under Act No. 42 of 2025) spreads fault across the plaintiff, the defendants, and nonparties, and a defendant found less than 50% at fault answers only for its own share rather than jointly for the whole; the greater-than-50% bar on the plaintiff is unchanged. Either way, disciplined fault development is the core of every contested claim.
Does UM coverage apply to hit-and-run accidents?
It often can, depending on your policy terms and the circumstances. Uninsured motorist coverage is frequently designed to apply when an unidentified or uninsured driver causes the crash.
Can I have UM/UIM coverage without knowing it?
Yes. Because insurers must offer it and it can usually be waived only in writing, you may already carry it. Check your declarations page or ask your agent to confirm.
Will using my own UM coverage raise my rates?
That depends on your insurer and the facts. Concerns about rates should not stop you from understanding your coverage; an attorney can help you evaluate how best to pursue available coverage after a crash.
