Uninsured and Underinsured Motorist Coverage in Georgia and South Carolina: What You Need to Know

Being hit by a driver who carries no insurance — or whose policy limits fall far short of covering your injuries — is one of the most frustrating situations an accident victim can face. Fortunately, uninsured/underinsured motorist (UM/UIM) coverage exists specifically to protect you in these scenarios. According to the Insurance Information Institute, reporting Insurance Research Council estimates for 2023, 15.4 percent of U.S. motorists (more than one in seven) were uninsured; Georgia’s rate was 19.0 percent and South Carolina’s 10.3 percent. If you were injured by an uninsured or underinsured driver in Georgia or South Carolina, understanding how UM/UIM coverage works — and how to maximize your recovery — can make the difference between full compensation and a financial shortfall.

What Is Uninsured/Underinsured Motorist Coverage?

Uninsured motorist (UM) coverage pays for your injuries and damages when the at-fault driver carries no liability insurance whatsoever. Underinsured motorist (UIM) coverage fills the gap when the at-fault driver’s policy limits are not enough to cover your total losses. These coverages are part of your own auto insurance policy — they protect you, your passengers, and often your household family members regardless of which vehicle you are in at the time of the crash.

UM/UIM coverage typically pays for the same types of damages that a liability claim would cover, including medical expenses, lost wages, pain and suffering, and other compensatory damages. The critical difference is that you are filing against your own insurance company rather than the at-fault driver’s carrier. This dynamic changes how the claim is negotiated and resolved, particularly when disputes arise about the value of your injuries. Related cases like car accidents and motorcycle accidents frequently involve UM/UIM claims when the other driver is uninsured.

UM vs. UIM: Understanding the Difference

While these coverages are often bundled together, they serve different purposes:

Understanding which type of coverage applies is the first step in evaluating your claim. In hit-and-run cases, UM coverage is often the only avenue for recovery since the at-fault driver cannot be identified. Both Georgia and South Carolina have specific rules about when and how these coverages interact.

Georgia UM/UIM Laws and Requirements

Georgia law provides strong protections for drivers through its UM/UIM statutes. Under O.C.G.A. § 33-7-11, every automobile liability insurance policy issued in Georgia must include UM/UIM coverage unless the named insured affirmatively rejects the coverage in writing. This means UM/UIM is the default — you have it unless you specifically opted out. For a fuller walk-through, see our Georgia uninsured motorist coverage guide.

Key Georgia UM/UIM Rules

• Coverage limits: UM/UIM coverage equals your liability limits unless you affirmatively choose a lower limit. A rejection must be in writing.
• Add-on vs. reduced coverage: Georgia UIM is “added-on” by default, meaning your UIM benefits are added on top of the at-fault driver’s liability coverage, unless you selected cheaper reduced-by coverage in writing (O.C.G.A. § 33-7-11(b)(1)(D)(ii)). If the at-fault driver has $25,000 in coverage and you have $100,000 in UIM, your total available recovery is $125,000, up to your actual losses; reduced-by coverage would pay $75,000 of UIM.
• Stacking across policies: You can stack UM coverage from every policy under which you are an insured, and clauses that try to prevent stacking across policies are unenforceable. Several vehicles on a single policy generally do not stack (Crafter v. State Farm, 2001).
• Statute of limitations: UM/UIM claims in Georgia are subject to the same 2-year statute of limitations for personal injury under O.C.G.A. § 9-3-33.
• Limited release: Settle with the at-fault driver’s carrier only through a limited release under O.C.G.A. § 33-24-41.1; a general release can extinguish your UIM claim. Your UM carrier cannot require its consent, but it must be served with any lawsuit (§ 33-7-11(d)).

Georgia’s comparative fault rules also apply: under O.C.G.A. § 51-12-33, you can recover UM/UIM benefits as long as you are less than 50% at fault for the accident. Your recovery is reduced by your percentage of fault. This same framework applies to truck accident claims and pedestrian accident claims involving uninsured drivers.

South Carolina UM/UIM Laws and Requirements

South Carolina’s UM/UIM framework, governed by S.C. Code § 38-77-150 and related sections, also strongly favors coverage, though the rules differ from Georgia in several important ways.

Key South Carolina UM/UIM Rules

• Mandatory coverage: Under S.C. Code § 38-77-150, UM coverage is required on every auto liability policy and cannot be rejected. Minimum UM limits match the state’s minimum liability limits ($25,000 per person / $50,000 per accident), plus $25,000 for property damage. UIM and UM above the minimums are optional (§ 38-77-160).
• Excess coverage: Like Georgia’s default, South Carolina UIM pays on top of the at-fault driver’s limits, up to your UIM limit and your actual damages (Broome v. Watts, 1995). If the at-fault driver has $25,000 and your UIM limit is $100,000, you can recover up to $125,000. There is no reduced-by option.
• Stacking for Class I insureds: A named insured or resident relative whose vehicle was involved may stack coverage from other vehicles and policies, capped at the coverage on the vehicle involved (S.C. Code § 38-77-160); an exclusion blocking that is invalid (Carter v. Standard Fire, 2013). Other insureds cannot stack.
• Statute of limitations: UM/UIM claims fall under South Carolina’s 3-year statute of limitations for personal injury (S.C. Code § 15-3-530).
• Meaningful offer requirement: Insurers must make a meaningful offer of optional UIM on the form required by S.C. Code § 38-77-350; without one, you may have UIM up to your liability limits by operation of law (State Farm v. Wannamaker, 1987). Policy terms that conflict with the UM/UIM statutes are unenforceable.

South Carolina’s modified comparative fault rule allows recovery as long as you are less than 51% at fault. This slightly more favorable threshold compared to Georgia’s 50% rule can make a significant difference in close-call liability situations, particularly in bicycle accident cases and premises liability claims where fault allocation is contested.

When UM/UIM Coverage Applies After a Crash

UM/UIM coverage comes into play in several common situations that accident victims in the Southeast encounter frequently:

Hit-and-Run Accidents

When a driver causes an accident and flees the scene, your UM coverage steps in because the at-fault driver cannot be identified or located. Both states require physical contact or corroboration: in Georgia, an eyewitness other than you (O.C.G.A. § 33-7-11(b)(2)); in South Carolina, a witness affidavit or a recording of the crash, plus a timely police report (S.C. Code § 38-77-170, amended in 2024). Hit-and-run scenarios often arise in motorcycle crashes and pedestrian accidents where the driver may not even realize they caused a collision.

Uninsured Drivers

Despite legal requirements, an estimated 19.0 percent of Georgia drivers and 10.3 percent of South Carolina drivers were uninsured in 2023. When one of these drivers causes an accident, your UM coverage provides the only viable path to compensation for medical bills, lost income, and pain and suffering.

Underinsured Drivers

A driver who carries only minimum coverage ($25,000 per person in both states) may be technically insured but practically underinsured when your injuries are severe. Traumatic brain injuries, spinal cord injuries, and other catastrophic injuries routinely generate medical bills that far exceed minimum policy limits, making UIM coverage essential.

Stolen or Borrowed Vehicles

If the at-fault vehicle was stolen, the vehicle owner’s insurance typically will not cover the accident. Your UM coverage fills this gap. Similarly, complications arise when a borrowed vehicle is involved and coverage disputes emerge between multiple insurers.

Stacking UM/UIM Coverage for Higher Limits

“Stacking” refers to the ability to combine UM/UIM coverage limits across multiple vehicles or policies, effectively multiplying your available coverage. For families with multiple insured vehicles, stacking can significantly increase the amount of UM/UIM benefits available after a serious crash.

How Stacking Works

In South Carolina, if you are a Class I insured with $100,000 in UIM coverage on each of three vehicles and one was in the crash, stacking could give you $300,000, even on a single policy. In Georgia, three vehicles on one policy generally do not stack, but three separate policies do. Neither state has a statutory anti-stacking waiver.

Challenging Anti-Stacking Provisions

Insurance companies frequently include anti-stacking provisions in their policies. In Georgia, clauses that try to prevent stacking across separate policies are unenforceable (State Farm v. Hancock, 1982). In South Carolina, exclusions that conflict with § 38-77-160 are void, and an insurer that never made a meaningful UIM offer may owe UIM by operation of law. An experienced attorney can review your policy to determine whether an anti-stacking provision is enforceable or can be challenged to unlock additional coverage for your claim.

How to File a UM/UIM Claim in Georgia and South Carolina

Filing a UM/UIM claim follows a structured process, but it differs from a standard third-party liability claim because you are dealing with your own insurance company:

Step 1: Document the Accident

Obtain the police report, gather witness information, photograph the scene and vehicle damage, and keep all medical records. If the at-fault driver is uninsured, the police report should note the lack of insurance. For hit-and-run cases, report the accident to law enforcement immediately.

Step 2: Notify Your Insurance Company

Report the accident to your own auto insurer promptly. Most policies require timely notification, and unreasonable delay can jeopardize your claim. Provide the police report, the at-fault driver’s information (if known), and documentation of your injuries.

Step 3: Exhaust the At-Fault Driver’s Coverage (UIM Claims)

For underinsured motorist claims, you must typically exhaust the at-fault driver’s liability limits before your UIM coverage activates. Neither state lets your UIM carrier require its consent before you accept those limits (O.C.G.A. § 33-24-41.1(c); S.C. Code § 38-77-160). In Georgia, settle through a limited release so the UIM claim survives; in South Carolina, the UIM carrier may take over the defense once the at-fault carrier pays its limits. In both states, keep your UIM carrier informed and make sure it is served with any lawsuit.

Step 4: Submit Your UIM/UM Demand

Compile your medical records, bills, lost wage documentation, and a demand letter to your own insurer. Treat this demand with the same thoroughness you would apply to a third-party liability demand. The demand should include evidence of the at-fault driver’s liability, your damages, and documentation supporting your claim value.

Step 5: Negotiate or File Suit

Many UM/UIM disputes are resolved through negotiation. If negotiations fail, the claim is decided in a lawsuit against the at-fault driver (or “John Doe” in a hit-and-run). Your UM/UIM carrier is served with the suit and may defend in the driver’s name. Georgia forbids arbitration clauses in UM endorsements (O.C.G.A. § 33-7-11(g)).

Common UM/UIM Disputes Insurance Companies Raise

Even though you are filing against your own insurer, UM/UIM claims are frequently contested. Your insurance company has a financial incentive to minimize what it pays, and common disputes include:

• Coverage denial: The insurer may claim you validly rejected UM/UIM coverage or that the policy was not in effect at the time of the accident.
• Anti-stacking enforcement: Insurers routinely argue that anti-stacking provisions limit your available coverage, even when those provisions are unenforceable.
• Release disputes: In Georgia, insurers may argue a general release of the at-fault driver extinguished your UM/UIM claim; a limited release under O.C.G.A. § 33-24-41.1 preserves it.
• Causation challenges: The insurer may dispute whether your injuries were caused by the accident or pre-existed the crash — an argument common in wrongful death claims and cases involving burn injuries.
• Policy limit disputes: Disagreements about applicable limits, particularly when multiple policies or vehicles are involved.
• Comparative fault reduction: Your insurer may argue that your own negligence contributed to the accident, reducing your recovery under Georgia’s or South Carolina’s comparative fault rules.

How a Personal Injury Attorney Helps with UM/UIM Claims

UM/UIM claims require navigating complex policy language, state-specific insurance regulations, and an insurance company that — despite being “your” insurer — is motivated to pay as little as possible. An experienced car accident attorney provides critical advantages in these claims:

• Policy review: Analyzing your policy to identify all available UM/UIM coverage, including potential stacking opportunities and unenforceable anti-stacking provisions
• Release protection: Ensuring that your UIM rights are preserved when settling with the at-fault driver’s carrier
• Claims valuation: Building a comprehensive demand that accounts for all current and future damages — medical costs, lost earnings, diminished quality of life, and pain and suffering
• Bad faith claims: When your insurer unreasonably denies or delays a valid UM/UIM claim, an attorney can pursue a bad faith action for additional damages
• Trial advocacy: Preparing your case for a jury, because your UM/UIM carrier can defend the lawsuit in the at-fault driver’s name
