You did everything right. You carried insurance, you drove carefully, and then someone else caused a crash that left you hurt. When the dust settles, you learn the at-fault driver had no insurance at all, or far too little to cover your medical bills. This is the moment an uninsured motorist claim can protect you and your family. In South Carolina, your own auto policy may include coverage that steps in when the other driver cannot pay. Understanding how that coverage works, before you ever need it, can make a real difference for crash victims across Charleston and the Lowcountry.
At our firm, we help injured people in Mount Pleasant, North Charleston, Summerville, and the surrounding communities understand the coverage they already own. Below, we explain uninsured and underinsured motorist coverage in plain English, why South Carolina’s minimum limits often fall short, and how a first-party claim against your own insurer actually works.
What is uninsured and underinsured motorist coverage?
Both types of coverage exist for one simple reason: not every driver carries enough insurance, and some carry none at all. When the person who hurt you cannot fully pay for the harm they caused, this coverage on your own policy can help fill the gap.
Uninsured motorist (UM) coverage
Uninsured motorist coverage protects you when the at-fault driver has no liability insurance, or when the driver flees the scene and is never identified. South Carolina law requires every auto policy to include UM coverage at least at the state’s minimum limits. Under the general framework of South Carolina Code Section 38-77-150, this protection is mandatory, which means you almost certainly already have it.
UM coverage matters most in two situations. The first is when the responsible driver simply broke the law and drove without insurance. The second is a hit-and-run accident, sometimes involving a so-called phantom vehicle that runs you off the road and disappears. In many of those cases, your own UM coverage becomes the primary source of recovery.
Underinsured motorist (UIM) coverage
Underinsured motorist coverage addresses a different problem. Here, the at-fault driver does have insurance, but not enough to cover the full extent of your injuries. An underinsured motorist claim South Carolina drivers can rely on covers the gap between what the at-fault driver’s policy pays and what your damages actually total.
Unlike UM coverage, UIM coverage is optional in South Carolina. However, under the general framework of South Carolina Code Section 38-77-160, insurers are required to offer it to you. Many people accept that offer without fully understanding it, and many decline it without realizing how valuable it can be. If you are not sure whether you carry UIM coverage, your policy declarations page will tell you, and we are glad to help you read it.
Why South Carolina’s minimum limits often are not enough
South Carolina’s minimum liability limits are commonly written as 25/50/25. That means a basic policy must provide at least $25,000 in bodily injury coverage per person, $50,000 in bodily injury coverage per accident, and $25,000 in property damage coverage.
Those numbers can sound substantial until you face a serious injury. A single ambulance ride, an emergency room visit, surgery, and a short hospital stay can easily exceed $25,000 on their own. Add physical therapy, follow-up care, lost wages, and the long road of recovery, and the at-fault driver’s minimum policy may be exhausted long before your bills are paid. When that happens, your own UM/UIM coverage can step in to help cover what remains.
This is exactly why we encourage Lowcountry drivers to carry more than the bare minimum, and to seriously consider underinsured motorist coverage. The cost of adding it is often modest compared to the protection it provides if a catastrophic crash ever occurs.
How “stacking” can multiply your coverage
One of the most powerful and least understood features of South Carolina insurance law is stacking. In certain situations, stacking coverage South Carolina rules allow you to combine the UM or UIM limits from more than one vehicle or policy, which can significantly increase the money available to you.
For example, if you have several vehicles insured on the same policy, you may be able to stack the coverage across those vehicles. In some class-of-insured situations, a person injured in one car may be able to reach coverage under another related policy. The result can multiply your available protection well beyond a single set of limits.
Stacking rules are genuinely technical. Whether stacking applies depends on the specific policy language, how the policies are written, your relationship to the named insured, and the facts of your crash. We do not list every rule here because the right answer depends on your situation. What you should take away is simple: do not assume you are limited to one policy’s limits. An attorney can review every policy that might apply and identify coverage you may not know you have.
A UM/UIM claim is a claim against your own insurer
Here is something that surprises many crash victims. A UM or UIM claim is a first-party claim, which means you are filing it against your own insurance company, not the other driver’s. You pay your premiums faithfully, so it would be reasonable to expect your insurer to treat you fairly when you need help.
Unfortunately, that is not always how it goes. Even your own insurer can act adversarially. It may undervalue your injuries, question your treatment, delay a decision, or push you toward a quick settlement that does not reflect the full harm you suffered. When an insurer crosses the line from tough negotiation into unreasonable conduct, that behavior can raise insurance bad faith concerns under South Carolina law.
Because the company on the other side of your claim is the one you have been paying all along, an honest insurance dispute can feel deeply unfair. You do not have to navigate it alone. Having someone who understands the process and can speak the insurer’s language often changes the tone of the conversation.
How to protect your uninsured motorist claim
Acting promptly is one of the best things you can do. UM and UIM claims carry their own notice requirements and deadlines, and these are separate from the general deadline for an injury lawsuit.
Notice and deadlines
In South Carolina, the statute of limitations for the underlying injury is generally three years, under the general framework of South Carolina Code Section 15-3-530. However, your insurance policy may impose its own notice provisions that require you to inform your insurer of a UM or UIM claim within a certain time. Miss a contractual notice requirement, and you could jeopardize coverage you are otherwise entitled to. This is especially important after a drunk driving crash or a hit-and-run, where evidence and witness memories fade quickly.
Practical steps after a crash
Report the crash to law enforcement and get a copy of the report. Seek medical care and keep records of every visit. Photograph the scene, the vehicles, and your injuries if you can. Notify your own insurer that a UM or UIM claim may be involved, and be careful about giving recorded statements before you understand your rights. You can also learn more about your coverage requirements directly from the South Carolina Department of Insurance.
Finally, keep good records of everything: bills, mileage to appointments, time missed from work, and how the injuries affect your daily life. These details support the full value of your South Carolina uninsured motorist coverage claim.
Frequently asked questions
Is uninsured motorist coverage required in South Carolina?
Yes. South Carolina requires every auto insurance policy to include uninsured motorist coverage at least at the state’s minimum limits. Under the general framework of South Carolina Code Section 38-77-150, this coverage is mandatory, so most drivers already have it even if they have never used it.
What is the difference between UM and UIM coverage?
Uninsured motorist (UM) coverage applies when the at-fault driver has no insurance or flees the scene. Underinsured motorist (UIM) coverage applies when the at-fault driver has insurance, but not enough to cover your full damages. UM is mandatory in South Carolina, while UIM is optional but must be offered to you.
Does a UM/UIM claim count against my own insurance?
A UM or UIM claim is a first-party claim filed with your own insurer, but it arises because another driver caused the crash. Filing a claim to recover for an injury someone else caused is the very purpose of carrying this coverage. If you have questions about how a claim might affect your policy, an attorney can help you understand your specific situation.
What is stacking, and how can it help me?
Stacking is the ability to combine UM or UIM limits from more than one vehicle or policy in certain situations. When stacking applies, it can multiply the coverage available to you. The rules are technical and depend on your policy language and the facts of your crash, so it is wise to have an attorney review every policy that might apply.
Are South Carolina’s minimum limits enough after a serious crash?
Often they are not. The state minimum of 25/50/25 can be exhausted by a single hospital stay or surgery. When the at-fault driver carries only minimum coverage, your own underinsured motorist coverage may be the difference between partial and full recovery for your losses.
How long do I have to file a UM or UIM claim?
The general statute of limitations for the underlying injury in South Carolina is typically three years under the general framework of South Carolina Code Section 15-3-530. However, your policy may require earlier notice of a UM or UIM claim. Because deadlines vary, the safest course is to act promptly and speak with an attorney about your specific policy.
