In most cases, the statute of limitations for 18-wheeler accidents in SC is three years from the date of the crash, set by Section 15-3-530 of the South Carolina Code of Laws. That is the number nearly every law firm page gives you, and it is correct as far as it goes. The deadline that decides more truck cases is quieter: federal rules let a trucking company erase the driver’s logs six months after the wreck, on schedule and entirely legally.
Three years is the outside limit, not the working deadline
The three-year clock is the date by which a lawsuit has to be filed in court. It is not the date an insurance company has to pay, and nothing in it pushes an adjuster to move any faster. Miss it and the claim is over, however clear the other side’s fault was. That same three-year rule drives the general personal injury deadlines in South Carolina, which is why so many pages about truck wrecks simply repeat the car-wreck answer.
A collision with a tractor-trailer is not a car wreck with a bigger vehicle. There can be several parties on the other side: the driver, the motor carrier that employed the driver, the company that loaded the trailer, a maintenance contractor, the broker who arranged the freight. Each one is reached through records that someone else holds, and most of those records are kept only as long as federal rules require. Sorting out who belongs in a case is work a Charleston 18-wheeler accident lawyer starts long before any filing deadline is near.
The deadlines that run shorter than three years
Three years is the default. Several common situations are not the default.
- A government vehicle was involved. A claim against a state agency, a county or a city falls under the South Carolina Tort Claims Act, which carries its own notice requirements and a shorter window than an ordinary injury claim.
- Someone died. A wrongful death action is brought by the personal representative of the estate, and its clock runs from the date of death rather than the date of the collision. South Carolina wrongful death claims also decide who may recover, which is not always who you would expect.
- You were working when it happened. Delivery drivers and port haulers often have two cases at once: a workers’ compensation claim and a third-party injury claim. The workers’ compensation side has its own notice requirement and its own deadline, and both can expire while the injury claim is still open.
- The truck’s insurance is not enough. Turning to your own uninsured and underinsured motorist coverage brings your policy’s notice and cooperation terms into play. Those are contract deadlines, not statutes, and they are often measured in days.
- The injured person is a child. Deadlines for a minor are calculated differently, and the calculation turns on the child’s age and the type of claim.
What the statute of limitations for 18-wheeler accidents in SC does not cover
A filing deadline says nothing about how long the proof lasts. Interstate carriers answer to the Federal Motor Carrier Safety Administration, whose rules set how long a company has to keep each kind of record. When that period ends, routine deletion is not misconduct. It is compliance. These are the windows that matter most after a tractor-trailer crash.
| Evidence | How long it usually survives |
|---|---|
| Hours-of-service logs and electronic logging device data (the ELD is the in-cab unit that records a driver’s hours) | Six months of carrier retention under federal rules |
| Driver vehicle inspection reports, which show defects the driver noted before and after a trip | About three months |
| Post-crash drug and alcohol testing of the driver | Hours, not months; federal rules set tight windows measured from the crash |
| Engine control module data, the tractor’s onboard record of speed, braking and throttle | Until the truck is repaired, put back in service or sold |
| Dashcam video and footage from nearby businesses or terminals | Days to a few weeks on a recording loop |
| Witness memory and current contact information | Unpredictable, and it only gets worse |
Set that against a three-year filing deadline and the pattern is hard to miss. The records that show why the truck hit you can be gone before the first anniversary of the crash, while the deadline to sue still has more than two years left on it.
The letter that stops the deletion
The tool for this is a preservation letter, sometimes called a spoliation letter, after the legal term for destroying evidence that belongs in a case. It goes to the motor carrier and its insurer, identifies the tractor and trailer by unit number, and lists the specific records that have to be held: logs and ELD downloads, the engine control module, inspection and maintenance files, dispatch records, the driver’s qualification file, and any camera footage. Once a carrier has that letter, erasing those records on its ordinary schedule becomes the carrier’s problem rather than yours.
Sending it means knowing who the carrier and insurer are. That usually comes off the TR-310, South Carolina’s uniform traffic collision report form, which the investigating agency completes and then releases. Requesting that report early is often the first concrete step in what to do after a truck accident in South Carolina.
Two other clocks running in the background
The first is your medical record. A long gap between the crash and your first visit hands an adjuster an argument, and only a medical professional can evaluate what the collision did to your body. That is a question for a doctor, not for a lawyer or a website. The second is fault. South Carolina’s comparative negligence rule lets a jury assign you a share of the blame and cut what you recover, and past a certain share you recover nothing at all. That argument gets built out of the same evidence that expires: logs, engine data, and video from the I-26 and I-526 merge or a Rivers Avenue driveway. Showing what the other driver was actually doing, including how a distracted driving claim is proven, depends on records other people control.
Asking the question before the six-month records go
Grooms Law Firm is a solo practice by design: you work directly with Taylor Grooms, not a case manager, and the attorney who evaluates the case is the one who negotiates it. Direct access means the lawyer returns the call, not that anyone is reachable at any hour. The initial consultation is free, the fee agreement is in writing before work begins, and there is no fee unless we recover compensation for you. If a claim is not worth pursuing, you will hear that too.
This article is general legal information about South Carolina deadlines, not legal advice about your situation, and nothing here creates an attorney-client relationship. Neither reading it nor sending a message through this site does that. If a tractor-trailer was involved in your crash anywhere in the Lowcountry, you can contact Grooms Law Firm to ask which deadlines apply to you and whether a preservation letter still has anything left to preserve.
Frequently asked questions
Can you sue if an 18-wheeler hits you?
Yes. An injured person in South Carolina can bring a claim against the truck driver and, in many situations, against the motor carrier that employed the driver or others in the chain, such as a company that loaded the trailer. Whether a particular claim is worth bringing depends on the evidence, the available insurance and the facts of the crash. A lawyer can only tell you after reviewing those specifics.
How long after a car accident can you sue in South Carolina?
Most personal injury lawsuits in South Carolina have to be filed within three years of the crash under Section 15-3-530 of the South Carolina Code of Laws. Claims involving a government entity, a death, workers’ compensation or an injured child follow different rules, and some of those windows are shorter. If any of those apply, the three-year figure is the wrong one to plan around.
Can you sue for an injury that happened years ago?
Sometimes, but it depends on the type of claim and when the clock started. Once the applicable deadline passes, a court will normally dismiss the case no matter how strong the facts are. Because a few situations change the start date or pause the clock, an older crash is still worth asking about rather than assuming it is closed.
How long does a trucking company have to keep the driver’s logs?
Under Federal Motor Carrier Safety Administration rules, carriers generally keep hours-of-service records and electronic logging device data for six months. Driver vehicle inspection reports are held for a shorter period. After those windows, deleting the records is routine compliance rather than wrongdoing, which is why a preservation letter sent early matters so much in a truck case.
What is a spoliation letter in a truck accident case?
It is a written notice to the trucking company and its insurer that identifies the vehicles involved and lists the records they must preserve: logs, engine control module data, maintenance and inspection files, dispatch records and camera footage. It does not file anything with a court. Its purpose is to take away the excuse that evidence was destroyed in the ordinary course of business.
