South Dakota Concussion Injury Lawyer

A concussion is a traumatic brain injury. That sentence carries more legal and medical weight than most people realize when they first leave the emergency room or urgent care clinic after a collision. The symptoms may seem manageable at first, but concussions sustained in car accidents, truck crashes, and similar incidents can evolve into prolonged post-concussion syndrome, cognitive difficulties, chronic headaches, and documented changes in mood and memory that affect every dimension of a person’s life. A South Dakota concussion injury lawyer at Hoy Law understands that what appears to be a “mild” brain injury in the initial medical chart can translate into months of lost work, strained relationships, and ongoing medical expenses that insurance companies are rarely eager to cover fairly.

The challenge with concussion claims in South Dakota is that the injury is invisible on many standard imaging studies. An X-ray shows nothing. Even an MRI may not reveal the functional damage that a neurologist or neuropsychologist would detect through careful evaluation. Insurance adjusters know this, and they use it. They point to clean imaging results and argue the injury is minor or exaggerated. Experienced concussion injury attorneys know how to counter these arguments with the right medical evidence, the right experts, and a thorough understanding of how traumatic brain injuries are actually diagnosed and treated.

At Hoy Law, with over 150 years of combined experience representing accident victims across South Dakota, our attorneys approach concussion cases with the same rigor applied to any serious injury claim. We dig into the medical evidence, work with qualified specialists, and challenge the assumptions that insurance companies use to minimize these injuries. If a collision caused your concussion, the responsible parties should be held accountable for the full extent of what you have lost.

How Concussion Cases Arise in South Dakota Accident Claims

• Rear-End Car Collisions: Sudden deceleration from rear-end crashes is among the most common causes of concussion injuries in South Dakota, including accidents on Interstate 90, Interstate 29, and US-81 near Sioux Falls. The brain strikes the interior of the skull even when there is no direct blow to the head.
• Semi-Truck and Commercial Vehicle Crashes: The mass and force involved when a commercial truck strikes a passenger vehicle creates violent head movement. Concussions from truck accidents often occur alongside other serious injuries and may be missed initially in the chaos of trauma treatment.
• Intersection and T-Bone Collisions: Side-impact crashes at urban intersections and rural highway crossings expose occupants to lateral head motion that the neck and skull are poorly equipped to absorb, producing concussive force even at moderate speeds.
• Rollover Accidents: Rollover crashes, which are more common on South Dakota’s rural highways and during winter weather conditions, frequently result in head contact with the vehicle interior and significant rotational brain movement, a known mechanism for concussion and more severe traumatic brain injury.
• Motorcycle Crashes: Motorcyclists who sustain head impacts even while wearing helmets can suffer concussions. Helmets reduce the risk of catastrophic brain injury but do not eliminate concussive force. These cases require careful medical documentation to connect the accident to the neurological symptoms.
• Workplace and Construction Accidents: Falls, equipment strikes, and other on-the-job incidents cause a significant share of concussion injuries in South Dakota’s agriculture, construction, and industrial sectors. These cases may involve both workers’ compensation claims and third-party liability claims against equipment manufacturers or contractors.

Why Hoy Law Handles Concussion Claims Differently

Hoy Law is home to the only board-certified trucking accident lawyers in South Dakota, a distinction that reflects the firm’s depth of knowledge in the most complex accident litigation this state produces. That same depth applies to concussion injury cases, where understanding the mechanics of how the injury happened, gathering the right evidence immediately, and retaining qualified medical experts are decisions that shape the entire trajectory of the claim.

Our attorneys have spent years representing injury victims in Sioux Falls and across South Dakota. We know how insurance adjusters evaluate these claims and where they look for weaknesses in the medical record. A concussion that goes undocumented in the first 24 to 72 hours becomes a target. A gap in treatment becomes an argument that the injury resolved. Our legal team moves quickly to preserve evidence, coordinate with medical providers, and build a record that reflects the real, ongoing impact of the injury rather than the sanitized version the insurance company prefers.

Because we understand South Dakota courts, local juries, and the procedural expectations of courts across the state, our attorneys can present concussion cases in ways that resonate with fact-finders who may not initially appreciate the seriousness of a brain injury that leaves no visible mark. That local knowledge, combined with our firm’s resources, means that clients facing low settlement offers have a team that is fully prepared to take their case through litigation if that is what it takes.

What Concussion Victims and Families Should Do After a South Dakota Accident

The medical record that exists in the first days after an accident will shape the concussion claim for its entire life. Anyone who has hit their head in a crash, experienced a sudden jolt, lost consciousness even briefly, or developed headaches, confusion, or nausea in the aftermath of a collision should seek medical evaluation immediately. Emergency departments at Sanford USD Medical Center and Avera McKennan Hospital in Sioux Falls, Regional Health facilities in Rapid City, and urgent care clinics across South Dakota are equipped to begin the diagnostic process. Tell treating providers specifically about head contact or head movement and all neurological symptoms. Do not minimize symptoms to appear less injured than you are.

Follow-up care matters just as much as the initial evaluation. A single emergency room visit that produces normal imaging is not the end of the medical story for a concussion. Seek evaluation from a neurologist or a concussion specialist if symptoms persist beyond a few days. Neuropsychological testing documents the cognitive effects of the injury in ways that imaging cannot. This documentation is critical evidence in a concussion claim. Insurance companies will closely examine whether you sought consistent, appropriate follow-up care. Gaps in treatment are used to argue recovery, even when symptoms are real and ongoing.

Report the accident to law enforcement and obtain the crash report. In South Dakota, accident reports are handled through the South Dakota Department of Public Safety, and copies can be requested through the appropriate law enforcement agency. Photograph the vehicles, the scene, and any visible injuries. Preserve dashcam footage, witness contact information, and anything else that documents the conditions and cause of the crash. For an adult, South Dakota’s statute of limitations for personal injury claims generally allows three years from the date of the accident to file suit, but waiting does not serve the claim. Evidence degrades, witnesses become harder to locate, and insurance companies use delay as a negotiating advantage. Contact a concussion injury attorney in South Dakota as early in the process as possible.

Calculating What a Concussion Injury Is Actually Worth

One of the most consequential decisions in any concussion case is how damages are valued and presented. Insurance companies consistently try to anchor these claims at the cost of the initial medical treatment, which in a concussion case may be relatively modest compared to a fracture or surgical injury. But the real economic impact of a prolonged concussion frequently extends far beyond what the early bills reflect.

Lost wages during recovery can be substantial when someone cannot work, drive, concentrate, or tolerate screen time. Post-concussion syndrome, which affects a meaningful percentage of people who sustain concussions in accidents, may involve symptoms lasting months or longer. Documented cognitive difficulties, chronic headaches, sleep disruption, and mood changes can affect job performance, earning capacity, and quality of life well beyond the initial recovery period. These are compensable damages, but only if they are properly documented and argued.

Compensation in a South Dakota concussion case may include past and future medical expenses, lost earnings and reduced earning capacity, the cost of occupational therapy or neuropsychological rehabilitation, and non-economic damages for pain, suffering, and the effect the injury has had on daily life and relationships. South Dakota applies contributory negligence. If an injured person’s negligence was slight in comparison with the negligence of the other party, they can still recover, with damages reduced in proportion to their contributory negligence. If it was more than slight, recovery is barred. At Hoy Law, our attorneys work to make sure that fault allocation reflects the actual facts rather than the insurance company’s preferred narrative.

Questions People Ask About South Dakota Concussion Injury Claims

How do I prove I have a concussion if my MRI and CT scan came back normal?

Normal imaging results do not rule out a concussion. Concussions are a functional brain injury diagnosed based on symptoms and mechanism of injury, not solely on imaging. Neuropsychological testing, symptom diaries, physician opinions, and neurologist evaluations can all document the existence and severity of a concussion and its effects. Functional MRI and other advanced imaging tools may reveal abnormalities that standard imaging misses. An attorney working on your claim can coordinate with qualified medical experts to build this documentation.

What is post-concussion syndrome and does it affect my claim?

Post-concussion syndrome refers to persistent concussion symptoms that continue beyond the expected recovery period, sometimes for months. Symptoms can include ongoing headaches, cognitive difficulties, light and noise sensitivity, sleep problems, depression, and anxiety. When an accident causes post-concussion syndrome, the damages associated with the claim expand significantly to include prolonged medical treatment, extended lost wages, and greater non-economic damages. These cases require thorough medical documentation and often the involvement of neurological specialists.

The insurance company says my concussion was minor. What should I do?

Insurance companies routinely characterize concussion injuries as minor as a strategy to reduce settlement value. The severity of a concussion is not determined by the insurance adjuster. It is determined by medical professionals evaluating your symptoms, your functional limitations, and your recovery trajectory. Do not accept this characterization without a thorough medical evaluation and legal advice. An attorney can challenge the insurer’s position with the right expert opinions and documented evidence of your actual losses.

Can I still recover compensation if I was not wearing a seatbelt during the crash that caused my concussion?

South Dakota follows a contributory negligence rule. An injured person can still recover if their own negligence was slight in comparison with the negligence of the at-fault party, but the damages are reduced in proportion to the injured person’s contributory negligence. Not wearing a seatbelt could be raised by the defense to argue that you bear some share of responsibility for the severity of your injuries. However, this does not automatically bar recovery. The specific facts of the accident and how fault is allocated matter. An attorney can evaluate how this issue is likely to affect your specific claim.

How long does it typically take to resolve a concussion injury case in South Dakota?

The timeline depends heavily on the severity of the injury, how long recovery takes, and how aggressively the insurance company contests the claim. For ongoing symptoms, it is often advisable to wait until maximum medical improvement is reached before finalizing a settlement, so the full extent of long-term damages is known. Cases that settle without litigation may resolve within several months to over a year. Cases that proceed through litigation in South Dakota courts take longer. Your attorney can give you a more specific estimate based on the facts of your case.

What if I did not notice concussion symptoms until days after the accident?

Delayed symptom onset is well-documented with concussion injuries. Symptoms sometimes do not appear or worsen until 24 to 72 hours after the impact. This is a recognized medical phenomenon, not evidence that the injury was not caused by the accident. It is important to seek medical care as soon as symptoms appear, even if days have passed, and to explicitly connect those symptoms to the crash when speaking with your healthcare providers. Documentation of the timeline is important.

I was driving a commercial vehicle when the accident happened and I suffered a concussion. Do I have a claim?

Whether you were operating a commercial vehicle at the time of a crash does not eliminate your right to seek compensation if another party was responsible for causing the accident. The situation may be more complex if workers’ compensation coverage applies, and there may also be third-party liability claims available against the at-fault driver or other responsible parties. These cases require careful analysis of which claims are available and how they interact with each other.

Can a concussion affect my ability to work in a professional or technical field, and can that be compensated?

Yes. Concussion-related cognitive difficulties, including problems with concentration, memory, word retrieval, and tolerance for visually demanding tasks, can significantly impair someone’s ability to perform professional, technical, or administrative work. Vocational experts and neuropsychologists can document these limitations and quantify the effect on earning capacity. Reduced earning capacity is a recognized category of compensable damages in South Dakota personal injury cases.

What if the truck driver’s employer denies any liability for the crash that caused my concussion?

Denial of liability by a trucking company is a common initial position, not a final determination of your rights. In many truck accident cases, multiple parties share responsibility, including the driver, the company, the cargo owner, and others. Evidence including driver logs, electronic logging data, black box records, maintenance records, and driver qualification files can establish liability even when the company initially disputes it. Hoy Law has specific experience handling this type of complex truck accident litigation in South Dakota.

Does health insurance cover treatment for a concussion while my personal injury claim is pending?

Health insurance typically covers medically necessary treatment regardless of whether a personal injury claim is pending. However, your health insurer may have a right to reimbursement from any eventual settlement or judgment, known as a subrogation interest. An attorney can help you understand how your health insurance and any personal injury protection coverage interact with your claim, and negotiate to reduce the subrogation amount if possible when your case resolves.
