Duty of Care
Every driver has a legal obligation to operate their vehicle safely. This includes following traffic laws, staying alert, and adjusting for road conditions such as traffic, weather, and visibility.
Breach of Duty
A breach occurs when a driver fails to meet that standard of care. Common examples include:
- Speeding
- Running a red light or stop sign
- Distracted driving, including texting
- Driving under the influence
- Failing to yield
Causation
It is not enough that a driver acted carelessly. That behavior must have directly caused the accident. For example, if a driver runs a red light and collides with another vehicle, that action is the cause of the crash.
Damages
You must also show that the accident resulted in actual harm. This may include:
- Medical expenses
- Lost income
- Property damage
- Pain and suffering

What Evidence Is Used to Prove Fault
Insurance companies and attorneys rely on evidence to determine negligence and fault. This often includes:
- Police accident reports
- Photos and videos from the scene
- Witness statements
- Vehicle damage patterns
- Medical records
- Traffic camera or dashcam footage
The stronger the evidence, the easier it is to establish who was at fault.
South Dakota Contributory Negligence Rule
Unlike virtually every other state in the nation, South Dakota has not changed to a comparative negligence standard. Instead, it retains the traditional model, called contributory negligence. That legal doctrine allows a defendant to avoid responsibility for their negligence if they prove that the plaintiff’s negligence was “more than slight” when compared to the negligence of all other parties involved in the incident. South Dakota law does not define the term “slight” and leaves it up to the jury to determine the amount of each party’s negligence in comparison to the others. If a plaintiff’s negligence is “more than slight” they lose their claim. If a plaintiff’s negligence is “slight” or “less than slight” a jury can still give a verdict in the plaintiff’s favor, but may reduce that verdict by some amount to account for the plaintiff’s negligence.
| If the Plaintiff’s negligence compared to that of Defendant(s) is: | Then a Jury Verdict results in: |
| 0% | Full Plaintiff’s verdict |
| “Less than slight” or “Slight” | Plaintiff’s verdict reduced by some amount for the plaintiff’s negligence |
| “More than slight” | Defense verdict |
How is fault determined in a Sioux Falls car accident?
Fault is determined based on negligence. Investigators look at police reports, witness statements, accident scene evidence, and traffic laws to decide which driver failed to use reasonable care.
What is South Dakota’s “slight vs. gross negligence” rule?
South Dakota follows a unique rule where you can recover damages only if your negligence is considered “slight” compared to the other party’s “gross” negligence. If your fault is more than slight, you may be barred from recovering compensation.
Can I still recover damages if I was partially at fault?
Unlike virtually every other state in the nation, South Dakota has not changed to a comparative negligence standard. Instead, it retains the traditional model, called contributory negligence.

What evidence is used to prove fault in a car accident?
Common evidence includes:
- Police accident reports
- Photos and videos from the scene
- Witness statements
- Traffic camera footage
- Vehicle damage analysis
- Expert accident reconstruction
Does the insurance company decide who is at fault?
Insurance companies make an initial determination, but their decision is not final. Fault can be disputed, and ultimately, a judge or jury may decide if a case goes to court.
What if multiple drivers are involved in the accident?
Each driver’s actions are evaluated individually. Fault may be shared, but under South Dakota law, you must still prove your role was only slight compared to others to recover compensation.
How long does it take to determine fault after an accident?
It can take anywhere from a few days to several months depending on the complexity of the case, the availability of evidence, and whether liability is disputed.
