Worth knowing in South Dakota

South Dakota uses an unusual 'slight/gross' negligence comparison used by very few states; how fault is weighed deserves careful review.

The deadline to file in South Dakota

South Dakota generally gives injured people 3 years from the date of a crash to file a personal-injury lawsuit. Miss it and the court will almost always refuse the case, no matter how strong it is. The clock can run differently for claims involving a government vehicle, an injured minor, or a death, so the single most important early step is to confirm your actual deadline.

How South Dakota handles fault

South Dakota uses a "slight/gross" negligence comparison: you can generally recover only if your own negligence was slight relative to the other party's. Few states use this rule, so how blame is weighed deserves careful review.

No-fault vs. at-fault in South Dakota

South Dakota is an at-fault (tort) state. The driver who caused the crash — and their insurer — is responsible for the resulting damages, so establishing fault is central to your claim.

Minimum insurance in South Dakota

Drivers in South Dakota must carry at least $25,000 / $50,000 in liability coverage. Those minimums are often far below what a serious injury actually costs, which is why your own uninsured/underinsured motorist coverage can end up being the coverage that matters most.
