South Dakota car insurance laws require every driver and vehicle owner to carry liability coverage of at least $25,000 for one person’s bodily injury, $50,000 for bodily injury when more than one person is hurt, and $25,000 for property damage. Policies must also include uninsured and underinsured motorist coverage. Driving without coverage is a misdemeanor, and the penalties reach beyond a fine to jail time and a suspended license.
Minimum Liability Limits
State law sets the floor at what insurers call 25/50/25:1South Dakota Legislature. South Dakota Code 32-35-70 – Conditions of Owners Policy Coverage and Amount
- $25,000 for bodily injury or death of one person in a single accident
- $50,000 for bodily injury or death of two or more people in a single accident
- $25,000 for damage to another person’s property in a single accident
Liability only pays for what you do to other people and their property. It does not touch your own medical bills or your own vehicle. The minimums are enough for a minor crash. A serious collision with hospital stays or a totaled car can blow through them quickly, and anything above the policy limit becomes your personal debt.
Liability insurance is the usual way to meet South Dakota’s financial responsibility requirement, but it is not the only one. A $50,000 certificate of deposit or a certificate of self-insurance also qualifies.2South Dakota Legislature. South Dakota Code 32-35-113 – Maintenance of Financial Responsibility Violation as Misdemeanor Almost everyone buys a policy.
Uninsured and Underinsured Motorist Coverage
Every auto liability policy sold in South Dakota must include uninsured motorist (UM) coverage. UM limits have to match your bodily injury limits, up to a cap of $100,000 per person and $300,000 per accident. You can request higher limits if you want them.3South Dakota Legislature. South Dakota Code 58-11-9 – Motor Vehicle Insurance Uninsured Motorist and Hit-and-Run Coverage UM pays when the at-fault driver has no insurance or disappears from the scene in a hit-and-run.
Underinsured motorist (UIM) coverage is also mandatory and works the same way. It must equal your bodily injury limits, with the same $100,000/$300,000 cap unless you ask for more.4South Dakota Legislature. South Dakota Code 58-11-9.4 – Underinsured Motorist Coverage to Be Available With Liability Policies UIM applies when the other driver carries insurance but not enough to cover your losses.
There is a catch worth knowing. South Dakota uses a setoff rule for UIM. Your insurer subtracts whatever the at-fault driver’s liability policy already paid before calculating your UIM benefit.5South Dakota Legislature. South Dakota Code 58-11-9.5 – Payment to Insured for Portion of Judgment Not Collected From Underinsured Motorist If your UIM limit is $50,000 and the other driver’s insurer paid $25,000, your UIM benefit tops out at $25,000. The only way to build real cushion is higher UIM limits.
Penalties for Driving Without Insurance
Failing to maintain financial responsibility is a Class 2 misdemeanor.2South Dakota Legislature. South Dakota Code 32-35-113 – Maintenance of Financial Responsibility Violation as Misdemeanor The maximum penalty is 30 days in the county jail, a $500 fine, or both.6South Dakota Legislature. South Dakota Code 22-6 – Authorized Punishments On top of the criminal case, the state can suspend your driver’s license and your vehicle registration until you provide proof of valid coverage.
Getting a license back after a no-insurance suspension usually means filing an SR-22. The SR-22 is not insurance. It is a form your insurer files with the state certifying that you carry at least the minimum required coverage. You generally need to keep it on file for up to three years, and any lapse during that window can trigger an automatic re-suspension. The filing fee from your insurer is usually small, but the premium itself climbs once you need the filing.
Proof of Insurance
You must be able to show proof of coverage whenever a law enforcement officer asks, during a traffic stop or at a crash scene.7South Dakota Division of Insurance. Automobile Insurance Acceptable proof includes a copy of the policy, an insurance identification card showing the insurer’s name, policy number, effective date, and expiration date, or written confirmation from the insurer that you were covered at the time.8South Dakota Legislature. South Dakota Code 32-35-119 – Written Evidence of Insurance
Electronic proof counts. A digital insurance card on your phone works as long as it carries the same information as the paper version.8South Dakota Legislature. South Dakota Code 32-35-119 – Written Evidence of Insurance Handing over your phone means the officer is holding it, so have the document ready to open before you pull it out.
Reporting an Accident
If you are in a crash that causes any injury, death, or property damage of $1,000 or more, you must notify the nearest law enforcement officer immediately by the quickest available means. Failing to report a qualifying accident is itself a Class 2 misdemeanor.9South Dakota Legislature. South Dakota Code 32-34-7 – Duty to Give Immediate Notice of Accident to Law Enforcement Officer Pull over when safe, check for injuries, and call 911 or the local sheriff’s office.
You should also notify your own insurance company promptly, even if the other driver was clearly at fault. Delay can complicate UM and UIM claims and give the insurer a reason to question coverage.
How Fault Affects What Insurance Pays
South Dakota is a fault state. The driver who caused the accident is financially responsible for the other party’s injuries and property damage, which is where liability insurance does its work.
Shared fault is handled differently here than in most states. Instead of the common 50-percent bar, South Dakota uses a slight-gross standard: you can only recover damages if your own negligence was slight compared with the other driver’s.10South Dakota Legislature. South Dakota Code 20-9-2 – Comparative Negligence Reduction of Damages If a jury finds your fault was more than slight, you recover nothing. If it qualifies as slight, your award is reduced in proportion to your share.
This is one of the strictest comparative negligence rules in the country. Even a moderate share of fault can wipe out a claim. Higher liability, UM, and UIM limits on your own policy give you more to fall back on when a fault allocation does not go your way.
When an Insurer Can Cancel or Nonrenew
Once an auto policy has been in force for 60 days, South Dakota narrows the grounds for cancellation to three: nonpayment of premium, suspension or revocation of the driver’s license or vehicle registration during the policy period, or removal from the state’s 24/7 sobriety program for noncompliance.11South Dakota Legislature. South Dakota Code 58-11-46 – Reasons for Cancellation of Automobile Insurance Policy
Inside the first 60 days of a new policy, the rules are looser. The insurer can cancel for any reason with proper notice before the 60-day window closes.12South Dakota Legislature. South Dakota Code 58-11-47 – Reasons for Cancellation Not Applicable to Automobile Policy in Effect Less Than Sixty Days A brand-new policy carries less protection against cancellation than one you have held for a while.
Nonrenewal is a separate decision made at the end of a term. The insurer must give written notice before the policy expires so you have time to find a replacement. If you believe a cancellation or nonrenewal was unfair, you can file a complaint with the South Dakota Division of Insurance.13South Dakota Department of Labor and Regulation.

Optional Coverages Worth Considering
State law only requires liability, UM, and UIM. A few optional coverages matter more here than in states with gentler fault rules, because the slight-gross standard can leave you with no claim against the other driver.
- Collision pays to repair or replace your own vehicle after an accident regardless of fault. If your negligence is found to be more than slight, this becomes your only route to getting the car fixed.
- Comprehensive covers non-collision damage such as hail, theft, vandalism, and animal strikes. South Dakota’s weather and rural roads make it relevant.
- Medical payments (MedPay) covers medical expenses for you and your passengers regardless of fault, which fills the gap when the slight-gross rule blocks recovery from the other driver.
None of these is legally required. Lenders usually require collision and comprehensive on a financed or leased vehicle. Even without a lender in the picture, a small share of fault can leave you with no claim against the other driver and only your own policy to fall back on.
