Car insurance in South Dakota

What South Dakota law requires you to carry

Every car registered and driven in South Dakota has to be backed by proof of financial responsibility, and for almost everyone that means a liability auto policy. The state's minimum limits are:

• $25,000 bodily injury per person — the most the policy pays for injuries to any one person you hurt
• $50,000 bodily injury per crash — the most it pays in total for everyone injured in one accident
• $25,000 property damage per crash — for the other driver's vehicle, plus fences, mailboxes, signs and anything else you damage

You'll see this written as 25/50/25. On top of that, your policy must include uninsured motorist (UM) and underinsured motorist (UIM) coverage — South Dakota is one of the states where those are not optional (see SDCL 58-11-9).

Two things the minimums do not do. They never pay a cent toward your own car — that's collision and comprehensive, which are optional under state law but required by any lender or leasing company. And they are limits, not budgets: if you injure someone badly and the bills run past $25,000, the insurer pays up to the limit and the rest is your problem, including your wages and savings. That's the single best argument for buying more than the floor.

Personal injury protection (PIP) is not required in South Dakota, and the state is not a no-fault state. Your own medical bills after a crash are handled by health insurance, by optional medical payments coverage, or by a claim against the at-fault driver.

Regulator: the South Dakota Division of Insurance, part of the Department of Labor and Regulation.

Fault, and how a claim actually plays out

South Dakota is an at-fault (tort) state. Whoever caused the crash — through their insurer — is responsible for the damage. There's no no-fault layer where each driver simply claims from their own company regardless of blame.

After a collision you generally have three routes:

1. Claim against the other driver's liability insurance (a third-party claim). This covers your injuries and your vehicle damage if they were at fault, up to their limits.
2. Claim on your own policy (a first-party claim), if you carry collision, comprehensive or medical payments. Your insurer pays, you owe the deductible, and the insurer then tries to recover from the at-fault driver's company — a process called subrogation. If it succeeds, your deductible usually comes back to you.
3. Sue, if the insurer denies liability or the offer doesn't come close to covering the loss. Deadlines for filing suit are set by statute, so ask a South Dakota attorney early rather than late.

Because fault decides who pays, the two insurers will each form their own view of it, and they don't always agree. Adjusters weigh the police report, photos, vehicle damage patterns, skid marks, witnesses and dashcam footage, and they often assign percentages of blame rather than a clean all-or-nothing answer. How a split-fault case is treated — including whether a partly-to-blame driver recovers anything, and how much — is governed by South Dakota's comparative-fault law and can turn on the specific facts, so get advice if an insurer is pinning part of the blame on you.

Practical steps that protect a claim: call law enforcement and get the report number, photograph the scene and both vehicles before anything moves, exchange insurance details, note any witnesses, get checked out medically even if you feel fine, and report the crash to your own insurer promptly even when you're certain the other driver caused it. Keep every repair estimate, medical bill and receipt — a documented claim settles far more smoothly than a remembered one.

UM and UIM: the coverage South Dakota won't let you skip

This is where South Dakota differs from most states, and it's worth understanding rather than just paying for.

Uninsured motorist (UM) covers you when the at-fault driver has no insurance at all, or hits you and disappears. Underinsured motorist (UIM) covers you when the at-fault driver is insured but their limits run out before your injuries are paid for — a realistic scenario when their policy stops at $25,000 per person and you've had surgery.

Under SDCL 58-11-9, every auto policy issued in South Dakota must include UM and UIM equal to the policy's bodily injury limits. That has a consequence people miss: because the two are tied together, raising your liability limits automatically raises the protection you have for yourself and your passengers. Buying 100/300 liability instead of the 25/50 minimum doesn't only protect the people you might injure — it quietly buys you a much bigger safety net if an uninsured or badly-underinsured driver injures you.

A few notes on how UM/UIM works in practice:

• It pays for bodily injury — medical costs, lost income, pain and suffering — to you, family members in your household and your passengers.
• UIM is normally excess: the at-fault driver's insurer pays first, and your UIM makes up the shortfall up to your limit.
• Your own insurer is the one paying, so notify it quickly, cooperate with its investigation, and don't sign a settlement or release with the other driver's insurer before talking to your own company — doing so can jeopardize a UIM claim.
• Hit-and-run and phantom-vehicle claims have their own reporting expectations. Report to police straight away.

Optional coverage that's usually worth the money

None of these are required by South Dakota law, but each fills a real gap the minimum policy leaves open.

• Collision — repairs your car after you hit something or roll it, whoever's at fault. Required by every auto lender and lessor.
• Comprehensive — the non-collision stuff, and in South Dakota that's a long list: hail, high winds, flooding, fire, theft, vandalism, falling branches, and the deer and livestock strikes that are a routine hazard on rural highways at dawn and dusk. An animal collision is a comprehensive claim, not a collision claim.
• Higher liability limits — the cheapest serious upgrade on the page, and under South Dakota's UM/UIM rule it raises your own injury protection at the same time.
• Medical payments (MedPay) — a small pot of money that pays medical bills for you and your passengers quickly, no fault determination needed. Useful if you have a high-deductible health plan, and it covers passengers who may not.
• Rental reimbursement and roadside assistance — low-cost add-ons that matter more where the nearest body shop or tow truck is an hour away.
• Gap coverage — if you financed a new vehicle, this pays the difference between what you owe and what the car was worth when it's totaled.
• Umbrella policy — sits above your auto and home liability for a catastrophic claim; worth pricing if you have assets to protect.

Two choices shape what you'll pay: your deductible (set it at a level you could cover from savings tomorrow, not a theoretical best case) and whether your comprehensive and collision are actual cash value or replacement-style settlements. Also ask specifically how the policy treats windshield glass — a separate or waived glass deductible is common and matters on gravel roads.

Rules and habits South Dakota drivers trip on

Carrying proof. You must be able to show proof of financial responsibility when a law enforcement officer asks and when you deal with the vehicle's registration. Keep the current card in the glovebox or on your phone, and swap it out the day the renewal arrives — an expired card for an active policy is an avoidable roadside argument.

Letting coverage lapse. A lapse doesn't just leave you uninsured on the road; it tends to follow you into your next quote, because insurers treat continuous coverage as a rating factor. If you're selling a car or putting one away for the winter, talk to your agent before you cancel — a storage or comprehensive-only arrangement is usually a better answer than nothing. Driving without the required coverage can bring court penalties and the loss of your license and registration privileges until you file proof of future financial responsibility with the state, and that filing requirement can hang around for years.

Assuming the minimum is enough. 25/50/25 was never designed to cover a serious injury crash. A single hospitalization can pass the per-person bodily injury limit, and modern vehicles pass the $25,000 property damage limit easily. Above the limit, you're personally exposed.

Credit. South Dakota insurers may use credit-based insurance scores when pricing and underwriting your policy. It's not your lending credit score, but it is built from your credit file — so errors on your credit report can cost you money on car insurance. Check your report, dispute mistakes, and re-shop after your credit improves.

Who's on the policy. Insurers expect household members of driving age and regular drivers of your car to be disclosed. A teenager with a learner's permit, a roommate who borrows the truck, or a college student who keeps the car at school all need to be mentioned. Silence here is the most common cause of an ugly surprise at claim time.

Business use. Commuting is one thing; delivery driving, rideshare or hauling for a farm or business can fall outside a personal auto policy. Ask before you start, not after.

What it costs, for context. Across the whole country, the NAIC put the average expenditure for liability, collision and comprehensive combined at $1,158 per insured vehicle in 2023. Your own price depends on your vehicle, your record, where you park it, your limits and deductibles and your insurer's own rating — which is exactly why quotes from several companies on identical limits are the only honest comparison.

How to complain to the South Dakota Division of Insurance

Car insurance in South Dakota is regulated by the Division of Insurance within the Department of Labor and Regulation. If a claim is being delayed, underpaid or denied without a clear explanation, or you have a dispute with an agent or adjuster, you can bring it to them.

Step 1 — exhaust the insurer first. Ask for the written reason for the decision and the specific policy language relied on, then use the company's own appeal or supervisor review. Put requests in writing (email is fine) and keep copies.

Step 2 — assemble the file. Policy number, claim number, dates, the names of everyone you spoke to, your correspondence, the denial letter, estimates, bills and photos. A complaint with documents attached moves faster than one without.

Step 3 — file with the Division. The Division's complaint process page explains who you can complain about — insurance companies, HMOs, producers (agents), adjusters and other regulated entities — and how to submit. There's an online submission route and a printable complaint form if you'd rather mail it. General consumer resources, including licence verification for companies and agents, sit on the Division's consumer information page. You can also reach the Division by phone at 605.773.3563 to talk through an issue before filing.

What to expect. The Division contacts the company, requires a response and reviews whether the policy and South Dakota insurance law were applied correctly. It can press an insurer to correct a mistake and can act on licensees who violate the law. What it generally cannot do is decide a contested question of fact or fault for you, or act as your lawyer — if the real dispute is how much your injury claim is worth, or who caused the crash, that's a matter for negotiation or the courts. Filing a complaint doesn't stop any legal deadline from running, so don't let it replace legal advice in a serious injury case.

The Division's site is also the place to verify that a company or agent is licensed in South Dakota before you hand over money — a two-minute check that stops most insurance scams cold.
