Car Insurance in South Carolina
South Carolina is an at-fault insurance state — meaning the driver who causes an accident is responsible for paying the other party's damages through their liability insurance. State law requires a minimum of 25/50/25 liability coverage plus mandatory Uninsured Motorist coverage at matching limits. South Carolina drivers pay an average of $1,147 every six months ($202/month) for full coverage — above the national average, with coastal and Lowcountry areas running notably higher. Auto-Owners is consistently the most affordable insurer in the state, averaging just $128/month for full coverage.

Average Cost of Car Insurance in South Carolina
South Carolina drivers pay more for car insurance than the national average — and the gap is meaningful. Full coverage across the state averages around $1,147 per six months, or approximately $2,294 annually. That places South Carolina notably above the national full coverage average of roughly $2,697 annually when adjusted for coverage-level comparisons, though the exact figure varies by data source and driver profile used in calculations.
The range within the state is equally significant. Drivers in mountain communities like Walhalla in Oconee County can see full coverage rates around $100/month, while drivers in coastal Ladson near Charleston can pay up to $176/month — a $76 monthly difference purely based on location. The Lowcountry's hurricane exposure, Charleston area traffic growth, and higher uninsured motorist rates along the coast all push premiums upward for those ZIP codes.
The national full coverage average sits around $2,697 per year. South Carolina's rates, while above average, are not the highest in the country — states like Michigan, Florida, and Louisiana consistently rank worse. Minimum coverage in SC averages around $444 per six months ($74/month), which covers only the legally required liability and uninsured motorist protection without comprehensive or collision.
| Coverage Type | SC Average (6-Month) | SC Average (Monthly) | National Average (Annual) |
|---|---|---|---|
| Full Coverage | $1,147 | $202 | $2,697 |
| Minimum Coverage | $444 | $74 | $820 |
Most South Carolina insurers quote rates on a six-month policy term. When you see monthly estimates, they're typically calculated by dividing the six-month premium — so $1,147 ÷ 6 = $191/month for full coverage at the state average. Always confirm whether a quote is for six months or a full year before comparing rates across companies. Paying your full six-month premium upfront rather than month-to-month can also save you an installment fee with most carriers.
Cheapest Car Insurance Companies in South Carolina
South Carolina has a competitive insurance market, and the price differences between companies can be dramatic. For the same driver profile, the gap between the cheapest and most expensive major insurer can exceed $3,000 per year. The table below shows average six-month premiums from leading SC insurers for both full coverage and minimum coverage, based on 2026 rate data from The Zebra.
| Company | Avg 6-Month (Min Coverage) | Avg Monthly (Min Coverage) | Avg 6-Month (Full Coverage) | Avg Monthly (Full Coverage) |
|---|---|---|---|---|
| USAA* | $236 | $39 | $793 | $132 |
| Auto-Owners | $327 | $54 | $767 | $128 |
| Progressive | $384 | $64 | $987 | $165 |
| Travelers | $405 | $68 | $931 | $155 |
| GEICO | $415 | $69 | $1,319 | $220 |
| Allstate | $418 | $70 | $1,022 | $170 |
| State Farm | $539 | $90 | $1,315 | $219 |
*USAA is available only to active military members, veterans, and their immediate families.
A few observations about this data. Auto-Owners wins on full coverage price for most drivers, while USAA edges ahead on minimum coverage for those who qualify. Travelers slots in as an underrated option — it offers competitive full coverage pricing and generally earns solid marks for claims handling in the Southeast. GEICO's full coverage rates are noticeably higher in South Carolina than many drivers expect based on its national advertising, partly due to the state's elevated catastrophic weather risk.
State Farm has the widest agent network in South Carolina, which matters if you prefer working with a local agent. Despite its higher average rates, State Farm's Drive Safe & Save telematics program can significantly reduce premiums for low-mileage or safe drivers, sometimes narrowing the gap with Auto-Owners or Travelers.
Auto-Owners consistently offers the lowest full coverage premiums in South Carolina for drivers who don't qualify for USAA. Beyond price, Auto-Owners earns consistently high ratings from J.D. Power for customer satisfaction and claims handling in the Southeast region. Their agent-only distribution model means you'll work with a dedicated local agent rather than an online portal — a genuine advantage when navigating claims after a hurricane or serious accident.
Car Insurance Rates by City in South Carolina
Where you live in South Carolina has a major impact on your car insurance premium. Coastal and metro areas pay significantly more than inland and rural communities. The table below shows average six-month full coverage premiums for major South Carolina cities, based on 2026 rate data. Cities with published city-specific guides are linked.
| City | Avg 6-Month Premium | Avg Monthly | Avg Annual |
|---|---|---|---|
| Mount Pleasant | $1,103 | $184 | $2,206 |
| Rock Hill | $1,133 | $189 | $2,266 |
| Columbia | $1,179 | $197 | $2,358 |
| Greenville | $1,198 | $200 | $2,396 |
| Spartanburg | $1,214 | $202 | $2,428 |
| Myrtle Beach | $1,224 | $204 | $2,448 |
| Sumter | $1,231 | $205 | $2,462 |
| Anderson | $1,235 | $206 | $2,470 |
| Florence | $1,240 | $207 | $2,480 |
| Charleston | $1,237 | $206 | $2,474 |
| North Charleston | $1,282 | $214 | $2,564 |
| Goose Creek | $1,295 | $216 | $2,590 |
| Hilton Head Island | $1,312 | $219 | $2,624 |
| Ladson | $1,056 | $176 | $2,112 |
North Charleston and Goose Creek consistently sit at the higher end of the state's rate spectrum. These communities sit adjacent to one of the busiest port operations on the East Coast — traffic from the Port of Charleston drives congestion, commercial vehicle density, and accident frequency in surrounding ZIP codes. Hilton Head Island sees higher rates partly due to the island's demographics and the concentration of high-value vehicles among retirees and second-home owners who benefit from year-round coverage.
Rock Hill's relatively moderate rates reflect its status as a bedroom community to Charlotte — while it's grown significantly, its accident frequency and theft rates remain lower than the larger metro core. Mount Pleasant, despite being one of the wealthiest suburbs in the state, benefits from well-maintained roads and lower crime rates that help offset its coastal location.
If you live in the Lowcountry or along the Grand Strand, your comprehensive coverage premium likely carries a coastal surcharge that drivers in Greenville or Spartanburg don't pay. South Carolina's coastline is directly in the path of Atlantic hurricane season activity. Comprehensive coverage pays for hurricane wind damage, flooding, and storm surge damage — all of which are genuine risks for vehicles parked within 50 miles of the coast. If you're debating whether to carry comprehensive, the answer is almost always yes for coastal SC residents.
South Carolina Minimum Car Insurance Requirements
South Carolina requires all registered vehicle owners to carry a minimum amount of liability insurance plus mandatory Uninsured Motorist coverage. These requirements have been stable for several years and were not changed for 2026. Understanding exactly what the minimums cover — and what they don't — is essential for making smart coverage decisions.
| Coverage Type | Minimum Required | What It Covers |
|---|---|---|
| Bodily Injury Liability (per person) | $25,000 | Medical costs for one person you injure |
| Bodily Injury Liability (per accident) | $50,000 | Total medical costs for all injured in one accident |
| Property Damage Liability | $25,000 | Damage to another person's vehicle or property |
| Uninsured Motorist BI (per person) | $25,000 | Your injuries when hit by an uninsured driver |
| Uninsured Motorist BI (per accident) | $50,000 | Total injuries for all in your car from an uninsured driver |
| Uninsured Motorist PD | $25,000 | Your vehicle damage from an uninsured driver |
The shorthand for South Carolina's minimums is 25/50/25: $25,000 per injured person, $50,000 maximum per accident for bodily injury, and $25,000 for property damage. The mandatory Uninsured Motorist (UM) coverage mirrors these limits exactly.
South Carolina's UM coverage comes in two forms: "Added On" and "Reduced" stacking options. With "added on" UM, you receive the full amount of your UM coverage on top of what the at-fault driver's liability insurance provides. With "reduced" UM, your coverage only pays the difference between the at-fault driver's limits and your own UM limits. "Added on" provides significantly better protection and is worth choosing if your insurer offers it.
South Carolina's 25/50/25 minimums were set years ago and don't reflect today's accident costs. A single serious injury accident in the Charleston metro area can easily produce medical bills exceeding $100,000 — four times the per-person limit. If the damages exceed your liability limits, you're personally responsible for the difference. Insurance professionals broadly recommend carrying at least 100/300/100 limits for drivers with any assets to protect, and even higher if you own a home or have significant savings.
Comprehensive and collision coverage are not required by South Carolina state law. However, if you have a car loan or lease, your lender will almost certainly require both. And given South Carolina's hurricane exposure and hail-prone weather in the Midlands and Upstate, carrying comprehensive is a smart choice for most drivers regardless of whether a lender requires it.
What Affects Car Insurance Rates in South Carolina
South Carolina's insurance rating environment has several state-specific factors that influence premiums beyond the universal variables like age, driving record, and credit score. Understanding what drives your rate helps you identify where you have the most leverage to lower it.
South Carolina is a traditional at-fault (tort) state. The driver who caused the accident is financially responsible for all resulting damages — medical bills, vehicle repairs, lost wages, and pain and suffering claims. There is no mandatory Personal Injury Protection (PIP) coverage in SC, and there's no system where each driver's own insurer pays for their own losses regardless of fault. If you're at fault, your liability insurance pays for the other party. If the other driver is at fault, you file against their liability policy — or against your own UM coverage if they're uninsured.
South Carolina's coastline runs from Myrtle Beach down through Hilton Head Island, passing through the heavily populated Charleston metro area. The state sits directly in the path of Atlantic hurricane season activity from June through November. Comprehensive coverage pays for wind, storm surge, and flood damage to your vehicle — and is essentially a non-negotiable for anyone living or parking within 50 miles of the coast. Insurers price this risk directly into premiums for coastal ZIP codes, which is why North Charleston and Goose Creek run $70–$90 per month more than inland areas like Greenville.
South Carolina has one of the higher uninsured driver rates in the Southeast, estimated at approximately 11% of all drivers on the road. Despite mandatory UM coverage requirements, enforcement gaps mean a meaningful percentage of vehicles you share the road with have no insurance at all. This drives up costs for insured drivers through higher UM coverage requirements and affects the overall claims environment. It's one reason South Carolina's rates sit above the national average despite not being the most densely populated state.
South Carolina permits insurers to use credit-based insurance scores as a rating factor. Drivers with poor credit can pay significantly more — sometimes 50%–80% more — than drivers with excellent credit for identical coverage. This isn't unique to SC, but it's more impactful here than in some other states. If your credit score has improved since you last shopped for insurance, it's worth getting new quotes rather than renewing with your current carrier, as your rate may not have been recalculated to reflect your better credit standing.
The Charleston and Columbia metro areas are among the fastest-growing in the Southeast. More residents, more vehicles, and more congestion on I-26, I-77, and I-526 translate directly into higher accident frequency and more claims. Urban ZIP codes in Charleston County and Richland County carry noticeably higher premiums than equivalent rural areas. The suburban expansion around Fort Mill and Rock Hill — bedroom communities to Charlotte, NC — has also pushed rates upward as these areas urbanize.
South Carolina's urban centers, particularly Columbia and the Charleston metro, see above-average vehicle theft rates compared to the national benchmark. Comprehensive coverage pays for theft, attempted theft, and vandalism — all risks that are meaningfully higher in urban SC than in rural areas. Vehicles on the NICB's high-theft list (certain pickup trucks, older Hondas, and full-size SUVs) carry higher comprehensive premiums in areas with elevated theft claims.
How to Save on Car Insurance in South Carolina
South Carolina's above-average rates make comparison shopping and discount optimization particularly valuable. Here are the most effective strategies for SC drivers looking to reduce their premiums without sacrificing coverage.
Compare Quotes from at Least 4–5 Insurers
In South Carolina, the spread between the cheapest and most expensive major insurer can exceed $3,000 per year for identical coverage on the same driver profile. Auto-Owners averages $767 per six months for full coverage; State Farm averages $1,315 for the same period. GEICO runs even higher at $1,319. Shopping broadly is the single most powerful lever you have. Don't assume your renewal rate is competitive — insurers routinely count on inertia to keep customers who could save significantly by switching.
Enroll in a Telematics or Usage-Based Program
Programs like Progressive's Snapshot, State Farm's Drive Safe & Save, and Allstate's Drivewise reward safe driving habits and low mileage with premium reductions of up to 30%. If you work from home, retired, or simply drive fewer than 10,000 miles per year, usage-based programs can generate meaningful savings on South Carolina's already-above-average rates. The Upstate and Midlands markets particularly benefit since these programs don't penalize you for the coastal risk factors baked into statewide averages.
Bundle Auto with Home or Renters Insurance
Multi-policy discounts in South Carolina typically reduce your auto premium by 10%–20%. Auto-Owners, State Farm, Travelers, and Allstate all offer competitive bundling discounts in SC. Given South Carolina's strong homeownership rates and the prevalence of vacation and second homes along the coast, bundling home and auto with the same carrier is often the most direct path to a significant premium reduction.
Raise Your Deductible on Older Vehicles
If your vehicle is more than 8–10 years old and worth less than $6,000, the math on carrying comprehensive and collision coverage at a $500 deductible often doesn't work in your favor. Raising your deductible from $500 to $1,000 can cut your full coverage premium by 15%–25%. For vehicles worth under $4,000, dropping collision entirely may make financial sense — though keep comprehensive if you're in a coastal area where storm and flood risk is real.
Improve Your Credit Score Before Shopping
South Carolina insurers can and do use credit-based insurance scores as a rating factor. Drivers who have recently improved their credit — paid down debt, resolved collection accounts, or reduced their credit utilization ratio — often find that their insurance rates haven't caught up with their improved financial profile. Before your next renewal, check your credit report for errors, then shop for new quotes. A move from poor to average credit can cut your premium by 30%–50% with many carriers.
South Carolina doesn't have a state-mandated safe driver program like North Carolina's SDIP, but most major insurers offer their own safe driver discounts. Progressive, GEICO, and State Farm all provide discounts of 10%–26% for drivers who go three or more years without an accident or moving violation. If you've had a clean record for several years, explicitly ask each insurer about their safe driver discount and whether it's already being applied to your quote — it's sometimes not automatically included in initial estimates.
South Carolina Car Insurance Laws and Regulations
South Carolina's auto insurance framework is governed by the SC Department of Insurance (SCDOI) and enforced through the SC Department of Motor Vehicles. Here's what every driver in the state needs to understand about their legal obligations.
At-Fault Insurance System
South Carolina is an at-fault (tort) state. When an accident occurs, the driver found to be at fault is financially responsible for all damages — bodily injury, property damage, and related costs — through their liability insurance. The injured party files a claim against the at-fault driver's liability policy rather than their own insurance first.
This differs from "no-fault" states like Florida or Michigan, where each driver's own insurance pays for their own injuries regardless of who caused the accident. In South Carolina, if the other driver is at fault, you seek compensation from their insurer. If you are at fault, your liability coverage pays for the other party's losses. This system places a premium on carrying adequate liability limits — the minimum 25/50/25 is often insufficient for serious accidents.
Mandatory Uninsured Motorist Coverage
South Carolina law requires all drivers to carry Uninsured Motorist coverage equal to their liability limits (minimum 25/50/25). This coverage protects you when the at-fault driver either has no insurance or has insufficient coverage to pay for your damages.
SC also requires Underinsured Motorist (UIM) coverage, which pays the difference when the at-fault driver's liability limits are lower than your actual damages. Given that a significant percentage of SC drivers carry only the state minimum 25/50/25 — limits that can be exhausted by a single hospitalization — UIM coverage is a meaningful financial protection.
South Carolina offers "added on" stacking for UM/UIM coverage, which provides the full amount of your UM limits on top of whatever the at-fault driver's insurance pays. This is a significantly better option than "reduced" (non-stacked) coverage and is worth selecting when your insurer offers the choice.
Proof of Insurance Requirements
South Carolina drivers must be able to provide proof of insurance when requested by law enforcement. The state operates an electronic insurance verification system that allows the SC DMV and law enforcement to check insurance status in real time. Electronic proof of insurance on a smartphone is accepted by SC law enforcement — you are not required to carry a physical insurance card if you have a digital copy accessible.
Penalties for Driving Without Insurance
South Carolina takes uninsured driving seriously. The penalties for operating a vehicle without required insurance include:
| Violation | Penalty |
|---|---|
| First offense — driving uninsured | $100–$200 fine + license and registration suspension |
| Subsequent offenses | $200–$400 fine + suspension + possible jail time |
| Registration reinstatement fee | $200 (first offense) / $400 (subsequent) |
| License reinstatement fee | $100 |
| Driving during suspension | Criminal charge, additional fines, possible imprisonment |
Beyond the fines, being caught without insurance in South Carolina results in your vehicle registration and driver's license being suspended. Reinstatement requires proof of new insurance coverage and payment of reinstatement fees. If you're involved in an accident while uninsured, you are personally liable for all damages — which can mean lawsuits, judgments, and wage garnishment for years after the incident.
SR-22 Requirements in South Carolina
South Carolina uses the SR-22 certificate system to monitor high-risk drivers who have had their license suspended or revoked due to serious violations. An SR-22 is a form filed by your insurer with the SC DMV, certifying that you carry the state's minimum required insurance. It's not a separate type of insurance — it's a certificate attached to your existing policy.
You may be required to file an SR-22 in South Carolina after a DUI/DWI conviction, reckless driving conviction, accumulation of excessive points on your license, driving without insurance, or being involved in an at-fault accident while uninsured. SR-22 requirements in SC typically last three years from the date of the offense. Not all insurers file SR-22s — Progressive, State Farm, and several regional carriers do offer SR-22 filings for SC drivers who need them.
New Resident Insurance Requirements
If you move to South Carolina from another state, you must obtain SC auto insurance and register your vehicle within 90 days of becoming a resident. Your out-of-state policy may be temporarily valid during the grace period, but you'll need to update your registration and insurance to meet SC requirements. New residents from states with different minimum coverage requirements — particularly those moving from states with PIP/no-fault systems — should review their coverage with a local agent to ensure their policy complies with SC law.
Frequently Asked Questions About South Carolina Car Insurance
Auto-Owners offers the cheapest full coverage car insurance in South Carolina for most drivers, averaging $767 per six months ($128/month). USAA is cheaper at $793 per six months ($132/month) for full coverage, but is only available to active military members, veterans, and their immediate families. For minimum coverage, USAA leads at $236 per six months ($39/month), followed by Auto-Owners at $327 per six months ($54/month). Your individual rate will vary based on your ZIP code, driving record, age, credit score, and vehicle — always compare at least four or five quotes before choosing a carrier.
The average cost of full coverage car insurance in South Carolina is approximately $1,147 per six months, or roughly $2,294 per year ($202/month). Minimum coverage averages around $444 per six months ($74/month or $888 annually). These are 2026 averages based on a standard driver profile — your actual rate will depend on your specific ZIP code, driving history, age, and credit score. Coastal areas like North Charleston, Goose Creek, and Hilton Head Island see rates significantly above the state average, while inland communities like Walhalla and Rock Hill run well below it.
South Carolina is an at-fault (tort) state. The driver who causes an accident is responsible for paying the other party's damages through their liability insurance. There is no mandatory Personal Injury Protection (PIP) requirement in SC, and there is no system where each driver's own insurer automatically pays their own losses regardless of fault. If another driver causes an accident that injures you or damages your vehicle, you file a claim against that driver's liability insurance — or against your own Uninsured Motorist coverage if the at-fault driver has no insurance.
South Carolina requires all drivers to carry: $25,000 bodily injury liability per person, $50,000 per accident, and $25,000 property damage liability (written as 25/50/25). You must also carry mandatory Uninsured Motorist coverage at matching limits — $25,000/$50,000 BI and $25,000 property damage. These minimums have not changed for 2026. Comprehensive and collision are not required by state law but are typically required by lenders if you finance or lease your vehicle. Given today's medical and repair costs, most insurance professionals recommend carrying at least 100/300/100 limits.
South Carolina uses the SR-22 filing system for high-risk drivers whose licenses have been suspended or revoked. An SR-22 is a certificate filed by your insurer with the SC DMV, certifying that you carry the state minimum required insurance. You may need an SR-22 after a DUI/DWI conviction, driving without insurance, reckless driving, or excessive license points. SR-22 requirements typically last three years in South Carolina. Not all insurers offer SR-22 filings, so if you need one, confirm the carrier can file it before purchasing a policy. Progressive and State Farm are among the major carriers that do file SR-22s for SC drivers.
Among major South Carolina cities, Mount Pleasant tends to have the lowest average rates, followed by Rock Hill. Mount Pleasant averages around $1,103 per six months ($184/month) for full coverage, while Rock Hill averages $1,133 per six months ($189/month). Smaller inland towns like Walhalla in Oconee County can run even lower — around $100/month for full coverage — due to low traffic density and minimal weather risk. North Charleston and Goose Creek are consistently among the most expensive cities in SC, reflecting their proximity to the port, higher traffic density, and coastal weather exposure.
South Carolina requires all insured drivers to carry Uninsured Motorist (UM) coverage equal to their liability limits as a direct protection against drivers who have no insurance. Despite this requirement, approximately 11% of SC drivers are estimated to be uninsured. If an uninsured driver hits you, your UM coverage pays for your bodily injuries and vehicle damage up to your policy limits. SC's "added on" stacking option for UM is particularly valuable — it provides your full UM limit on top of whatever the at-fault driver's (insufficient) coverage pays, rather than just paying the difference. Always confirm with your insurer whether your UM coverage is "added on" or "reduced."
