What Commercial Auto Insurance Is Required in South Carolina?

Under S.C. Code § 38-77-140, South Carolina mandates commercial auto insurance requirements at 25/50/25 split liability limits, along with uninsured motorist (UM) coverage on every policy:

$25,000 for bodily injury or death of one person per accident (S.C. Code § 38-77-140)
$50,000 for bodily injury or death of two or more people per accident
$25,000 for property damage per accident

Most businesses running standard vehicles at or under 10,000 lbs GVWR fall under these baseline limits. One common mistake is assuming a personal auto policy covers business use: it doesn't, and South Carolina is one of roughly 20 states that also require UM coverage on commercial policies, a requirement many business owners don't realize exists until a claim is denied. For-hire carriers regulated through the South Carolina Public Service Commission, passenger transport operations and any business moving hazardous materials must carry substantially higher coverage.

South Carolina's Public Service Commission requires for-hire carriers at 10,001 lbs GVWR or above to carry $750,000 CSL under S.C. Code Reg. 38-414. Vehicles that travel interstate or carry cargo as part of an interstate shipment fall under federal FMCSA rules instead, even if the truck never leaves South Carolina. Businesses that own their vehicles outright and don't haul for hire stay at 25/50/25 regardless of weight.
Under 10,001 lbs
25/50/25 state minimum
Standard business vehicles
10,001+ lbs
$750,000 CSL
For-hire intrastate carriers (CDL required at 26,001+ lbs)
South Carolina's coverage thresholds are tied to your GVWR (Gross Vehicle Weight Rating), the maximum safe operating weight including fuel, driver, passengers and cargo, not what your truck weighs on a scale. A Ford F-350 with a 10,200 lb GVWR crosses the $750,000 CSL threshold even when it's empty, so check these locations for your rating:
- On your vehicle: Check the driver-side door jamb, door edge or pillar for a South Carolina or federal compliance label. It may also be listed as GAWR (axle ratings).
- Owner's manual: Section names vary but often appear under specifications, vehicle identification, weight information, towing/trailering and technical data.
- Manufacturer website: Search by your vehicle's year, make and model for GVWR specs on the automaker's site.

Carrying passengers for hire in South Carolina triggers coverage between $250,000 CSL and $5 million, depending on seating capacity. The sharpest jump occurs at 16 seats, where federal FMCSA rules take over. These tiers don't apply to businesses that only move their own employees in company vehicles: employee transport in a company van stays at the 25/50/25 baseline as long as you aren't charging fares.


8 or fewer	$250,000 CSL	Intrastate for-hire (PSC regulated)
9–15	$750,000 CSL	Intrastate for-hire (PSC regulated)
16+	$5,000,000 CSL	Federal FMCSA requirement

South Carolina's PSC counts seating capacity based on the vehicle's manufactured rating, not how many passengers you typically carry, so a 15-seat van triggers the $750,000 CSL tier even if you only fill eight seats per trip. Operators who add or remove seats after purchase should update their PSC filings to avoid being insured at the wrong tier.

Rideshare and TNC drivers in South Carolina operate under a two-phase insurance structure created by S.C. Code §§ 58-23-1610 et seq., signed into law in 2015. The key point for drivers and businesses: coverage applies the moment the app is turned on at $50,000/$150,000/$25,000, not when a rider is actually in the car.
App on, waiting for request
TNC driver or TNC
$50,000/$150,000/$25,000 liability + UM
Ride accepted through drop-off
TNC driver or TNC
$1,000,000 CSL + UM
S.C. Code § 58-23-1625 allows personal auto insurers in South Carolina to deny every type of coverage while a driver is logged into a rideshare platform, creating a real exposure window where the driver bears the full financial weight of a claim if the TNC's $1,000,000 CSL policy hasn't attached yet. These TNC requirements don't apply to taxi companies, limousine services or charter buses, which fall under separate PSC carrier rules.

Federal FMCSA rules require $1,000,000 to $5,000,000 CSL for hazmat cargo insurance regardless of whether your truck stays inside South Carolina's borders. For everything else, the state ties coverage to vehicle weight rather than what's in the truck. For-hire carriers above 10,001 lbs GVWR need $750,000 CSL under S.C. Code Reg. 38-414.


High-risk hazmat	$5,000,000 CSL	Tanks over 3,500 gallons, Class A or B explosives, poison gas, liquefied compressed gas and other hazardous substances per 49 CFR Part 171
Standard hazmat	$1,000,000 CSL	Regulated materials per federal DOT rules
Oil transport	$1,000,000 CSL	Any federal quantity
Non-hazmat (10,001+ lbs GVWR)	$750,000 CSL	General freight, equipment and non-regulated cargo
Non-hazmat (under 10,001 lbs GVWR)	25/50/25 state minimum	Light-duty commercial cargo

Vehicle size doesn't matter for high-risk hazmat under federal rules: a South Carolina cargo van hauling regulated quantities of Class A explosives carries the same $5,000,000 CSL requirement as a full tractor-trailer at 80,000 lbs GVWR. Non-hazmat cargo doesn't trigger the $750,000 CSL tier unless the vehicle's GVWR hits 10,001 lbs and it operates as a for-hire carrier.

WHEN DOES FEDERAL LAW APPLY OVER RHODE ISLAND LAW?

Federal FMCSA insurance rules apply to any South Carolina vehicle with a GVWR of 10,001 lbs or more in interstate commerce, and your truck doesn't have to physically leave the state: if the freight originated in another state, federal minimums can govern even on a local run. Confirm your classification with the South Carolina Department of Motor Vehicles before assuming state rules apply. You can also review FMCSA insurance filing requirements, though businesses operating entirely within South Carolina's borders with vehicles under 10,001 lbs GVWR stay under state-only 25/50/25 minimums.

South Carolina Commercial Auto Insurance Requirement Exemptions

Agriculture and forestry run deep in South Carolina's economy, and S.C. Code § 58-23-50 reflects that by exempting a range of farm, forest and specialty transport operations from PSC certification and its higher coverage thresholds. These carve-outs don't remove the baseline: every vehicle on a South Carolina public road still needs at least 25/50/25 liability plus UM. Confirm your status through the South Carolina DMV or the Office of Regulatory Staff before assuming lower requirements apply.


Farmers or dairymen hauling farm or dairy products	25/50/25 state minimum liability + UM
Livestock and poultry feed transporters	25/50/25 state minimum liability + UM
Perishable farm product haulers (farm to first market)	25/50/25 state minimum liability + UM
Lumber haulers (forest to shipping points in South Carolina)	25/50/25 state minimum liability + UM
Log, chip or wood residue haulers (under DPS Transport Police rules)	25/50/25 state minimum liability + UM, plus DPS Transport Police compliance
Church or school vehicles (transporting to/from services or school)	25/50/25 state minimum liability + UM
US mail carriers on star routes	Federal postal service requirements
Vehicles used for personal (non-business) purposes	Personal auto insurance rules
Tow trucks responding to accident scenes	25/50/25 state minimum liability + UM (PSC rules don't apply for emergency response)

South Carolina courts interpret these exemptions narrowly: in 2009, the South Carolina Supreme Court ruled that a tree hauler running daily commercial loads didn't qualify as a lumber hauler because his operation was for-profit transport, not farm-to-market delivery. Businesses in Columbia, Charleston, Greenville and other metro areas should confirm their classification with the South Carolina Office of Regulatory Staff before relying on a lower coverage tier.

South Carolina Commercial Auto Insurance Alternatives

Three options exist in South Carolina for meeting financial responsibility requirements without a standard commercial auto policy, all governed by S.C. Code §§ 56-9-540 through 56-9-580. These alternatives don't reduce the amount of coverage you need: they just change how you fund it. Most small fleets with fewer than 25 vehicles won't qualify for self-insurance and are better served by a standard policy.

Surety bond: A surety bond filed with the South Carolina DMV under S.C. Code § 56-9-570 satisfies financial responsibility if it meets or exceeds the 25/50/25 state minimums. The bond must come from a surety company licensed in South Carolina, and a lapsed or canceled bond triggers the same penalties as having no insurance at all. For-hire carriers also need to meet separate filing obligations under S.C. Code § 58-23-910.
Self-insurance: Companies with more than 25 motor vehicles registered in their name may apply for a self-insurance certificate under S.C. Code § 56-9-60. The bar is high: you need either a net worth of at least $20 million or a segregated claims deposit of $3,000 per vehicle (80% in cash or an irrevocable letter of credit, 20% in appraised South Carolina real estate). A CPA-audited financial statement showing positive net worth is required with every application.
Cash or securities deposit: S.C. Code § 56-9-580 allows you to deposit cash or securities with the South Carolina DMV in an amount that covers the state's financial responsibility minimums. The DMV holds the deposit to satisfy any judgments from future vehicle accidents, and the full amount must remain on deposit for as long as vehicles stay registered.

South Carolina Special Commercial Auto Insurance Coverage Circumstances

Beyond the standard 25/50/25 requirements, three situations in South Carolina can create coverage gaps or trigger extra obligations that catch business owners off guard.

Leased commercial vehicles

If you lease commercial vehicles in South Carolina, the lessor typically either adds you to its policy or requires you to carry your own coverage at the state minimum or higher. The problem is that South Carolina's $25,000 property damage floor won't come close to covering the remaining balance on a totaled leased vehicle. Gap coverage bridges that shortfall, and most leasing companies won't finalize a contract without it.

Farm vehicles on public highways

The exemptions under § 58-23-50 protect farm-to-market transport, but they're narrow. Driving a farm truck from a field to a local produce buyer is covered; using that same truck to move goods between two commercial warehouses isn't. Anytime your agricultural vehicles operate beyond traditional farm routes, treat them as standard commercial vehicles and carry at least 25/50/25 plus UM.

Coastal storm and flood exposure

From Myrtle Beach through Charleston down to Hilton Head, South Carolina's 187-mile coastline exposes commercial fleets to hurricane and flood damage that standard liability policies won't cover. Comprehensive coverage with flood protection isn't required under S.C. Code § 38-77-140, but it's the only way to cover your own vehicles from storm losses in these high-risk counties.

South Carolina Commercial Auto Insurance Enforcement and Penalties

South Carolina monitors coverage status electronically through its Motorist Insurance Database under S.C. Code § 56-10-610, which flags lapses as soon as an insurer reports a cancellation. Officers also verify insurance during routine traffic stops, and the South Carolina DMV retains authority to demand proof of coverage from any registered vehicle owner.


First (uninsured vehicle)	$100–$200 or 30 days jail	Immediate until proof of coverage	$200 fee + SR-22 filing
Second (within 5 years)	$200 + 30 days jail	Immediate until proof of coverage	$200 fee + SR-22 filing
Third or more (within 5 years)	45 days–6 months jail	Immediate until proof of coverage	$200 fee + SR-22 filing
Per-day surcharge (no coverage)	$5 per day, up to $200	N/A	N/A

After any uninsured vehicle conviction in South Carolina, your insurer must file an SR-22 that stays on record for three years under § 56-10-520, and even a one-day coverage lapse triggers a $5 per day surcharge through the state's electronic database now that the 2023 repeal of the $550 to $600 uninsured motorist fee (Act 51, effective July 2024) requires every registered vehicle to carry active coverage. Federally regulated carriers are subject to separate FMCSA enforcement on top of these state penalties.

How To Verify Your Business Meets South Carolina Commercial Auto Insurance Requirements

Walk through these seven steps for each vehicle in your fleet to confirm you're carrying the correct South Carolina 25/50/25 minimum or the higher PSC, federal or for-hire threshold that applies.

1
Check whether a carrier exemption applies
S.C. Code § 58-23-50 carves out farm haulers, lumber transporters, church buses and several other categories from PSC carrier rules. Before relying on one of these exemptions, confirm it with the South Carolina Office of Regulatory Staff because courts have interpreted them narrowly.
2
Define each vehicle's primary use
Pin down whether a vehicle hauls passengers, moves freight, operates locally or crosses state lines in South Carolina. A passenger van at eight seats or fewer and a 26,001 lb box truck hauling freight across state lines fall into completely different coverage tiers.
3
Look up the vehicle's weight rating
Locate the GVWR on the driver-side door label. At 10,001 lbs or above, for-hire carriers in South Carolina owe a $750,000 CSL minimum under South Carolina Reg. 38-414, and federal rules may layer on top.
4
Sort out state versus federal jurisdiction
Local-only operations follow South Carolina's 25/50/25 minimums or the PSC carrier thresholds. Any interstate freight or passenger activity can shift your obligation to federal FMCSA thresholds, which start at $750,000 CSL.
5
Match your liability limits to the applicable requirement
A standard South Carolina business vehicle needs 25/50/25 liability plus UM. For-hire carriers, passenger operators and federally regulated fleets owe more, often $750,000 or above.
6
Audit your policy against actual vehicle use
Confirm that every vehicle is classified correctly on the South Carolina policy, all drivers are listed and the coverage matches what the vehicle actually does. A truck coded as "personal use" when it's running commercial loads under South Carolina Reg. 38-414 can result in a denied claim.
7
Look for South Carolina-specific gaps
Coastal flood exposure, TNC coverage windows under S.C. Code §§ 58-23-1610 et seq. and farm-vehicle route limits are the three most common gap areas in this state. Address each one that applies to your fleet.

South Carolina Commercial Auto Insurance Requirements: Bottom Line

What your South Carolina business owes in commercial auto coverage, whether it's the 25/50/25 baseline, $750,000 CSL for a for-hire carrier or $5 million for a large passenger operation, comes down to vehicle use, weight class and whether any part of your operation touches interstate commerce. The right move from here is matching each vehicle in your fleet to the correct requirement tier and confirming your policy language reflects it.

South Carolina Commercial Auto Insurance Requirements: Next Steps

Knowing the legal minimums for South Carolina commercial auto insurance is step one, whether that's 25/50/25 for a standard vehicle or $750,000 CSL for a for-hire carrier. Step two is deciding whether those floors are actually enough for what your business stands to lose in a serious claim, and that depends on your vehicles, routes and contracts.

If your goal is just legal compliance

Verify that each vehicle's liability limits hit the South Carolina 25/50/25 minimum or the federal threshold that applies. Double-check that your insurer has classified every vehicle correctly. An inaccurate use code can void coverage when you get commercial auto insurance coverage.

If your vehicles are valuable or highly visible

At $25,000, South Carolina's property damage minimum barely covers a fender bender in downtown Charleston, let alone a multi-vehicle pileup on I-26. Branded vehicles, tool-loaded trucks and any fleet visible to the public should carry property damage and liability limits well above the state floor.

If you transport passengers

PSC-regulated carriers already carry minimums between $250,000 and $5 million depending on seating capacity. Even so, a single passenger injury claim in a busy corridor like the I-85 stretch through Greenville can exceed those floors fast. Build in a buffer.

If you haul goods or equipment

The $750,000 CSL floor for for-hire carriers at 10,001+ lbs GVWR may fall short when heavy loads or high-value cargo are involved. A total loss on a load worth $500,000 or more can blow through that limit before property damage even enters the equation.

If your business signs contracts

Most commercial contracts in South Carolina set insurance minimums above the state's legal thresholds. Read every agreement before signing. A $1 million CSL requirement in a client contract overrides the $25,000 PD minimum the state sets, and showing up without it can cost you the job.
