Minimum Insurance Requirements in South Carolina
All interstate carriers operating in South Carolina must meet the federal FMCSA minimum insurance requirements set in 49 CFR §387. Intrastate-only operations may follow South Carolina's own thresholds, which in most cases mirror or exceed the federal baseline.
| Coverage Type | Federal Minimum | Applies To |
|---|---|---|
| Primary Liability (general freight) | $750,000 | Non-hazardous freight over 10,001 lbs GVW |
| Primary Liability (oil) | $1,000,000 | Petroleum & petroleum products |
| Primary Liability (hazmat) | $5,000,000 | Hazardous materials & pollutants |
| Motor Truck Cargo | $5,000 per vehicle / $10,000 per occurrence* | Household goods movers (federally required) |
*Federal cargo minimum applies only to household-goods movers. Most general-freight shippers contractually require $100K cargo coverage.
Federal vs. South Carolina Requirements
South Carolina hosts the Port of Charleston (one of the top 10 US container ports by volume) and the BMW and Volvo manufacturing plants in Spartanburg and Ridgeville generate steady inbound and outbound freight. I-95 runs the length of the state and I-26 connects Charleston to the upstate. South Carolina defers to FMCSA federal minimums for interstate and offers some of the more competitive Southeast premium baselines for clean-record carriers.
If you're filing for new authority, FMCSA will not activate your operating authority until your insurance carrier files the BMC-91 (liability) and, where applicable, the BMC-34 (cargo) forms. Trucker Path Insurance handles these filings as part of binding any new-authority policy in South Carolina.
Average Cost of Trucking Insurance in South Carolina
For an owner-operator with a clean driving record and seasoned authority, typical annual commercial trucking insurance premiums in South Carolina fall in the range of $8,500 – $15,500. Actual rates depend on cargo type, radius of operation, equipment age, driving record, and authority age.
New-MC carriers in their first 12 months typically pay 25-50% above seasoned rates, then see a substantial reduction once they show 12 months of clean loss runs.

How to Get Trucking Insurance in South Carolina
- Have your USDOT number and MC authority ready. If you haven't filed yet, FMCSA registration must be in progress before binding.
- Decide on cargo and radius. Premium pricing varies by cargo class (general freight vs. reefer vs. flatbed vs. hazmat) and how far from your domicile you operate.
- Choose the right coverage stack. At minimum: primary liability + cargo. Most carriers also need physical damage and motor-truck-cargo coverage at $100K+. See our full coverages page for details.
- Get quotes from multiple carriers. Trucker Path Insurance shops across 10+ commercial carriers in South Carolina to find the best rate for your specific operation.
- Bind and file. Once you accept a quote, we file BMC-91 (and BMC-34 if applicable) electronically with FMCSA — typically within 24 hours.
South Carolina Trucking Insurance FAQ
What's the typical cost of commercial truck insurance in South Carolina?
A seasoned owner-operator with clean MVR running general freight from South Carolina pays approximately $8,500-$13,500 annually for primary liability plus motor truck cargo. SC's premium baselines run about 5-10% below the national average thanks to a less litigious accident environment than neighboring Florida or Georgia metros.
Do I need special coverage for hauling out of the Port of Charleston?
Yes. Port of Charleston intermodal access requires UIIA (Uniform Intermodal Interchange Agreement) compliance, which mandates $1M primary liability + $100K motor truck cargo — above FMCSA's $750K baseline. Trailer interchange coverage is also required when pulling steamship-line containers. We handle UIIA-spec policies for Charleston-based carriers.
How does BMW/Volvo manufacturing freight affect insurance underwriting?
Tier-1 automotive contracts (BMW Plant Spartanburg, Volvo Ridgeville, the upcoming Scout EV plant) require contract-specific minimums — typically $1M-$2M primary liability, $250K motor truck cargo with manufacturer-spec endorsements, and clean drug-testing compliance. Carriers running these lanes are underwritten more strictly but often earn rate discounts for the steady, predictable freight.
