South Carolina plays a vital role in the Southeast’s transportation network. From the booming Port of Charleston—one of the fastest-growing drayage markets on the East Coast—to the busy I-26 and I-95 freight corridors, trucking businesses here keep goods moving every day. With high traffic volumes, major shipping hubs, and state and federal regulations to navigate, the risks are real.
That’s where the right insurance coverage comes in.
Why Trucking Insurance Matters in South Carolina
Running a trucking business isn’t just about moving freight—it’s about managing risk. Accidents, cargo damage, equipment breakdowns, and liability claims can all impact your business quickly.
Commercial trucking insurance helps protect:
- Your trucks and trailers
- Your cargo
- Your drivers
- Your business from costly lawsuits
Without the right coverage, one claim could disrupt your entire operation.
South Carolina’s Insurance Requirements
South Carolina’s minimum insurance requirements are set by both the SC Public Service Commission (PSC) and the Federal Motor Carrier Safety Administration (FMCSA). The amount of coverage required depends on your cargo type, truck weight, and whether you operate intrastate or across state lines.
Current minimum liability requirements include:
- General freight (trucks over 10,001 lbs): at least $750,000 in liability coverage
- Vans and Sprinters / lighter non-hazardous freight: minimum $300,000 in liability coverage
- Oil transport: at least $1,000,000 in liability coverage
- Hazardous materials: up to $5,000,000 in liability coverage depending on material type
Intrastate carriers operating trucks over 10,000 lbs must obtain a South Carolina Intrastate DOT number through the PSC. Interstate operators must also comply with FMCSA requirements and obtain a USDOT number. Both SC and the USDOT require specific insurance filings to be submitted by your agent before you can legally operate. Note that many brokers and shippers now require a minimum of $1,000,000 in liability coverage on all 18-wheelers, even where the regulatory floor is lower.
Key Coverages Every Trucking Business Should Consider
Meeting state minimums is just the starting point. Most trucking businesses need additional protection to stay fully covered.
Auto Liability Insurance
Covers bodily injury and property damage if your truck is at fault in an accident. Required by law for all South Carolina motor carriers.
Physical Damage Coverage
Helps repair or replace your truck after collisions, theft, fire, or weather-related damage.
Motor Truck Cargo Insurance
Protects the freight you’re hauling from loss, theft, or damage—essential whether you’re moving goods through Charleston’s port, across I-95, or along rural SC routes.
Umbrella or Excess Liability
Provides additional coverage above your primary policy—especially important with rising claim costs and broker requirements pushing limits to $1,000,000 or more.
Workers’ Compensation
Required if you have employees, covering injuries and lost wages. Owner-operators may consider Occupational Accident coverage as an alternative.
Non-Trucking Liability / Bobtail Insurance
Covers your truck when it’s being operated outside of dispatch—important for leased owner-operators running under a motor carrier’s authority.
What Impacts Your Trucking Insurance Cost?
Insurance premiums in South Carolina can vary based on:
- Type of cargo hauled
- Driving radius (local vs. long haul)
- Driver experience and records
- Equipment value
- Claims history
- Proximity to major shipping corridors like I-26, I-95, and the Port of Charleston
Average commercial truck insurance in South Carolina costs around $14,727 annually, with most premiums ranging from $12,791 to $16,956 per truck. SC rates are generally moderate for the Southeast, though costs can vary significantly near major freight corridors. Safer operations and strong risk management practices can help keep premiums under control.
Stay Compliant and Protected
South Carolina’s dual state/federal regulatory structure means it’s critical to have a policy that meets the correct limits for your specific cargo and operating area. Even if you already have coverage, your limits may not match current PSC requirements or what brokers and shippers now demand.
A quick policy review can help identify:
- Coverage gaps
- Outdated limits
- Opportunities to bundle or improve protection
