South Carolina Commercial Truck Insurance Quotes

Last reviewed August 2026 by the Trucking Insurance Services team.

South Carolina is a good state to build a trucking company in. The freight here is unusually varied for a state this size. Finished vehicles roll out of the Upstate by the thousand, containers move through Charleston, flatbeds run building materials and machinery, and produce heads north on I 95. There is steady work here, and room to grow into it.

South Carolina truck insurance should be the straightforward part of building that business, and with us it is. We write commercial trucking and nothing else, we put carriers up against each other for your policy instead of handing you one number, and most quotes go out the same day.

Whatever you run, we quote it. Car haulers, over the road semis, flatbeds, refrigerated, box trucks, hotshots, lowboys, dump trucks and container work out of the port, from the Upstate down to the coast.

What you get from us in South Carolina Your quote: same day in most cases, shopped across multiple carriers, not one. Your cost: real South Carolina numbers by operation, in the table below. Your filings: the BMC 91X handled on your MC number, so your authority goes active. Your car haul or container work: specialist placements that many agencies pass on. We do both, constantly.

Starting a new trucking authority in South Carolina

South Carolina is a strong state to start in, and the reason is competition. A lot of markets want business here, which means a new authority gets shopped rather than handed a single take it or leave it number. We quote new ventures across multiple carriers the same day.

What you plan to haul shapes which of those markets look at you first. A car hauler, a flatbed running out of the Upstate and a container chassis working the port are three different risks, and they are not underwritten by the same people. Tell us what you are building toward and we will tell you which markets fit before you spend money on authority.

We also walk you through what you are actually looking at before you sign: the limits your brokers will demand, what your down payment does to your monthly, and what changes at your first renewal once you have twelve months of your own record behind you. If you are still working through authority itself, start with how to get your MC and DOT numbers and new venture truck insurance.

Why South Carolina truckers put us to work

Our founder, Eva Clair Bowles, drove a truck before she sold insurance. She owned the tractor and the trailer and ran the loads, and she opened this agency in 2007 to be the agency she wished she had had when she started. That is still how we hire and how we think.

• Carriers compete for you. South Carolina is a busy market and we make the carriers that want it bid against each other.
• We place car haulers. High value freight on an open trailer is its own underwriting conversation, and it is one we have constantly.
• We place container work. Pulling boxes out of Charleston means satisfying an agreement, not just buying a policy. We set it up so it passes the first time.
• Certificates in minutes. A late certificate costs you a load. Ours do not run on a ticket queue.
• Filings are routine here. The BMC 91X goes out as soon as you bind.

What South Carolina truck insurance costs

These are the ranges we place in South Carolina for a single truck. Where you land inside a range depends far more on your driving record, your radius and what you haul than on the truck itself.

Ranges reflect policies we write. Car hauling and container work sit near the top because both carry higher cargo limits than general freight, not because the truck is riskier. Physical damage is priced as a percentage of what your equipment is worth, generally 3% to 12% of the truck and trailer value. For what cargo limits cost on their own, see our cargo insurance cost guide.

What influences your South Carolina rate

Most of what moves your premium is inside your control, and knowing which levers matter is half of shopping it well.

• What you haul, and what it is worth. The biggest single lever in South Carolina. A load of new vehicles and a load of lumber are not the same cargo conversation even behind the same tractor.
• Driver records and CDL experience. The fastest lever you have, and the first thing an underwriter looks at.
• DOT safety scores and inspection history. Underwriters see inspections within days now, not months, and brake and tire violations move renewals.
• Time under authority. Year one prices differently from year three. It is temporary, and it opens doors that were shut at the start.
• Radius. A dedicated run from the Upstate to Charleston and a truck going wherever the load board sends it are different risks on paper.
• Equipment value and deductibles. Physical damage follows the value of the truck, and the deductible you pick is a real lever on the monthly.

What South Carolina requires you to carry

If you run interstate

You are under FMCSA rules and your insurance company files the BMC 91X against your MC number. That is the filing that turns your authority active, and in South Carolina it is the only one most operators ever deal with. The federal floor and what your brokers will actually accept are two different numbers, and that gap is what catches new authorities out.

If you run South Carolina only

Intrastate carriers register with the South Carolina Public Service Commission and meet the insurance requirements that come with it. In practice the number that decides whether you get loaded is not the state minimum, it is what your shippers and brokers want to see on the certificate, and that is almost always higher. We build to whichever bar is higher and handle the paperwork either way.

Whichever way you run, you will also need your IRP plate through the SCDMV, an IFTA account through the South Carolina Department of Revenue, and a UCR registration if you cross state lines. Tell us how you actually run and we will tell you exactly what your operation needs.

Built for how South Carolina actually trucks

South Carolina packs an unusual amount of freight variety into a small state. Automotive manufacturing in the Upstate, a deepwater container port at Charleston, and everything that supplies and moves around both. We write all of it.

• Car hauling and auto transport. The state’s signature operation, and the one below. See auto hauler insurance.
• Over the road and dry van. The backbone, running I 95, I 26 and I 85. See commercial truck insurance.
• Flatbed and lowboy. Machinery, building materials and equipment moves, where securement drives the cargo conversation.
• Refrigerated. Produce and temperature controlled freight, where the breakdown endorsement matters as much as the limit. See reefer truck insurance.
• Intermodal and container drayage. Pulling boxes out of Charleston, which normally means a UIIA agreement. See intermodal insurance and our guide to UIIA insurance requirements.
• Box trucks and hotshots. Regional and expedited work, CDL and non CDL. See box truck insurance and hotshot insurance.
• Dump trucks. Aggregate and construction work, priced on job site exposure. See dump truck insurance.

Owner-operators leased to a carrier need a different structure, usually non-trucking liability rather than primary. If that is you, start with owner operator insurance. Hauling direct for shippers on your own authority usually means adding general liability, and your freight is covered by motor truck cargo.

Car hauling is where an independent agency earns its keep

There is a reason South Carolina has so many car haulers, and it is worth understanding if you are thinking about running one.

BMW’s plant in Spartanburg is the largest automotive exporter by value in the United States. In 2025 it exported close to 200,000 vehicles worth about $9 billion, and since 2014 it has shipped nearly three million, with most of that moving out through the Port of Charleston. Those vehicles do not fly to the coast. They go on trucks, roughly 200 miles, every working day, alongside the parts moving in and the share that stays in the country. That is a car haul lane that lives almost entirely inside one state, and it is why the work is here.

The insurance side is where it gets interesting. Car hauling is not underwritten like general freight. You are carrying a trailer full of new vehicles on an open deck, so your cargo limit has to be far higher than the $100,000 most brokers ask for, and the shipper usually sets the number rather than the regulator. Plenty of trucking markets simply will not quote it, and a new authority hearing no three times in a row often concludes the door is shut.

It is not. Several of the carriers we work with write car hauling in South Carolina on purpose, and knowing which ones today, at your limits, with your experience, is most of the job. Bring us a car haul quote that came back too high, or an application that got declined, and let us find out who actually wants the work.

South Carolina truck insurance FAQs

How much is commercial truck insurance in South Carolina?

For a single truck, most South Carolina policies we write land between $8,000 and $24,000 a year, which is roughly $665 to $2,000 a month. Box trucks and hotshots sit at the bottom, car hauling and container work at the top. The table above breaks it out by operation, and a quote gives you your real number in about a day.

How much does car hauler insurance cost in South Carolina?

Most South Carolina car hauler policies we place run $15,000 to $23,000 a year, or about $1,250 to $1,915 a month, for a single truck. It sits above general freight mainly because of the cargo limit rather than the driving, since a full deck of new vehicles is worth far more than the $100,000 a typical broker asks for. Your experience hauling cars specifically is the factor that moves it most.

Why is car hauling such a big part of South Carolina trucking?

Because BMW’s Spartanburg plant is the largest automotive exporter by value in the country, and most of what it builds leaves through the Port of Charleston. Getting the vehicles from the Upstate to the coast is a truck job, and it runs every working day, which supports a much bigger car haul community than a state this size would otherwise have. It also means the experienced underwriters know the lane.

Do I need special insurance to pull containers out of the Port of Charleston?

Usually yes. Pulling boxes normally means a UIIA agreement with the equipment provider, and that carries its own coverage and endorsement requirements including trailer interchange. Not every trucking market writes it, though Progressive is one that does in South Carolina. We place intermodal regularly and will set the policy up so it satisfies the agreement the first time.

I just got my authority in South Carolina. Will anyone write me?

Yes, and you have more choice here than in most states. Several of the carriers we work with write first year authorities deliberately rather than as an exception. What you plan to haul matters more than the fact that you are new, and car hauling in particular is worth a conversation before you buy the trailer. Call us and we will quote it across multiple markets the same day, and file the BMC 91X as soon as you bind.

What is the cheapest way to insure a truck in South Carolina?

By having it shopped properly rather than by buying the thinnest policy. South Carolina is competitive enough that the same operation can come back thousands of dollars apart between carriers, because each one weighs your commodity, your radius and your driver history differently. That spread is the opportunity, and it is the whole argument for using an independent agency instead of buying direct. Let us run yours and find out who wants it most.
