Motor carrier classes by state

South Carolina hot shot trucking insurance for light-combination and expedited freight operators

South Carolina’s motor carrier safety rule is a single paragraph. It adopts the federal safety and financial responsibility parts, applies them to intrastate as well as interstate carriage, names common, contract, exempt and private carriers alike, and writes no weight of its own anywhere in the sentence. Four years ago the Legislature went the other way on the economic side and took general property out of its certificate statute entirely.

Flatbed dually towing a gooseneck flatbed trailer loaded with logs — South Carolina Hot Shot Trucking Insurance from Truck Guard Insurance

The features of the work that do not vary by jurisdiction — a delivery promise measured in hours, securement that changes with every deck, a limit written against the ordinary load and then met by the extraordinary one — are treated at hot shot trucking insurance, which is the right place for them.

South Carolina’s own material is a study in two regulatory tracks pulling in opposite directions. On the safety side, S.C. Code Regs. R.38-424 makes the federal safety text apply “to all motor carrier vehicles engaged in interstate commerce and intrastate commerce over the highways within the State of South Carolina, whether common carriers, contract carriers, exempt carriers, or private carriers”. On the economic side, 2022 Act No. 214 struck the words “or property” out of the statute that requires a certificate and put “hazardous waste for disposal, or household goods” in their place.

Those two facts have to be read together, and reading either one alone produces a wrong answer. A summary that says South Carolina has no weight floor is correct about the regulation and misleading about the operator: the rule writes no number of its own, so the number comes from the adopted federal text, and it is not zero. A summary that says South Carolina deregulated intrastate freight is correct about the certificate and silent about a heavily regulated safety obligation that runs to the same carrier at the same time.

Each figure below names the instrument that fixes it, the version this page read, and the amendment that produced it. The safety rule was last changed effective May 27, 2022. The certificate statute was changed effective May 23, 2022 — four days earlier, by a different body, on an unrelated clock.

Running freight inside South Carolina with no state certificate? That is the correct posture after the 2022 amendment — and it does not thin the safety obligation by a line, because the rule that adopts the federal text names exempt carriers on its face.

Give us the power unit’s rating, the rating of the heaviest deck you pull, whether any dispatch crosses into Georgia or North Carolina, and what your most valuable load is worth. The last of those is the one South Carolina leaves entirely to you.

One paragraph, no weight in it, and why the number is not zero

The whole of South Carolina’s motor carrier safety adoption is a single sentence, and it is worth reading in full because every clause in it is doing work. S.C. Code Regs. R.38-424 provides:

“The rules and regulations adopted by the United States Department of Transportation relating to safety of operation and to equipment (49 CFR Parts 382, 383, 385, 387, and 390-399 and amendments thereto), and the rules and regulations adopted by the United States Department of Transportation relating to hazardous materials (49 CFR Parts 107 and 171-180 and amendments thereto) shall apply to all motor carrier vehicles engaged in interstate commerce and intrastate commerce over the highways within the State of South Carolina, whether common carriers, contract carriers, exempt carriers, or private carriers, except where these aforementioned rules and regulations may conflict with South Carolina Law, provided that any rule or regulation which fixes the minimum age of vehicle drivers at 21 years is hereby changed insofar as South Carolina intrastate carriers are concerned to establish a minimum age of 18 years for vehicle drivers.”

There is no weight anywhere in that sentence, and the phrase it uses for the covered object — “motor carrier vehicles” — is not defined by South Carolina. The search for a definition was run and it came back empty, with the sources named. R.38-400 is a promulgating-authority provision and carries no definitions. R.38-401 states that the rules “shall apply to any person, firm, partnership, association, or corporation which is now or may hereafter become engaged as a motor carrier for hire within the State of South Carolina except where specifically exempt by statute”, and carries no weight.

R.38-423, the definition section for this very subarticle, defines the carrier and not the vehicle: “The term ‘motor carrier’ means every corporation or person, their lessees, trustees, or receivers, owning, controlling, operating, or managing any motor propelled vehicle used in transporting persons or property over any improved public highway in this State, whether or not for compensation … and includes but is not limited to, motor vehicle carriers as defined in Section 58-23-10 and private carriers.” And S.C. Code § 58-23-10(4) defines “motor vehicle carrier” as a person as well, with no weight element and no companion vehicle definition.

That absence is the mechanism, and it produces a specific result rather than an empty one. With no South Carolina definition of the covered vehicle, the vehicle scope comes from the adopted federal text itself, which carries its own definition of the vehicles the adopted parts apply to. So the correct statement about South Carolina is not that no weight binds this operator. It is that South Carolina writes no weight, and therefore the federal line arrives unmodified — the state supplied the adoption and the federal text supplied the number.

One further clause in R.38-423 sharpens the reach: the definition applies “whether or not for compensation”. A private carrier hauling its own material on a light combination is inside the South Carolina safety rule on the same terms as a for-hire operator, which is not true in every neighboring state.

The hedge that travels with every citation on this page

R.38-424 does not adopt the federal text unconditionally, and the qualifier it attaches is short enough to read past and consequential enough that it has to travel with every figure taken from the rule.

The words are “except where these aforementioned rules and regulations may conflict with South Carolina Law”. That is a conflict rule embedded in the adoption itself, and it is written in the direction of the state rather than of the federal text — where the two collide, South Carolina law is what survives.

In practice the conflict clause is rarely the operative provision, because South Carolina makes exactly one express change to the adopted text and it is stated in the same sentence. But it is the reason a page like this cannot present the adopted federal parts as if they applied in South Carolina in identical terms. They apply subject to a carve-out whose contents are not enumerated anywhere and are resolved case by case against the state’s own statutes.

R.38-401 adds a second, procedural qualifier in the same spirit: “These rules are subject to such exceptions as may be considered just and reasonable by the Director, or his designee, in individual cases when strict compliance with any rule or rules produces unusual difficulty and is not in the public interest.” An individual waiver power sits above the whole subarticle.

The same rule then places itself in the hierarchy: the rules “are considered supplementary to the statutes contained in Chapter 23 of Title 58 of the Code of Laws of South Carolina, 1976.” Supplementary to a statutory chapter that, as described below, was narrowed in 2022 — which is a large part of why the safety rules and the economic statutes now describe different populations.

“Exempt carriers” is named on the face of the rule

Three words in R.38-424 close a gap that would otherwise be the most natural argument an operator could make, and they are worth isolating because they are easy to skim.

The rule applies “whether common carriers, contract carriers, exempt carriers, or private carriers”. Exempt carriers are named as a covered class. An operator who is exempt from South Carolina’s economic regulation — which, after 2022, a general-freight carrier is — is expressly inside the safety adoption anyway.

That closes the inference that exemption from one track carries over into the other. The two tracks are administered by different bodies: the safety rules sit in the State Transport Police regulations under the Department of Public Safety, and the certificate regime sits with the Public Service Commission and the Office of Regulatory Staff. Exemption granted by one has never been exemption granted by the other, and R.38-424 says so rather than leaving it to be worked out.

The practical form this takes is a submission that looks lighter than it is. An operator with no state certificate, no filing with the Department, and no docket number is nevertheless answering to the full adopted safety text — driver qualification, hours, parts and accessories, inspection and maintenance, drug and alcohol testing, and the financial responsibility part — inside South Carolina.

It also means that the absence of a state filing is not evidence of anything about the account. In a state where the certificate class has been narrowed to household goods and hazardous waste for disposal, the presence or absence of a South Carolina filing tells an underwriter what the carrier hauls, not how it is run.

  • Common carriers, contract carriers, exempt carriers and private carriers are all named in R.38-424.
  • Economic exemption does not carry into the safety track, and the rule forecloses the argument by naming the class.
  • The safety track sits with the State Transport Police; the certificate track sits with the Public Service Commission and the Office of Regulatory Staff.
  • R.38-423 reaches carriers “whether or not for compensation”, so private carriage is inside as well.

Send the power unit and heaviest trailer ratings separately, the radius distribution, and what your heaviest actual load is worth. In a state that files nothing for cargo on a general-freight carrier, the third answer is the one that has no fallback.

The adoption is rolling, and it says so twice

Many states freeze the federal text at a stated edition. South Carolina does the opposite, and it makes the choice explicit rather than leaving it to inference.

R.38-424 adopts the safety parts “and amendments thereto”, and then adopts the hazardous materials parts “and amendments thereto” a second time in the same sentence. Twice-stated rolling language, no edition date, no revision date, and no “as in effect on” anywhere in the rule.

For an operator the consequence is direct. When the federal safety text is amended, the amendment reaches an intrastate South Carolina carrier through this rule without any state rulemaking having to occur. There is no lag and no state instrument to check for currency, which makes South Carolina easier to reason about than a fixed-edition state and harder to date a claim against.

The rule carrying that rolling language is itself dated on its own history block, and the two dates are different things. R.38-424 was added by State Register Volume 22, Issue No. 3, effective March 27, 1998, and amended by State Register Volume 46, Issue No. 05, effective May 27, 2022. So the sentence quoted throughout this page has been in its current form since May 2022, while the federal text it points at has moved several times since.

It is worth saying what that does not mean. Rolling adoption does not import federal provisions the rule did not name. The list is enumerated — specific safety parts, and specific hazardous materials parts — and a federal part outside the enumeration is not adopted into South Carolina intrastate law by this rule at all, however it may be amended.

One modification, and it is about age rather than hours

R.38-424 is a single paragraph, so the claim that it changes the adopted text in exactly one place is supported by reading the entire adopting instrument rather than by sampling it. It was read in full for this page, and the change is this: “provided that any rule or regulation which fixes the minimum age of vehicle drivers at 21 years is hereby changed insofar as South Carolina intrastate carriers are concerned to establish a minimum age of 18 years for vehicle drivers.”

That is a driver-age change, stated generally rather than tied to a weight band, a commodity, or a configuration. It reaches South Carolina intrastate carriers as a class. It also carries no conditions of its own — no placarding condition, no equipment condition, no radius condition beyond the word “intrastate”.

The hours-of-service part is inside the adopted block and is not touched anywhere in the paragraph. So an intrastate South Carolina carrier answers to the adopted hours rules as they stand, including the short-haul provisions, with no state variation and no state-declared agricultural window.

The age change also does not bind an insurer, and the distinction matters commercially. South Carolina declining to require twenty-one is a licensing position. Whether a program will write a driver in that age range, on what experience minimum, and with or without a named-driver restriction, is decided on the underwriting side against loss experience. A carrier hiring at eighteen in South Carolina is lawful and is also more expensive to insure, and both statements are true at once.

For a light combination the practical effect is worth stating plainly. The driver file an intrastate South Carolina operator has to hold is the full adopted file. The state has removed a single eligibility criterion from it and left everything else in place, which is a much narrower concession than the phrase “no state weight floor” tends to suggest to a reader encountering it in a summary.

In 2022 the state took general property out of its own certificate statute

The economic side of South Carolina moved recently and decisively, and the amendment notes on the Legislature’s own host record exactly what changed.

S.C. Code § 58-23-20 now reads: “No corporation or person, his lessees, trustees, or receivers may operate a motor vehicle for the transportation of persons, hazardous waste for disposal, or household goods for compensation on an improved public highway in this State except in accordance with the provisions of this chapter”. The effect-of-amendment note beneath it records that 2022 Act No. 214, Section 1, effective May 23, 2022, “in the first sentence, substituted ‘, hazardous waste for disposal, or household goods’ for ‘or property’”.

The same Act carried the change through the rest of the chapter rather than leaving inconsistent language behind. Section 58-23-30 defines “for compensation” for purposes of § 58-23-20 as payment “for transportation of persons, hazardous waste for disposal, or household goods”, rewritten by the same Act. Section 58-23-40, the certificate-and-fee section, makes the same substitution in both of its limbs, so that a carrier must obtain a certificate before transporting persons, hazardous waste for disposal, or household goods for compensation — and before advertising as an operator for that transportation.

Section 58-23-25 states the negative directly and was itself touched by the same Act: “Nothing in this chapter, unless specifically provided, may be construed as granting authority to the Public Service Commission to regulate, approve, fix, or charge a fee on a matter of rates, prices, changes, routes, or services of a motor vehicle carrier of property, including private carriers, except certificate carriers of household goods or hazardous wastes for disposal.”

So the answer for a general-freight intrastate operator is that South Carolina requires no certificate, no permit and no economic filing — not because an exemption was written for the work, but because the class the statute reaches was narrowed until it no longer described it. That is a firmer answer than an exemption, since an exemption can be repealed while a definition has to be re-expanded by the Legislature.

One definitional detail in the same chapter is worth carrying for this class specifically. Section 58-23-10(5) provides that a “trailer” means a vehicle equipped to carry a load and attached to and drawn by a motor vehicle, and that “trailers shall be classed as motor vehicles and subject to the provisions of Articles 1 to 11 of this chapter.” In South Carolina’s statutory vocabulary the deck is itself a motor vehicle, not an accessory to one.

The insurance schedule is gated on a certificate you will not hold

South Carolina publishes its own schedule of minimum liability limits, and the most important thing to know about it is the sentence that decides who has to file against it.

R.38-412(1) opens: “Before any certificate can be issued and before any motor carrier operations can be conducted thereunder, the motor carrier must file with and have accepted by the Department evidence of insurance policy or surety bond in the amounts hereinafter prescribed”. The duty is expressly tied to the issuance of a certificate and to operations conducted under it. A general-freight carrier holds no South Carolina certificate after the 2022 amendment, so the filing duty in this rule does not attach to it.

The schedule those words point at is R.38-414, and it is set out as a table for freight — “All motor vehicles used in the transportation of property.” Its first tier is “10,000 OR MORE POUNDS GVWR”, carrying $750,000 per incident for non-hazardous freight, $5,000,000 per incident for the explosives, liquefied and compressed gas and highway route controlled radioactive class, and $1,000,000 per incident for the intermediate oil and hazardous substances class. Its second tier is “LESS THAN 10,000 POUNDS GVWR”, carrying $300,000 per incident non-hazardous and $5,000,000 per incident for the explosives class. R.38-414 was added by State Register Volume 22, Issue No. 3, effective March 27, 1998, and its history block records no later amendment.

Two things about that table are useful even to a carrier it does not bind. It shows that when South Carolina sets its own weight break it puts it at 10,000 pounds rather than at the number the adopted federal text carries — the state schedule and the adopted text do not divide at the same place, and a page that rounded them together would describe a regime South Carolina does not have. And it shows there is no tier at which the schedule disappears: a light vehicle moves to the lower row rather than off the table.

What actually binds a general-freight intrastate carrier on liability is the financial responsibility part named inside R.38-424 and adopted by it to intrastate commerce. That part carries its own scope and its own weight provisions, and South Carolina has written nothing that displaces or extends them. This page therefore does not restate a figure as South Carolina’s requirement for this operator — the state’s own published schedule is above, with the certificate gate that keeps it off a general-freight account, and the operative amount comes from the adopted federal part rather than from a South Carolina table.

The gap between those two routes is smaller than it looks and is worth naming for completeness: the state schedule and the adopted federal part reach the same headline figure for non-hazardous freight above their respective weight breaks. The reason to keep them separate is not that they disagree today. It is that they are set by different instruments on different clocks, and only one of them is currently reaching this operator.

The cargo filing belongs to a class defined by what it carries

South Carolina does have a cargo insurance filing. It is attached to a certificate class, and the class is not this one.

R.38-415(1) provides: “Before any class E-LC certificate can be issued and before any motor carrier operations can be conducted thereunder, the class E-LC motor carrier must procure a cargo insurance policy or cargo surety bond and file with the Department evidence of such insurance or bond on forms prescribed by the Department”, with the policy conditioned on compensating shippers or consignees for loss of or damage to property coming into the carrier’s possession in connection with its transportation service within South Carolina. The minimum limits in the table beneath it are $2,500.00 for loss of or damage to property carried on any one motor vehicle and $5,000.00 for losses or damages occurring at any one time and place.

The class letters are the whole gate. A general-freight intrastate carrier holds no South Carolina certificate of any class, so it is not a class E-LC carrier and no cargo filing attaches to it.

South Carolina also runs a parallel class defined by cargo value, and it is worth quoting because it shows how the state thinks about this obligation. R.38-405 defines the Class E-L carrier as one hauling “commodities which are of extremely low value such as sand, gravel, dirt, fill dirt, rocks, hot and cold mix asphalt, borrow and any other commodities as determined by the Department and do not require cargo insurance.” R.38-415(2) carries the corresponding exception for carriers authorized to haul only commodities of extremely low value.

Read against this class of work, the contrast is the useful part. South Carolina’s cargo machinery is built around low-value bulk on one side and household goods on the other, and light-combination freight sits at neither end — it is high value per pound, moving under a rate negotiated per load, on a deck that may carry a single item worth more than the equipment beneath it.

So the cargo limit for a South Carolina hot shot is set entirely by the shipper agreement and by what the heaviest actual load is worth. There is no state floor to fall back on and no state schedule to point at in a dispute. That makes motor truck cargo a negotiated line in this state rather than a regulated one, and it makes the difference between an average load value and a worst-case load value the whole of the exposure.

The rules say out loud that they were written against federal preemption

Most states leave the federal preemption of intrastate freight economics invisible in their own text, so that the books read as though a certificate regime still reaches general property. South Carolina does the opposite and names the statute on the face of its rules.

R.38-400(3) provides: “These rules and regulations are consistent with Section 601, Pre-emption of Intrastate Transportation of Property, of the Federal Aviation Administration Authorization Act of 1994, enacted on August 23, 1994.” That sentence has been in the State Transport Police regulations since they were added effective March 27, 1998.

It is an unusual thing for a state to put in its own rule, and it changes how the rest of the South Carolina material reads. The narrowing of the certificate statute in 2022 was not an isolated policy choice arriving out of nowhere; it was the statutory side catching up to a boundary the regulatory side had acknowledged in writing twenty-four years earlier. The two tracks in this state are separated deliberately, and the separation is documented.

It also explains the shape of what survived. The classes still requiring a South Carolina certificate — passengers, household goods, and hazardous waste for disposal — sit on the side of the line where state economic authority was preserved, and the safety adoption in R.38-424 sits on the side where state authority was never in question. A reader who works only from the caption of the chapter would not see either boundary; a reader who opens R.38-400 sees the state naming it.

The practical value for an operator is a small one and a real one. When a broker, a shipper or a competitor asserts that a South Carolina certificate is required for intrastate freight, the answer is not an inference from silence. It is a 2022 amendment note on the Legislature’s own host, sitting above a 1998 rule that names the preemption statute by title and date.

How a South Carolina submission gets read

Rates on this class come out of judgment rather than a schedule, and a page that supplied one would be inventing it. What follows is the reading order for a South Carolina submission.

Cargo comes first, and it comes first because South Carolina has left it open. The state’s cargo filing belongs to a certificate class this operator does not hold, and the parallel low-value class exists for sand and gravel rather than for freight bought at a premium. The limit is therefore set by the shipper agreement and by the value of the heaviest load actually hauled — not the average one, which is the load that never generates the claim.

Radius and the state line come second. South Carolina applies the adopted safety text to intrastate and interstate carriage alike, so the safety file does not change at the border; what changes is the filing posture, the authority question and the rating basis. Charleston, Greenville, Spartanburg and the corridor between them sit close enough to Georgia and North Carolina that “intrastate” is a plan rather than a fact for many operations, and the honest answer to how far the trucks run is a distribution rather than a maximum.

The combination rating is third. South Carolina writes no number, so the state creates no threshold to sit under — but the rating still decides which side of the adopted federal text’s own line the operation falls on. The figure that counts is the one produced by the trailer hooked up on the day, and it moves whenever the fleet buys equipment.

Driver profile is fourth and is unusually live here. The state has moved its minimum age to eighteen for intrastate carriers as a class, without weight or commodity conditions. That widens the pool of lawful drivers and does nothing to the underwriting question, so the gap between what South Carolina permits and what a program will accept is wider in this state than in most.

Commodity mix is fifth, and it moves cargo limits more than liability. Light-combination work skews toward high value per pound — machine components, controlled-temperature goods, replacement parts bought at a premium precisely because something has stopped — and a limit set against an average shipment fails against exactly the shipment that produces a loss.

Underneath everything sits the paper. Leasing on rather than holding one’s own authority moves the first line of defense. A shipper that requires insured status on the operator’s policy moves it again; wording that puts that policy ahead of every other without contribution moves it a third time; and a recovery right conceded at onboarding quietly surrenders something nobody costed. None of those changes a specification. Where a state has withdrawn from economic regulation, that paper is the only floor there is. Securement and commodity questions usually arrive alongside it, and they are set out on the general freight and flatbed pages.

  • Cargo value on the heaviest load actually carried, since no South Carolina cargo filing attaches to a general-freight carrier.
  • Radius as a distribution, and whether dispatches cross into Georgia or North Carolina.
  • Whatever combination rating the trailer in service actually produces.
  • Driver ages and tenure, given the state’s eighteen-year minimum for intrastate carriers and how underwriters price it separately.
  • Commodity mix and value per pound rather than weight alone.
  • Whose authority the trucks run under, and the insurance conditions written into the shipper agreements.

The limits of the negative, stated rather than hidden

Being accurate about the absences matters as much as the text, and one of them here is a limit on the research rather than a finding about the state.

There is nothing in South Carolina addressed to this work by name — no term, no certificate class, no schedule and no required endorsement. Search the state material for the language operators actually use for the business and it returns nothing.

South Carolina declares no planting-and-harvesting season and writes no air-mile variation in the adopting rule. R.38-424 is a single paragraph and it was read in full; the only change it makes to the adopted text is the driver-age change quoted above. The adopted hours part therefore applies to intrastate carriage as it stands.

South Carolina requires no operating authority for intrastate general freight, and no cargo filing attaches to a carrier holding no certificate. Both of those rest on sections read in the statutory chapter and on the certificate gates printed in R.38-412 and R.38-415.

And here is the limit on the negative. The State Transport Police regulations were not enumerated. Both index paths for the relevant article return the wrong document at the host used, so the true count of rules in that article cannot be stated and is not guessed at here. The claim that South Carolina writes no weight of its own rests on the seven rules that were read in full — R.38-400, R.38-401, R.38-405, R.38-412, R.38-414, R.38-415 and R.38-424 — together with the statutory definitions section, and not on an exhaustive read of the article. That is a weaker denominator than this page would prefer, and it is stated rather than hidden.

What is not in doubt is the structure. South Carolina regulates this work heavily on safety and not at all on economics, and it has been explicit in both directions — naming exempt carriers as covered in the safety rule, and naming the federal preemption statute in the rule that authorizes the rest.

Coverage lines a South Carolina hot shot account usually carries

The state minimum is a licensing threshold. The program an operator actually needs is built from these lines:

  • Trucking Auto Liability — Primary liability coverage for bodily injury and property damage caused by your truck while under dispatch.
  • Physical Damage — Collision and comprehensive coverage for the tractor, trailer, and attached equipment you own or finance.
  • Motor Truck Cargo — Coverage for the freight you haul against loss or damage in transit.
  • Trailer Interchange — Coverage for non-owned trailers you pull under written interchange agreements.
  • General Liability — Coverage for premises and operations liability away from the truck — terminal yards, customer docks, and non-driving exposures.
  • Workers Compensation — Statutory coverage for driver and yard-employee injury, structured for trucking payrolls and interstate operations.
  • Non-Trucking (Bobtail) Auto Liability — Liability coverage for the tractor when operated off-dispatch — bobtailing home or running personal errands.
  • Pollution Liability — Coverage for cargo-related pollution events and upset/overturn spills not covered by standard auto liability.

Why Truck Guard Insurance for a South Carolina hot shot account

We write hot shot and expedited hauling as a named class rather than as an exception to general trucking, and we read each account against the weight and authority regime of the state it operates in. For a South Carolina operator that means starting from the rating of the power unit and the trailer separately rather than from the combination, sizing cargo against the heaviest load actually carried rather than the average one, and treating the state line as a rating fact because a single crossing can change which driver file the operation owes.

If the operation also runs freight under separate authority, the South Carolina trucking insurance page covers the state’s broader motor carrier picture, and the hot shot trucking insurance page covers the class mechanics that apply wherever the operator runs.

South Carolina hot shot trucking insurance questions

Does South Carolina set a weight floor for intrastate motor carrier safety rules?

It writes none of its own. S.C. Code Regs. R.38-424 applies the adopted federal safety and hazardous materials parts “to all motor carrier vehicles engaged in interstate commerce and intrastate commerce over the highways within the State of South Carolina, whether common carriers, contract carriers, exempt carriers, or private carriers”, with no weight anywhere in the sentence. Because the state supplies no definition of the covered vehicle, the vehicle scope comes from the adopted federal text itself — so “no state floor” does not mean no floor. Read August 31, 2026.

Does an intrastate freight carrier need a South Carolina certificate?

No, not since 2022. S.C. Code § 58-23-20 now reaches only “persons, hazardous waste for disposal, or household goods”, and the effect-of-amendment note on the Legislature’s own host records that 2022 Act No. 214, Section 1, effective May 23, 2022, substituted that phrase for “or property”. Sections 58-23-30 and 58-23-40 were amended to match, and § 58-23-25 forecloses commission authority over a motor vehicle carrier of property except certificate carriers of household goods or hazardous wastes for disposal.

If a carrier is economically exempt in South Carolina, is it outside the safety rules too?

No, and the rule closes that argument by naming the class. R.38-424 applies “whether common carriers, contract carriers, exempt carriers, or private carriers”. The two tracks are administered by different bodies — safety by the State Transport Police under the Department of Public Safety, certification by the Public Service Commission and the Office of Regulatory Staff — and exemption from one has never carried into the other. R.38-423 goes further and reaches carriers “whether or not for compensation.”

Which edition of the federal safety text applies in South Carolina?

Whichever is current. R.38-424 adopts the safety parts “and amendments thereto”, and adopts the hazardous materials parts “and amendments thereto” a second time in the same sentence. There is no edition date, no revision date and no “as in effect on” language anywhere in the rule, so federal amendments reach an intrastate South Carolina carrier without state rulemaking. The rule itself was added effective March 27, 1998 and amended effective May 27, 2022 on its published State Register history.

What does South Carolina change about the federal rules?

One thing. R.38-424 is a single paragraph, read here in full, and its only modification is that “any rule or regulation which fixes the minimum age of vehicle drivers at 21 years is hereby changed insofar as South Carolina intrastate carriers are concerned to establish a minimum age of 18 years for vehicle drivers.” The hours-of-service part sits inside the adopted block untouched, so the adopted hours rules and their short-haul provisions apply to intrastate carriage without state variation.

Does South Carolina require a cargo insurance filing?

Not from a general-freight carrier. R.38-415 attaches the cargo filing to the class E-LC certificate: “Before any class E-LC certificate can be issued and before any motor carrier operations can be conducted thereunder, the class E-LC motor carrier must procure a cargo insurance policy or cargo surety bond and file with the Department evidence of such insurance or bond”, with minimums of $2,500.00 per motor vehicle and $5,000.00 per occurrence. A carrier holding no South Carolina certificate holds no class, and no cargo filing attaches.

What are South Carolina’s published minimum liability limits, and do they apply to me?

R.38-414 sets a freight schedule with two tiers: at 10,000 or more pounds GVWR, $750,000 per incident non-hazardous, $5,000,000 for the explosives and compressed gas class and $1,000,000 for the intermediate class; below 10,000 pounds, $300,000 per incident non-hazardous and $5,000,000 for the explosives class. But R.38-412(1) gates the filing duty on certification, and a general-freight carrier holds no certificate — so what binds it is the financial responsibility part adopted to intrastate commerce by R.38-424, with that part’s own scope provisions.

Do South Carolina’s rules acknowledge federal preemption of intrastate freight?

Yes, in terms. R.38-400(3) provides: “These rules and regulations are consistent with Section 601, Pre-emption of Intrastate Transportation of Property, of the Federal Aviation Administration Authorization Act of 1994, enacted on August 23, 1994.” That sentence has been in the State Transport Police regulations since they took effect on March 27, 1998, which is why the 2022 narrowing of the certificate statute reads as the statutory side catching up rather than as a new policy.

How much does hot shot insurance cost in South Carolina?

This class is not priced from a schedule, and any number produced without the operation in front of you would be made up. Start with the value of the heaviest-value deck the operation actually loads, since no state cargo filing reaches a general-freight carrier; then the spread of dispatch distances and how often one crosses into Georgia or North Carolina; the rating the trailer in service produces; commodity mix and value per pound; how long the drivers have held their licenses, given the state’s eighteen-year minimum; whose authority the trucks run under; and the insurance conditions written into the shipper agreements.
