How to Start a Trucking Company in South Carolina: Step-by-Step Guide (2026)

Starting a trucking company means getting a lot of paperwork right, in the right order. Miss one filing and your authority can be dismissed, your $300 fee lost, or your truck parked at a weigh station.

This guide walks through every step for a new for-hire interstate carrier based in South Carolina hauling general freight. If you plan to haul hazardous materials or passengers, or only drive inside South Carolina, some steps will be different.

Quick checklist

Step 1: Decide on your business model

Before you file anything, decide how you will operate:

• Leased owner-operator. You own or finance the truck but run under another carrier's authority. The carrier provides the authority, insurance filings and often the freight. This is the fastest and cheapest way to start, and a good way to learn the business.
• Your own authority. You run under your own USDOT and MC numbers. You keep more of each load, but you are responsible for insurance, compliance, finding freight and getting paid.

Many owner-operators lease on first, then get their own authority once they have savings, customer contacts and a clean safety record.

Step 2: Form your business and get an EIN

Most small carriers form a limited liability company (LLC). It separates your personal assets from the business, which matters in an industry where one accident can lead to a large claim.

In South Carolina you file Articles of Organization with the South Carolina Secretary of State. You will need a business name, an address in the state and a registered agent.

Next, get an Employer Identification Number (EIN) from the IRS. It is free and you can apply online at IRS.gov. Watch out for websites that charge a fee for this.

Tip: Use your exact legal business name everywhere. FMCSA says the name on your operating authority application must match the name on your insurance filings, your BOC-3 and your USDOT record. A mismatch causes delays.

Step 3: Apply for your USDOT number and operating authority

Interstate for-hire carriers need two things from the Federal Motor Carrier Safety Administration (FMCSA):

1. A USDOT number, which identifies your company and tracks your safety record.
2. Operating authority (often called an MC number), which is permission to haul regulated freight for hire across state lines.

In 2026, FMCSA moved registration to a new online system called Motus. New carriers create a Login.gov account, set up a company account and apply for a USDOT number and operating authority in one application at motus.dot.gov. FMCSA's Registration Modernization Resources Hub has step-by-step guides and videos. For help, call FMCSA registration at 1-800-832-5660.

Key facts:

• FMCSA charges $300 for each type of operating authority, and the fee is non-refundable.
• After you apply, FMCSA publishes your application. You then have 90 days to get your insurance and BOC-3 on file, or the application is dismissed and the fee is not refunded.
• Getting an MC number assigned does not mean you can operate. You can start hauling only once your authority shows ACTIVE in FMCSA's Licensing and Insurance system.

Step 4: File your BOC-3 (process agents)

A process agent is a person or company in each state who can accept legal papers on your behalf. You list your agents on Form BOC-3. Most carriers hire a "blanket" process agent company that covers every state for a small one-time fee and files the BOC-3 electronically for you.

Step 5: Get commercial truck insurance

Your insurance company, not you, files proof of coverage with FMCSA. Federal minimums for for-hire carriers of property in vehicles of 10,001 pounds or more are:

• $750,000 for general (non-hazardous) freight
• $1,000,000 for oil and many hazardous materials
• $5,000,000 for certain high-risk hazardous materials, such as some bulk hazmat

These are only the legal minimums. Many shippers and freight brokers require more, commonly $1,000,000 of auto liability plus cargo coverage. Ask your agent about physical damage coverage for your truck, too. Your lender will likely require it.

New carriers often pay high premiums in the first year or two. Get quotes from several agents who specialize in trucking, and get them early. Insurance is often the biggest startup cost after the truck itself.

Step 6: Register for UCR

The Unified Carrier Registration (UCR) is an annual federal registration that interstate carriers pay each year, before January 1 of the registration year. The fee depends on how many trucks you operate. For 2026, carriers with 0 to 2 vehicles pay $46, according to the UCR fee brackets. Fees are set to rise for 2027.

Step 7: Get IRP plates and IFTA decals from SCDMV

If your truck crosses state lines, you will usually need:

• IRP (International Registration Plan) apportioned plates, which let you register once and pay registration fees to each state based on the miles you drive there.
• IFTA (International Fuel Tax Agreement) decals and an account, so you file one quarterly fuel tax return instead of one per state.

In South Carolina, both are handled by SCDMV Motor Carrier Services. A few things to know:

• The truck must be titled in your name or your business's name to open an IRP or IFTA account.
• IRP generally applies to vehicles that travel in two or more jurisdictions and weigh over 26,000 pounds or have three or more axles.
• SCDMV asks new carriers to allow about five business days for a reply after applying.
• Since May 2026, IFTA returns must be filed online or by mail to Motor Carrier Services headquarters. Branch offices no longer take them.

Step 8: File Form 2290 (heavy vehicle use tax)

If your truck has a taxable gross weight of 55,000 pounds or more, you must file IRS Form 2290 and pay the Heavy Highway Vehicle Use Tax. For the heaviest trucks, the full-year tax is $550.

The return is due by the last day of the month after the month you first use the truck on public roads. The tax year runs July 1 to June 30. You need the stamped Schedule 1 to register your truck for IRP plates, so file early.

Step 9: Set up drug and alcohol testing

Every carrier that employs CDL drivers, including an owner-operator who drives for their own company, needs a DOT drug and alcohol testing program. Most small carriers join a testing consortium that runs the random selections.

You must also:

• Register with the FMCSA Drug & Alcohol Clearinghouse.
• Run a pre-employment drug test and a full Clearinghouse query before any driver, including yourself, drives for you.

Not having a testing program or a random testing program is an automatic failure of your new entrant safety audit.

Step 10: Set up your safety records

From your first load, keep records for:

• Driver qualification files: application, motor vehicle record, road test or CDL copy, medical certificate and previous employer checks.
• Hours of service: most drivers must use an electronic logging device (ELD). See our hours of service guide.
• Vehicle maintenance: annual inspections, repairs and driver vehicle inspection reports.
• Accident register, if you have any crashes.

Step 11: Get ready for your new entrant safety audit

For your first 18 months, FMCSA treats you as a "new entrant" and watches your safety record closely. Within your first 12 months, FMCSA will do a safety audit of your records. Pass, and you keep your authority. Fail, and you have a short window to fix problems or your registration is revoked.

Step 12: Find freight and get paid

Once your authority is active, you can start finding loads:

• Freight brokers and load boards are where most new carriers start.
• Direct shippers usually pay better and are steadier, but take longer to win.
• Factoring companies pay your invoices within a day or two for a fee, which can help with cash flow while you wait 30 to 60 days for brokers to pay.

Some brokers prefer to work with carriers whose authority has been active for a few months, so plan your cash for a slow start.

Startup costs to plan for

Beyond the truck itself, budget for filing fees, insurance down payments, plates, ELD and testing program fees, fuel and maintenance. Insurance is often the biggest cost after the truck. Talk to an accountant who works with trucking companies before you buy equipment.
