Oversize Load Boards: How to Find Heavy Haul Loads

Material broker-security and authority claims reviewed October 23, 2026 against FMCSA and current eCFR sources. Business-channel examples are not earnings or payment guarantees.

Oversize freight reaches you through four channels: load boards, freight brokers, direct shippers, and other carriers. A federally registered property broker must maintain $75,000 in financial security through a surety bond or trust fund. Verify the broker’s authority and filing before accepting its load; that security does not guarantee your particular invoice will be paid.

On This Page

This guide covers all four channels and how to vet each one.

In one minute: start on a load board to see what moves on your lanes, then build direct relationships. The money in heavy haul is in repeat work from shippers who know your deck and your permits.

Before you accept any load from a broker, check the bond and read the rate confirmation.

Where does oversize freight come from?

Four channels, and they overlap. Load boards list freight posted by brokers and by shippers, while brokers arrange transportation for a shipper without owning any trucks. Direct shippers post their own freight, and other carriers pass along overflow work they cannot cover themselves.

Most new drivers start on a board and move toward direct work.

Heavy-haul freight is a smaller pool than dry van.

That works in your favor once people know your equipment.

How do you check out a broker?

Verify active broker authority and financial-security filings through FMCSA’s official registration resources, then match the business identity to the rate confirmation. The $75,000 security is not reserved for your invoice, and other claims or insolvency can affect recovery. Independently confirm the booking and payment instructions rather than relying only on a document sent by a caller.

Regulation, verbatim

"A broker must have a surety bond or trust fund of $75,000 in effect." — 49 CFR 387.307. Verified September 8, 2026.

The bond exists to pay shippers or motor carriers when the broker fails to carry out its agreements. You are one of the parties it protects.

Can you see the broker's records?

Yes, and federal rule says so plainly. Every broker must record who shipped the load, which carrier moved it, and what the broker was paid for arranging it. Each party to that transaction may review the record, and you are a party to it.

Regulation, verbatim

"Each party to a brokered transaction has the right to review the record of the transaction required to be kept by these rules." — 49 CFR 371.3(c). Verified September 8, 2026.

Brokers must keep that record for three years, so a dispute six months old is still documented.

Four channels that carry oversize freight to a driver Four channels lead to one truck: a load board, a freight broker, another carrier and a direct shipper. A registered property broker maintains financial security through a bond or trust fund. Each channel needs its own identity, agreement and payment checks; the diagram does not rank rates or guarantee which pays more.

The channel decides who takes a margin. It does not decide who is responsible for the permit.

Which Load Boards Support Heavy-Haul Searches?

Compare equipment fit and the work each tool actually performs. DAT One describes specialized trailer searches, including RGN, double-drop and multi-axle equipment. Truckstop’s dedicated Heavy Haul product combines oversize load search with planning rate and permit quotes. Check each provider’s current package and coverage before buying; these are examples, not a ranking. We reviewed the providers’ published information and did not test them on a haul.

Different Tools For Different Stages
ChannelUse It ForVerify Separately
DAT OneFind posted freight matching specialized equipment.The posting, counterparty, availability and complete movement scope.
Truckstop Heavy HaulSearch specialized freight and evaluate its advertised planning tools.Quote assumptions and the actual issued permit conditions.
Direct Shipper Or CarrierQualify a real customer’s movement or an established assignment.Who can book it, what equipment is needed and who pays.
RouteAllReview an issued permit and navigate its checked route after booking.Business identity, booking terms and state travel authority. RouteAll is not a load board.

Start with three candidate loads that fit your actual combination, rather than comparing a board’s total posting count. Check the load facts, callback the verified business, confirm timing and access, then compare the complete job against your availability and costs. A planning estimate does not issue the permit.

Looking for employment rather than freight for your carrier? Use heavy-haul driver jobs. For a candidate movement, follow the booking checklist and broker verification steps. To build another channel, read direct shipper relationships.

What should you ask before quoting?

Five questions, and the dimensions come first. You cannot price an oversize load without knowing what it measures, who buys the permits, and how many states it crosses. A rate that looks strong before permits and escorts can be a loss after them.

  1. Dimensions and weight. Get width, height, length and gross weight in writing, not by phone.
  2. Who buys the permits. Some shippers permit the load; often the carrier does. Confirm in the rate confirmation.
  3. Which authorities. Check the load and roads in each state, including separate local or facility permissions; do not assume one application per state.
  4. Escorts required. Escort cost is real money and the threshold changes at each state line.
  5. Loading and unloading. Ask who provides the crane and who takes responsibility for securement.

Quote the total, not the line haul. Permits, escorts and curfew delays are all costs the load carries.

The escort threshold is the number most often missed. Read the pilot car requirements by state before you name a price.

How do you get repeat work?

By being the carrier who does not create problems. Heavy-haul shippers move the same equipment on the same lanes, so they remember who delivered clean. Deliver on the permitted route, show up with the right flags and banners, and answer the phone when the escort calls.

Three habits earn the callback:

A shared RouteAll route opens for the escort with no account and no charge, so the escort reads the same roads you do. That is one fewer phone call before every move.

Specialize before you generalize. Two or three lanes you know well beat fifty you do not.

What should make you walk away?

Four warning signs, and any one of them is enough. A broker who will not name the bond, a rate that assumes no permits, dimensions that arrive verbally only, and a load already sitting on a trailer somebody else refused. Walk away is cheaper than a claim.

Warning

You must not move an oversize load on a promise that the permit is coming. The permit exists before the wheels turn, or you do not roll.

Ask for the dimensions in writing every time.

A load that measures 12 feet 4 inches when you were told 11 feet 6 inches is a different permit and a different escort bill.

The measurement is yours to verify at pickup.

Use This Check In RouteAll

Once the job is agreed, use RouteAll’s trip expense log to retain the costs you will reconcile with that haul. The console requires sign-in. Logging expenses does not establish a broker’s creditworthiness or replace your rate agreement.

How Do You Compare Load Boards For Your Actual Trailer And Lanes?

Prepare the same search in each provider’s demonstration: actual trailer configuration, usable deck, payload, authority, pickup radius, destination lanes and dates. Count suitable candidate movements rather than every posting. Record which critical facts still require a call and whether the listing remains available.

The DAT-versus-Truckstop comparison separates published features from an independent road test. It includes a demonstration checklist and shows where quoting, booking, permitting and permit navigation serve different decisions. One unusually good search is not evidence of a platform-wide success rate.

Before you roll

Start on a board, but do not stay there. Check the $75,000 bond before you haul for any broker, and get dimensions in writing before you quote. Evaluate repeat work by its actual rates, payment history and total trip costs. A repeat customer or a direct relationship is not, by itself, a payment or profitability guarantee.

Common questions

Do I need my own authority to haul oversize?

FMCSA generally requires interstate operating authority when a business transports federally regulated commodities owned by others for compensation. Exemptions and state requirements can change the answer. If operating for another carrier, verify the actual operating arrangement; an oversize permit does not replace required registration or authority.

How much bond must a freight broker hold?

Seventy-five thousand dollars. 49 CFR 387.307 requires every broker to keep a surety bond or trust fund of $75,000 in effect. It pays shippers and motor carriers when the broker fails to carry out its agreements, which means it exists partly to protect you.

Can I see what the broker was paid?

Yes. 49 CFR 371.3 requires brokers to record the compensation they received and who paid it, and gives each party to the transaction the right to review that record. Brokers must keep it for three years. Ask in writing if you believe a rate was misrepresented.

Who pays for the permits and escorts?

Settle cost responsibility in the written agreement before accepting the load. Identify every required permit and escort service for the actual roads and dimensions, including separate local or facility permissions. A general rate quote does not establish which costs are included or reimbursable.
