How flatbed rates are built: linehaul, fuel, tarp, and oversize

The rate confirmation is the financial version of the load plan. It should identify the parties, pickup and delivery windows, commodity, weight, dimensions, trailer, total compensation, and each extra service. An all-in figure is not necessarily a complete quote: it may hide tarp labor, permits, or an unloading obligation that later becomes a dispute.

Linehaul and market pricing

Linehaul is the base movement charge, quoted as a flat amount or cents per loaded mile. Flatbed linehaul varies by lane and season. Flatbed earns a premium because equipment is less interchangeable, securement takes time, weather exposes the freight, and the carrier may reposition a specialized trailer empty.

Spot pricing is what a qualified carrier will accept today based on truck availability, reload prospects, weather, project deadlines, and the load board. Contract pricing is a negotiated lane rate supported by recurring volume and predictable tendering. It is commonly lower than an urgent spot quote but gives the shipper capacity and a service standard. A shipper with eight loads per month can exchange some market upside for fewer falloffs.

The flatbed-van spread is a useful market signal. When construction season, harvest, or a major project absorbs open-deck equipment, flatbed tightens first because a van cannot substitute for a flatbed. A low van index does not automatically make a flatbed lane cheap.

Fuel surcharge

Many carriers use the Department of Energy weekly diesel index and an agreed matrix. For example, a matrix might pay $0.40 per mile when DOE national diesel is $4.00 per gallon and $0.32 when it is $3.50. Breakpoints differ by contract, but the FSC normally sits on top of linehaul and moves weekly. Diesel is far above those example breakpoints today: the EIA’s U.S. on-highway average was $6.276 a gallon for the week of October 19, 2026, and DAT put the average flatbed fuel surcharge at $1.01 a mile in September 2026. Ask whether “$3.20 per mile” means linehaul only or includes fuel; otherwise two quotes cannot be compared.

Line item	What it covers	Typical range	Negotiable?
Linehaul	Tractor and trailer movement	Varies by lane and season	Yes
Fuel surcharge	DOE-indexed diesel	Set by a DOE diesel matrix; DAT flatbed average $1.01/mile, Sept. 2026	Formula usually fixed
Tarp	Driver labor and cover	Usually billed separately; write the fee on the rate confirmation and the BOL	Yes
Permit	State oversize authorization	Set by each state: $16 (CA) to $97 (PA, over 14 ft wide), plus weight charges	Fee is pass-through
Pilot car	Escort vehicle and labor	Quoted by the escort service; ATS tariff floor $1.05/mile and $125/day per escort	Route dependent
Layover	Overnight delay	$250 (ATS) to $900 (Melton) per night in posted tariffs	Yes
Driver assist	Additional labor	Priced per load or per stop; write it on the rate confirmation	Yes
Extra stop	Stop beyond one pickup/delivery	$75–$125 for the first stop; often more for each added stop	Yes

Tarp, permits, and escorts

Tarping is usually billed as a separate fee and should be written on the rate confirmation and the BOL. The confirmation should identify the tarp type, quantity, and fee. “Tarp if needed” is not a usable instruction. The full specification is in /guides/flatbed-tarping-guide.

The federal government does not issue oversize or overweight permits; the FHWA calls this a state option. Each state on the route issues its own permit under its own rules.

Oversize permit fees are set by each state and change with width, height, length, and weight. Caltrans charges $16 for a single trip. PennDOT charges $46 for a load under 14 feet wide and $97 above that, plus 4 cents a ton-mile when the load is overweight. Ohio charges a $10 processing fee plus $55 for a load up to 14 feet wide and 14 feet 6 inches high. Escorts are billed separately; Anderson Trucking Service’s rules tariff sets a floor of $1.05 a mile per escort and $125 a day. Width, height, length, axle spacing, and route drive the number. State thresholds are not uniform, so the confirmation should identify who applies, who advances the money, and how permit delays are handled.

Accessorials and short lanes

Layover applies when the shipper or receiver prevents same-day loading or delivery. Published flatbed tariffs put it at several hundred dollars a night: Landstar bills a held flatbed at $80 an hour up to $500 per 24-hour day (2020), and Melton Truck Lines charges $900 for a single-driver overnight layover (2023). Driver-assist labor may include unbanding, tarp removal, dunnage, or physical unloading. Carriers price it per load or per stop rather than by the hour, and some flatbed tariffs leave unloading to the receiver, so get the price on the rate confirmation. Extra stops beyond one pickup and one delivery are priced per stop, and the charge often rises with each one: Landstar lists $75 for each of the first three (2020), and Melton lists $125, $200, $300 and $450 for the first four (2023). Detention should have a clock trigger, signed in/out times, and a stated hourly rate; the related guide is /guides/detention-flatbed-loads.

Carriers put a floor under short moves. Melton Truck Lines’ rules set a minimum truckload charge of $850, and Anderson Trucking Service’s tariff sets $1,000 per truckload for most U.S. points. On a 250-mile move, a $1,000 minimum works out to $4.00 per loaded mile, but that is not a long-haul market rate. It pays for dispatch, positioning, securement, fuel, appointment time, and the carrier’s lost opportunity on a short day.

ATRI’s 2026 update put the industry-average cost to operate a truck at $2.336 a mile in 2025, or $1.854 a mile excluding fuel.

Build a quote from the numbers

Suppose linehaul is $3.20 × 800 miles = $2,560. An FSC of $1.00 × 800 adds $800. Add a $250 tarp and $180 in permits, and the documented subtotal is $3,790 before delay. A $3,900 all-in quote is attractive only if it includes the same tarp, permit, and fuel assumptions. If it excludes escort or pays detention only after four hours, it is not comparable.

For contract lanes, also examine empty miles and return likelihood. A carrier moving a load from Ohio to Texas may price the outbound differently if Texas has poor reload density for that trailer type. A reliable shipper with clean appointments can earn a better rate than an equally distant shipper that routinely holds trucks three hours. Service friction is part of a carrier’s cost model.

Read before signing

Confirm pickup and delivery windows, cargo weight, dimensions, trailer, tarp obligation, securement labor, permits, pilot cars, layover, detention, cancellation, and unloading responsibility. “Rate includes all accessorials” may erase legitimate permit or delay reimbursement. “Detention after two hours with signed arrival and release times” creates a workable process.

Do not let the BOL contradict the confirmation. If the BOL says full tarp coverage while the rate confirmation says no tarp, the driver is caught between conflicting instructions. Keep written approval for a changed destination, extra stop, revised dimensions, or a receiver-directed unload. For claims and surface protection, review /guides/flatbed-cargo-insurance; for tarp labor, use a line item rather than a verbal promise.
