What dedicated lane freight is
Dedicated lane freight is repeat truckload freight that moves under a contract: a fixed rate per lane, agreed for a set term, with carriers committed to cover it. A lane is a specific origin and destination pair with an equipment type, such as dry van from Chicago, IL to Atlanta, GA. If that lane ships three times a week every week, pricing each load separately on the open market makes little sense.
Under a dedicated lane program, the shipper shares its lanes, frequency and seasonality. The broker prices each lane, lines up carriers who want that freight on a schedule, and the rate holds for the term, whether that is a month, a quarter or a year. Each load still gets a rate confirmation, but nobody negotiates it from scratch. This is different from a dedicated fleet, where specific trucks and drivers work only for one shipper. A dedicated lane commits capacity and price to a route without tying a whole fleet to you.
Who contract lanes fit
Contract lanes fit shippers whose freight moves on a schedule, because a schedule is what lets a carrier plan trucks around it. The more regular the lane, the more a carrier will commit to it and the more stable the rate.
Retailers shipping from a distribution center to the same stores each week are a natural fit, and so are building materials producers sending product to the same yards through the season. Food and beverage plants with standing orders to grocery distribution centers fit, as do steel service centers and manufacturers with daily outbound to the same customers. Seasonal shippers can benefit too: a program written around the busy months gives carriers a reason to save trucks for you when the market is tight. Contract lanes fit poorly when freight is truly irregular, such as one-time project loads or shipments whose destinations change every week. Those belong on the spot market, priced load by load. Many shippers run both: contract on the steady lanes, spot for everything else.
Contract lanes vs spot vs dedicated fleet
The three ways to buy repeat truckload capacity differ in commitment, cost stability and how much control you get. The table compares them so you can see where a contract lane sits between the spot market and owning a fleet's time.
| Point | Spot market | Contract lanes | Dedicated fleet |
|---|---|---|---|
| Price set | Per load, that day | Per lane, for the term | Per truck, per week or month |
| Capacity | Whatever is available | Committed carriers per lane | Specific trucks and drivers |
| Cost stability | Moves with the market | Fixed for the term | Fixed, but you pay for idle time |
| Flexibility | Highest | Moderate | Lowest |
| Best for | Irregular freight | Regular lanes, weekly or daily | Very high, steady volume on short loops |
A spot rate can beat a contract rate in a soft market, and lose badly in a tight one. A contract trades that upside for predictable cost and trucks that show up.
A dedicated fleet sits at the far end. You pay for the trucks whether or not freight is ready, so it only pays off when volume fills them every day. Contract lanes give most shippers the stability without the idle cost, and spot remains the overflow valve.
How a routing guide works
A routing guide is the shipper's rule book for who gets each load: a ranked list of carriers or brokers for every lane, each with its contracted rate. When an order is ready, the load is tendered to the primary provider on that lane first. If the primary accepts, it moves at the contract rate. If the primary declines, the tender goes to the second provider, then the third, and only after the list runs out does the load go to the spot market.
The routing guide is where a contract either works or quietly fails. A provider that wins a lane in a bid but rejects most tenders pushes freight down the guide to backups at higher rates, so the price you awarded is not the price you pay. That is why tender acceptance, the share of tendered loads a provider actually takes, is the number to watch. A well-run program keeps backup capacity named on each lane, so a declined tender moves to a known carrier instead of a scramble.
What committed capacity means
Committed capacity means a carrier has agreed to cover a lane at a set frequency and rate for the term, and plans its trucks to do it. It is the difference between hoping a truck is available on Tuesday and knowing one is.
Commitment works both ways. The carrier commits trucks on the days your freight moves; you commit to tendering the volume you forecast. If you promise five loads a week and tender two, the carrier's planning falls apart and its next rate reflects that. If you tender eight, it may not have trucks for the extra three. Good programs spell out the expected weekly volume, how far above or below it the carrier will flex, and what happens outside that band. Capacity also needs depth. One committed carrier per lane is a single point of failure; a primary plus at least one backup carrier is safer. Ask who the carriers behind each lane are, and confirm each one is checked against federal registration records before the first load.
Designing a lane around the rules
A dedicated lane runs on the same federal limits as any truckload, and building the schedule around them is what makes the rate hold. The FMCSA hours of service rules (opens in a new tab) allow 11 hours of driving after 10 off, inside a 14-hour window. At the planning rule of about 550 miles a day for a solo driver, a lane's length sets how many days the truck is tied up.
| Lane | Road miles (approx.) | Solo transit | Round trip planning |
|---|---|---|---|
| Houston, TX to Dallas, TX | About 240 | Same day | 2 x 240 = 480 miles, often one driver's day |
| Chicago, IL to Atlanta, GA | About 715 to 730 | 2 days (730 / 550 = 1.3) | About 4 days (2 x 2) with a backhaul |
| Salinas, CA to Chicago, IL | About 2,200 | About 4 days (2,200 / 550 = 4) | About 8 days (2 x 4) or more |
A Chicago to Atlanta dry van lane shipping three times a week therefore needs several trucks in rotation, not one. Each truck is gone about four days per round trip, so three loads a week means at least two trucks committed to the lane, plus a backup. Weight follows the federal 80,000 lb (opens in a new tab) gross limit, so a lane loaded consistently near payload must stay that way.
Freight that fits a contract lane
The best contract freight is the same product, on the same lane, at the same rhythm, with predictable loading and unloading. Store replenishment from a retail distribution center is the textbook case: the stores do not move, the volume follows a pattern, and the docks run on appointments. Finished goods from a plant to a customer's warehouse on a standing order fit just as well.
Building products, such as packaged lumber, roofing and bagged material, move to the same dealers and yards all season, and suit seasonal programs. Steel and metals shippers, from service centers to fabricators, often run daily lanes that suit steel and metals contracts. Refrigerated food on a weekly schedule fits contract reefer programs, provided set points and pre-cooling are agreed up front. Freight that fits less well includes one-off machinery moves, project freight to a construction site, and anything whose destination changes week to week. Those still need a truck, but they are better priced on the day.
How a lane program gets built
A lane program comes together in a sequence that starts with your data and ends with a review, then repeats each term. The steps below follow a typical bid or RFP from file to first load.
- You send the lane file: origin, destination, equipment, volume per week or year and any seasonality.
- Each lane is priced with the capacity behind it, meaning named carriers who want that freight.
- You award lanes, and the rates and term are written down, with fuel handled one way or the other.
- Primary and backup carriers are set in the routing guide for each lane.
- Loads are tendered to the primary at the contract rate.
- Declined tenders move to the backup without renegotiating.
- Performance is reported on time and cost by lane.
- Quarterly reviews adjust rates, carriers or volume where the lanes ran differently from the plan.
Step 2 is where programs differ most. A rate with no carrier behind it is only a guess.
What drives a contract lane rate
A contract lane rate reflects how attractive the lane is to a carrier over the whole term, not on one day. Volume and consistency come first: a lane that ships the same days every week lets a carrier plan, and that is worth something in the rate. Lanes with volatile weekly counts cost more because the carrier must hold spare trucks.
Direction matters as much as distance. A lane into a market with plenty of outbound freight lets the carrier reload quickly; a lane into a thin market means empty miles home, which end up in the price. Equipment type matters, since reefers and flatbeds are scarcer than vans. Facility behavior counts: fast loading, drop trailers and firm appointments make a lane cheaper to serve, while long detention makes it dearer. Term length changes the risk each side carries. Fuel can be built into an all-in rate or handled through a fuel surcharge table, which keeps the line haul fixed while diesel prices move. Seasonality in your freight, or in the market, also shapes the rate.
What to put in a lane file
A lane file is the spreadsheet a contract is priced from, and the quality of the pricing follows the quality of the file. Any format works, but these fields should be in it.
- Origin and destination city, state and ZIP for each lane.
- Equipment: dry van, reefer with set point, or flatbed with securement notes.
- Volume per week, month or year, and how steady it is.
- Seasonal peaks and slow periods, with rough timing.
- Average weight and pallet count per load.
- Loading and unloading type: live, drop, floor-loaded or palletized.
- Facility hours and appointment rules at both ends.
- Accessorials you expect, such as stops, liftgate or lumper fees.
- Term you want, and whether fuel should be all-in or separate.
- Current pain points, such as rejected tenders or late pickups.
The pain points matter. If a lane keeps failing today, the new rate must fix the reason, not just the price. Check lane distances with the lane finder before you send it.
How Powerhaul runs dedicated lanes
We build dedicated lane programs around your lanes, frequency and seasonality, with committed carriers, set pricing and one point of contact who knows every load. If the freight moves on a schedule, it should be priced on one.
Terms run monthly, quarterly or annual. Pricing is fixed per lane, with fuel separate if you prefer, using fuel surcharge tables agreed up front. Each lane has committed carriers, and we name backup capacity so a declined tender does not become a scramble. We report on time and cost by lane, and hold quarterly reviews to adjust what the numbers show. We support bids and RFPs: send the lane file in any format and we will come back with pricing and the capacity behind it. Programs cover weekly and daily lanes and seasonal programs. Every carrier is checked against FMCSA records before it is booked, and the rate comes from a person who has studied your lanes, not from a formula. Lanes that load often pair well with drop trailer pools.
What the law requires of your broker
A contract lane program puts real volume in a broker's hands, so it is worth knowing the federal baseline every broker must meet. A broker is defined in 49 U.S.C. 13102 (opens in a new tab) as a person who arranges transportation by motor carrier for compensation, without carrying the freight itself.
| Requirement | What it means for you | Source |
|---|---|---|
| Financial security | $75,000 surety bond (BMC-84) or trust fund (BMC-85) | 49 CFR 387.307 (opens in a new tab) |
| Transaction records | Broker keeps a record of each transaction for three years | 49 CFR 371.3 (opens in a new tab) |
| Cargo liability | Carrier liability for loss and damage under the Carmack Amendment | 49 U.S.C. 14706 (opens in a new tab) |
Before awarding lanes, confirm the broker's registration and bond, and ask how carriers on each lane are vetted. The records rule means your contract history, rates and loads should be retrievable when a claim or audit comes up. For cargo claims, the carrier's liability runs under Carmack, so the contract should say how claims are filed and who handles them. Put the claim deadline and the contact in writing at the start of the term.
Common lane program problems and fixes
Most lane programs fail slowly, through tenders that get rejected and loads that drift onto the spot market. The first fix is to watch tender acceptance by lane, not just on-time delivery. A lane that looks fine on delivery but routes half its loads to backups is costing more than the award says.
The second problem is a forecast that does not match reality. If you bid five loads a week and ship two, carriers stop planning for you. Update the forecast when volume changes, and write a flex band into the program.
Third is pricing a lane with no carrier behind it. Ask who will run each lane before you award it. Fourth is ignoring the facilities: long detention at a dock makes carriers reject the lane whatever the rate. Fifth is setting fuel and walking away. Agree the surcharge table and review it. Finally, put reviews on the calendar. A full truckload program priced a year ago will drift unless someone checks it against how the lanes ran.
