Less-Than-Truckload (LTL)

Definition

Less-than-truckload (LTL) is a trucking service in which freight from several shippers shares one trailer, each shipper pays for its own portion, and the freight moves through the carrier's terminal network.

In simple English

LTL means your shipment is too small to fill a truck, so it rides with other companies' freight. You pay for the space and weight you use rather than for the whole trailer.

What it means

The FHWA freight glossary describes LTL as a container or trailer loaded with cargo from more than one shipper, made up of loads that do not by themselves meet the truckload requirement.[1] Estes Express Lines, an LTL carrier, describes typical LTL shipments as weighing between 150 and 15,000 lb and occupying only part of a trailer, usually on pallets; its standard pallet is 48 x 40 in.[2]

Where LTL ends is set by each carrier's rules tariff, not by a single regulation. FedEx Freight's 100-Y rules tariff defines LTL as freight weighing less than 20,000 lb and occupying less than one pup, and truckload as 20,000 lb or more or a pup or more.[3] Magnum LTL's tariff sets its line at 19,999 lb or less and under 21 linear feet of trailer.[4]

How LTL freight moves

Estes outlines the flow:[2]

  1. Pickup. The shipper requests a pickup and the carrier collects the freight, along with other customers' shipments on the same route.
  2. Consolidation. Freight from multiple shippers is combined into one trailer.
  3. Linehaul. Short hauls can run directly between service centers; longer ones route through the carrier's hubs.
  4. Delivery. A local truck delivers the shipment, using a liftgate where the consignee has no dock.

Every terminal stop is another handling, so LTL freight should be palletized, wrapped and labeled to survive several forklift moves. That handling is also why LTL is classed and priced differently from full truckload.

How LTL is priced, in brief

Estes names weight, freight class and the lane (its length, volume and competitiveness) as the main price factors, plus accessorial charges and fuel surcharges.[2] Freight class comes from the National Motor Freight Classification, which NMFTA says keeps LTL shipping consistent by assigning commodities a class from 50 to 500 based on density, handling, stowability and liability.[5] The full breakdown is in how LTL freight is priced, and the side-by-side with truckload is in LTL vs. FTL.

Linear foot and cubic capacity rules

Light, bulky freight can fill a trailer without weighing much, so carriers add rules that charge for space. These are tariff rules, and the thresholds differ by carrier. Two published examples:

Space rules in two LTL rules tariffs (check your own carrier's tariff)
TariffLinear foot ruleCubic capacity rule
FedEx Freight 100-YItem 390 (capacity load): freight using a linear length of 15 ft or more, when it is at least 5 ft wide or no identical article fits beside it. Freight over 15,000 lb also counts.Items 613/614: shipments over 750 cubic feet with an average density under 4 lb per cubic foot get a minimum charge based on a calculated weight.
Magnum LTL 125Item 390: a shipment occupying 15 ft of trailer may be charged up to $0.13 per linear foot per actual mile, with a $500 minimum.Item 390: a shipment occupying 750 cubic feet with density under 8 lb per cubic foot is rated on a calculated weight at 8 lb per cubic foot, class 100.

Stacking does not necessarily help. FedEx says linear feet are measured as floor loaded even if the shipment could be stacked, with handling-unit length taken from the side a pallet jack can reach.[3] Magnum treats a shipment as floor loaded when bill of lading instructions or packaging prevent use of the space above it.[4]

Why it matters

A shipment that is quoted as LTL can be billed very differently if it trips a carrier's space rule or is reclassified at a terminal. Measuring pallets accurately, marking stackable freight as stackable on the bill of lading, and recording the true handling-unit count all protect the quote; see why was my LTL shipment reclassified.

Example

Illustrative only: a distributor in New Jersey ships eight pallets, each 48 x 40 x 60 in. and 600 lb, to Georgia. On the trailer floor the pallets sit two across with the 48-in. side running lengthwise, so four rows take 4 x 4 = 16 linear feet. At 16 feet the shipment passes the 15-ft space threshold some carriers use, so the shipper checks the carrier's tariff and asks for a volume quote rather than assuming a standard class-based LTL rate.

Frequently asked questions

What does LTL stand for in trucking?
LTL stands for less-than-truckload. It is freight that does not fill a full trailer, so the carrier combines it with other shippers' freight on the same truck. The FHWA describes an LTL trailer as loaded with cargo from more than one shipper, none of which meets the truckload requirement on its own.[1]
What is LTL freight?
LTL freight is a shipment, usually one or more pallets, that takes up only part of a trailer. Estes describes typical LTL shipments as weighing 150 to 15,000 lb. Carriers combine freight from several shippers, move it through service centers and hubs, and price each shipment by weight, freight class, lane and any accessorial services.[2]
What is an LTL carrier?
An LTL carrier is a trucking company that runs a network of terminals to pick up, consolidate and deliver partial loads from many shippers. Its rules tariff defines what counts as LTL. FedEx Freight, for example, treats freight under 20,000 lb that occupies less than one pup as LTL.[3]
How to calculate linear feet for freight?
Linear feet is the length of trailer floor your freight occupies, measured as if floor loaded. Standard 48 x 40 in. pallets usually sit two across with the 48-in. side lengthwise, so count rows (pallets divided by two, rounded up) and multiply by 4 ft. FedEx measures all freight this way, stackable or not, taking pallet length from the side a pallet jack can reach.[3] [2]
What is the LTL linear foot rule?
It is a carrier tariff rule that charges by trailer space once a shipment occupies a set length. FedEx Freight's capacity load rule applies at 15 linear feet or more under certain width conditions; Magnum LTL's applies at 15 feet and can charge per linear foot per mile.[3] [4] Thresholds vary, so check your carrier's tariff before quoting.
