LTL Trucking: The Complete Guide to LTL Transportation

Key Takeaways

• LTL trucking puts several shippers' freight on one trailer to cut cost.
• Freight class, NMFC codes, weight, and distance drive LTL rates.
• The right LTL carrier balances coverage, pricing, and reliability.
• Partial truckload skips terminals for loads too big for cheap LTL.

LTL trucking, or less-than-truckload transportation, is a shipping method where multiple shipments share space in a single trailer. It gives businesses a cost-effective option for pallet-sized freight that's too large for parcel but doesn't need a full truckload.

Full truckload (FTL) trucking mostly serves high-volume shippers and large organizations. LTL trucking is one of the most widely used freight transportation methods, suited to companies that ship smaller loads and need a cost-effective balance between flexibility and speed.

Understanding how LTL works, and where it fits alongside other freight modes, helps businesses reduce costs, avoid reclassification fees, and choose the right carriers for each lane. This guide covers the main characteristics of LTL trucking, what drives its cost, how to choose the right LTL carrier, and how LTL differs from partial truckload.

What Is LTL Trucking, and When Does It Make Sense to Use It?

LTL trucking is a freight transportation method for shipments that don't need a full truckload. LTL carriers consolidate freight from multiple organizations onto one trailer, so businesses can move smaller volumes at a fraction of the cost of FTL shipping. It makes the most sense for palletized cargo, recurring shipments, and orders that don't meet FTL size requirements.

LTL also works well alongside full truckload for shippers with mixed volume: high-priority freight moves FTL, while lower-priority, smaller-volume freight moves LTL. For a closer look at how LTL, partial truckload, and FTL compare by pallet count and weight, see our guide to LTL shipping.

How Does LTL Trucking Differ from Other Freight Modes?

LTL differs from FTL and parcel because it pairs smaller shipment sizes with freight-specific handling. LTL freight moves through a hub-and-spoke network of terminals, while FTL trucking offers direct end-to-end transportation.

Compared to parcel, LTL accommodates heavier and bulkier freight that requires forklift handling. That makes LTL the middle ground between parcel and full truckload, carrying heavier freight than parcel while staying more flexible and cost-effective than a dedicated truck.

What Equipment Do LTL Carriers Use?

LTL carriers use equipment matched to different shipment sizes and delivery requirements. Knowing which equipment a shipment needs helps shippers avoid extra accessorial charges and get their freight handled properly.

• Trailers: Standard dry van pup trailers, often paired into doubles, make up the backbone of LTL linehaul and allow flexible routing through dense terminal networks.
• Liftgates: Hydraulic platforms mounted on the back of a truck, essential for deliveries to locations without loading docks.
• Specialized trucks: Temperature-controlled reefers, flatbeds, and hazmat-certified trailers expand what LTL networks can carry for industry-specific needs.

What Factors Affect LTL Freight Rates the Most?

Freight class, weight, distance, and accessorial requirements shape LTL pricing the most. The LTL industry is also far more consolidated than the full truckload market. A handful of national carriers control a large share of network capacity, while hundreds of regional specialists serve high-density lanes, which is part of why rates can vary so much from lane to lane.

How Do Freight Class and NMFC Codes Affect LTL Pricing?

Freight class, set using NMFC codes, is based on density, handling, and liability, and it's one of the biggest levers in an LTL quote. Misclassified freight is a common source of after-the-fact reclassification fees. Our guide to LTL freight rates breaks down how to avoid the most common pricing surprises.

How Do I Reduce LTL Freight Costs Without Switching Carriers?

Shippers can lower LTL costs without switching carriers by tightening freight class accuracy, consolidating shipments where possible, and benchmarking rates across their existing carriers instead of defaulting to habit. A transportation management system centralizes that comparison, so cost differences across carriers and lanes are visible before you book.

How Do I Choose the Right LTL Carrier for Time-Sensitive Shipments?

Choosing an LTL carrier for time-sensitive freight means evaluating coverage, pricing, transit times, and freight handling performance, along with the carrier's technology and integration capabilities. The right carrier improves visibility and reliability and lowers the chance of freight damage. Our breakdown of LTL carrier selection has a more detailed checklist.

Major national carriers like FedEx Freight, Old Dominion, Saia, and XPO hold a large share of network capacity, while regional carriers often win on lane-specific service and transit time. Rising e-commerce volumes and more frequent inventory replenishment keep LTL demand up, and LTL freight technology, including API-driven visibility tools and TMS integrations, is changing how carriers and shippers manage pricing and transit times.

What's the Difference Between LTL and Partial Truckload Shipping?

LTL and partial truckload (PTL) both sit below a full truckload, but they work differently. LTL moves through a hub-and-spoke network of terminals and is priced by freight class, while PTL skips the terminal network for a more direct move and is typically priced by weight and space instead of classification. PTL tends to fit shipments too large for economical LTL but not large enough to justify a full trailer.

Once you've settled on a mode, the next step is pricing the shipment accurately. See how to get an LTL freight quote for the details carriers need from you.

Frequently Asked Questions

What Does LTL Trucking Mean?

LTL trucking means less-than-truckload transportation, where a carrier combines freight from several shippers on one trailer and each shipper pays for the space and weight it uses. It's built for pallet-sized freight that's too large for parcel but too small to justify a full truckload.

How Do I Get Accurate LTL Freight Quotes for My Shipments?

Accurate LTL quotes start with correct freight class, precise weight and dimensions, and full accessorial requirements up front. Rating across multiple carriers at once, rather than requesting quotes one at a time, also surfaces pricing differences that are easy to miss otherwise.

What Accessorial Charges Apply to LTL Trucking?

Common LTL accessorials include liftgate service, inside delivery, residential or limited access delivery, appointment scheduling, and reweigh or reclassification fees. Listing every service you need on the quote request and the bill of lading keeps those charges from showing up as surprises on the invoice.
