Freight Operations / Shipment size
Less Than Truckload in trucking
Plain-English explanation
Less than truckload (LTL) freight moves in shared trailer space alongside shipments from multiple other shippers, routed through a carrier's hub-and-spoke terminal network. A shipper who needs to move 6 pallets pays for those 6 pallets of trailer space — not a full trailer — and their freight moves alongside other cargo bound in the same general direction. LTL operates through break-bulk terminals. The typical LTL shipment journey: 1. Local pickup driver collects the shipment from the shipper 2. Freight arrives at the origin terminal and is unloaded 3. Terminal workers sort freight onto linehaul trailers by destination region 4. Linehaul driver moves the trailer to the destination terminal (overnight or multi-day) 5. Destination terminal sorts freight onto local delivery routes 6. Local delivery driver delivers to the consignee This means most LTL shipments are handled 4-6 times and touch 2-3 different vehicles. Each transfer adds potential for damage and delay, which is why damage rates are higher in LTL than in FTL. LTL rates use a freight class system (NMFC classes 50-500 based on density, stowability, handling, and liability) combined with weight and distance. The shipper pays based on these factors, not on a flat per-trailer rate.
In a load file, this language usually matters because it changes a rate, appointment, dock instruction, delivery record, or invoice packet.
Why it matters in trucking
LTL is the appropriate shipping mode when a shipper's volume is below the point where FTL becomes cost-competitive. The trade-off is higher per-unit cost and more handling than FTL, offset by the ability to ship smaller quantities without paying for unused trailer space.
The useful details are the ones a dispatcher or billing desk can verify later: who approved the change, when it happened, and which document shows it.
Example in real use
A specialty food manufacturer ships 4 pallets of mixed specialty food products from Portland, OR to Seattle, WA twice per week. The 4-pallet load weighs 3,200 lbs at freight class 65. A local LTL carrier picks up Friday afternoon, linehauls overnight to Seattle terminal, and delivers Monday morning. Total transit: 3 days. FTL for the same load would cost roughly 4x as much because the shipper is not using 80% of the trailer — LTL is the right mode at this volume.
Where it shows up
Less than truckload shows up when smaller shipments share network space instead of taking a full trailer.
What to check first
- Class, weight, dimensions, and packaging.
- Accessorials such as liftgate or appointment.
- Extra handling risk and delivery expectations.
Common mistakes or confusion
- Misclassifying freight to a lower (cheaper) freight class — freight class audits by LTL carriers are common; an incorrect class can result in re-billing at the correct class plus an audit fee.
- Not understanding that LTL transit time is longer and less predictable than FTL — multi-terminal handling adds time and variability; shippers with tight delivery windows should factor this in.
- Overlooking dimensional weight — LTL carriers may charge based on dimensional weight (volume/density) rather than actual weight for light, bulky freight; the freight class captures some of this, but understanding the density calculation prevents billing surprises.
