Knowledge check and completion (not a certification) ## 01. How to use this guide Less-than-truckload (LTL) is one of the most cost-effective ways to move palletized freight in the United States. It is also one of the most misunderstood. The shippers who have the smoothest experience are not the ones who fight the system; they are the ones who understand how it works and set the right expectations with their own customers about pickups, transit, and delivery. This document explains the rules of the road as the LTL industry actually operates them. Read it once end-to-end, then keep it as a reference. The sections you will return to most are freight class (Section 7), accessorials (Section 8), transit times (Section 10), volume limits (Section 11), and claims (Section 16). **The single most important idea.** LTL is a mature, highly engineered, shared-network industry. Its processes were built over a century to keep thousands of trucks and millions of shipments moving every day. It will not change those processes for any individual shipment. Not for Mothership, and not for any broker or platform. Working with the system gets your freight delivered. Working against it gets it delayed.
## 02. How the LTL network physically works In full truckload (FTL) shipping, one truck is loaded at the shipper's dock and drives straight to the destination. LTL is the opposite: your handful of pallets shares a trailer with dozens of other shippers' freight, and it travels through a network of terminals rather than going door-to-door. Understanding that network explains nearly every rule, fee, and timing question that follows. ### The hub-and-spoke flow On a long lane, freight is re-sorted at one or more intermediate sorting terminals (breakbulk). A typical long lane is three nights from origin to destination, never straight door to door. 1. **Local pickup.** A city driver collects your freight along with everyone else's in the area and brings it to the origin service center (terminal). 2. **Cross-dock and sort.** At the terminal your pallets are unloaded, weighed, measured, sorted by destination, and re-loaded onto a line-haul trailer headed the right direction. 3. **Line haul.** Long-distance trailers, typically 48 ft or 53 ft vans, often run as doubles in many lanes, move freight terminal-to-terminal, usually overnight. 4. **Relay / intermediate sorting terminals (breakbulk).** Longer lanes pass through one or more intermediate sorting terminals, where freight is unloaded and re-sorted again, often adding a night per stop. 5. **Destination terminal and delivery.** At the final terminal your freight is loaded onto a local delivery truck for the last mile. The benefit of this design is enormous: by consolidating many small shipments, carriers achieve scale that makes shipping a few pallets affordable. The trade-offs are equally built-in: your freight is handled 4-6 times, it moves on a fixed network schedule rather than on demand, and it cannot deviate from that schedule for a single shipment. **Why this matters.** Every time freight is touched there is a chance of damage, and every terminal stop is a scheduled, sequenced event. This is why LTL costs less than FTL, why transit is measured in business days, and why a cross-dock has almost no room to store your freight. ## 03. When to ship LTL, and when not to LTL is the right tool for a specific job. Using it for the wrong job is the most common (and most expensive) mistake shippers make. **A perfect fit when** you are moving roughly 1-6 palletized handling units, the shipment weighs between about 150 and 10,000 lbs, your freight is sturdy and well-packaged, and you can live with delivery measured in business days rather than hours. **Use another mode when** you have more than about 10 pallets, more than about 12 linear feet, or over about 10,000 lbs (use FTL); you need a same-day or guaranteed-hour arrival (use local same-day or expedited); or the freight is fragile, high-value, or will not survive 4-6 handlings. For local metro moves where speed and real-time visibility matter, Mothership's Local Same-Day service keeps freight on one truck with no terminal stops. For shipments that outgrow standard LTL, the right mode is FTL. The shippers with the best LTL experience are not the ones with the most leverage. They are the ones who tell their customers up front how LTL works and what to expect.
## 04. The top 25 U.S. LTL carriers by revenue The U.S. LTL market is highly concentrated: the top 25 carriers account for roughly 91% of a ~$53-billion market. Revenue: SJ Consulting / Logistics Management, 2024, including fuel surcharge. This is the U.S. market landscape ranked by revenue, not Mothership's carrier roster.

The largest carrier overall is not necessarily the right (or even an available) carrier for your specific origin, destination, and freight.
## 05. Direct versus interline carriers Not all coverage is created equal. The biggest predictor of pickup reliability, tracking accuracy and document speed is whether the carrier runs your shipment on its own assets the whole way. **Direct carriers** service the shipment entirely (or almost entirely) on their own drivers, trucks and terminals. Choose direct when transit time and visibility matter most. **Interline carriers** hand the shipment off to third-party drivers, trucks and terminals for part of the route. Choose interline when price is the priority. There is no universally better answer, only the right answer for a given shipment. Mothership surfaces both so you can weigh speed and visibility against cost on every lane.
## 06. Liftgates, pallets and equipment limits ### Liftgate capacity A hydraulic tailgate (liftgate) is the platform on the back of a truck that raises and lowers freight when there is no loading dock or forklift. Limits are physical, not negotiable. - Typical max weight per liftgate cycle: ~2,500 lbs (range about 1,300-3,500 lbs) - Typical platform width: 80-89 in (standard 48 in x 40 in pallet) - Typical platform depth: 30-70 in If a single handling unit exceeds roughly 2,500 lbs or about 96 in in length, it likely will not clear a liftgate. Split it, use a dock/forklift, or plan a terminal pickup. ### When can you use a liftgate? | If this is true at the stop | Liftgate? | What to do | |---|---|---| | No loading dock and no forklift on site | Required | Add a liftgate at booking. | | Residential or curbside delivery | Required | Liftgate (usually with a residential fee) almost always applies. | | Each pallet is at or under ~2,500 lbs and fits the platform | Works | A standard liftgate handles it. | | A loading dock is available | Not needed | Skip it: freight rolls off at the dock. | | A forklift is available on site | Not needed | Skip it: the forklift loads and unloads. | | A single piece is over ~2,500 lbs or longer than the platform | Will not fit | Use a dock or forklift, split the load, or arrange a terminal pickup/delivery. | ### Pallet weight and dimensions When a liftgate is not needed, pallets can be heavier. Most LTL carriers accept individual handling units up to roughly 4,000-10,000+ lbs depending on tariff. - Standard pallet footprint: 48 in x 40 in. Keep freight within the footprint. - With a liftgate: keep each pallet at or under ~2,500 lbs. - Without a liftgate: any single piece over 8 ft (96 in) triggers an over-length charge; past 12 ft climbs steeply. - Cap pallet height so a non-stackable load is not rated as if it fills full trailer height (a 48 in non-stackable pallet is often treated as 96 in tall for cubing).
## 07. Density, freight class and the 2025 NMFC changes Every LTL shipment is assigned a freight class (50 to 500) and one or more NMFC item codes (NMFTA). Lower class numbers cost less. Historically class balanced density, handling, stowability and liability. Carriers now expect an NMFC number on every commodity on the BOL. A missing or incorrect NMFC is a common rebill trigger. Mothership is rolling out AI-powered NMFC lookup in the cargo-description field. Effective July 19, 2025 (NMFTA Docket 2025-1), roughly 2,000 commodities shifted to density-based classification and the density scale went from 11 tiers to 13. Docket 2026-1 begins rolling out in early 2026. Density is weight divided by cubic feet. At booking, declared dimensions and weight produce a quoted class. After pickup the carrier measures the freight (Section 14). If actuals differ, the bill changes. A wrong description or missed dimension is the number one cause of reclassification. Write descriptions that prevent reclassifications: name the actual commodity, give packaged dimensions and weight including overhang, state stackability accurately, and include NMFC/class on the BOL when known.
## 08. Extra freight services (accessorials) explained Accessorials are priced services beyond dock-to-dock pickup and delivery. Declare every one you will need at booking. If a driver arrives without the right equipment, you get a failed attempt, a redelivery fee, and a delay. | Accessorial | What it is | When you need it | |---|---|---| | Liftgate | Platform to raise/lower freight without a dock. | No dock or forklift; most residential moves. | | Residential | Surcharge for a home or home-based business. | Address zoned or used as residential. | | Limited access | Smaller vehicle and/or fee outside a commercial zone. | Schools, churches, farms, military, storage, construction, no dock. | | Inside delivery | Past the first doorway. Not white-glove. | Freight must go inside the entrance. | | Delivery appointment | Carrier sets a time. They do not accept pre-made ones. | Customer requires a scheduled time. | | Call before delivery | Advance notice, not a set appointment. | Heads-up without a set time. | | Over-length | Surcharge for long pieces. | Over ~8 ft (96 in); steeper over 12 ft. | | Reconsignment / diversion | Address change after dispatch, or a return. | Address changes in transit, or freight refused. | | Wait-time fee (detention) | Holding the driver past free wait time. | Freight not ready, or loading runs long. | | Sort and segregate | Separate by piece, item number, or PO. | Customer requires freight broken out. | | Tradeshow / convention | Event venue pickup or delivery. | Often with limited access, appointment, liftgate. |
The cheapest accessorial is the one you declared up front. Charges added after the fact almost always cost more and come with a delay. Appointments are delivery-only, and the carrier sets them. Call before delivery is advance notice, not a scheduled time. There are no pickup appointments. LTL carriers will not accept a pre-made appointment you arrange on the receiver's behalf. Amazon and other appointment-only docks: the carrier or broker books the slot (Amazon Carrier Central, using PO/ASN/ARN and pallet count). Amazon issues an ISA ID. Miss the window and freight is turned away. Do not promise a delivery date until the appointment is confirmed. You cannot approve accessorials at delivery in LTL. The driver cannot hold the truck. If an accessorial is needed, the carrier performs it on the spot. Withholding approval leads to detention, a failed delivery, or storage that costs more than the accessorial. Quotes are ZIP-to-ZIP. Street-level realities (road weight limits, a smaller truck, no liftgate, trees, steep roads, a dirt driveway) can still change the price. Tell us everything you know about the site up front.
## 09. Pickup and delivery windows LTL drivers deliver in the morning and pick up in the afternoon. A driver leaves the terminal full, empties the truck on deliveries, then collects new freight on the way back. Tight late-morning pickup windows are hard to honor. - Pickups: typically afternoon. Request by an early-afternoon cutoff. Minimum ~2-hour ready window; block out 4 hours. - Deliveries: business hours, weighted toward the morning. - Line haul runs overnight. Pickup/delivery is Monday-Friday. Weekends are not service days. If freight is not ready at pickup, the driver usually cannot wait. That is a missed pickup plus a failed-attempt fee. If no one can receive at delivery, freight returns to the terminal with a redelivery fee and possible storage (Section 13). Always ship on the Mothership Bill of Lading. If the shipper uses their own BOL, tracking can fail and the carrier may not honor the quoted rate. ## 10. Transit times are estimates, not promises Standard LTL transit is in business days, not guaranteed arrival times. Pickup day does not count. Weekends and holidays are not transit days. A 3-day estimate quoted Thursday typically delivers the following Tuesday. Rural lanes add time. Guaranteed delivery service commits to the delivery date, not the pickup. A late pickup typically slides the guarantee one business day. Some delivery accessorials can void a guaranteed quote. Scenario A: picked up Monday, 2-day estimate delivers Wednesday. Scenario B: picked up Thursday, 3-day estimate delivers Tuesday (weekend does not count). Once freight is in the network it moves on the next scheduled line haul. Calling cannot conjure an extra trailer departure.
## 11. Shipment size and capacity limits When a shipment dominates trailer space, carriers switch to volume / linear-foot / cubic-capacity pricing. - ~12 linear ft: common limit before linear-foot rules apply - 6+ pallets: where standard LTL pricing starts to climb - ~750 cubic feet: cubic-capacity trigger when density is under ~6 lb/cu ft Split-shipment rule: do not tender same origin-destination, same carrier, same day, if together it crosses the volume threshold. Carriers combine same-lane same-day shipments and re-rate at volume pricing. Split across two carriers, or send the second only after the first is in transit. Mothership quotes standard LTL up to 10 standard pallets. We do not quote volume or partial-load LTL. Larger freight is FTL. ## 12. Free wait time and wait-time fee (detention) Free wait time is short (often 15 to 30 minutes). Past free time, carriers charge detention (per 15 minutes or hourly). Often the driver cannot wait at all: if freight is not ready they leave, and you get a missed-pickup or redelivery fee instead. Stage freight before the window opens. ## 13. Free storage and why cross-docks charge Free storage is commonly a day or two. A cross-dock is not a warehouse. Stored freight occupies dock floor and gets extra handling. Storage accrues when the customer cannot accept, an appointment cannot be scheduled, or paperwork holds the freight.
## 14. Certified scales, dimensionalizers and rebills Carriers re-weigh and re-measure on certified scales and dimensionalizers. That certificate is legal proof. Recurring rebills almost always start at the warehouse at packing time. Disagreeing with a certified measurement does not win. Prevent it by precise weighing and measuring before freight ships. ## 15. Rebill disputes and timelines Mothership gives you 10 days to review and dispute a rebill before payment. Most other platforms bill first. Winning requires evidence that contradicts the certified measurement (your scale ticket and documented packaged dimensions). If you win after payment, the amount is refunded.
## 16. Liability limits and freight claims Carrier liability is Carmack Amendment released value, not full-value insurance (often $/lb). FreightProtect closes the gap when cargo value exceeds that. Inspect and note at delivery before signing. File BOL, POD, invoice, photos, itemized loss. Pay freight charges. Keep damaged freight. File within 9 months; concealed damage within 5 business days. ## 17. How LTL tracking really works Not real-time GPS. Scan-by-scan status, typically once or twice a day. Mothership shows the same information the carrier's customer service has. ## 18. Why you cannot contact the carrier directly LTL networks do not permit drivers to contact or be contacted by shippers. Mothership is the single point of coordination.
## 19. Why no platform or broker controls the LTL carriers No broker has more operational control over an LTL carrier than another. Missed pickups are caused on the road, not in software. Mothership cannot override physics. What we can do is prevent a share of failures with integrations, classification, accessorial detection, and monitoring. ## 20. Reconsignments and diversions A reconsignment is an address change after freight is moving. The carrier locates and holds it, re-rates the new lane, and re-routes it. The transit clock effectively restarts. Confirm the final address before you book. ## 21. Receiver contact information Give a name, phone, and email for someone who can authorize delivery. Missing contact is a common delay. Freight sits and storage accrues (Section 13).
## 22. Hazardous materials (hazmat) Provide at booking: proper shipping name, UN/NA number, hazard class/division, packing group; hazmat-compliant BOL with a 24-hour emergency phone; labels, markings, placards, 49 CFR packaging; current SDS. Declare hazmat up front. Never ship undeclared. Restricted (not classic hazmat): alcohol is not accepted by every carrier in all 48 states; many carriers blacklist nicotine, vapes, and tobacco. Limit your quote to carriers that accept the commodity. ## 23. Trade-show and convention deliveries Advance warehouse (safer for LTL): ship early, often up to ~30 days ahead. Direct to show site: narrow target date/time, marshalling yard. Miss the window and freight is refused. Drayage is billed by weight. Target dates are rarely negotiable. ## 24. Why shipping through Mothership wins Aggregation: pooled volume buys deeper discounts and better accountability than going direct, without long-term contracts.
## 25. The expectation-setting checklist The best LTL outcomes come from preparation and from telling your customers what to expect. Run this list before you book, and share the relevant parts with your customer (the person receiving the freight). - Measure and weigh precisely after palletizing and wrapping (including overhang) to prevent reclassifications and rebills. - Describe the commodity accurately and note stackability; let the platform handle class/NMFC. - Declare every accessorial up front: liftgate, residential, limited access, inside delivery, delivery appointment, call-before. - Confirm the final delivery address before booking. Mid-transit reconsignments are slow and costly (Section 20). - Give complete receiver contact info (name, phone, email) so the terminal can schedule and deliver (Section 21). - Ship on the Mothership BOL so tracking flows back to you and the quoted rate is honored. - Declare hazmat fully: UN number, class, packing group, SDS and emergency contact (Section 22). - Confirm dock/forklift availability at both ends; add a liftgate if either lacks one. - Keep shipments within standard LTL: up to 10 pallets (and roughly 12 linear ft / 750 cubic feet); split same-lane, same-day hand-overs (tenders) so they do not combine and re-rate. Larger freight moves as FTL. - Stage freight before the pickup window opens; request pickups early with a wide window. - Set transit expectations in business days. Pickup day does not count, weekends are not transit days; choose guaranteed service when a date is critical. - Expect scan-by-scan status updates, updated once or twice a day. The platform shows the same data the carrier has. - Inspect and note at delivery before signing; keep the Bill of Lading, proof of delivery, invoice and photos for any claim. - Consider FreightProtect whenever cargo value exceeds standard carrier liability. Set the expectations properly with your customer upfront, prepare the freight, and let the network do what it is engineered to do. That is how you win at LTL. ## Knowledge check and completion This is a knowledge check, not a certification.
