The moment a moving truck crosses a state line, federal law takes over — specifically the rules set by the Federal Motor Carrier Safety Administration (FMCSA) under the Interstate Commerce Commission Termination Act. That means the mover must be registered with the USDOT, must provide you a written estimate, and must follow specific rules about pickup, delivery, and how much they can charge you on the day of delivery. Knowing this before you sign anything is the single most protective thing you can do.
We've run moving crews on hundreds of interstate jobs over 35+ years. Here's what the rulebook actually says — and where customers most often get caught off guard.
What makes a move "interstate" in the first place?
A move is classified as interstate if it crosses any state line — even if the pickup and destination are geographically close, like moving from Kansas City, MO to Kansas City, KS. It is also interstate if your goods leave the state temporarily (say, for storage) before being delivered within the same state. Intrastate moves (entirely within one state) are regulated by that state's DOT or Public Utilities Commission (PUC), not the federal government.
Why it matters: Interstate movers must hold a USDOT number and an MC (Motor Carrier) number issued by the FMCSA. You can — and should — verify both at the FMCSA's SAFER database (safer.fmcsa.dot.gov) before you book anyone. A mover without those registrations is operating illegally on interstate jobs.
What an interstate mover is legally required to give you
Federal regulation 49 CFR Part 375 spells out the consumer protections that apply to every household goods interstate move. Here's what a registered carrier must provide:
- A written estimate — either binding or non-binding — before any money changes hands for transportation. Verbal estimates are not sufficient.
- "Your Rights and Responsibilities When You Move" — a federal booklet (FMCSA-required) that every carrier must give you before or at the time of the estimate.
- A written order for service confirming the origin, destination, estimated charges, and agreed pickup/delivery dates before loading begins.
- A bill of lading on moving day, which is your legal contract and receipt. You must sign it before the movers begin loading.
- A written inventory of every item loaded and its condition at pickup. Keep your copy — it's your evidence if something is damaged or missing.
If a company skips any of these steps, that's a serious red flag. Our guide on moving scams and how to spot a fraudulent mover covers the patterns we've seen from bad actors who operate without proper FMCSA registration.
Binding vs. non-binding estimates: the interstate version
For interstate moves, this distinction carries real legal weight — more than most customers realize.
| Estimate Type | What It Means | Maximum You Can Be Charged at Delivery |
|---|---|---|
| Binding | Fixed price regardless of actual weight | Exactly the binding amount (no more) |
| Non-binding | Based on estimated weight; final price depends on actual weight | No more than 110% of the original estimate at delivery; balance due within 30 days |
| Binding not-to-exceed | Capped at estimate; can go lower if actual weight is less | The estimate or actual — whichever is lower |
The 110% rule (also called the "110% of non-binding estimate" rule) is a key federal protection: if your mover presents a non-binding estimate, they cannot require you to pay more than 110% of that estimate at the time of delivery. Any amount above that must be billed separately and is due within 30 days. This does NOT apply to charges for additional services you requested after the estimate was written (like a last-minute packing job).
For a deeper look at how these estimate types protect you, see our guide on binding vs. non-binding moving estimates.
How weight — not hours — drives the interstate price
Unlike local moves (which are almost always priced hourly), interstate moves are priced primarily by shipment weight plus mileage. The carrier weighs the loaded truck at a certified scale — called a weigh station or certified scale — and the bill is calculated from that.
You have the right to be present at the weigh-in. You can also request a reweigh if you believe the weight is wrong; the carrier must reweigh at no charge to you before delivery, and the lower of the two weights applies.
Additional cost factors on interstate moves:
- Accessorial charges: Flights of stairs, long carries (typically triggered at 75–150 feet from truck to door), elevator use, shuttle fees if a full-size semi can't access your street
- Packing materials and labor: If the mover packs anything, it's billed separately
- Storage-in-transit (SIT): If delivery is delayed and your goods go into a warehouse, daily storage fees apply — typically $50–$150/day depending on shipment size and market

Pickup and delivery windows: what the law says
One of the biggest surprises on interstate moves is the delivery window — the range of dates within which the mover is contractually obligated to deliver your goods. Interstate carriers routinely consolidate loads, which means your furniture may share a truck with other customers' shipments.
Federal rules require:
- The carrier must provide a written delivery window at the time of the estimate.
- If the mover fails to pick up or deliver within the agreed dates, you may be entitled to compensation — but the specifics depend on the contract language, not a fixed federal formula. Ask explicitly what the late-delivery penalty clause says before you sign.
- Once the carrier notifies you that your shipment has arrived in the destination area, you typically have 24 hours to respond before storage-in-transit charges begin accruing.
We go into full detail on how these windows work in our guide to long-distance moving delivery windows and timelines.
The 5 things to do before your interstate moving truck rolls
- Verify USDOT and MC numbers on the FMCSA SAFER database. Confirm the company's registration is "active" and that their insurance is on file.
- Get your estimate in writing — binding or non-binding — and confirm exactly which services are included. Ambiguity in the estimate is where surprise charges live.
- Read your bill of lading before you sign it on moving day. If anything has changed from your written estimate, ask for a written explanation before you allow loading to begin.
- Walk through the inventory list with the crew lead at pickup. Note any pre-existing damage on the inventory sheet in your own handwriting. Photographs are extra insurance.
- Know your delivery window and plan for the outer end of it. On cross-country moves of 1,500+ miles, a 7–14 day delivery window is common. Have a plan for where you'll sleep and what you'll need in the gap.
You'll also want to think about what your goods are covered for in transit — our guide on what moving insurance actually covers explains the difference between the carrier's basic liability (60 cents per pound per article, federally mandated minimum) and full-value protection.
What happens if something goes wrong?
Interstate carriers are required by law (49 U.S.C. § 14706, the "Carmack Amendment") to accept liability for loss or damage to your shipment. The default level is released value protection — 60 cents per pound per article — which is often woefully inadequate for electronics, antiques, or anything light but expensive. You can upgrade to full-value protection (typically $8–$15 per $1,000 of declared value) before your move.
If you need to file a claim, the carrier must acknowledge it within 30 days and settle or deny it within 120 days. If they don't, you can escalate to the FMCSA or pursue arbitration — registered carriers are required to offer an arbitration program for claims under a certain threshold (typically $10,000).

Frequently asked questions
Does my mover need a USDOT number for an interstate move?
Yes. Any carrier transporting household goods across state lines is required by federal law to hold an active USDOT number and an MC (Motor Carrier) number issued by the FMCSA. You can verify both for free on the FMCSA SAFER database at safer.fmcsa.dot.gov. Never hire an interstate mover that can't provide both numbers.
Can an interstate mover hold my belongings hostage if I don't pay?
A mover can legally hold your shipment if you refuse to pay the lawful charges — this is called a "lien." However, they cannot charge more than the binding estimate, and on a non-binding estimate, they cannot require more than 110% of the estimated charges at delivery. If a mover demands more than is legally allowed before releasing your goods, that is a violation of federal law and should be reported to the FMCSA.
How is an interstate move priced differently from a local move?
Local moves are almost always priced by the hour (labor + truck time). Interstate moves are priced by shipment weight plus mileage, with additional charges for access issues, packing, and storage. You have the right to be present at the weigh-in and to request a free reweigh if you believe the recorded weight is inaccurate.
What is a bill of lading and do I have to sign it?
The bill of lading is the legal contract between you and the mover for an interstate shipment. Federal law requires the carrier to prepare one before loading begins, and you should receive a copy. You do need to sign it — but read it carefully first. If the charges or terms differ from your original written estimate, ask for a written explanation before signing.
How long does an interstate move typically take?
It depends heavily on distance and whether your shipment is part of a consolidated load. Short interstate moves (under 500 miles) may be delivered in 1–3 business days. Cross-country moves (1,500+ miles) typically carry a 7–14 day delivery window. Your written order for service must specify the delivery window, and you should plan for the outer edge of that range.
What's the difference between a "direct" interstate move and a consolidated load?
On a direct move, the truck goes from your origin to your destination with only your goods aboard — faster but more expensive. On a consolidated (or "van line") move, your goods share truck space with other customers' shipments, which is more economical but typically extends the delivery window. Ask your mover explicitly which service they're quoting you on.
