Get the limit in writing
Any pound figure or packing rule a transporter quotes you is their own company policy, not a federal standard. Ask for it in the same message that confirms the booking, not verbally at pickup.
Vehicles
Can you ship a car with stuff inside it?
Nobody has written a federal rule that answers this cleanly, and that gap is the actual answer. FMCSA licenses two separate kinds of carrier authority, one for vehicles and one for household goods, and a loaded trunk sits in the space between them. What ends up allowed on your specific move is whatever the transporter who books the job decides, in writing, before the truck shows up. Source read 2026-08-19, cited below.

Ask before you load it
Whatever the transporter agrees to in writing is the rule that actually applies to your car.
Two carrier authorities, one gray area
The Federal Motor Carrier Safety Administration licenses vehicle transporters and household-goods movers as different things, and its own registration page, read 2026-08-19, states the line plainly: “Household goods are personal items that will be used in a home.” A carrier authorized to haul cars is not, by that fact alone, authorized to haul household goods. A trunk packed with boxes, clothing and furniture starts to look like the second kind of cargo riding inside the first, which is exactly the ambiguity that has no clean federal answer.
That is not a loophole to exploit; it is the reason the honest answer is “ask the carrier,” not a number pulled from a blog post. Whoever is actually driving your car has their own operating authority, their own insurance terms and their own comfort with the added weight, and only they can tell you what they will accept.
What to nail down before anything is loaded
Confirm what the insurance actually covers
Auto-transport cargo coverage is built around the vehicle. Assume the contents are excluded unless the carrier states otherwise in writing, and consider that anything valuable left inside is riding uninsured until they say so.
Expect a weight ceiling either way
Car haulers load to axle and trailer weight limits set by the equipment and by state and federal highway rules that apply to the truck, not the car. A driver watching those numbers has a real reason to cap what rides inside each vehicle, separate from any household-goods question.
Where these figures come from
- Federal Motor Carrier Safety Administration, Types of Operating Authority — the definition of household goods and the separation between operating-authority types. Read 2026-08-19.
This page states plainly what it did not find: no FMCSA rule, and no page checked for this article, sets a specific weight limit for personal items left inside a vehicle during transport. Any figure claiming otherwise, on this page or elsewhere, is a company's own policy, not a regulation, and it should be confirmed with the specific transporter before you rely on it.
What SMKlog does with a vehicle request
SMKlog's checkout prices United States domestic parcel labels; it does not book a car hauler and never will. Vehicles, loaded or empty, sit alongside pallets, LTL, full truckload and other freight as request types our freight review form is built to take. Describe the vehicle, both addresses, and honestly, what is staying inside it, and a person tells you what is possible and what the actual transporter will require.
Common questions
Can you ship a car with stuff inside it?
There is no federal law that answers this either way. FMCSA regulates auto-hauler carriers and household-goods carriers as two different kinds of authority, and leaving personal belongings in a vehicle sits in the gap between them. Whether a specific truck will take a loaded car, and how much they will allow, is a decision the carrier makes when they book the job, not a rule printed anywhere.
Why does it matter which kind of carrier is hauling the car?
Because FMCSA defines household goods as personal items that will be used in a home, and a carrier authorized to transport vehicles is not automatically authorized to transport household goods. A trailer loaded with boxes and furniture inside the cars it is hauling starts to look like the second kind of move riding along inside the first.
Is there a standard weight limit for items left in the car?
No published federal one. Any specific pound figure quoted online is a given company's own policy, not a regulation, and it is not something SMKlog can confirm on your behalf since we do not book vehicle transport ourselves. Ask the transporter directly and get the answer in writing before the pickup.
Does the transporter's cargo insurance cover the stuff inside?
Assume no until told otherwise in writing. Auto-transport cargo coverage is built around the vehicle itself, and belongings left inside it are the kind of thing that gets excluded in the fine print. Confirm coverage for the contents specifically, not just the car, before anything is loaded.
Does SMKlog quote vehicle shipments with items inside?
Not through the checkout. SMKlog's calculator prices United States domestic parcel labels; a vehicle, loaded or empty, goes through freight review, where a person reads the details, including anything left inside, and answers with what is possible.
