Most carriers allow it. None of them insure it. That gap matters more than you think.#

Yes, you can usually ship a car with personal items inside. The practical answer is that most auto transport carriers allow up to 100 pounds of personal belongings stored in the trunk below the window line. That allowance is real, it's common, and plenty of people use it without incident.

The part that gets people into trouble is what happens to those items under the carrier's insurance. The answer is nothing—carrier cargo insurance covers the vehicle, not its contents. Personal items in a shipped car travel at your complete risk, with zero coverage from any insurance involved in the transport transaction.

Understanding exactly what's allowed, what's prohibited, why certain items cause serious problems, and how to think about the risk is what makes this a smart decision rather than an expensive surprise.

What most carriers actually allow#

The standard policy across most major auto transport carriers: personal items are permitted in the trunk, below the window line, up to approximately 100 pounds total. That's the common baseline. Specific carriers vary:

Some carriers prohibit personal items entirely and enforce this strictly at pickup. Others allow up to 100 pounds in the trunk with no questions. A handful allow items in the back seat or floor areas as well, not just the trunk. A small number allow more than 100 pounds by arrangement—though this typically triggers additional fees.

The only way to know your specific carrier's policy is to ask directly when booking. Don't assume. If you're planning to use the trunk allowance, confirm it's permitted before pickup day, not when the driver is standing there with your car on the ramp.

The below-the-window-line requirement isn't arbitrary. Carriers need to maintain visibility for inspection, securing, and safety checks throughout transit. Items stacked above the window line block sightlines, affect load balance on the trailer, and can shift during transport. Items in the front seat, on the dashboard, or anywhere that could interfere with driving the vehicle onto and off the carrier are not permitted.

What you absolutely cannot put in a shipped vehicle#

Some items are prohibited regardless of carrier policy—either because they create safety hazards during transport, create legal liability crossing state lines, or are flat-out illegal to transport in a commercial carrier context.

Hazardous materials. This is the non-negotiable category. Anything flammable, explosive, corrosive, or toxic cannot be in a shipped vehicle. Specifically:

• Gasoline, propane tanks, butane canisters—any fuel
• Fireworks, ammunition, flares
• Pesticides, herbicides, fertilizers with flammable components
• Cleaning chemicals in large quantities
• Lithium batteries not installed in devices (loose, uninstalled lithium batteries are regulated hazardous materials)
• Any compressed gas canister

Carriers are transporting eight to ten vehicles on an open trailer across potentially thousands of miles. A fuel leak, a pressurized canister failure, or an ignition source in an enclosed space represents a catastrophic risk—to your car, to other owners' vehicles, to the driver, and to other motorists. Federal DOT hazardous materials regulations apply to commercial transport, and violations carry significant penalties.

If a driver discovers prohibited hazardous materials at pickup, they can refuse the load. If discovered mid-transport, they're required to report it. The consequences fall on you.

Firearms and weapons. Federal law governing interstate transport of firearms is complex, and commercial auto transport creates specific complications. Most carriers prohibit firearms in shipped vehicles entirely because the legal requirements for interstate firearm transport—proper storage, licensing, state-by-state compliance—create liability they're not equipped to manage. If you need to transport firearms during a move, consult a firearms attorney for the legally correct method. Auto transport is not it.

Irreplaceable personal documents. Not prohibited by carriers, but genuinely foolish to ship. Passports, birth certificates, Social Security cards, vehicle titles, financial account documents—these travel with you personally. If the vehicle is in transit for 10 days and you need your passport for any reason, you don't have it. If something happens to the vehicle, these documents are gone with no recourse.

Prescription medications. Similar logic. Controlled substances crossing state lines in a vehicle with no accompanying driver creates ambiguous legal situations, and medications you need daily shouldn't be inaccessible for the duration of transit. Carry medications with you.

Valuables that can't be replaced. Jewelry, cash, heirlooms, electronics, musical instruments, collectibles—anything where loss would cause genuine financial or emotional harm. These are not insured. They are not the carrier's responsibility. They should not be in the shipped vehicle.

Food and perishables. Obvious once stated but worth saying: a car in transit sits in the sun on an open carrier for days. Food spoils, creates odors, and attracts pests. Even non-perishable food can become an animal attraction if the vehicle is in outdoor storage. Leave food out entirely.

Plants. Many states have agricultural inspection requirements at their borders. Live plants are potential vectors for invasive species, insects, and plant diseases. Some states prohibit bringing certain plants across their borders. Auto transport carriers don't manage this compliance for you, and an agricultural inspection that finds regulated plants can delay your vehicle and create fines.

Why the 100-pound limit exists and what happens if you exceed it#

The weight limit isn't arbitrary courtesy—it reflects how carriers manage payload and legal weight limits.

An open transport carrier hauling eight to ten vehicles is already operating near its permitted gross vehicle weight. Every vehicle has its own weight, and personal items inside each vehicle add to that total. Federal and state highway regulations set maximum gross weights for commercial vehicles. Exceeding those limits exposes the carrier to fines at weigh stations, inspection failures, and potential permit violations.

Practically: carriers load vehicles and drive them through weigh stations. The total weight matters. Extra weight beyond the allowance in multiple vehicles can push a load over permitted limits. This is why carriers are serious about the policy and why drivers check at pickup.

Beyond the regulatory issue, excess weight affects how a vehicle sits on the carrier's trailer—which affects securing equipment, load balance, and fuel economy. A trunk loaded with 300 pounds of books changes the vehicle's weight distribution in ways that affect all of these.

If you exceed the weight limit and the driver discovers it at pickup, you'll be asked to remove items until you're within limits. Plan for where those items go before pickup day, not during it.

The insurance gap: what "not covered" actually means in practice#

This point deserves more than a passing mention because the financial exposure surprises people.

Carrier cargo insurance—the minimum $100,000 coverage required by federal law—covers the vehicle. It's structured around vehicle damage: a ding during loading, paint damage from road debris, impact from an accident. The insurance policy covers the vehicle as the cargo. Personal belongings inside the vehicle are not cargo under the policy definition; they are incidental contents.

Your personal auto insurance doesn't typically cover personal property inside a vehicle during commercial transport either. Your auto policy covers the vehicle (when you or an authorized driver is operating it, or sometimes when it's parked and broken into). Cargo inside a vehicle in commercial transit is generally excluded.

Homeowners or renters insurance might cover personal property during a move—some policies extend to belongings "temporarily away from home" including during transit. The operative word is might. Coverage, deductibles, and exclusions vary significantly by policy and carrier. Before assuming your homeowners policy covers items in a shipped vehicle, call your insurer and ask specifically. Get the confirmation in writing. Don't assume.

If the answer is "no, your homeowners policy doesn't cover items in a commercially shipped vehicle," you now have a clear picture: those items have zero insurance coverage for the duration of transport.

What actually happens to personal items during transport#

Understanding the physical reality of auto transport helps calibrate the risk.

Your vehicle is loaded onto an open carrier with seven to nine other vehicles. It travels—typically over 7–14 days on a coast-to-coast route—through highway driving, weather, vibration, temperature fluctuations, and multiple stops for pickups and deliveries. Other vehicles load and unload around it. The driver may need to reposition your vehicle on the trailer at various points.

Trunk items shift during transit. A poorly packed trunk that's fine for a weekend road trip is not the same as a packed trunk subjected to 10 days of highway vibration. Fragile items that aren't properly packed and cushioned will move and potentially break. Heavy items that shift can damage the trunk lining or other items.

On an open carrier, your vehicle is also exposed to weather. Rain, dust, and road debris affect the exterior. They don't typically penetrate a closed trunk—but temperature swings are real. A trunk in July in the Arizona desert on an open carrier gets hot. Items that are heat-sensitive (candles, cosmetics, some medications, electronics) shouldn't be in a trunk that will sit in 115°F ambient temperatures for multiple days.

The vehicle sits at various terminal points or in the carrier's lot during transit. It's not under surveillance. Items visible through windows attract theft risk—which is one of many reasons the below-window-line requirement exists.

Smart packing if you're using the trunk allowance#

If you've confirmed your carrier allows personal items and you're going to use the allowance, pack intelligently:

Weight distribution matters. Concentrate heavy items low and centered in the trunk. Off-center loading changes vehicle weight distribution. A 100-pound load distributed evenly across the trunk floor is better than 100 pounds stacked to one side.

Pack items in boxes or hard containers, not loose. Loose items shift freely and are more likely to damage each other or the trunk lining. Boxes create structure and limit movement. Hard-sided containers (plastic totes with lids) are better than cardboard for items that need protection.

Cushion fragile items properly. Transport involves sustained vibration over extended distances. Wrapping fragile items in bubble wrap or clothing and surrounding them with soft material helps. But honestly, if it's truly fragile and truly valuable, it shouldn't be in the trunk.

Don't exceed the trunk by one item. The 100-pound limit is a ceiling, not a target. Packing to exactly the limit leaves no margin if the driver's estimate differs from yours. Keep it meaningfully under the limit.

Don't put anything in the cabin. Items on seats, floors, or the dashboard are prohibited by most carriers because they interfere with driving the vehicle. They're also visible, which creates theft risk and complicates any interior condition documentation.

Photograph the packed trunk before pickup. This documents that you complied with weight and placement requirements and provides a reference if any trunk contents are later questioned.

The practical decision framework#

Here's how to think about what goes in the trunk:

Ship in the trunk: Non-valuable, non-fragile items that would be inconvenient to ship separately but aren't worth insuring. Extra clothing, bedding, household linens, non-fragile kitchenware. Items where loss or damage would be disappointing but not financially significant. Items that fit comfortably under the weight limit.

Don't ship in the trunk: Anything you'd be genuinely upset to lose. Anything fragile. Anything heat-sensitive. Anything valuable. Anything you'll need during the transit period. Anything prohibited by your carrier or by law.

Ship separately: High-value personal property that needs to move with you belongs in a properly insured shipment—either with your household goods through a licensed mover (which covers personal property), or carried with you personally.

The trunk allowance is a convenience feature, not a moving solution. It's useful for offloading a specific category of items—the "this is annoying to pack separately" category—but it shouldn't be the plan for anything that actually matters.

What to do if items are damaged or missing at delivery#

If you arrive at delivery and items in the trunk are damaged or missing, the process is limited by the insurance reality described above.

First, document immediately. Photograph the trunk and any damaged or missing items before the driver leaves and before you move anything. Note the condition on the delivery Bill of Lading—though carriers will typically add a notation that personal items are not their responsibility.

Second, file a claim with your homeowners or renters insurance if you confirmed coverage before shipping. This is why the pre-shipment call to your insurer matters—you should know before shipping whether this path exists.

Third, contact the carrier in writing. Even though carriers are not legally obligated to compensate for personal items under cargo insurance, some will offer goodwill compensation for damaged belongings as a customer service measure. This is entirely at their discretion and not contractually guaranteed.

Fourth, for theft specifically, file a police report. If items were clearly stolen from the trunk during transit, a police report creates a record and may support an insurance claim.

The honest reality: recovery options for damaged or missing personal items in a shipped vehicle are limited. This is the argument for keeping truly valuable items out of the trunk—not because the risk is inevitable, but because the recovery path is narrow when something does go wrong.

Final thoughts#

Shipping a car with personal items inside is permitted by most carriers, useful for the right category of items, and genuinely risky for the wrong ones. The 100-pound trunk allowance gives you a place to put the "annoying to move separately" category of household items. It does not give you insured coverage, temperature protection, vibration protection, or theft protection.

Know your carrier's specific policy before pickup. Confirm it in writing when you book. Stay within the weight limit. Pack for vibration, not for a weekend drive. Don't put anything in the trunk you'd be genuinely upset to lose—and don't put anything prohibited in there at all.

The items that matter should either travel with you or ship separately through an insured channel. Everything else can fill the trunk.
