How to Prepare Your Car for Auto Transport

Published Read 8 min read

The day the carrier shows up is not the moment to start thinking about whether your fuel tank is too full or where you left the second key. By then the driver is on a tight route, your car is one of several being loaded, and anything you forgot becomes a problem you carry to the other end. A little prep in the days before pickup makes the handoff faster, protects you if a dispute comes up later, and keeps your car from arriving with a surprise no one can explain. This guide covers exactly what to do to a vehicle before a carrier loads it.

This is the prep step only. Choosing and booking a carrier, what the whole thing costs, the choice between open and enclosed trailers, and shipping a motorcycle each have their own guide (see our guides on booking auto transport, transport costs, open vs. enclosed transport, and motorcycle shipping). Here we assume you already have a carrier scheduled and a pickup window, and you just need the car ready.

Why Prep Matters Before the Carrier Arrives

Auto transport across state lines is treated as freight, and the legal backbone of the job is a document called the bill of lading. Under federal household-goods rules, the bill of lading is both your receipt and the contract for the move, and the carrier has to prepare and issue one before taking your vehicle. Alongside it, the driver fills out a vehicle condition report at pickup, noting any existing dents, scratches, or chips. That report is the baseline everyone compares against when the car is delivered.

Here is why that matters for prep. The whole inspection rests on the driver being able to see the car’s actual condition. A vehicle caked in road grime hides scratches, so genuine damage that happens in transit can get lost in vague notes, and pre-existing wear can be argued either way. Federal guidance on moving your belongings makes the same point in a related context: your ability to recover for loss or damage can depend on the notations made on the paperwork, so the condition record needs to be accurate before you sign. Prepping the car is how you make that record clean and verifiable.

Good prep also keeps the loading itself smooth. Drivers work on schedules built around several pickups, and a car that won’t start, has loose junk rolling around inside, or is too heavy with a full tank slows the line down. The better your car is ready to roll on and off the ramp, the less friction there is for everyone.

Clean, Photograph, and Document Your Car’s Condition (for the Inspection Report)

Wash the car a day or two before pickup, inside and out. A clean exterior is the single most useful thing you can do for the inspection, because every existing mark shows clearly and nothing can hide behind dirt. Pay attention to the lower panels, the bumpers, and the wheels, where chips and curb rash tend to collect.

Once it’s clean and dry, build your own record. Walk around the car and take clear, well-lit photos of every panel, all four corners, the roof, the wheels, the windshield and lights, and any spot that already has damage. Get close-ups of existing scratches, dents, and cracks, then a few wider shots that show the whole car. Time-stamped photos or a short video are ideal, since the date is part of what makes them useful later. Do the same with the odometer reading.

When the driver arrives, they will do their own inspection and write up the condition report. Go around the car with them rather than handing over the keys and walking away. Compare what they note against what you see, make sure existing damage is actually recorded, and if you disagree with something or think a mark was missed, say so before you sign. Federal moving rules are explicit that you have the right to note disagreement on the condition paperwork, and that you should keep your signed copy. At delivery you repeat the inspection and check the car against that same baseline before signing off. The claims process after delivery, and how shipping disputes get handled in general, belong to the broader auto-transport guides, not here; your job at prep time is simply to make the record airtight.

Inside the Car: Remove Personal Items and Reduce Weight

Empty the car out. Take everything that isn’t a permanent part of the vehicle: phone chargers, sunglasses, garage remotes, the contents of the glovebox and center console, anything in the trunk, and any loose change or clutter. There are two reasons, and both are practical.

First, carriers generally will not ship personal belongings inside the vehicle, and many state in their terms that anything left in the car travels at your own risk and isn’t covered. Auto transport insurance covers the vehicle, not a suitcase you stashed in the back seat. Second, loose items become projectiles. A trailer flexes and bounces over hundreds of miles, and a water bottle or a tool sliding around can crack a screen, scuff a door panel, or jam under a pedal. Items in cup holders, door pockets, and seat backs are the easy ones to forget, so check those specifically.

Weight is the other reason to clear things out. The more a car weighs, the more it costs the carrier to haul, and an overloaded vehicle can strain the loading ramps. Strip out heavy cargo and anything bolted in only temporarily. Also remove or retract loose external accessories that could catch wind or snag during loading, such as bike racks, rooftop carriers, removable antennas, and similar add-ons. Custom or low-clearance pieces get their own attention in the next section.

A handful of essentials can stay: your registration and proof of insurance in the glovebox are fine. Everything else comes with you.

Mechanical Prep: Fuel Level, Fluids, Battery, Tire Pressure, and Leaks

You want the car running well enough to drive on and off the trailer under its own power, but not loaded down or leaking. Walk through these before pickup.

  • Fuel level. Keep the tank low, commonly around a quarter full. That’s enough for the driver to load, reposition, and unload the car, while keeping weight down and leaving room in the tank. A nearly empty or modest level is the goal; a full tank adds weight you’re effectively paying to ship.
  • Fluids and leaks. Check underneath for drips and look at your oil, coolant, brake, and other fluid levels. A car that leaks can drip onto the vehicle parked below it on the trailer, and a serious leak can be grounds for a carrier to refuse the car. If you find a leak, get it addressed before pickup, and tell the driver about any minor seepage so they can position the car accordingly.
  • Battery and starting. The driver may start your car several times during loading and unloading, so the battery should hold a charge and the terminals should be snug. A dead battery is one of the most common things that stalls a pickup.
  • Tire pressure. Inflate the tires to the level on the placard in your driver’s door jamb or the owner’s manual. Tires that are too soft make ramp loading awkward and can get damaged, and over-inflated tires are more vulnerable too. Properly inflated tires roll on and off cleanly.

If the car doesn’t run at all, that’s a different job. Inoperable vehicles need a winch and special handling, which is something to settle with your carrier when booking rather than at the curb.

Disable Alarms, Note Custom Features, and Hand Off the Keys

An aftermarket alarm that arms itself and goes off mid-route is a headache no driver can fix on the road, so disable it or make sure the driver knows the exact sequence to silence it. The same goes for any kill switch, hidden cutoff, or quirky starting procedure. Turn off automatic toll transponders if you can, since a car riding on a trailer past a reader can rack up phantom charges.

Point out anything unusual about how the car behaves or what sticks out from it. Low front lips and spoilers, lowered suspension, fold-in mirrors, removable hardtops, and aftermarket bumpers all change how a car gets loaded and angled on the ramps, and a driver who knows about them in advance can plan around them. Fold in the mirrors if they fold, and retract or remove anything that protrudes.

Finally, the keys. The driver needs a working key or fob to start the car, steer it, release the parking brake, and move it on and off the trailer, so hand over a copy that does all of that. Keep your spare. If your car uses a valet mode or a separate valet key, that can be a clean way to limit access while still letting the driver do the job. Confirm the pickup and delivery contacts and phone numbers on the paperwork, do your final walkaround with the driver, and once the condition report matches reality and you’ve got your signed copy, you’re set.

A little prep turns a rushed curbside handoff into a quick, documented one. Clean car, clear photos, empty interior, sound mechanicals, and a key in the driver’s hand: that’s the whole job.

This is general information, not legal or insurance advice. Auto transport is regulated, carrier policies vary, and coverage terms differ between companies, so read your carrier’s contract and the bill of lading carefully and verify current requirements with the carrier and the official sources below.
