Three different policies touch a typical car shipment, and they do completely different jobs. Only one of them pays if your vehicle is damaged in transit.
The carrier's cargo insurance covers damage to the vehicles the carrier is hauling. This is the policy that responds.
The broker's surety bond guarantees the broker pays the carriers it hires. It is a financial guarantee to the industry, not vehicle insurance, and it will not pay for a dented door.
Your own auto policy covers your vehicle under your terms, which may or may not extend to a car in the custody of a commercial carrier. That is a question for your insurer, not an assumption.
Most confusion about car shipping insurance comes from these three being blurred together, usually by companies saying "fully insured" without specifying by whom or for what.
What cargo insurance covers
Cargo coverage responds to damage the carrier is responsible for. In practice that means damage arising from loading and unloading, from securement failure, from an accident involving the transport truck, or from equipment malfunction on the trailer.
It generally does not respond to:
Pre-existing damage. Anything recorded on the condition report at pickup is excluded by definition. This is why the pickup inspection matters as much as it does.
Mechanical or electrical failure unrelated to handling. A battery that dies over eight days on a trailer is not transport damage.
Personal belongings inside the vehicle. The policy attaches to the vehicle. Items inside it are outside the covered property.
Inherent exposure on open transport. Rain, dust, and road film are what open transport is. They are not evidence of negligence.
Acts of God. Hail, flood, and similar events are typically excluded from standard cargo policies.
The organizing principle is worth holding onto: cargo insurance covers what the carrier did, not what the journey involved.
Coverage amounts vary, and nobody's published number is yours
You will see specific coverage figures quoted across the industry as though they were standard. They are not. Limits vary by carrier, by equipment type, and by individual policy. Enclosed carriers frequently carry higher limits than open carriers, and even that is not universal.
Two things nobody mentions:
Cargo policies often carry a deductible, and who bears it can depend on the carrier's terms. Worth asking about.
A per-load limit is not a per-vehicle limit. A policy limit that sounds generous may be shared across nine vehicles on a trailer. If your vehicle is worth a substantial fraction of a stated limit, ask specifically how the coverage applies per vehicle.
For an ordinary daily driver, none of this is worth the effort. For a vehicle where a total loss would be financially serious, all of it is.
How to actually verify coverage
This is where most advice stops short, and it is the part that protects you.
A certificate of insurance emailed to you proves very little on its own. Certificates are easy to produce and easy to send after a policy has lapsed. Fabricated certificates are a known problem in this industry.
Federal insurance filings are different. They must be submitted to FMCSA by the insurer rather than by the company being insured, which makes them substantially harder to fake than anything sent to you by email. FMCSA's Licensing and Insurance system shows whether filings are active for a given USDOT number.
So the verification is: get the assigned carrier's legal name and USDOT number, check that operating authority is active, and check that insurance filings are current at the source. If a company sends you a certificate and the federal record shows no active filing, believe the federal record.
Verify the carrier, not just the broker. If you booked through a broker, the company you first spoke to is not the company hauling your car. The cargo policy that matters belongs to whoever is assigned. Ask for their details once dispatch is confirmed.

Where your own policy fits
Your auto policy is not a substitute for cargo coverage and it is not irrelevant either.
Call your insurer and ask specifically: does my comprehensive coverage apply while the vehicle is being transported by a commercial carrier? The answer varies by insurer and by policy, and a general assumption in either direction is not useful.
Keep the policy active through the shipment. Do not let it lapse mid-move, particularly if the vehicle is financed and your lender requires continuous coverage.
Tell your insurer if the garaging address is changing. That affects your policy independently of the shipment.
For collector vehicles, agreed-value policies often have specific provisions about transit. Read them or ask your agent.
Supplemental and gap coverage
Some companies offer additional coverage as an add-on, and third-party transit insurance exists separately.
Whether it is worth it comes down to the gap between your vehicle's value and the assigned carrier's actual limit as it applies per vehicle. If that gap is meaningful, supplemental coverage addresses something real. If your vehicle sits comfortably within the carrier's coverage, you are buying protection you already have.
Two questions before purchasing any add-on:
What specifically does it cover that the cargo policy does not? A clear answer names exclusions or limits. A vague answer about "extra peace of mind" is not an answer.
Who underwrites it and how is a claim filed? Coverage sold by a broker but underwritten by a third party involves a different claims process than the carrier's cargo policy.
For genuinely high-value vehicles, the more effective protection is usually equipment and carrier selection rather than an add-on. Enclosed transport with a carrier carrying appropriate limits reduces the risk rather than insuring against it.
Documentation is the other half of coverage
Insurance only responds to damage you can demonstrate happened in transit. That demonstration comes from the condition report signed at pickup and delivery, and from your own photographs.
A comprehensive photo set before pickup, a properly conducted delivery inspection, and any new damage noted on the paperwork before signing will do more for a claim than any amount of coverage that you cannot prove applies. Our guide to the bill of lading and inspection process covers how to build that record.
Coverage is worth understanding before you book rather than after something happens, and most of it comes down to which carrier is assigned. You can see how the process works from booking through dispatch, including when you are told who is carrying your vehicle. ---
