When you book car shipping, you usually deal with a broker, not the company that moves your car. The broker posts your shipment to a load board (usually Central Dispatch), where independent carriers, the companies that own the trucks, bid to haul it. A carrier accepts within 1–5 days, picks up your car within a 1–3 day pickup window, and delivers it in a timeframe that depends on distance (typically 1–3 days for short moves, up to 7–10 days coast to coast). You inspect and sign a Bill of Lading at pickup and delivery. Understanding this broker-carrier split explains why quotes vary, why pickup windows exist, and why prices sometimes change.
Broker vs. Carrier: The Key Distinction
A carrier owns the trucks and physically moves your car. A broker owns no trucks, it coordinates your shipment by connecting you with a carrier. The vast majority of companies you find online are brokers.
This single fact explains most of what confuses first-time shippers. When you get a quote from a well-known car shipping "company," you're almost always talking to a broker. They don't have a truck sitting in a lot waiting for your car. Instead, they act as a matchmaker between you and the thousands of independent trucking companies (carriers) operating across the country.
Broker
- Owns no trucks
- Posts your shipment to a load board
- Taps thousands of carriers nationwide
- Covers virtually any route
- Handles customer service and booking
- Most companies you find online
Carrier
- Owns and operates the trucks
- Physically transports your vehicle
- Bids on shipments via load board
- Limited to their own routes
- Often small or owner-operator businesses
- Registered with DOT and FMCSA
Neither model is a scam or inherently worse. Brokers exist because there are hundreds of thousands of small carriers, and no single carrier covers every route. The broker's job is finding the right truck for your specific route and dates. A good broker earns their fee through that coordination.
What Is a Load Board?
A load board is an online marketplace where brokers post vehicle shipments and carriers bid to haul them. The dominant one in auto transport is called Central Dispatch.
Think of it as a real-time auction that matches cars with trucks. When your broker posts your shipment, carriers who are already running that route, or planning to, see it and decide whether the offered price is worth their time. If the price is right, a carrier accepts and your car is scheduled. If no carrier bites, the broker raises the offered rate until one does.
This marketplace mechanic is the reason quotes are ranges rather than fixed prices. Your final cost depends on real-time supply and demand: how many carriers are running your route, how popular the lane is, the season, and how flexible your dates are.
The Step-by-Step Process
Here's exactly what happens from the moment you request a quote to final delivery.
You request a quote
You provide your origin, destination, vehicle type, and timeline. The broker gives you an estimated price based on current market rates for that route.
You book and the shipment is posted
Once you accept, the broker posts your shipment to the load board (Central Dispatch) at the agreed rate. No large upfront deposit should be required, reputable brokers charge at or after pickup.
A carrier accepts the job
An independent carrier running your route accepts the shipment, usually within 1–5 days. Popular routes fill fast; rural or off-corridor routes take longer or need a higher rate.
Pickup and inspection
The carrier arrives within a 1–3 day window, inspects your car, and documents its condition on the Bill of Lading. You sign it. This is your legal record, check it carefully.
Transport
Your car travels on the carrier's truck, often alongside other vehicles being dropped at points along the route. Carriers cover roughly 500 miles per day under federal driving-hour limits.
Delivery and final inspection
At delivery, inspect your car against the Bill of Lading before signing. Note any new damage in writing immediately, this is your protection for an insurance claim.

Most people should use a broker for the coverage and price competition. Booking a carrier directly only makes sense in narrow situations.
Brokers win on availability and price. Because they tap thousands of carriers, they can cover nearly any route and let carriers compete for your shipment, which keeps prices honest. The tradeoff is one extra layer between you and the truck.
Booking a carrier directly gives you a direct relationship and one less handoff, but carriers only run specific routes and may not have availability when you need it. For a standard consumer move, a reputable broker is almost always the more practical choice. Marketplaces like uShip sit in between, you post your shipment and carriers bid directly, cutting out the broker layer but also the broker's coordination.
Why This Explains Everything Confusing About Car Shipping
Once you understand the broker-carrier-load board structure, the three most common frustrations make sense:
Why quotes vary between companies: Different brokers estimate the load board rate differently. They're all pricing the same underlying carrier market, so quotes cluster, but they're estimates, not fixed prices.
Why you get a pickup window, not an exact time: Carriers run multi-stop routes and can't commit to an exact hour days in advance. A 1–3 day window is standard and not a red flag.
Why a quote sometimes rises after booking: If no carrier accepts the posted rate, the broker must raise it to get your car moved. Companies with a price-lock guarantee absorb that increase instead of passing it to you, which is why asking about price-lock before booking matters.
