How Auto Transport Load Boards Work (And Why Your Car Sits for Days)

Your broker doesn't own a single truck. They post your car on a software platform called a load board, and random carriers across the country bid on it. Understanding this process explains why your car sits for days, why the price changes, and who is actually responsible when something goes wrong.

What a load board is

Central Dispatch is the dominant load board in the auto transport industry — a private, subscription-based marketplace where licensed brokers post vehicle shipment orders and carriers browse and accept them. Think of it as Craigslist for truck drivers, except only licensed industry participants can access it.

When you book with a broker and pay your deposit, they create a listing on Central Dispatch within hours. That listing includes your pickup and delivery locations, vehicle type, your broker's offered carrier pay, and a first available date. Carriers browsing the board see hundreds of these listings at any given time and pick the ones that fit their routes and pay rates.

Why your car sits for days

Your car sits when the carrier pay offered is too low for the route. Carriers are running businesses — they accept loads that make financial sense for their current position and route. If your broker listed your Phoenix-to-Atlanta shipment at $400 carrier pay on a week when three other brokers listed the same route at $500, carriers skip yours.

The broker then faces a choice: raise the carrier pay (which cuts into their margin) or wait. Many wait. Some call to tell you; most don't. The result is a job that sits on the board for 5, 7, or 10 days while the broker quietly bumps the carrier pay $25–$50 at a time.

What "carrier assigned" actually means

When a broker tells you a carrier has been assigned, it means a carrier accepted your job on Central Dispatch. It does not mean:

• The carrier has confirmed a specific pickup date and time with you
• The carrier is definitely picking up your car
• The carrier has any relationship with you — they only know your broker

Carriers can cancel accepted loads. When this happens, your job goes back to the board. The broker may or may not tell you this happened. Some brokers use "carrier assigned" status to trigger non-refundable deposit clauses before the carrier has actually committed.

Who the carrier is — and why it matters

Until the moment of pickup, you often don't know which carrier will arrive. The carrier is a separate company from your broker — sometimes a large fleet, sometimes a single owner-operator with one truck and an MC number. Their insurance, their equipment, and their professionalism vary enormously.

Under FMCSA regulations, the broker is responsible for ensuring the carrier they dispatch is properly licensed and insured. If the broker dispatches an underinsured or unlicensed carrier and your car is damaged, the broker's bond is your backstop — but recovering from it is slow and often incomplete.

The price change problem

In a slow market, brokers may call you to ask for a higher price — framed as "the carriers are quoting higher than expected." What's actually happening is that the broker underpriced the job to win your business, and now they need to raise the carrier pay to get anyone to accept it. You are being asked to cover the broker's underquoting mistake.

You are not obligated to accept a price increase. If your contract specifies a price, that is the price. You can cancel and request a full refund if the broker cannot honor the original quote.

How to use this knowledge when booking

• Ask the broker what carrier pay they're listing. A reputable broker answers this honestly. The carrier pay should be roughly 60–75% of your total quote. If it's 40%, your car will sit.
• Avoid the lowest quote. Ultra-low quotes mean ultra-low carrier pay, which means a long wait or price renegotiation later.
• Ask how long they've been moving this specific route. Brokers with established carrier relationships on your route move cars faster.
• Get the carrier's name, MC number, and insurance certificate before pickup day. A broker who can't provide this 24 hours before pickup is working without a confirmed carrier.
