Two very different situations produce the same symptom, and telling them apart is the whole problem.
A carrier was assigned and cancelled. Ordinary and usually mechanical. Your shipment goes back onto the board and waits for the next carrier who fits.
No carrier was ever assigned. Your shipment has been listed and nobody has taken it. If that has been going on for a while, the reason is usually that the rate is below what any carrier will accept on that lane.
The first is a delay. The second is a problem that will not fix itself by waiting.
Why carriers cancel
The ordinary reasons, none of which involve anybody doing anything wrong:
A breakdown. A truck with nine vehicles on it that develops a mechanical problem is out of service until it is fixed.
A delay earlier on the route. Carriers run sequential stops. A customer who was unreachable, an access problem at a previous address, or weather can push a schedule far enough that later pickups no longer work.
A load that did not fill. A carrier building a route needs enough vehicles going the same direction to make it viable. If the load does not come together, the route changes.
A driver hitting hours-of-service limits at the wrong point, which is a federal safety rule rather than a scheduling choice.
Weather. A closed mountain pass or a major storm reroutes trucks and cancels stops.
None of these is a sign of a bad company. They are the normal friction of moving physical objects with trucks and people.
What re-dispatch means
When an assigned carrier falls through, your shipment goes back onto the load board and is offered to carriers again.
You are back where you were before dispatch, which means waiting for another carrier whose existing route fits your lane and dates. On a busy corridor that can be a day or two. On a thin lane, or with a narrow pickup window, it can be longer.
The thing to understand is that re-dispatch restarts the waiting clock, not the whole process. Your booking stands. What resets is the search for a truck.
Widening your pickup window at this point is the single most effective thing you can do, because it enlarges the pool of carriers who can absorb the shipment.
The questions that tell you which situation you are in
Call your coordinator and ask these specifically. Vague answers are informative.
"Was a carrier ever assigned to my shipment?" A clear yes with a legal name and USDOT number means a real carrier existed. Hedging means it may never have been dispatched.
"What is the carrier's name and USDOT number?" For a current assignment, you are entitled to this. Refusal is a serious signal.
"Why did the carrier cancel?" Breakdown, route change, weather, or a delay upstream are ordinary answers. "The market moved" is a different kind of answer.
"Is my shipment currently listed, and at what point?" You want to know whether it is actively on the board.
"How many carriers have looked at it?" A coordinator working your shipment will know roughly. One who does not may not be working it.
"What would change the outcome?" A real answer names a wider window, a more accessible pickup point, or a rate adjustment. A non-answer means nobody is problem-solving.
The pattern worth recognizing
There is a specific failure mode that looks like bad luck and is not.
A quote comes in well below every other quote you received. You book it. The shipment is listed. Nothing happens for a week. Then a call explains that the market has shifted and the price needs to go up, and by now your dates are close and you have no time to start over.
The mechanism is simple: the quoted rate was never one a carrier would accept for that lane, so no carrier took it. The shipment was never going to move at that number.
The tell is not the delay itself. It is the combination of an unusually low quote, extended silence, and then a price conversation. If that is your situation, you are not experiencing bad luck.
What you can actually do
Widen the pickup window. More than anything else, this improves your odds.
Be flexible on the pickup point. Meeting a driver at a commercial lot near the interstate rather than requiring a hard-to-reach residential address can move a shipment from a thin lane to a dense one.
Check your vehicle disclosure. An inaccurate description, especially undisclosed non-running condition or wrong dimensions, causes refused pickups and repeated dispatch failures. Confirm what is on the listing matches the vehicle.
Ask about expedited service if your dates are now tight. Expedited transport prioritizes dispatch, which is exactly where you are stuck.
Get everything in writing. Dates, promises, and rate discussions. If this becomes a dispute, contemporaneous written records are what matter.
When to walk away
There is no universal threshold, but a combination of these means it is time:
- No carrier has ever been assigned after a week or more on a route that is not remote
- Your coordinator cannot or will not name a carrier
- The rate conversation has changed since booking
- Answers have become vague or you are chasing them
- Your dates are now at risk and nothing concrete is being offered
Before cancelling, read the terms you agreed to. Cancellation conditions vary between companies and are set out in the agreement you signed, and Vanta's are published in our refund and cancellation policy.
If you do start over, get quotes from more than one company and treat an unusually low number as a warning rather than a win. A realistic rate is what gets a carrier to take the load.
For serious problems with a broker or carrier, complaints can be filed with FMCSA through the National Consumer Complaint Database.
Most stalled shipments come down to the pickup window, the accessibility of the address, or a rate that was never realistic. You can see how dispatch actually works, including what happens between booking and a carrier being assigned, which makes the delay a lot easier to read. ---
