Short answer
Book the first load, then use the load board's reload and return-trip suggestions, or post your truck with Post A Truck up to two weeks ahead. Blocks and contracts reserve more work at once.
How do you book back-to-back loads on Amazon Relay?
One at a time: book the first load, then find a second that picks up near the first delivery, inside the hours your driver has left. Amazon's load board guide doesn't describe a way to book several spot loads in one action.
What helps you chain them on the board:
- Filters. Origin and destination (or a radius), equipment type, trailer status, load type, driver type, maximum stops, trip length, rate range, and pickup and delivery windows.
- Saved searches and alerts. Save the search you run from your usual delivery points. Relay also has email alerts and push notifications.
- All-in prices. The spot price includes the base rate, fuel surcharge and tolls, and you book at the listed price.
More on filters and timing in our Amazon Relay load board guide.
How do reload and return-trip suggestions work?
After you book, the board can suggest more loads for the same truck. Amazon says it suggests replacements for cancelled loads, return trips, and additional loads to continue a driver's journey.
They're suggestions, not bookings. Before you take one, check:
- Pickup window. Can your driver get there after the first delivery?
- Deadhead. How far is the empty run from the first drop to the next pickup?
- Hours. Does the driver have the drive time left (next section)?
Amazon also says personalized load recommendations come from your search history and saved searches.
How do you fit a second load inside Hours of Service?
Add up the first load, the deadhead and the second load, then compare the total to the hours your driver has left. Under FMCSA Hours of Service rules, a property-carrying driver can drive 11 hours within a 14-hour window after 10 consecutive hours off duty.
A checklist before you book load two:
- Driving time for load one, start to final stop.
- Deadhead driving from the last drop to the next pickup.
- Driving time for load two.
- Total driving under 11 hours? If not, it doesn't fit today.
- Does everything, including waits at the docks, finish inside the 14-hour window?
- Can the driver make the pickup window, not just the last minute of it?
Example with made-up numbers: 4 hours of driving, a 1 hour deadhead and 5 more hours is 10 hours, under 11. If dock time pushes the day past 14 hours, it still doesn't fit.
Some spot loads offer pickup time options at booking to allow for traffic, stem miles and Hours of Service. Not all do. Amazon also describes three driver setups:
| Setup | What Amazon says |
|---|---|
| 13-hour solo | One day of loads, including 11 hours of drive time |
| 37-hour solo | Two days of loads, with the 10-hour break taken outside base cities |
| Team | Two drivers trade off |
Can Post A Truck line up your next load?
Yes. Post A Truck lets you post when and where your truck is free, and Amazon books loads that match. Amazon's Post A Truck guide says you can post up to two weeks ahead, include or exclude cities, pick one-way or round trip, and set distance or duration limits. You set a minimum rate per mile.
Why it helps with a second load:
- Match outlook shows High, Medium or Low odds, based on the previous six weeks of loads.
- First access. Matched carriers see freight in their window before it reaches the load board.
- Block orders with the same start and end pay in full even if Amazon doesn't use the whole block.
Amazon says it will instantly book loads that match your criteria, so only post hours your driver can actually run. A post isn't a guaranteed match. Amazon doesn't publish how many posts you can have open at once.
Do blocks or contracts beat chaining spot loads?
They reserve more work up front, so you're not hunting for each next load. Whether they beat spot depends on your lanes, your grade and what the rates are that week.
| Option | How it works | Who can book |
|---|---|---|
| Spot loads | Last-minute loads booked one at a time | All grades |
| Block | A chunk of time you reserve trucks and drivers for, paid even if Amazon doesn't use the full block | Not listed on Amazon's grades page |
| Contract | Full or partial weeks of loads, booked in advance | B grade or better for new contracts |
| Auction | Contracts up to 6 months, bid in bulk, winning rate locked | C+ or better for most bids |
Amazon's grades page says carriers can lose booked contracts if they drop below C+. You get a grade after ten or more Relay loads in the last six active weeks, so new carriers start on spot. See Amazon's rate options for auctions, and our guide to what Relay pays.
What happens if you book too many and cancel?
It hurts your score. Amazon's performance score includes an acceptance metric that tracks how often you reject (cancel) loads you booked, including expired loads. The closer the cancellation is to pickup, the bigger the penalty.
Why it matters:
- Your overall score is your lowest metric. One weak metric sets your grade.
- Grades unlock work. B for new contracts, C+ for most auctions, and A+, A and B+ for early access to new spot loads.
- Amazon doesn't publish the penalty size for a cancellation, the score cutoff for each grade, or how long a single cancellation stays on your score.
The simple habit: don't book load two until you've done the hours math. More in our scorecard guide.
Can a tool book multiple loads for you?
Yes. Amazon's Post A Truck books matching loads for you, and third-party browser extensions exist. Whatever you use, you're responsible for your Relay account, so check Relay's terms.
Ask any auto-booker:
- Does it stop at a cap on how many loads it books?
- Does it respect a profit floor you set?
- Do you set the lanes and prices?

Where does NudoIQ fit?
NudoIQ is a Chrome extension that runs inside your signed-in Relay load board tab. It's an independent tool, not made by or affiliated with Amazon. Lane and equipment come from your Relay search. Autobook books loads that clear your Min Net Profit and Min $/Mile, and stops at your max-books cap (counted per START). A backhaul finder searches from where your load ends back toward home, and every load card shows net profit after driver pay, fuel, maintenance and deadhead.
