Drop and hook vs live loads
Two loads can pay the same and still be worth very different money once you count the hours at the dock. Here's how drop and hook and live loads compare, what the hours of service rules say about waiting time, and what to ask before you book.
Key takeaways
- A live load or unload means you wait while the dock loads or unloads your trailer. Drop and hook means you drop one trailer and hook another that's ready.
- Waiting at a shipper and time loading or unloading is on-duty time (49 CFR 395.2), and your 14-hour window keeps running while you wait.
- On-duty, not-driving time does count toward the 30-minute break (49 CFR 395.3(a)(3)(ii)), so you can take your break at the dock.
- A 2018 DOT Inspector General report found that a 15-minute rise in average dwell time raised the expected crash rate by 6.2%. Get detention terms on the rate con.
The two kinds of stops
- Live load: you back into a door and wait while the shipper loads your trailer. Live unload is the same at the receiver.
- Drop and hook: you drop the trailer you brought and hook one that's already loaded or empty. Often you don't need a door at all.
- Preloaded trailer: the shipper loaded a trailer ahead of time. With power only, it's usually from a trailer pool.
- Appointment vs first come, first served: an appointment gives you a time slot. First come, first served (FCFS) means you wait in line during open hours.
A load can mix them: a live load at pickup and a drop at delivery, for example.
How each one hits your hours
- Waiting is on-duty time. Time at a shipper's or receiver's property waiting to be dispatched, and time loading, unloading or supervising it, is on-duty time (49 CFR 395.2), unless your carrier has relieved you from duty.
- The 14-hour window doesn't stop. You can't drive after the 14th hour since coming on duty (49 CFR 395.3(a)(2)), so a 4-hour live unload can cost you the miles to your next load.
- The 30-minute break can happen at the dock. Since 2020, the break can be off-duty, sleeper berth or on-duty not driving time (49 CFR 395.3(a)(3)(ii)). FMCSA's driver guide gives loading or unloading as an example.
- Logging off duty is only allowed when you're relieved of all duty and responsibility for the vehicle. Time resting in the sleeper berth isn't on-duty time.
For splitting your 10 hours around a long wait, see the sleeper berth split guide, the hours of service basics and the HOS calculator.
What waiting really costs
- The DOT Office of Inspector General (report ST2018019, January 2018) estimated that detention cut for-hire truckload drivers' earnings by $1.1 to $1.3 billion a year, about $1,281 to $1,534 per driver.
- The same report found that a 15-minute increase in average dwell time raised the expected crash rate by 6.2%.
- FMCSA started a detention data study in 2024 with about 80 carriers and 2,500 drivers. As of October 25, 2026 we found no published results.
- In September 2025 FMCSA proposed a pilot program that would let some drivers pause the 14-hour clock once, for 30 minutes to 3 hours, at a pickup or delivery. It's a proposal for a pilot, not a rule.

Side by side
| Drop and hook | Live load or unload | |
|---|---|---|
| Time at the stop | Usually short | Depends on the dock; can be hours |
| Your 14-hour window | Mostly spent driving | Can be eaten by waiting |
| Equipment | Needs a trailer ready to swap, or a pool trailer | Works with your own trailer |
| Detention | Rare | Common; get the terms in writing |
| Lumper fees | Rare | Possible at grocery and food warehouses |
| Planning the next load | Easier to predict | Harder; add a buffer |
What to check on the rate con
- Is each stop live, drop or preloaded? If it just says "pickup", ask.
- Appointment time or FCFS hours, and what happens if you're early or late.
- Detention: how many hours free, the hourly rate after that, and how you must report arrival and departure. See how to get detention paid.
- Lumper: who pays and how you get reimbursed. See TONU, layover and lumper pay.
- For drops: where the empty or loaded trailer goes, and the trailer number.
Our rate confirmation guide covers each line.
Build a better week
- Price live loads for the hours, not just the miles. Use the load profit calculator with a realistic dock time.
- Put a live unload late in your day, when the wait can roll into your 10-hour break, rather than first thing.
- Keep a list of docks that load fast and pay detention, and go back to them.
- A dispatcher can book the next load around a long unload so you don't sit empty. See dry van dispatch and reefer dispatch.

Questions carriers ask
Is drop and hook better than a live load?
Usually faster, because you don't wait at a door, which saves your 14-hour window. But it needs a trailer ready to swap. A live load with fair pay and detention terms can still be a good load.
Is waiting at a shipper on-duty time?
Yes. Waiting at a shipper's or receiver's property to be dispatched, and time loading or unloading, is on-duty time under 49 CFR 395.2, unless you've been relieved from duty.
Can I take my 30-minute break while I'm being loaded?
Yes. Since 2020 the 30-minute break can be on-duty, not-driving time (49 CFR 395.3(a)(3)(ii)), and FMCSA's driver guide gives loading or unloading as an example.
Does the 14-hour clock stop during detention?
No. The 14-hour window keeps running. FMCSA proposed a pilot in September 2025 to let some drivers pause it at a pickup or delivery, but that isn't a rule.
How do I get paid for waiting?
Get the detention terms on the rate confirmation before you book, record your arrival and departure times, tell the broker while it's happening and invoice it with proof.
