Ask a driver what wrecked their week and they will not lead with a rate. They lead with the dock.
You know the one. Appointment said 9 a.m. They rolled up at 8:40, checked in with a guy behind a sliding window who barely looked up, and then sat. And sat. Nobody came out. The staging lot was gravel and there was one picnic table with a missing bench and a vending machine that took cash only. Around 1 they finally got a door. By the time they pulled out, half the day was gone and the load still had to be somewhere by morning. We hear about that dock. The driver tells the carrier, the carrier tells us, and the next time freight out of that building comes across the board, everybody already knows.
Somewhere along the way the whole industry decided detention was a billing problem. Something you argue about later, on an invoice, in dollars. I want to talk you out of that, because the invoice is the least of it. The thing sitting under all that wasted time is a safety problem, and once you see the numbers on it you cannot really unsee them.
What Detention Actually Does to a Driver
Nobody has ever agreed on what detention even means, which is part of the problem. The rough rule everyone works off of is that a driver eats the first two hours at your place as the price of the stop, and anything past that is detention. The whole visit is dwell time. When it runs long, the driver is the one holding the bag.
It happens more than you would think. FMCSA research pegged drivers landing in detention on something like one stop in ten, and when it hits, it is not a five-minute thing. It averaged around an hour and a half past that two-hour cushion. And here is the one that ought to bother the mid-sized shippers reading this. That same research found the smaller and medium carriers getting stuck in detention roughly twice as often as the big fleets, about 19 percent of their stops versus 9 percent. So the owner-operator, the guy who is his own dispatch and his own mechanic, is the one your slow dock hammers the hardest.
And nobody is paying him to sit there. He is parked on your gravel, meter running in his head, watching the hours he actually gets paid for burn off because your building is behind.
The Safety Math Nobody Puts on the Dashboard
Here is where I stop talking about it as an annoyance.
The DOT Inspector General went and did the math on how long drivers sit against how often they crash. Every 15-minute bump in average dwell time pushed a driver's expected crash rate up by 6.2 percent. Chew on that for a second, because fifteen minutes is nothing. That is how long it takes to find a bathroom and grab a coffee, and it moves the odds of a wreck in a way you can measure.
Then the number that honestly changed how I think about a loading schedule. Same study figured that if you shaved one minute off the average detention time across the country, you would prevent something like 400 crashes a year. One minute, spread across every dock in America, is four hundred wrecks that do not happen. That is real leverage, and it is sitting right there in your appointment book, and almost nobody running a warehouse has ever once thought of their dock doors as a highway safety tool.
The mechanism is not mysterious. A driver who loses four hours in your lot still has to be at the receiver on time, and still owes the same truck payment on the first of the month. So he makes it up the only place he can, which is the road. He drives tired instead of shutting down. He crams the trip into whatever he has left on the clock and prays. Fatigue is already near the top of the list for what kills people in truck wrecks, and a long wait at a dock is about the most efficient way there is to build a tired driver.
The Clock You Are Spending Is Not Yours
You cannot really get this until you understand how boxed-in a driver actually is, because it is tighter than it looks from inside a warehouse.
The rules give a driver a 14-hour window from the minute they clock on. Eleven of those hours can be driving. When the 14 is up, they are parked for the night, finished or not. That clock does not stop for you. It does not care that your forklift threw a code, or your shipping office was slow with the BOL, or somebody in scheduling stacked three appointments into the same slot. Every minute the driver spends in your yard is a minute gone off the 14, and there is no button to give it back.
Run it forward from the cab. He shows up with room to spare, easily enough window to make the drop. Four hours later he is pulling out with your freight and a clock that will not reach. Now he is stuck with a lousy call, and you are the one who handed it to him. Blow through his hours and gamble on a violation or worse, or shut it down early, sleep in some lot, and eat the missed appointment he was busting his tail to hit. That was not weather. That was not I-40 traffic. That was your dock, full stop.
That is the part that never quite lands for shippers. When you sit on a driver, you are not burning your own time. You are burning his, and his is rationed by the federal government.
Washington Is Finally Watching the Dock
Detention used to be the thing everybody moaned about and no regulator would go near. That is changing right now, this year, and it is moving faster than most people in the business realize.
The FMCSA has a real detention study going, pulling actual numbers off thousands of drivers through their ELDs and dispatch software, trying to finally measure this thing across the whole industry instead of guessing off a handful of fleets. And DOT, under Secretary Sean Duffy, put out something they are calling the Pro-Trucker Package, aimed at the stuff drivers deal with every day. Tucked inside it are a couple of hours-of-service pilots running through the spring and summer, and one of them goes straight at this. It would let a driver pause that 14-hour clock, park up to three hours of certain non-driving time, detention included, off to the side, so getting stuck at a bad dock does not automatically eat his whole day.
Read the fine print and there is a tell in it. FMCSA has no authority over shippers and receivers. It cannot fine you for a slow dock, and it knows it, which is why its own paperwork keeps nudging at private-sector decisions as the fix. That is government-speak for the fact that the only people who can actually kill detention are the ones reading this, not the agency writing the report. The light is on the dock now. And the accountability that comes with it is going to be the reputational kind, run through the carriers who quietly decide whose freight is worth putting a truck on.
What a Good Dock Looks Like
Barely any of the fix costs money, which is the maddening and also encouraging part. Most of it is just deciding a driver's time is real and then behaving like it.
Count it first. You cannot fix a wait you refuse to measure, and I would bet a lot of facilities genuinely do not know how long trucks sit once the appointment time slides by. Get a clock on it, pick a target you would be willing to say to a driver's face, and go find the shifts and the lanes where it falls apart. Once you are actually looking, fix the appointment book so it matches how long the work really takes instead of how long you would like it to. If you are blocking 30 minutes for something that eats 90 every single time, that is not a schedule, that is a line dressed up as one, and the driver pays the tab. Overbooking your doors is just detention you penciled in ahead of time.
Then there is the human stuff, which runs close to free and which drivers clock harder than anything. Get them checked in quick. Treat them like a guest instead of a hassle that showed up at your gate. Give them a clean restroom and somewhere to wait that beats baking in the cab in a July lot. Tell them what is going on when things back up, rather than leaving them staring at a closed door. Keep the forklift moving and have the paperwork ready so the truck turns and gets gone. None of that shows up on a P&L. All of it decides whether a driver is happy to see your name pop up on the next load or quietly hoping for anything else.
The shippers who already get this are winning a game the rest do not even know is being played. Carriers keep scorecards on facilities now, some written down and some just carried around in a dispatcher's head, and a shipper who wastes drivers gets remembered the second capacity tightens up. Uber Freight has made the point that a rough dock can move how a carrier sees a whole account, enough to shift how they price it and where they put it in line. Your dock is your reputation, standing there in concrete and forklifts. Drivers talk, dispatch listens, and the freight drifts toward the buildings that treat the people hauling it like they matter.
The Bottom Line
We filed detention under accounting a long time ago and it never belonged there. The best data anybody has ties the hours a driver loses in your lot straight to how likely he is to crash on the way out, and 6.2 percent more crash risk for every extra 15 minutes is not a number that should be hiding under an accessorial charge. Every minute he waits comes off a clock the federal government caps, and the choice you force by spending it is sometimes the choice between a load that is late and a driver who makes it home.
The hopeful thing is that this is one of the few problems in freight you can actually fix from your own side of the fence, starting this week, without spending much beyond attention. Put a real clock on the wait. Mean the appointment when you set it. Treat the driver like a person whose time is worth exactly as much as yours. Do that and you protect the people hauling your freight, you get out ahead of a regulatory push that is clearly building, and you turn your dock into a place carriers send their best drivers on purpose. Those two dangerous hours do not have to happen at your building. Whether they do is on you.

Research for this piece drew on the U.S. Department of Transportation Office of Inspector General study linking dwell time to crash rates and lost driver earnings, and on FMCSA detention research finding how often drivers are detained and how much longer smaller carriers wait, along with the agency's current driver detention data-collection study. Detail on the driving window and daily limits came from FMCSA hours-of-service regulations, and information on the Pro-Trucker Package and the 2026 Flexible Sleeper Berth and Split Duty Period pilot programs, including the proposal to let drivers pause the 14-hour window during detention, came from the Federal Register and FMCSA program materials. Perspective on dock experience and carrier facility scorecards drew on Uber Freight and FreightWaves reporting.
