The short answer: somewhere between $1.2 billion and "more than you'd guess."
The longer answer tells a story about how a broken system quietly takes money from the people least able to lose it.
The headline number
The American Transportation Research Institute (ATRI) and multiple industry studies put the total in unpaid detention pay across the US trucking industry at approximately $1.2 billion per year.
That's not money in dispute. That's money that was contractually owed and simply never collected.
Breaking it down by driver
The math at the individual level is more visceral.
- There are approximately 350,000 independent owner-operators in the United States.
- The average driver loses an estimated $3,400 per year to unpaid detention.
- That's roughly $65 per week, or $13 per working day.
For a driver pulling $80,000 to $100,000 in gross revenue, that's 3.5% to 4% of total revenue lost to a combination of inaction and ignorance. That's a truck payment. That's three months of health insurance.
Why detention losses are systematic, not accidental
This isn't a random distribution of bad luck. The detention problem is structural.
Brokers have no reason to volunteer payment. A broker managing 500 loads a month loses nothing by waiting for drivers to ask. Most don't ask. Voluntary payment would mean brokers paying out millions a year without being prompted.
Drivers depend on brokers for future loads. Pushing back on a $150 claim risks a $1,500 load tomorrow. Even drivers who know they're owed money do the calculation and stay quiet.
Small claim sizes make litigation impractical. For a $100 to $300 detention claim, hiring an attorney at $300/hr is irrational. The system relies on drivers being rational in this way.
Documentation gets lost. Drivers who don't systematically save GPS data, BOLs, and rate confirmations can't prove their claims even when the underlying facts are clear.
The facilities problem
Not all detention is equal. Research consistently shows that certain facilities are significantly worse offenders than others.
Some distribution centers and warehouses are notorious in the driver community for extended wait times. The same facilities appear repeatedly in detention complaints, GPS logs, and FMCSA data.
This matters for two reasons:
- Drivers who know which facilities have bad detention histories can price that risk into their load acceptance decisions.
- Over time, aggregated claims data on bad-actor facilities creates leverage for systemic change — not just individual payments.
What the 2026 FMCSA rule changes
Before January 2026, the $1.2 billion figure was largely untouchable because drivers had no practical enforcement mechanism. The cost of recovering a $200 claim exceeded the value of the claim.
The new liquid surety bond requirement under 49 CFR Part 387 changes that calculation. For the first time, a driver with documentation has a formal, low-cost escalation path that creates real consequences for brokers who don't pay.
Whether this meaningfully reduces the $1.2 billion figure will depend on how many drivers actually use the mechanism. Right now, most don't know it exists.
The compounding effect
Detention losses compound in ways that don't show up in simple averages.
- Time cost: Hours at a dock aren't just lost pay — they're hours you could have spent on a paid run. The opportunity cost is higher than the detention rate suggests.
- HOS impact: Every hour of detention eats into your Hours of Service. A 3-hour detention event can cost you an entire additional driving day.
- Fatigue: Extended dock waits are mentally exhausting. The safety implications are real and under-studied.
The $3,400 annual figure is conservative. It doesn't capture the full cost.
