Truck Driver Detention Pay, Explained: How the Calculation Actually Works

Appointment was 8 a.m. You backed in at 7:50. Now it's noon, the dock doors are still closed, and nobody's told you why. Somewhere in your carrier's rate confirmation there's probably a line about detention pay — a dollar amount for exactly this. Whether that line ever turns into money on your settlement is a different question, and the honest answer starts with something most drivers don't expect: there's no federal rule that says you have to be paid for this at all.

Detention pay is a contract term, not a law

Start with what detention pay actually is, because the name makes it sound like a regulation when it's really a private agreement. Detention pay is compensation a shipper or broker agrees, in a contract, to pay a carrier when a driver is held at a facility past an agreed-upon free time. Nothing in the Federal Motor Carrier Safety Regulations sets a detention rate, a grace period, or a minimum payment. Those terms come from whatever's written into the rate confirmation or brokerage agreement for that specific load — which also means they can be missing entirely.

That gap hasn't gone unnoticed at the federal level. The DOT Office of Inspector General estimated in a 2018 report that excessive detention time cuts truckload driver earnings by an estimated $1.1 billion to $1.3 billion a year (DOT OIG report on driver detention). The 2015 FAST Act directed FMCSA to work on collecting data about these delays, and the Infrastructure Investment and Jobs Act later directed a further study — through the Transportation Research Board — on how different driver compensation methods, including detention pay, affect safety. As of this writing, that's research and rulemaking activity aimed at understanding the problem. It is not a rule requiring anyone to pay you for the time. If a future rule changes that, it'll be news; today, your actual entitlement lives in your contract, not in a federal regulation.

The one thing that is federally certain: the clock doesn't stop

Here's the part regulation does reach, and it's worth knowing even though it has nothing to do with getting paid.

Under the hours-of-service rules in 49 CFR Part 395, on-duty, not-driving time — which is what you're accumulating while you sit at a dock waiting to be loaded or unloaded — counts against your 14-hour on-duty window and your 60/70-hour weekly limit the same as any other on-duty time. Off-duty time and a qualifying sleeper-berth split are the recognized ways to pause that clock; simply waiting at a shipper is not one of them. So a five-hour detention doesn't just cost you money you may or may not get back — it can cost you five hours of the window you had left to drive that day, whether or not the load is worth waiting for. We've laid out how the 14-hour window and the weekly 60/70 limit work together in more detail in the 34-hour restart guide.

FMCSA has been testing a narrow exception to this. A 2025 pilot program lets a limited group of participating drivers pause the 14-hour window once per day, for 30 minutes to 3 hours, for an off-duty, sleeper-berth, or on-duty-not-driving break taken at a pickup or delivery location — detention time is explicitly one of the situations it's meant to cover. That's a pilot with a defined participant group, not a rule that applies to drivers generally, and FMCSA has said it's still reviewing results before any wider rollout. Don't plan your day around a rule you're not enrolled in.

The basic calculation

Once you know the terms your specific load is running under, the arithmetic itself is simple — it's a grace period, then a rate, applied to whatever time is left over.

Detention pay = (total time held − free/grace time) × detention rate

A typical structure, and this varies by contract:

• Free time, often 2 hours from the scheduled appointment time or arrival, whichever the contract specifies — this portion is unpaid by definition.
• Detention rate, commonly somewhere in a $25–$100 per hour range depending on the broker, the freight, and the lane — set entirely by that load's paperwork, not by any external standard.
• Detention time, the hours held beyond the free period, usually rounded to some increment (often the half hour or hour) per the contract's own rounding rule.

Worked example. Appointment and grace period: 2 hours free. Detention rate: $50/hour. You arrive on time and aren't loaded until 5 hours after your appointment.

• Billable detention time: 5 hours − 2 hours = 3 hours.
• Detention pay owed (to the carrier, under the rate confirmation): 3 × $50 = $150.

A two-stop day, because detention often gets tracked separately per stop rather than added up across the whole day:

• Stop A (pickup): held 3 hours, 2 free → 1 billable hour × $40/hour = $40.
• Stop B (delivery): held 4 hours, 2 free → 2 billable hours × $40/hour = $80.
• Total for the day: $40 + $80 = $120 — not the $200 you would get by pooling the day (7 hours held, one 2-hour grace, 5 billable), because each stop's grace period resets and applies on its own, which is the common structure but, again, something your own paperwork should confirm rather than assume.

The number that actually matters to you: who gets paid

The arithmetic above computes what the broker or shipper owes the carrier. Whether any of that reaches you, the driver, depends on a second and completely separate agreement — your pay package with your carrier.

• Company drivers are typically paid under whatever their carrier's pay policy says: some carriers pass detention pay through to the driver dollar-for-dollar, some pay a flat detention rate that doesn't match what the carrier collected, and some don't pay drivers for detention at all even when the carrier gets paid for it. There's no rule requiring a pass-through; it's a term of your own employment or contractor arrangement, and it's worth reading rather than assuming.
• Owner-operators and lease-on drivers who negotiate loads more directly are closer to the broker-facing side of this, but even then, the specific rate confirmation for that load is what controls — not a general industry norm.

If you don't know your own carrier's detention pay policy, that's the actual first question, ahead of any math about a specific late dock.

Why this usually isn't an overtime question either

It's tempting to assume that hours spent waiting, once they push a week long enough, would trigger time-and-a-half the way they might in a lot of other hourly jobs. For many interstate truck drivers, that assumption doesn't hold, because of a separate piece of federal law: the motor carrier exemption under 29 U.S.C. § 213(b)(1) of the Fair Labor Standards Act, interpreted further at 29 CFR Part 782.

In general terms, drivers whose work affects the safe operation of a commercial motor vehicle over 10,000 pounds in interstate commerce, for a motor carrier the Secretary of Transportation has authority over, are commonly treated as exempt from the FLSA's overtime requirement — meaning detention hours that push a week past 40 don't automatically become time-and-a-half the way they generally would for a non-exempt hourly employee. A 2008 technical-corrections law narrowed that exemption for drivers of smaller vehicles (10,000 pounds or under) in some circumstances, restoring overtime eligibility for a subset of drivers. Whether the exemption applies to your specific role turns on your vehicle's weight, your carrier's interstate operating authority, and your actual job duties — the (DOL Fact Sheet #19 on the motor carrier exemption) is the primary place to check the current federal test, and it's worth checking rather than assuming either way.

What to check before you assume you're owed anything

1. Does your rate confirmation or contract mention detention pay at all? If it doesn't, there's likely nothing contractual to collect on that load, however long you waited.
2. What's the free/grace period, and does it apply per stop or per day? The two-stop example above only works out to $120 because each stop resets separately — confirm which structure your paperwork actually uses.
3. What's the detention rate, and is it the same number the carrier is collecting from the broker, or a separate, lower number the carrier pays you? Those are commonly two different figures.
4. Do you have your own timestamps? Check-in time at the guard shack, the time you were actually called to a door, and the time you pulled out — ideally backed by your ELD log or a signed note from the shipper — are what turns a dispute into a documented claim.
5. Are you asking your dispatcher, or your carrier's settlement department? Detention claims usually have to be submitted, sometimes on a deadline, rather than applied automatically.

None of this is legal or financial advice, and detention pay terms vary enormously by carrier, broker, and even individual load. If a specific dollar amount is in dispute, your carrier's settlement department, your contract's own dispute process, or an attorney familiar with transportation contracts is the right next step — not a general explainer.

Where the schedule comes in

The frustrating part of detention is that it rarely shows up on anything you can plan around in advance — it's a delay that eats into a day you'd already mapped out, and by the time you know it's happening, your options for the rest of the week have usually already narrowed.

Duty Pals doesn't track dock times or detention claims, but it does keep your actual duty pattern — the days you're scheduled to run, and how a long day at one stop reshapes what's realistic for the rest of the week — visible further out, so a bad dock isn't also the first time you're seeing how it reshapes everything after it. Duty Pals is currently in pre-registration; you can sign up to be notified when it launches.

This article explains general concepts about detention pay and hours-of-service rules and is not legal or financial advice. Detention pay terms are set by private contracts that vary by carrier, broker, and load, and whether a specific job is covered by the FLSA's motor carrier exemption depends on facts specific to the vehicle, the carrier, and the role. Your carrier's settlement department, your contract's dispute process, or an attorney familiar with transportation law is the right resource for a specific claim.
