Detention

Hours of Service rules make detention time especially costly — time waiting at a dock counts against a driver's 14-hour on-duty window even if they're not driving. One hour of detention can cost a driver $50–$100 in direct pay loss and 60+ minutes of legally available drive time. A driver detained for 3 hours loses the equivalent of 150+ potential loaded miles in HOS capacity.

The financial impact compounds quickly. A driver who averages 2 hours of detention per load, 4 loads per week, at $75/hour is leaving $300/week on the table if they're not collecting it — $15,600/year. Most of that loss isn't the waiting itself; it's the HOS time eaten that prevents running another load.

Standard free time is 2 hours from the scheduled appointment or arrival. After that, the clock starts. Many rate confirmations specify $50–$75/hour detention — push for $75–$100/hour when negotiating loads at notoriously slow facilities like grocery DCs, automotive plants, and large retail distribution centers.

Documentation is the difference between collecting detention and losing it. Take a timestamped photo when you arrive and when you're released. Use your ELD's on-duty not-driving status as independent corroboration. Send a text or call to your dispatcher/broker when free time expires — this creates a paper trail. Many brokers pay detention disputes without argument when they see clear timestamps.

Detention also has strategic implications for load selection. Repeat loads at shippers with 4-hour average waits should command a rate premium to compensate. If a shipper consistently runs 3+ hours of free overtime, the real rate per mile on that load is lower than the paperwork shows.

Industries with the Worst Detention

Not all shippers are equal on wait times. Grocery distribution centers are consistently the worst offenders — average wait times of 3–5 hours are common at major grocery chain DCs like Walmart, Kroger, and Albertsons distribution facilities. These DCs operate on rigid inbound scheduling, and a single missed appointment can push you back 4–6 hours. Automotive plants (GM, Ford, Toyota, Stellantis supplier networks) operate on just-in-time manufacturing schedules, which sounds efficient but in practice means dock congestion spikes when production lines change over. Steel mills and metal distribution centers often run 4–8 hour waits due to the mechanical nature of loading coils, sheets, and structural steel. Home improvement chains (Home Depot, Lowe's) are also repeat offenders due to high freight volumes and complex inventory management.

Before accepting loads at known high-detention facilities, factor the expected wait time into your real rate calculation. A load paying $2.40/mile to a notorious grocery DC where you expect 4 hours of wait: 8 hours of driving plus 4 hours of detention equals a 12-hour day for $1,440 linehaul plus $240 detention at $60/hour totaling $1,680. That burns half your legal drive time. Running two shorter loads at a comparable rate with minimal detention could yield more total revenue in the same time.

Tracking Detention Patterns by Broker and Shipper

Building a personal detention log gives you data to make smarter load decisions over time. Track every load by broker name, shipper name, scheduled appointment time, actual release time, amount invoiced for detention, and whether it was paid. After 30–60 loads, patterns emerge clearly: certain brokers consistently book loads at slow facilities and dispute detention claims, while others pay without argument. Some shippers are reliably fast while others are consistently slow regardless of appointment time. This data directly informs how aggressively you price loads from those sources and whether you continue taking their freight at all.

Negotiating Detention Rates Before the Load

Detention is one of the most negotiable items in a rate confirmation. While a broker's first offer might specify $50/hour after 2 hours free, pushing to $75–$100/hour is achievable — especially on loads going to known slow facilities. The leverage is simple: if the broker knows their shipper regularly runs 4-hour waits, they expect to pay detention anyway. Getting $75/hour approved upfront costs the broker nothing if the load moves fast. Some experienced owner-operators negotiate tighter free time provisions on specific facilities: 1 hour free instead of 2 at locations known to run slow, effectively starting the detention clock sooner at problem shippers. For loads at the most egregiously slow facilities, some operators insist on drop-and-hook instead of live-load as a precondition for accepting the freight.

Why This Matters for Owner-Operators

Detention pay is one of the most commonly uncollected revenue sources in trucking. Industry surveys suggest fewer than 40% of detention hours that qualify for pay are actually invoiced. For an owner-operator running 15–20 loads per month, building the discipline to document and collect every qualifying detention hour can add $800–$1,500/month in revenue with no additional miles driven. Every hour of uncompensated detention is both lost pay and lost drive time — a double hit to your earnings. The brokers and shippers who pay detention reliably and on time are the ones worth building long-term relationships with.
