Detention costs US trucking billions each year, and the fixes remain stuck in slow-moving commercial and regulatory gears, per the framing of a new Transport Topics piece running under the headline "Detention costs trucking billions — why is it so hard to fix?"

The Transport Topics piece anchors a freight debate that has run for more than a decade. Detention, in trucking's working vocabulary, is the clock that keeps running while a driver waits to load or unload at a shipper or receiver dock.

The mechanics are plain. A driver pulls into a facility at the appointed time. The dock is full. The paperwork is not ready. The forklift breaks down. The driver waits. The carrier keeps paying wages, fuel, insurance and equipment time. The driver does not move on to the next load.

What does the bill look like in aggregate? The Transport Topics headline pegs the cost in billions. Industry trade groups have historically framed the total drag in that broad band, though precise annual figures are hard to pin down because detention is rarely broken out cleanly in carrier P&L statements.

Why is the fix so hard?

Three forces keep colliding.

• Contracts. Most detention pay sits inside freight contracts — shipper to broker, broker to carrier. The hourly threshold and dollar figure live in those documents. Renegotiating them lane by lane favors whichever party holds leverage on a given lane.
• Capacity cycles. Tight trucks push detention pay up. Loose trucks push it down. The current cycle — a multi-year freight downturn that has carriers chasing loads — has not been a buyer's market for detention raises.
• Regulation. Federal hours-of-service rules govern how long a driver can stay on duty. They do not directly pay detention. Some state jurisdictions have tried to mandate payment, with mixed enforcement. Earlier federal bills have stalled without committee movement.

For carriers, the per-load math is weak. Detention on a single load rarely moves the carrier's bottom line. For drivers, the per-shift math is personal. Lost time at one dock stacks up across a week. Lost home time stacks up across a career, and high driver turnover at large truckload fleets keeps reinforcing the cycle.

What would actually change the math?

Three items in the freight-policy playbook:

• A federal mandate or FMCSA rule requiring shippers and receivers to pay detention after a defined threshold, with a private right of action for drivers or carriers.
• Contractual standardization pushed by shipper-side procurement teams, raising the per-hour rate and tightening free-time windows.
• More facilities moving to scheduled-appointment systems, where detention times drop noticeably on the data the industry does track.

Each path faces headwinds. Congress has shown little appetite for new accessorial mandates. Procurement teams only push when capacity is tight. Facility rollouts are slow and capital-intensive.

What does this mean for shippers, brokers and forwarders right now?

The pressure point is dock discipline. Facilities running appointment systems with visible timing data pull average detention down sharply. Shippers that publish clear arrival windows and staff the dock accordingly get fewer contested detention invoices — and less accessorial chaos on the broker side.

Forwarders sitting between shipper and carrier hold leverage on contract terms during peak season and less during a soft market. The same dynamic that throttles contract rates throttles detention rates.

What's next?

It tracks capacity. If the freight market turns and trucks tighten, detention pay floats back into negotiations as a competitive lever. If the soft market runs another year, detention stays a friction line item neither side reopens.

Until something shifts, detention will keep draining carriers — and the fix, as Transport Topics frames it, stays hard.
