A truck driver arrives on time at a distribution center. The paperwork is ready, the vehicle is in good condition, and another delivery is already scheduled. But then the waiting begins. Two hours pass. Then three. Sometimes four.
During that time, the driver isn’t making progress toward the next destination, isn’t completing the trip, and may be losing opportunities to accept additional loads. For an independent owner-operator, those delays can quickly become a financial problem.
In the United States, this situation is commonly known as driver detention time: the time truck drivers spend waiting at loading and unloading facilities, particularly when delays extend beyond the time reasonably required to handle freight.
The issue is not new. What makes it especially important is that federal transportation authorities also consider detention time a potential highway safety concern.
More Than $1 Billion in Lost Driver Income
The Federal Motor Carrier Safety Administration (FMCSA) has recognized the significant economic consequences of delays at shipping and receiving facilities.
According to a 2018 investigation by the U.S. Department of Transportation’s Office of Inspector General, referenced in FMCSA research, detention time was estimated to reduce annual earnings for drivers in the for-hire truckload sector by more than $1 billion.
The investigation also identified a concerning relationship between detention time and crashes. An additional 15 minutes of average detention time was associated with an estimated 6.2% increase in the expected crash rate.

These findings come from historical federal research, not from a new assessment of losses in 2026. Nevertheless, they illustrate the scale of a problem that remains the subject of federal investigation.
Small Trucking Companies May Feel the Impact More
The study also identified differences based on carrier size. Medium-sized trucking companies experienced excessive delays at approximately 19% of stops, compared with 9% for large carriers.
Although these figures come from earlier research and should not be interpreted as current 2026 measurements, they suggest that detention time may affect trucking operations differently depending on company size.
For owner-operators and small fleets, several hours of unproductive waiting can significantly affect trip profitability.
Fuel, insurance, equipment financing, permits, maintenance, and other operating expenses remain financial obligations whether the truck is moving or sitting at a loading dock.
Delays can also disrupt delivery schedules, interfere with future loads, and reduce the time drivers have available to operate their vehicles.
FMCSA Explores Up to Three Hours of Additional Flexibility
The issue has taken on renewed importance in 2026 as federal regulators continue examining potential changes to Hours of Service regulations.
The FMCSA has been preparing two pilot programs designed to evaluate alternative approaches to managing drivers’ working hours.
One initiative, known as the Split Duty Period Pilot Program, would examine whether participating drivers could pause their 14-hour driving window for qualifying non-driving periods of up to three hours.
Eligible periods could include certain waiting times at pickup or delivery facilities.
The objective is to determine whether greater flexibility could help drivers manage detention time, traffic conditions, and rest periods without compromising safety.
According to FMCSA information released in 2026, preliminary testing took place between May and July with nine drivers from three trucking companies.
The agency plans to use the findings to help prepare for broader pilot-program implementation in 2027.
Importantly, this does not mean that all truck drivers can currently pause their 14-hour duty window for three hours.
The initiative remains experimental and would apply only to eligible participants under the pilot program’s specific conditions.
Who Pays When a Truck Sits Idle?
In the American trucking industry, detention charges may be established through contracts or commercial agreements between carriers, brokers, shippers, and customers.
However, compensation arrangements vary. Not every trucking operation provides the same payment terms for excessive waiting.
It is therefore important to distinguish between the normal time required to load or unload a truck and additional delays that prevent a driver from continuing a trip.
Accurate records of arrival times, loading and unloading activity, and departure times can help carriers document detention and pursue compensation when permitted under their agreements.
FMCSA is also conducting research to better understand how frequently these delays occur and how they affect trucking operations.
One federal research initiative involves data from approximately 80 motor carriers and 2,500 drivers.
Detention Time Is Also a Highway Safety Issue
The consequences of detention do not necessarily end when a truck finally leaves the warehouse. A driver who has spent several hours waiting may face a reduced driving window, difficult delivery commitments, or the need to reorganize rest periods.
These circumstances can create operational pressure and potentially increase safety risks.
Federal researchers are examining the relationship between detention time, driver fatigue, operational performance, and crash risk. The challenge is to identify solutions that improve freight efficiency without creating additional pressure on drivers.
