Every moment a truck sits idle, it’s not earning. When it’s dwell time, it’s costing you money, and that compounds quickly for both carriers and shippers.
Excessive dwell time can put a big dent in your margins and throw your logistics off schedule. So, let’s explain dwell time trucking impacts and strategies to reduce its impact.
What Dwell Time Means in Trucking and Shipping
What is dwell time in trucking? Dwell time is the time your trucks, trailers, or shipments spend at a location, from the time they arrive until they leave. That includes the time waiting in the yard before dock space opens up and the actual unloading or loading.
Dwell time is similar, but shouldn’t be confused with demurrage vs. detention time. Detention time is what happens when trucks or containers have to wait beyond the agreed-upon window. In standard contracts, that’s typically about two hours. Beyond that, carriers typically charge an extra fee for detention time. Similarly, demurrage fees apply if your goods have to sit inside the port terminal too long, past your allotted “free time.” For logistics managers handling ocean or intermodal freight, understanding detention time and demurrage costs and causes is crucial to avoid excess costs.
Common Causes of Dwell Time
There are several common reasons why dwell time happens. You might expect brief waiting periods, but sometimes carriers or facilities have inefficient operations or poor scheduling that are the culprit. Common causes of dwell time in yard operations include:
- Poor dock scheduling leading to arrival congestion: Multiple trucks arriving simultaneously can overwhelm available dock capacity and create lengthy queues.
- Insufficient warehouse labor during peak periods: Staffing shortages can slow loading and unloading activities, increasing truck wait times.
- Manual or inefficient check-in and paperwork processes: Paper-based workflows often create bottlenecks before trucks can access docks.
- Facility layout issues that slow loading and unloading: Poorly organized staging areas, traffic flow constraints, and dock placement can extend handling times.
- Lack of visibility into truck arrival times: Facilities that cannot accurately anticipate arrivals struggle to allocate resources effectively.
- Miscommunication between carriers and shippers on appointment windows: Scheduling or routing errors can result in trucks arriving too early or too late.
In short, anything that leads to congestion creates delays, and it can back up your overall logistics plan, causing downstream delays.
The Cost of Dwell Time for Carriers and Shippers
According to the Federal Motor Carrier Safety Administration (FMCSA), average dwell time truck statistics show that about 10% of stops include 3.4 hours of dwell time (1.4 hours of which becomes detention time). That costs the logistics industry as much as $1 billion a year. That’s bad enough, but these delays can also ripple across your entire network.
Dwell Time Costs for Carriers
- Reduced asset utilization: Trucks generate revenue when moving freight, not when sitting idle.
- Lost driver productivity: Excessive wait times consume valuable hours of service that could otherwise be spent transporting loads.
- Lower trailer utilization: Delays prevent equipment from being redeployed efficiently across routes.
- Higher operating costs: Fuel consumption, labor expenses, and administrative overhead continue even when trucks are not moving.
- Safety: Per FMCSA, an increase of 15 minutes in average dwell time increases the expected rate of accidents or crashes by more than 6%.
Dwell Time Costs for Shippers
- Increased detention fees: Extended wait times often result in additional charges from carriers.
- Higher transportation rates: Carriers frequently factor chronic delays into future pricing agreements.
- Reduced carrier availability: Facilities known for excessive delays may become less attractive to preferred carriers.
- Delivery disruptions: Delays at one facility can affect subsequent shipments and customer commitments.
- Weaker performance metrics: Excessive dwell time can negatively impact OTIF performance and broader service objectives.
Tracking dwell time becomes crucial as it’s a leading indicator of supply chain challenges that impact your costs and your ability to serve your customers.
5 Strategies to Reduce Dwell Time in Trucking
Reducing dwell time requires coordinated effort across both carrier and shipper operations.
1. Implement Appointment-Based Dock Scheduling
Structured appointment scheduling helps distribute truck arrivals more evenly throughout the day. This helps facilities allocate dock capacity based on demand. In turn, this improves resource planning, reduces waiting times, and creates more predictable workflows for both carriers and warehouse personnel.
2. Adopt Drop-and-Hook Where Possible
Drop-and-hook operations allow drivers to exchange trailers instead of waiting for live loading or unloading. This significantly reduces freight idle time and improves equipment utilization. While not practical for every operation, drop-and-hook programs can dramatically improve turnaround time in high-volume environments.
3. Streamline Check-In and Documentation
Manual paperwork and gate processing often create delays before loading activities even begin. Implementing digital check-in systems, automated workflows, and electronic documentation reduces friction at entry and exit.
4. Improve Facility Layout and Staging
Physical facility design plays a major role in transportation efficiency.
Clearly designated traffic patterns, optimized dock assignments, and pre-staged loads can significantly reduce loading and unloading delays. Small improvements to facility organization often generate measurable reductions in average dwell time truck performance metrics.
5. Leverage Yard Management Technology
Implementing yard management systems can make a big difference. A YMS helps monitor activity in the yard, from arrivals, status, dock availability, and movements through the facility. You know exactly where everything is at any time and where it should be. So, when there’s congestion, you have the real-time data to make better decisions to reduce dwell time. Surgere’s Yard Management software cis a good example, and can help you maximize your transportation schedules with real-time data about the location and status of all of your assets.

Most dwell time problems share a common root cause: a lack of visibility. When transportation teams can’t see where trucks, trailers, and assets are located in real time, delays can start to stack up and dwell time increases.
Surgere helps organizations close this visibility gap through IoT-powered tracking, producing the real-time transportation visibility you need to monitor your entire supply chain. You can track your assets at each step of the journey and make better decisions about ldwell time ogistics.
You get the data you need to:
- Identify dwell time shipping patterns.
- Monitor carrier and facility performance.
- Find operational bottlenecks.
With continuous visibility, you can make real-time adjustments as needed to improve operations and spot trends you might otherwise miss.
