Detention
A fee charged when a truck is held at a shipper's or receiver's facility beyond the allotted free time for loading or unloading. Most carriers allow 1 to 2 hours of free time before detention charges begin, typically at $50 to $100 per hour. Detention is one of the most common accessorial charges and is a significant concern for carriers because it reduces their available driving hours.
Real-World Example
A driver arrives at a warehouse at 8:00 AM for a scheduled pickup but is not loaded until 12:30 PM. With 2 hours of free time, the shipper is billed 2.5 hours of detention at $75/hour ($187.50).
Why Detention Matters for Shippers
Freight pricing is rarely straightforward. Knowing how Detention works gives you leverage when negotiating rates, helps you spot hidden fees on invoices, and allows you to budget more accurately. Shippers who understand pricing mechanics are better equipped to compare quotes apples-to-apples and avoid costly surprises at delivery.
Common Questions About Detention
How is Detention calculated in freight shipping?
Detention in freight is typically calculated based on a combination of distance, weight, freight class, equipment type, and current market conditions. Additional factors like fuel surcharges, accessorials, and lane-specific supply and demand also play a role. Ask your broker for a transparent rate breakdown.
Can I negotiate Detention with my carrier or broker?
In most cases, yes. Understanding how Detention is structured gives you the knowledge to negotiate effectively. Volume commitments, flexible pickup windows, and consistent lane history all strengthen your negotiating position.
How can I reduce costs related to Detention?
Start by understanding exactly what goes into Detention, then look for optimization opportunities: consolidating shipments, adjusting pickup/delivery windows, improving packaging to reduce freight class, or committing to consistent volumes. A good freight broker will help you identify these savings.
