How to cut truck detention time at your dock

A driver pulls in at 7:55 for an 8:00 appointment. At 10:40 he's still in the yard, his dispatcher is on the phone, and next week an invoice for detention lands on your desk. Most small docks don't lose time on unloading itself. They lose it in the gaps: at the gate, waiting for a door, waiting for paperwork.

Know the clock you're on

In most freight agreements, the shipper or receiver gets two hours of free time from arrival before detention starts. That two-hour number is an industry convention, not a federal rule, so the real figure lives in the carrier contract or rate confirmation. Read yours. Some set it shorter, and the hourly rate after that varies.

It matters beyond the invoice. A study done for the Federal Motor Carrier Safety Administration found that drivers were held beyond two hours on roughly one in ten stops. Carriers remember which docks do that, and some quietly charge more to serve them.

Detention is rarely an unloading problem; it's a waiting problem you can see from the gate.

Fix the front door: appointments and check-in

1. Run real appointment windows. Give each carrier a slot, not "anytime before noon." Space them by how long your crew really takes per load, plus a buffer. If a 26-pallet floor load takes 90 minutes, don't book doors every hour.
2. Hold one slot open. A daily flex slot absorbs the early truck and the late one without pushing everyone back.
3. Check in without paper. A clipboard at the gate means retyping later and arguing about arrival times. Capture the vehicle number, transporter, order number and arrival time once, on a phone, when the truck reaches the gate. Our guide to running truck yard check-in without paper walks through the fields worth keeping.
4. Ask for documents before arrival. If the bill of lading or delivery order comes by email ahead of time, the gate becomes a quick match, not a reading session.

Assign doors before the truck stops

The worst minutes are the ones a driver spends parked while someone figures out where he goes.

• Pre-assign by appointment. Each slot gets a door and a crew the day before. The gate person says "Door 3" the moment the truck is checked in.
• Match the crew to the load. Floor-loaded bags need more hands than palletized freight. Put the bigger crew where the heavy load is.
• Use one status board. At Gate, On Dock, Working, Completed, Gate Out. When everyone sees the same board, nobody has to walk the yard to ask.
• Close paperwork at the door. Count, note shortages or damage, and sign before the truck leaves the door. Chasing a signature at the gate adds 20 minutes nobody budgets.

Measure dwell, then fix the worst hour

You can't cut what you don't measure. For one or two weeks, record three timestamps per truck: arrival at gate, start at door, and gate out. Then look at two numbers:

• Gate to door. Long waits here mean scheduling or door assignment problems.
• Door to gate out. Long times here mean crew size, paperwork or discrepancies.

Sort by hour of day. Most small docks find a single bad window, often the first hour or right after lunch, that creates most of the detention. Fix that window first: stagger breaks, add a hand, or move one appointment.

DockLedger is built for exactly this kind of yard. Log each truck from gate-in to gate-out with vehicle number, transporter and order number, allocate a dock, supervisor and labour gang, and move it through At Gate, On Dock, Working, Completed and Gate Out. The unload memo and shortage or damage issues sit on the same visit, and daily or monthly pending-vs-closed reports share as text in one tap. It's free, no subscription, and runs fully offline with no account.

Shave 30 minutes off the average truck this month, and the drivers will notice before your invoices do.
