This guide explains the issue in simple terms, what a carrier can do today, and where RGI Dispatch can offer practical support.
Why accessorial terms matter
A truck can arrive on time and still lose working hours at a shipper or receiver. Extra waiting may affect the next booking, fuel consumption and driver schedules. Knowing the terms before dispatch can prevent misunderstandings.
Detention: waiting beyond agreed free time
Detention generally refers to compensation that may be available after a truck waits beyond the agreed free period for loading or unloading. The free time, rate, documentation and eligibility depend on the broker-carrier agreement or rate confirmation; payment is not automatic.
Layover: an extended delay
Layover typically describes a delay that keeps the truck waiting for a longer period, often overnight. It is not interchangeable with detention in every contract. Ask what event qualifies and who approves the payment.
TONU: truck ordered not used
TONU may apply when a truck is dispatched for a load that is canceled after the carrier has committed or started moving, depending on the terms. Confirm the cancellation timing, proof needed and any agreed compensation. Never assume a standard flat amount applies everywhere.
What to record at the dock
Keep arrival and departure timestamps, appointment details, check-in records, written messages, bills of lading and any shipper or receiver notes. Use accurate records, and report a delay promptly to the broker. Follow any tracking procedure required under the load agreement.
What to check on the rate confirmation
Before starting, read the pickup and delivery appointments, free-time definitions, detention request deadlines, payment eligibility, layover conditions and cancellation policy. If wording is unclear, ask the broker to clarify in writing.
How RGI Dispatch helps
We help coordinate appointment communication, remind carriers what documentation may be needed, and raise accessorial questions with the broker. Actual eligibility and payment remain subject to the signed terms and broker approval.
