Accessorials explained: detention, TONU, layover, lumper

Short answer. Accessorials are extra charges on a load: detention (waiting beyond the free time, usually 2 hours), layover (a full day lost), TONU (truck ordered, not used), lumper (paid unloading) and extra stops. They are paid only with written confirmation from the broker, on the rate confirmation, a revised RC or an email.

The main accessorials

DetentionWaiting beyond free time (usually 2 h) at shipper or receiverPer hour after free time (~$40–75/h, per the RC)In/out times on BOL/POD or ELD + broker approval
LayoverThe truck sits a full day because of the customerFlat per day (~$150–300)Written broker confirmation

TONULoad cancelled after the truck left or arrivedFlat (~$150–250)Cancellation email + TONU confirmation
Extra stopAdditional pickup or deliveryPer stop (~$50–100)On the RC or a revised RC

Amounts vary by broker and are set on each rate confirmation.

How to calculate detention

Arrived 08:00, left 13:00 = 5 hours. Free time 2 hours = 3 billable hours. At $50/hour = $150. Many rate cons require the driver to be on time for the appointment; a late driver usually loses detention.

The rule that gets accessorials paid

No written confirmation, no accessorial. The right flow: the driver updates the dispatcher in real time; the dispatcher notifies the broker during the wait; the broker approves by email or revised RC; accounting attaches the proof to the invoice, on a separate line.

In one fleet, almost 35% of detention requests were rejected for lack of confirmation. A simple email template sent as soon as the free time ended cut rejections sharply.

Questions

What does TONU mean?

Truck Ordered, Not Used: a fee paid when a broker cancels a load after the truck was dispatched or arrived.

How long is free time before detention?

Usually 2 hours at each stop, but the rate confirmation decides.

Is detention paid to the driver?

Often yes. Many companies pay drivers detention, layover and extra-stop pay. If accounting does not collect it from the broker, the company pays it out of pocket.
