As we covered in the past, a TONU, short for Truck Order Not Used, is an accessorial charge paid to a driver for their time when a load is canceled on them for a variety of reasons. The load could be delayed until a later day, two drivers could be double booked on the same load, or perhaps the shipment was canceled altogether by the shipper. Regardless of the circumstances, the TONU is intended to compensate the driver for their time spent on the load even though it wasn’t picked up.
