What is out of service?
Also called OOS, out-of-service order
An out-of-service order stops a driver or a vehicle from operating until the problem that caused it is corrected. It is issued at the roadside during an inspection, or against an entire company for serious regulatory failures.
A vehicle order covers a mechanical defect serious enough that the truck may not move until it is repaired. A driver order covers the person, commonly for exceeding driving-hour limits or lacking a valid licence, and the driver may not continue even in a sound vehicle.
An order against a whole company is far more serious and shuts down its operations entirely rather than one truck or one driver.
Roadside inspection results, including whether anything was placed out of service, become part of the company's safety history.
What it means on a dispatch desk
For a dispatch desk the practical consequence is a load already committed and a truck that cannot legally finish it, which is a conversation with a broker rather than a maintenance problem. A carrier whose trucks are repeatedly placed out of service is a carrier whose loads will repeatedly need recovering, and that cost lands on whoever dispatched them.
