# Swap body

> A swap body is a standardised, detachable freight container that can be moved between trucks and trailers, allowing a vehicle to drop one load and pick up another quickly.

Swap bodies decouple the cargo unit from the vehicle: a body can be loaded while detached, then mounted on a chassis only when ready to move, improving asset utilisation. They are common in European road and combined transport.

A TMS that treats trailers, containers, and swap bodies as independent, trackable equipment can attach and detach them from vehicles during trips and apply the correct capacity and stacking rules.
