What is bobtail?
Bobtailing is driving a tractor with no trailer attached at all. It is distinct from deadhead, which is pulling an empty trailer.
A tractor bobtails between dropping a trailer and picking up the next one, on the way to or from a repair shop, or heading home at the end of a run.
A bobtailing tractor handles differently from a loaded one. Most of the braking weight is gone from the rear axles, so stopping distances and wet-road behaviour change, which is why it carries its own insurance category.
What it means on a dispatch desk
Worth knowing as vocabulary rather than as a decision. Where it matters operationally is insurance: bobtail coverage is a separate line, and a carrier who has let it lapse is exposed on exactly the short unpaid trips nobody is thinking about.
