Bulkhead (Headache rack) A strong wall-like structure placed at the front of a flatbed trailer (or on the rear of the tractor) used to protect the driver against shifting cargo during a front-end collision. A bulkhead may also refer to any separator within a dry or liquid trailer (also called a baffle for liquid trailers) used to partition the load.
