What is the term for short lengths of sturdy timber used to vertically stabilize a vehicle?

The term for short lengths of sturdy timber used to vertically stabilize a vehicle is "cribbing." This method involves stacking timbers in a manner that creates a stable support for the vehicle, preventing it from shifting or rolling over during rescue operations or while it is being worked on. Cribbing is essential in various scenarios, particularly in vehicle extrication, as it ensures the safety of both the vehicle being stabilized and the personnel involved in the rescue effort.

Chocks can also be used to stabilize vehicles, but they typically refer to wedges placed against the wheels to prevent movement rather than vertical stabilization. Shoring generally refers to supporting structures, such as walls or roofs, rather than vehicles specifically. Wedges are inclined planes that can secure objects but are not the primary choice for the vertical stabilization of vehicles. Thus, cribbing is the most appropriate term regarding the context of stabilizing vehicles.
