Once the dashboard has been displaced, what prevents it from settling back into place?

• A. The relief cut or notch
• B. The hydraulic shear used for displacement
• C. Cribbing inserted between the dashboard and the sill
• D. The high lift mechanical jack used for displacement

Answer: (C)

Stabilizing a displaced dashboard relies on a solid prop that prevents it from dropping back into place due to gravity and vehicle forces. Once the dash is moved, it tends to settle back toward its original position unless something holds it up. Cribbing placed between the dashboard and the sill provides a strong, load-distributing stop that keeps the dash in the displaced position. This creates the necessary space and keeps the dash from re-seating while you continue the extrication work. The other options don’t provide that reliable, physical stop. A relief cut or notch is for releasing pressure, not for holding components in a displaced position. A hydraulic shear is a tool used to create the initial displacement, not to maintain it. A high lift jack can move or support loads, but without cribbing it may shift or settle as you work.
