Which post needs to be cut as part of a dash displacement?

• A. The A post
• B. The D post
• C. The B post
• D. The C post

Answer: (A)

Dash displacement relies on freeing the dash by cutting the front pillar that runs along the windshield—the A-pillar. This post anchors the dash to the vehicle’s frame, so cutting it allows the dash to be displaced forward, creating the space needed for access and removal of the patient. Cutting other pillars, like the B-pillar beside the door or the rear C- and D-pillars, won’t free the dash in the same way and can unnecessarily weaken the vehicle’s structure without achieving the desired forward movement of the dash.
