Where should the A post be cut during a dash displacement?

• A. At the top where it meets the roof
• B. In the middle of the post
• C. At the base of the B post
• D. At the bottom where it meets the sill or floor of the vehicle

Answer: (D)

When displacing the dash, the goal is to free the interior while keeping the vehicle’s structure as stable as possible. The A post is a main vertical member that helps support the roof, so choosing a cut location that yields a controlled release is crucial. Cutting the A post at the base where it meets the sill or floor creates a hinge-like point that can release smoothly without compromising the roof or the upper portion of the post. This keeps the top portion intact to maintain roof integrity and helps the dash move out of the way predictably. Cutting higher up the post or in the middle risks weakening or deforming the pillar, which can lead to uncontrolled movement, greater intrusion, or damage to surrounding structures. So the bottom location—where the A post meets the sill or floor—is the safest and most effective spot for this maneuver.
