Which term refers to the vertical posts between the front and rear windows, typically labeled A, B, and C?

• A. Rocker panel
• B. A, B, C posts
• C. Roof rail
• D. Nader side

Answer: (B)

These vertical side members are the vehicle pillars—the front, middle, and rear pillars that frame the cabin and support the roof. In rescue training they’re specifically called A-, B-, and C-pillers (often spoken as posts). This terminology directly describes their position between the front and rear windows, which is why this phrase is the best fit. Knowing these pillars helps you plan stabilization and entry, since they define the passenger compartment and influence where you cut or pry. The other terms refer to different parts of the vehicle: rocker panel is along the bottom edge under the doors, roof rail runs along the roof, and “Nader side” isn’t the standard term for these posts.
