Which post designation is located behind the rear doors or rear passenger compartment windows?

• A. A Posts
• B. B Posts
• C. C Posts
• D. D Posts

Answer: (C)

Understanding vehicle body post designations helps you quickly identify the structural members at the sides of a passenger compartment. The post located behind the rear doors or rear passenger window is the C-pillar. It runs along the rear portion of the roofline and supports the end of the roof and the rear window, contributing to the vehicle’s overall structural integrity in that area. In contrast, the A-pillar sits at the front edge by the windshield, and the B-pillar sits between the front and rear doors. Some vehicles also have a D-pillar at the very rear, but the post behind the rear doors specifically is the C-pillar.
