Pillar (car)


Pillars are the vertical or near vertical supports of a car's window area or greenhouse—designated respectively as the A, B, C or (in larger cars) D-pillar, moving from the front to rear, in profile view.
The consistent alphabetical designation of a car's pillars provides a common reference for design discussion and critical communication. As an example, rescue teams employ pillar nomenclature to facilitate communication when cutting wrecked vehicles, as when using the jaws of life.
