The roof support on either side of a car's windshield is referred to as the ______.

• A. A-pillar
• B. B-pillar
• C. C-pillar
• D. Roof rail

Answer: (A)

The roof support on the sides of the windshield is called the A-pillar. These vertical members sit at the front corners of the roof, forming the sides of the windshield opening and carrying roof loads into the body. They play a key role in structural rigidity and rollover protection. The pillar between the front and rear doors is the B-pillar, the pillar behind the rear door is the C-pillar, and roof rails are the horizontal bars along the roof edge used for mounting accessories. So the side supports next to the windshield are the A-pillars.
