The _________ are typically welded to the floor pan, pillars, and quarter panels.

• A. Floor Rail
• B. Rocker Panel
• C. Sill Plate
• D. B-Pillar

Answer: (B)

Rocker panels are the lower side body members that run the length of the vehicle between the front and rear wheelhouses. They’re welded to the floor pan, to the vertical pillars (like the B-pillar), and to the quarter panels to form a continuous structural path. This connection helps transfer loads between the floor and the side of the vehicle and adds lateral stiffness, which is why rocker panels are the panels that are typically welded to those components. The other options refer to parts with different locations or roles: floor rails are part of the floor structure, sill plates are interior door thresholds, and the B-pillar is a vertical support member rather than a long side member.
