A-Pillar
The A-pillar is the roof support on each side of the windscreen, between the windscreen and the front door.
What is A-Pillar?
It is a key part of the body structure in a rollover or frontal crash. Wide pillars can hide pedestrians and cyclists at junctions. Curtain airbags often run up along the A-pillar trim. Narrow A-pillars and split pillars with small extra windows are used on some cars to improve the view.
How it works
High-strength steel sections form a hollow pillar that transfers loads from the roof to the floor.
Why it matters for your car
Lean forward or move your head at junctions to look around it. Damage to the A-pillar after a crash is a serious structural repair.
