Windscreen pillars are a critical component of vehicle design for many reasons – primarily design and safety.

These structural support frame the windscreen and connects the roof of the vehicle to the rest of the body.

Although they keep the structural integrity of the vehicle, they can also create blind spots for drivers.

As modern car designs evolve over time, so do engineering considerations around windscreen pillars.

The article provides you with the know how about these structures – and how they can impact your driving.

What are windscreen pillars?

Windscreen pillars are the vertical support structures that are located on either side of the vehicle’s windscreen.

They are connected to the main body and roof of the vehicle.

Windscreen pillars are vital for structural integrity, aerodynamics, and safety – and also play a role in housing important features, such as wiring, sensors, and even airbags.

Although they are undoubtedly important, they can also provide challenges with visibility through blind spots.

Can windscreen pillars cause accidents?

Yes, windscreen pillars can play a role in road accidents primarily due to the blind spots that they create.

These pillars can obstruct a driver’s view of other road users (vehicles, cars, pedestrians, etc), and other potential obstructions when turning.

This momentary loss of vision can be a factor in a collision – as the driver is unable to notice the hazard in enough time to brake.

While essential for safety and structural integrity, bulky and poorly designed windscreen pillars can compromise situational awareness.

How to avoid an accident

To avoid potential accidents caused by blind spots created by windscreen pillars, here are some practical tips:

Look and lean – move your head to check the blind spot before carrying out your manoeuvre
Slow down – this will give you more time to assess the situation
Keep windscreen clear – regular cleaning is essential for safety
Modern tech – newer vehicles have add ons that can help you with monitoring a blind spot

Pillar A

The A pillar is the one at the front of the car that frames the car windscreen and connects the body of the vehicle to the roof. It can also house important technology and safety features.

Pillar B

This is the section between the front and rear doors for the vehicle – or the pillars between the front car doors and the back ones. These are important for the structure of the vehicles and can also keep important safety items in them.
