Difficulty: MediumNavigating Vehicle Blind Spots

You are driving a car and approaching a junction to turn into a side road. Why must you take extra care regarding the blind spots caused by your vehicle's windscreen pillars?

  1. A
    They only block your view of other road users if your exterior mirrors are incorrectly adjusted.
  2. B
    They only create a hazardous blind spot when you are following closely behind a large goods vehicle.
  3. They can completely obscure approaching vulnerable road users such as cyclists, motorcyclists, and pedestrians.Answer
  4. D
    They only obstruct your forward vision when you fixate solely on the road surface directly ahead.

Answer

Windscreen pillars can completely obscure approaching vulnerable road users such as cyclists, motorcyclists, and pedestrians.
Windscreen pillars (also known as A-pillars) support the roof and windscreen of the car. Due to modern safety standards, these pillars can be quite thick. At junctions and roundabouts, they can easily hide smaller road users such as pedestrians, cyclists, and motorcyclists who are approaching on a converging path. Drivers must actively move their head to look around both pillars to ensure the path is clear.

Step-by-Step Solution

1
Identify the physical obstruction created by vehicle windscreen pillars (A-pillars).
Recognised that the structural pillars framing the windscreen create blind spots in the driver's forward-diagonal field of vision.
Modern vehicle design includes thicker A-pillars for roll-over safety, which widens the angle of blocked vision.
2
Evaluate the risk this poses to different types of road users at junctions.
Understood that smaller, narrower road users (pedestrians, cyclists, motorcyclists) can easily fit entirely within the pillar's blind spot.
A cyclist or pedestrian moving on a converging path can remain hidden behind the pillar during the entire approach to a junction.
3
Determine the necessary defensive driving action to overcome this blind spot.
The driver must actively look around the pillars by moving their head before making turns or emerging at junctions.
Mirrors cannot show what is hidden behind the forward pillars, making physical repositioning and thorough scanning essential.
