Question

Difficulty: Very hardNavigating Vehicle Blind Spots

You are driving a Large Goods Vehicle (LGV) and intend to turn left at a tight urban junction. To negotiate the corner without the rear wheels mounting the pavement, you have positioned the vehicle slightly to the right of your lane. How must you manage your blind spots during this specific manoeuvre?

  1. Continuously monitor your left-hand mirrors throughout the entire manoeuvre, actively checking for cyclists who may filter into the large near-side blind spot created by your wide road position.Answer
  2. B
    Perform a comprehensive left mirror check before moving, but once the vehicle is in motion, maintain your focus exclusively ahead to ensure the cab clears oncoming traffic.
  3. C
    Rely entirely on the vehicle's acoustic warning system and sensors to alert you to pedestrians or cyclists in your blind spot, as direct visual checks become severely restricted once the cab pivots.
  4. D
    Assume that moving the cab to the right automatically closes off the space on the left, making it physically impossible for cyclists to enter your near-side blind spot while you turn.

Answer

You must continuously monitor your left-hand mirrors throughout the entire manoeuvre, actively checking for cyclists who may filter into the large near-side blind spot created by your wide road position.
The correct answer emphasizes the absolute necessity of continuous visual monitoring using left-hand mirrors. When an LGV swings right to turn left, it opens a large gap on the near-side. Cyclists may mistakenly believe the vehicle is turning right or leaving them room to pass straight ahead. Because the blind spot is vast and the situation changes rapidly as the vehicle pivots, continuous mirror checks are the only way to detect a vulnerable road user before the trailer's rear wheels track across their path.

Step-by-Step Solution

1
Analyze the hazard presented by the LGV's road position.
Moving to the right to prepare for a left turn creates a large, inviting gap on the vehicle's left (near-side).
Vulnerable road users, particularly cyclists, may misinterpret this road positioning as an opportunity to filter up the inside of the vehicle.
2
Identify the specific blind spot risk associated with the vehicle.
The sheer length and height of the LGV create a massive near-side blind spot that can completely hide entire vehicles, cyclists, and pedestrians.
The driver's direct field of vision is severely restricted by the cab structure and the length of the trailer body.
3
Determine the correct observational procedure for the driver.
The driver must use continuous mirror checks on the left side before and throughout the entire turning process.
Because the blind spot is vast and dynamic, a single check before turning is insufficient to guarantee safety as cyclists can quickly move into the danger zone.
