Question

Difficulty: HardPre-Manoeuvre Observation

You are driving along a two-way suburban road and need to pull out to pass a large delivery lorry parked on your side of the carriageway. Before you signal and steer across the centre line, why is it essential to check your right-hand blind spot in addition to your mirrors?

  1. A
    To verify that pedestrians or workers are not about to emerge from around the front of the parked lorry
  2. B
    To maintain continuous visual focus on the parked vehicle ahead to ensure it does not reverse
  3. To detect any overtaking vehicle or motorcyclist that cannot be seen in your mirrorsAnswer
  4. D
    To check whether vehicles travelling directly behind you have seen the obstacle and slowed down

Answer

To detect any overtaking vehicle or motorcyclist that cannot be seen in your mirrors
Before signalling and moving out to pass an obstruction, drivers must check their mirrors and perform an offside blind-spot shoulder check. This confirms that no vehicle, motorcyclist, or cyclist has committed to overtaking from behind in the area not covered by mirrors.

Step-by-Step Solution

1
Assess the forward road and the obstruction
Identify that passing the stationary lorry requires crossing into the oncoming lane.
You must first ensure there is adequate road space and no oncoming traffic before planning to pull out.
2
Execute the Mirrors-Signal-Manoeuvre (MSM) routine
Check interior and right door mirrors to evaluate traffic approaching from behind.
Mirrors provide early awareness of following road users.
3
Carry out an over-the-shoulder right blind-spot check before signalling or steering
Confirm that no faster vehicle, motorcyclist, or cyclist has already begun overtaking in the unreflected blind area.
Mirrors have blind spots; moving out across the centre line without checking over your shoulder risks a collision with an overtaking road user.

Key Concept

Pre-manoeuvre observation requires checking both mirrors and the blind spot over the shoulder before altering course or overtaking an obstruction.
