Question

Difficulty: EasyAwareness and Observation

You are driving on a dual carriageway and intend to change lanes to the right. After checking your mirrors and signalling, which action should you take immediately before moving across?

  1. A
    Assume the lane is clear if your mirrors appear empty
  2. B
    Flash your headlights to claim priority over approaching vehicles
  3. Check your right-hand blind spot with a quick sideways glanceAnswer
  4. D
    Fix your gaze strictly on the road directly ahead without further checks

Answer

Check your right-hand blind spot with a quick sideways glance
Before steering across to change lanes, a quick sideways glance over the shoulder is essential to check the blind spot. Even properly adjusted mirrors leave areas beside and slightly behind the vehicle hidden, where overtaking traffic or motorcycles may be travelling.

Step-by-Step Solution

1
Assess the observation routine required before changing lanes on a multi-lane carriageway
Recognise that vehicle mirrors do not provide a complete view of the road beside you
All vehicles have blind spots where other road users can be hidden from mirror view
2
Determine the final visual safety check before commencing the lane change
Perform a quick glance over the right shoulder into the blind spot area
This confirms no vehicle or motorcyclist is positioned alongside before steering into the adjacent lane
