You are travelling on a three-lane dual carriageway and plan to move from the middle lane into the left-hand lane. In which chronological order should you carry out these observation and signalling steps?
- 1Check the interior rear-view mirror to assess traffic following directly behind.
- 2Check the left exterior wing mirror to inspect traffic in the target lane.
- 3Glance over your left shoulder to check the blind spot area beside your vehicle.
- 4Signal left clearly once you have confirmed the manoeuvre is safe.
Answer
Check the interior rear-view mirror, check the left exterior wing mirror, glance over your left shoulder to check the blind spot, and finally signal left once confirmed safe.
Safe lane changing follows the standard Mirrors-Signal-Manoeuvre routine: start with the interior mirror for general awareness, check the relevant side mirror, perform a shoulder check into the blind spot to detect any unseen road users, and then indicate your intention.
Step-by-Step Solution
Key Concept
