Question

Difficulty: MediumLane Discipline and Positioning

While travelling on a suburban road, you notice a bus lane on your left whose operational hours have just ended. In what sequence should you carry out the necessary actions to move into the bus lane and maintain correct lane discipline?

  1. 1Check your interior mirror and left-hand door mirror to assess following and nearside traffic.
  2. 2Perform a left blind spot check over your shoulder for vulnerable road users such as cyclists.
  3. 3Apply the left indicator if a signal will benefit or inform other road users.
  4. 4Steer smoothly into the left-hand bus lane while maintaining a steady, appropriate speed.

Answer

Check interior and left door mirrors, perform a left blind spot check over the shoulder, apply the left indicator if helpful to others, and steer smoothly into the left-hand bus lane.
Under Rule 141 and Rule 137 of The Highway Code, drivers should keep to the left lane when not overtaking, including utilizing bus lanes when they are outside operational hours. Changing lanes requires the Mirrors-Signal-Manoeuvre (MSM) procedure: observing via interior and nearside mirrors, verifying the blind spot over the shoulder for vulnerable road users, applying a left signal if it benefits other road users, and finally steering smoothly into the newly available lane.

Step-by-Step Solution

1
Check the interior mirror and left exterior mirror.
The driver establishes awareness of vehicles behind and any road users approaching from the rear.
Observation is the essential first phase of the Mirrors-Signal-Manoeuvre (MSM) routine.
2
Check the left-hand blind spot over the shoulder.
The driver verifies that no cyclists, motorcyclists, or pedestrians are obscured by vehicle pillars.
Mirrors alone cannot capture all angles directly alongside the vehicle on the nearside.
3
Signal left if needed.
Following and nearby road users are informed in good time of the planned lane change.
Signals should be given clearly and only after verifying that the manoeuvre is safe to execute.
4
Steer smoothly across into the bus lane.
The vehicle adopts the correct normal driving position on the left without disrupting traffic flow.
Executing the manoeuvre smoothly preserves vehicle stability and adheres to Highway Code lane discipline.

Key Concept

Highway Code lane discipline dictates using the left-hand lane when clear, including bus lanes outside operational hours, executed via the standard Mirrors-Signal-Manoeuvre (MSM) routine.
