Difficulty: Very hardLane Discipline

You are driving in the right-hand lane (Lane 3) of a three-lane motorway, having just overtaken a long line of slower-moving traffic. The lanes to your left are now clear. According to proper motorway lane discipline, arrange the following actions in the exact chronological sequence required to safely return to the normal driving lane (Lane 1).

  1. 1Check your interior and left exterior mirrors to verify you are safely past the overtaken vehicles.
  2. 2Signal left and steer smoothly into the middle lane (Lane 2).
  3. 3Cancel your indicator and establish your vehicle's position in the middle lane.
  4. 4Conduct a fresh mirror check to assess the space and traffic flow in the left-hand lane (Lane 1).
  5. 5Apply a new left signal and move smoothly into the normal driving lane.

Answer

The correct sequence is to treat each lane change as a distinct manoeuvre: first check mirrors and move to the middle lane, cancel the signal and re-establish your position, then perform a new mirror check and signal before finally moving to the left-hand lane.
Proper lane discipline on a motorway dictates that you must not weave or cross multiple lanes in a single, sweeping movement. Each lane change must be treated as a distinct and separate manoeuvre involving its own MSM (Mirrors, Signal, Manoeuvre) routine. By cancelling the signal and pausing in the middle lane, you give yourself the opportunity to safely reassess the left-hand lane, which might contain joining traffic or a vehicle you had not previously noticed.

Step-by-Step Solution

1
Check mirrors for the middle lane (Lane 2).
You confirm it is safe to leave the right-hand lane (Lane 3).
You must always know the position of the vehicles you have overtaken before moving left.
2
Signal left and move to the middle lane.
Your vehicle enters the middle lane.
An indicator informs other road users of your immediate intention to change lanes.
3
Cancel the indicator and establish your position.
You are now travelling straight in the middle lane without an active indicator.
Leaving the signal on while crossing multiple lanes is dangerous. Each lane change must be treated as a separate manoeuvre.
4
Perform fresh mirror checks for the left-hand lane (Lane 1).
You confirm the left-hand lane is safe to enter.
Traffic conditions change rapidly; a new check ensures no vehicles are joining from a slip road or undertaking.
5
Apply a new left signal and move to the left-hand lane.
You safely return to the normal driving lane.
This completes the safe return to the left-hand lane, adhering to strict lane discipline rules.
