Difficulty: MediumLane Discipline and Positioning

After completing an overtaking manoeuvre on a three-lane dual carriageway, you observe that the nearside (left-hand) lane ahead is completely clear of traffic. What should you do to maintain correct lane discipline?

  1. A
    Remain in the middle lane to avoid weaving between lanes if further traffic appears later
  2. Check your mirrors and blind spot, then return safely to the left-hand laneAnswer
  3. C
    Steer sharply into the left lane as soon as your front bumper passes the overtaken vehicle
  4. D
    Move across into the right-hand lane and accelerate up to the maximum speed limit

Answer

Check your mirrors and blind spot, then return safely to the left-hand lane
Under UK Highway Code Rules 137 and 138, you should always drive in the left-hand lane (Lane 1) whenever the road ahead is clear. Middle and right-hand lanes are designated purely for overtaking slower-moving traffic or positioning for upcoming right turns. Once an overtaking manoeuvre is completed safely, you must check your mirrors, check blind spots, signal if necessary, and move back into the left-hand lane.

Step-by-Step Solution

1
Assess the position of the overtaken vehicle and the road ahead
Confirm that the left-hand lane is clear and that there is adequate safety clearance ahead of the overtaken vehicle
You must ensure you do not cut across the path of the vehicle you just passed
2
Carry out mirror and blind spot observations before signalling and moving over
Safely position the vehicle back into the left-hand lane (Lane 1)
Highway Code Rules 137 and 138 mandate that drivers must always return to the left-hand lane once overtaking is complete
