  1. A
    Continue overtaking in the middle lane and change lanes only when you reach the 100-yard countdown marker
  2. Plan ahead and safely move across into the left-hand lane well before reaching the countdown markersAnswer
  3. C
    Move into the left-hand lane immediately by cutting into the safety space ahead of a large goods vehicle
  4. D
    Stay in the middle lane and brake firmly on the carriageway until traffic clears on the left

Answer

Plan ahead and safely move across into the left-hand lane well before reaching the countdown markers.
According to Highway Code Rule 272, drivers should watch for advance warning signs and move into the left-hand lane well before reaching their exit. Getting into the left lane in good time allows the driver to prepare for the countdown markers (300, 200, and 100 yards) and transition smoothly into the deceleration slip road without braking on the main carriageway or making sudden multi-lane manoeuvres.

Step-by-Step Solution

1
Observe the advance direction sign positioned one mile before the junction.
Early awareness of the upcoming exit is established, prompting immediate forward planning.
Highway Code Rule 272 requires drivers to watch for early signage and prepare to exit in plenty of time.
2
Use mirrors to assess traffic in the left-hand lane and identify a safe, generous gap.
A safe manoeuvre path is confirmed without infringing on the following distances of other vehicles.
Thorough observation and blind spot awareness prevent cutting off other drivers or creating sudden hazards.
3
Signal your intention to move left in good time and smoothly transfer to the left-hand lane.
The vehicle is stably positioned in the left lane well ahead of the 300, 200, and 100-yard countdown markers.
Being established in the left lane allows a seamless transition into the deceleration lane without braking on the carriageway.
