Question

Difficulty: MediumLane Discipline and Positioning

Traffic is queuing heavily approaching a lane closure where signs indicate 'Merge in Turn'. What should drivers do to maintain safe lane discipline and smooth traffic flow?

  1. A
    Move over into the open lane immediately and straddle the lane line to prevent other vehicles passing
  2. Use all available lanes until the merge point is reached, then take turns filtering into the open laneAnswer
  3. C
    Switch lanes continuously towards any temporary gap without checking vehicle blind spots
  4. D
    Accelerate aggressively along the closing lane to squeeze in front of large goods vehicles

Answer

Use all available lanes until the merge point is reached, then take turns filtering into the open lane.
Under Rule 134 of The Highway Code, in congested queuing traffic where lanes merge due to roadworks or lane reductions, drivers should use all available lanes and merge in turn where indicated. This practice maximises road capacity, shortens the overall queue length, and maintains a fairer, smoother flow for all road users.

Step-by-Step Solution

1
Assess traffic conditions and heed roadwork signs on approach
Recognise that traffic is slow-moving and queuing where a 'Merge in Turn' sign is present.
Rule 134 of The Highway Code recommends merging in turn when traffic is congested.
2
Maintain lane position and use both lanes up to the designated closure point
Queues are distributed evenly across all open lanes rather than extending excessively in one lane.
Merging prematurely leaves usable road space empty and creates longer tailbacks.
3
Filter into the open lane alternately with courtesy and care at the merge point
Vehicles from adjacent lanes alternate smoothly without confrontation or abrupt braking.
Cooperative merging keeps traffic moving steadily and safely through the restriction.
