You are driving along a three-lane motorway in dense fog at night. You observe white reflective studs to your left and amber reflective studs to your right. Which lane are you travelling in?

  1. A
    The left-hand lane
  2. The right-hand laneAnswer
  3. C
    The middle lane
  4. D
    An exit slip road

Answer

The right-hand lane
On UK motorways, amber reflective studs mark the edge of the carriageway adjacent to the central reservation (on the driver's right), while white studs mark the boundaries between individual traffic lanes (on the driver's left). Therefore, travelling with white studs to the left and amber studs to the right places the vehicle in the right-hand lane.

Step-by-Step Solution

1
Identify the meaning and placement of amber reflective studs on a UK motorway
Amber studs are placed exclusively along the right-hand edge of the carriageway, adjacent to the central reservation.
Highway Code Rule 132 defines amber studs as marking the reservation boundary on the offside.
2
Identify the meaning and placement of white reflective studs
White studs are used between individual lanes to mark lane boundaries.
White studs divide lanes across the main carriageway.
3
Combine the relative positions of the observed studs to deduce lane position
Having white studs on the left (lane boundary) and amber studs on the right (central reservation) places the vehicle in the outermost right-hand lane (Lane 3).
Only the right-hand lane sits directly between a lane boundary line and the central reservation.
