Difficulty: MediumMoving Hazards

While following a long articulated vehicle approaching a tight left-hand turn, you notice the driver signalling left but swinging out towards the centre line. What should you do?

  1. A
    Move into the gap on the left-hand side to pass before the vehicle turns
  2. Stay well back and allow the vehicle sufficient room to complete the turnAnswer
  3. C
    Flash your headlights to signal the driver to complete the turn
  4. D
    Move into the adjacent lane to overtake without checking your blind spots

Answer

Stay well back and allow the vehicle sufficient room to complete the turn.
Long articulated vehicles require extra road space to navigate tight corners. When turning left into a narrow road, the driver must often swing wide to the right so that the rear trailer wheels do not mount the kerb. Drivers following behind should remain well back to give the lorry room to manoeuvre and keep out of its blind spots.

Step-by-Step Solution

1
Observe the vehicle's left-turn indicator and recognise why it has swung out towards the centre line
Understands that the driver is creating a wider turning arc for the trailer rather than turning right
Long vehicles require additional road width to prevent the rear wheels cutting across the kerb or pavement
2
Assess the potential hazards around the lorry, including blind spots and the closing gap on the left
Recognises that the temporary gap on the inside is an active danger zone where the trailer will track
Undertaking or crowding the lorry creates a severe risk of being side-swiped or trapped
3
Drop back and maintain a safe following distance until the manoeuvre is complete
Leaves the junction clear for the vehicle to complete the turn safely while keeping clear visibility
Defensive driving requires giving large moving vehicles the space they need to negotiate tight junctions
