Difficulty: MediumMoving Hazards

As you approach a narrow side road to turn left, a long articulated lorry ahead signals left but swings out towards the centre line before making the turn. What should you do?

  1. A
    Pass the lorry on the left-hand side while there is sufficient space
  2. Stay well back behind the vehicle and allow it space to complete the manoeuvreAnswer
  3. C
    Flash your headlights to indicate that the lorry driver should proceed immediately
  4. D
    Accelerate quickly past the lorry on the right before it begins turning

Answer

Stay well back behind the vehicle and allow it space to complete the manoeuvre.
Long articulated vehicles require a wider turning circle and must often swing out across the road to stop the rear wheels mounting the pavement. Remaining well behind allows the driver adequate clearance and keeps your vehicle visible in their mirrors.

Step-by-Step Solution

1
Identify the moving hazard and the vehicle type ahead
Recognise that a long articulated vehicle needs extra road space to turn.
Articulated lorries have a large turning circle and an articulated pivot point that causes off-tracking.
2
Interpret the lorry driver's lane positioning
Understand that swinging right before turning left is necessary to prevent the trailer wheels from mounting the kerb.
The driver is not turning right; they are creating clearance for the rear of the vehicle.
3
Adopt a safe defensive following position
Hold back at a safe distance and wait until the junction is clear.
Remaining well back ensures you stay visible in the lorry mirrors and out of the trailer's swept path.
