Question

Difficulty: MediumLarge Goods Vehicles (LGVs)

You are driving behind an articulated Large Goods Vehicle (LGV) on a single-carriageway road. The lorry indicates left to enter a narrow commercial entrance, but the driver steers towards the centre line before making the turn. In what sequence should you carry out the following actions to manage this situation safely?

  1. 1Check your interior and door mirrors to assess the traffic following behind you.
  2. 2Ease off the accelerator to drop well back and stay visible in the lorry's exterior mirrors.
  3. 3Hold your position behind the lorry without trying to undertake or squeeze past on the left.
  4. 4Proceed along your route only after the lorry has completely cleared the entrance and the road ahead is unobstructed.

Answer

Check your mirrors to assess following traffic, ease off the accelerator to drop back into the lorry driver's mirror view, hold your position behind without attempting to pass on the left, and proceed only once the lorry has fully completed its turn and the road is clear.
When following a long vehicle turning into a narrow entrance, standard defensive driving requires checking mirrors first to monitor following traffic, increasing separation distance to remain visible in the lorry's mirrors, waiting patiently behind while the trailer completes its sweeping arc, and proceeding only when the road ahead is completely clear.

Step-by-Step Solution

1
Check interior and door mirrors.
Full situational awareness of following road users before adjusting speed.
Applying the Mirrors-Signal-Manoeuvre routine ensures you do not surprise trailing vehicles when you begin slowing down.
2
Drop well back by easing off the accelerator.
Expanded forward visibility and positioning outside the LGV's immediate blind spots.
Large vehicles block forward view; hanging back ensures the lorry driver can see you in their side mirrors and gives you a safety buffer.
3
Hold back patiently behind the turning vehicle.
Avoidance of the dangerous nearside blind spot and trailer swept path.
When an LGV swings right to turn left, the gap on the left is deceptive; the trailer will track tightly across that space as the vehicle turns.
4
Proceed once the manoeuvre is finished and the road is clear.
Safe continuation of your journey without risk of collision.
Long articulated vehicles take considerable time to complete tight turns and clear the carriageway.
