Difficulty: Very hardHazard Perception and Anticipation

You are driving along a busy urban high street with a continuous line of parked cars on your left. Ahead, an oncoming Large Goods Vehicle (LGV) flashes its headlights and begins to move across into your lane to bypass a stationary delivery van on its side of the road. Simultaneously, you notice a slight movement in the shadows between two of the parked cars on your left. What is the safest anticipatory driving plan in this situation?

  1. A
    Focus your attention entirely on the LGV to judge its speed and trajectory, as a heavy vehicle crossing into your lane is the most critical immediate threat.
  2. B
    Maintain your current speed but move closer to the parked cars, assuming the LGV driver flashed their headlights to acknowledge your priority.
  3. Slow down and prepare to stop well back, dividing your scanning between the LGV's position and the gaps between the parked cars on your left.Answer
  4. D
    Move as close as possible to the parked cars to maximize clearance for the LGV, as the stationary vehicles provide a safe buffer from the pavement.

Answer

The correct response is to slow down and prepare to stop well back, actively dividing your attention between the LGV and the gaps between the parked vehicles.
In complex, multi-hazard scenarios, the safest approach is always to reduce speed and prepare to stop. Drivers must continuously scan the environment holistically rather than fixating on a single obvious threat. A safe clearance must be maintained from parked cars, as any movement between them strongly indicates a hidden pedestrian. Furthermore, the Highway Code dictates that flashing headlights only warn of a vehicle's presence and must never be interpreted as a green light to proceed.

Step-by-Step Solution

1
Assess the multiple developing hazards in the environment.
Identified the LGV entering the lane, the flashing headlights, and the movement between parked cars.
Expert hazard perception requires scanning the entire scene rather than fixating on the most obvious visual stimulus.
2
Interpret the LGV driver's flashing headlights correctly.
Recognized that the flashing headlights merely indicate the vehicle's presence, not a guarantee of priority.
The Highway Code explicitly states that flashing headlights should never be taken as a signal to proceed or that the other driver is giving way.
3
Determine the appropriate spatial management strategy.
Decided to reduce speed and prepare to stop instead of altering lateral positioning towards the parked cars.
Moving closer to parked cars eliminates the vital 'door-width' safety clearance needed to react to sudden pedestrian movements or opening doors.
4
Execute the safest anticipatory plan.
Slowing down while continuously scanning both the oncoming LGV and the left-hand static hazards.
This maximizes time to react to the highest-probability hidden threat (a pedestrian) while safely managing the known threat (the LGV).
