Question

Difficulty: MediumFollowing Distances and Tailgating

You are driving behind a large articulated lorry on a wet single-carriageway road. What is the main reason for staying well back rather than following closely?

  1. A
    To stay sheltered from headwinds and reduce your vehicle's fuel consumption
  2. B
    To position your vehicle within the driver's blind spot to avoid headlight reflection
  3. To get a clearer view of the road ahead and increase your stopping marginAnswer
  4. D
    To maintain the standard two-second gap without adjusting for wet road conditions

Answer

To get a clearer view of the road ahead and increase your stopping margin
Staying well back from a large vehicle dramatically widens your forward field of vision, allowing you to see oncoming traffic, road signs, and emerging hazards. It also ensures you maintain the required four-second gap for wet conditions and reduces the amount of spray hitting your windscreen.

Step-by-Step Solution

1
Identify the vehicle type and weather conditions
Following a large goods vehicle on a wet road surface
Large vehicles obstruct forward vision, and wet conditions double stopping distances
2
Apply the appropriate safety gap rule
Increase following distance to at least four seconds or more
Doubling the separation distance compensates for reduced tyre grip and spray
3
Evaluate the visibility benefit of dropping back
Expanded forward sightlines and visible mirrors for the lorry driver
Staying further back allows the driver to see past the lorry to anticipate oncoming hazards and road layout

Key Concept

Increasing following distances behind large vehicles in wet conditions to maximise visibility and stopping buffer
