When following a large lorry on a wet road where spray reduces visibility, what should you do?

When following a large lorry on a wet road, particularly when spray is reducing visibility, dropping back until visibility improves is crucial for safety. This action allows for a greater stopping distance and enhances the driver's ability to see the road conditions ahead, any potential hazards, and the behavior of other vehicles.

Maintaining the same distance may not provide sufficient reaction time if the lorry suddenly stops, nor would it significantly improve visibility, as you would still be in the range of spray and decreased sightline. Speeding up to pass the lorry can also be risky, as it might lead to a loss of control on slippery surfaces or not provide enough time to react to changes in traffic as you maneuver around it. Following closely to reduce spray can create a dangerous situation, as it places the driver in a position where they have limited visibility and reaction time, increasing the risk of an accident. Therefore, the safest approach is to keep a greater distance until visibility is restored.
