If spray from other vehicles reduces visibility on a wet motorway, what is the recommended action?

• A. Reduce your separation distance
• B. Use dipped headlights
• C. Keep a two-second gap
• D. Remove spray-suppression equipment

Answer: (B)

When spray from other vehicles reduces visibility on a wet motorway, the priority is to make yourself as visible as possible and improve your own sightline. Using dipped headlights achieves this: they light your path without dazzling drivers ahead, and they make your vehicle more visible to others through the spray. Full beam would glare back at you and others in spray, making visibility worse, and simply trying to rely on following distance alone doesn’t directly address the visibility problem created by spray. So, switching to dipped headlights is the best action.
