Which factor directly reduces visibility when driving fast in rain?

• A. More spray will be thrown up
• B. Windscreen wipers obstruct your view
• C. Headlights will dazzle you more easily
• D. Drivers bunch together when it's raining

Answer: (A)

When you’re driving fast in rain, the main thing that cuts your visibility is the spray kicked up by tyres. Water and spray from the road and from other vehicles create a curtain in front of your windscreen, making it hard to see far ahead or to judge distances. This direct spray layer is harder to clear quickly than rain on the glass, so visibility drops noticeably. Windscreen wipers don’t obstruct your view; they remove rain to improve visibility, so they aren’t the cause. Headlights can create glare in certain conditions, but they don’t directly reduce visibility the way spray does. And drivers bunching together isn’t a direct factor that lowers what you can see; it’s a traffic behavior, not a specific visibility hazard like spray.
