In wet conditions with reduced visibility from spray, which following distance is recommended?

• A. Maintain a two-second rule.
• B. Increase to at least four seconds or more.
• C. Follow the vehicle in front closely.
• D. Use high-beam headlights.

Answer: (B)

When roads are wet and spray reduces visibility, you need a much larger following distance than on dry roads. Wet pavement lowers tire grip, so braking takes longer; spray limits how quickly you can see hazards, delaying your reaction. Giving four seconds or more of space creates enough time to detect the car ahead, slow gradually, and come to a stop safely if needed. A simple way to gauge it is to pick a fixed object ahead and ensure four seconds pass from the front vehicle reaching it to you reaching it. The other ideas don’t fit because a two-second gap isn’t enough in rain, following closely is unsafe, and using high-beam headlights doesn’t change your following distance and can glare other drivers.
