Double your dry-weather separation distanceThis was the right answer

Wet-road stopping distances are at least double those on dry roads. Increase the dry-weather gap by at least that amount, reduce speed to the visibility and allow further space for the actual large vehicle. Dipped headlights help others see you; do not assume a doubled gap is always sufficient.
