Correct answer
greater than the distance you would keep on a dry road.
Increase the gap. Reduced grip can lengthen braking distance, so you need a larger margin to stop without collision. Adapt the gap to speed, actual grip, tyres, load, braking capability and visibility. No fixed multiplier guarantees safety on every wet road; any applicable additional or specific minimum distances must also be observed.
