When riding a moped on a wet roadway, what effect does water have on braking distance?

Question

DentroTest · Accepted Answer

Water creates a liquid film between the tire and the road surface that noticeably reduces grip. With less friction, the braking distance (the distance the moped travels from the moment the brakes are applied until it comes to a complete stop) gets longer and can become twice as long as on a dry roadway. On mopeds this factor is even more critical because of their lower stability and greater risk of skidding or falling, so it is advisable to increase the safety distance from the vehicle ahead and to brake early and progressively. Saying that there is hardly any difference from a dry road surface is false, and so is saying that you brake better because the tires are cooled: water reduces grip; it does not improve it.
