When driving in the rain, is it necessary to increase the safety distance regarding the vehicle ahead?

Question

DentroTest · Accepted Answer

Yes, it is essential. When it rains, water forms a film on the asphalt that drastically reduces tire friction, causing grip (adherence) to decrease. This causes the braking distance to increase (generally double that of dry conditions). Therefore, to avoid rear-end collisions, the separation from the vehicle in front must be extended. This is a safety rule applicable to all roads (urban and interurban), invalidating options suggesting it is unnecessary or only applies outside built-up areas.
