Why it matters: 3-second rule: greater following distance in rain, snow, fog and heavy loads
On the A20 near Moordrecht, where fog often rolls in over the Groene Hart and traffic drives close together, 3 seconds is exactly enough to compensate for the longer braking distance on wet or slippery road surface — without leaving so much room that others squeeze in. Too little margin costs you reaction time; too much margin costs you the traffic flow.
