What is the main reason why we must increase the safety distance in case of fog?

Question

DentroTest · Accepted Answer

Fog is an adverse weather condition that drastically reduces visibility and often decreases tire grip by making the asphalt wet. Because we cannot see the road or obstacles far enough in advance, the driver takes longer to perceive danger. Therefore, increasing the safety distance (frontal interval) is vital to have more 'braking space' and reaction time in case of an unforeseen event. The other answers are incorrect: we seek to have more time to brake, not less, and we must pay maximum attention to road markings as a guide, never less.
