Should the safety distance be increased when there is fog?
A)Distance does not affect stopping when there is fog.
B)No, if the lights are on.
C)Yes, to have more space to react to any braking by the vehicle ahead.Correct
When driving in fog, the separation or safety distance should be increased. This provides more space to react to any braking, speed reduction or manoeuvre by the vehicle ahead, since it must not be forgotten that only the rear lights of the vehicle in front are visible, but not the road nor the obstacles or traffic situations that its driver encounters.
