In fog, why should you increase your following distance even more than you would in normal conditions?

Pick an answer

1. Reduced visibility means you may not see a hazard or stopped vehicle until you're already close to it
2. Fog reduces tire traction directly, so following distance is unrelated
3. Extra following distance is only needed in dense fog, not in a light mist, though the reality of conditions says otherwise
4. Fog has no effect on stopping distance, only on visibility of road signs
