When driving in fog, what is the maximum speed limit set?

  1. 10 mph

  2. 20 mph

  3. 25 mph

  4. 30 mph

The correct answer is: 30 mph

When driving in fog, the maximum speed limit may vary depending on the state or city laws. However, it is generally recommended to reduce your speed significantly to allow for better visibility and reaction time. Option A, 10 mph, may be too slow and potentially hazardous if other cars are traveling at a higher speed. Option B, 20 mph, may still be too fast and could result in a collision if you need to suddenly stop. Option C, 25 mph, is closer to the recommended speed, but option D, 30 mph, is the most appropriate choice as it allows for a reasonable speed while also taking into consideration the increased risk and decreased visibility of driving in fog. Remember to always adjust your speed for the current conditions on the road to ensure everyone's safety.
