Why does dense fog affect traffic?

Answer and explanation

Correct answer: Because visibility decreases greatly

Correct answer: A, because visibility decreases greatly. Fog consists of countless tiny water droplets suspended close to the ground. These droplets scatter light and make distant objects, road signs, lane markings, pedestrians, and other vehicles difficult to see. Drivers therefore have less time to notice hazards and judge distance or speed safely. A is correct because reduced visibility is the direct traffic problem caused by dense fog. B is incorrect: fog does not physically lift or change the level of a road. C is incorrect: fog does not alter the mass or weight of vehicles. D is incorrect: gravity continues to act in foggy air. Safety and memory cue: fog means suspended droplets and poor visibility, so drivers must slow down and use appropriate lights.
