How does weather affect passenger transport?

Weather significantly influences passenger transport in various critical ways, with one of the most notable being its ability to reduce visibility and traction. In adverse weather conditions such as rain, fog, snow, or ice, drivers face challenges that directly impact their ability to see the road clearly and maintain control of their vehicle. Reduced visibility makes it difficult to notice traffic signals, pedestrians, or other vehicles, increasing the risk of accidents. Similarly, poor traction due to wet or icy roads can lead to skidding or losing control, prompting the need for increased caution and sometimes resulting in delays or accidents.

The other options do not encompass the comprehensive effects of weather on passenger transport. While weather may influence the interior temperature of a vehicle, this aspect is trivial compared to concerns about safety. The claim that weather has no significant impact overlooks the reality of how it alters driving conditions, increasing hazards on the roads. Lastly, although fuel efficiency can be affected by weather conditions, it is not the primary concern drivers face when navigating through inclement weather—a focus on safety and control takes precedence. Hence, the most relevant answer is that weather can indeed reduce visibility and traction, affecting the safety and efficiency of passenger transport.
