What is one factor included in road/weather conditions?

Visibility is a critical factor included in road and weather conditions because it directly affects how well a driver can see the road, other vehicles, pedestrians, and obstacles. In adverse weather conditions, such as fog, rain, snow, or heavy cloud cover, visibility can be significantly reduced. This reduction can lead to greater risks of accidents as drivers may have difficulty judging distances and detecting potential hazards in time to react appropriately.

While traffic volume, road surface type, and driver behavior are important considerations in driving safety, they do not specifically fall under the category of road and weather conditions. Traffic volume pertains more to the amount of vehicles on the road at a given time. The type of road surface affects traction and handling, but it is not a weather-related factor. Driver behavior focuses on the actions of the individual behind the wheel, which, although critical, is influenced by the conditions but is not a condition itself. Thus, visibility remains a foundational element that encompasses how road and weather conditions impact driving safety.
