At what point should a school bus driver pay special attention to weather conditions?

Paying special attention to weather conditions is essential for school bus drivers at any time the weather changes. Sudden shifts in weather can drastically affect driving conditions, visibility, and road safety. For instance, rain, fog, snow, or ice can create hazards that may not have been present moments before. A school bus driver must remain vigilant and ready to adapt their driving technique to ensure the safety of the students and others on the road.

The importance of monitoring weather conditions is underscored by situations where students are present and waiting at bus stops, as well as during emergencies. While heavy snowfall and emergencies indeed require extra caution, the key aspect of this question is the proactive approach to any changes in weather, allowing drivers to anticipate and respond effectively to variable conditions.
