What must a school bus driver do if they cannot see clearly due to fog?

• A. Continue driving with caution
• B. Activate hazard lights and drive slowly
• C. Stop until visibility improves
• D. Proceed at normal speed

Answer: (C)

When visibility is significantly reduced due to fog, the safest and most responsible action for a school bus driver is to stop until conditions improve. This approach prioritizes safety, allowing the driver and passengers to avoid the risks associated with driving in low-visibility situations, such as decreased reaction time and difficulty seeing other vehicles or obstacles on the road.

Stopping when visibility is poor ensures that the driver can wait for clearer conditions, which is crucial for the safety of both the students on board and other road users. It also aligns with defensive driving techniques, which emphasize the importance of adjusting one's driving based on current environmental conditions. By ensuring that they have adequate visibility before proceeding, the driver can make more informed and safer decisions.

Other options may suggest continuing to drive—either with caution or hazard lights—but these methods still expose the bus, its passengers, and other motorists to unnecessary risk in conditions where visibility is critically compromised.
