What should a bus operator do if visibility is significantly reduced while driving?

When visibility is significantly reduced while driving, the best course of action for a bus operator is to slow down and increase following distance. This approach enhances safety by allowing the driver more time to react to any obstacles or hazards that may arise. Reducing speed helps in managing uncertainty in visibility conditions, as it gives the operator a better chance to make careful observations of the surroundings.

Increasing the following distance is also crucial during reduced visibility. It allows for adequate space to stop safely without risk of a collision, should the vehicle in front suddenly slow down or stop due to unforeseen circumstances. This ensures that the bus operator maintains control of the vehicle and enhances the safety of passengers and other road users.

Maintaining a cautious and responsible driving approach is essential in challenging visibility conditions, as speeding up or using high beams cannot compensate for the dangers posed by limited sight. The use of the horn, while it may alert others, does not address the core issue of navigating safely in low visibility situations. Thus, slowing down and increasing following distance is the most effective and responsible choice for a bus operator in such circumstances.
