In what situations might a bus operator need to implement additional precautions for passenger safety?

Implementing additional precautions for passenger safety is crucial in various specific situations, particularly during bad weather, special events, or unusual traffic conditions. Bad weather, such as rain, snow, or sleet, can impact road traction and visibility, increasing the likelihood of accidents or difficulties in navigating the bus. During special events, there may be larger crowds or changes in regular traffic patterns, which can lead to increased risks for passengers boarding and alighting the bus. Unusual traffic conditions may involve unexpected road closures or detours, requiring the operator to adjust their route or driving style to ensure safety.

These scenarios call for heightened awareness and proactive measures to protect passengers, such as allowing extra time for boarding and alighting, driving at reduced speeds, or taking detours when necessary. The other options do not encompass the full range of circumstances where enhanced safety precautions are required, as they are either too limited in scope or overly reactive rather than preemptive.
