What might be a potential issue with the posted speed for a turn?

The posted speed for a turn can present a potential issue if it is deemed unsafe for a bus. Buses are larger and heavier than standard vehicles, which means they may require a greater turning radius and may not be able to maintain stability at certain speeds. A speed that is appropriate for smaller vehicles may not take into account the dynamics and handling characteristics of a bus, especially when loaded with passengers.

This consideration of safety is crucial because excessive speed through a turn can lead to tipping, loss of control, or other hazardous situations. Therefore, it is important for drivers of buses to recognize that they might need to approach turns at reduced speeds, even if the posted limit seems appropriate for other vehicle types. The focus on safety ensures that both passengers and other road users are protected.

Choosing the posted speed as an absolute limit disregards the specific operational requirements of buses, which could lead to unsafe driving conditions. Similarly, while a speed might seem too slow for a bus, this does not directly address the potential hazards in relation to turn advisories, and stating it as absolutely safe overlooks individual vehicle characteristics.
