What should a driver do when driving a school bus in high wind?

When driving a school bus in high winds, maintaining a strong grip on the steering wheel and being prepared for gusts is crucial for ensuring safety. High winds can cause sudden and unpredictable changes in the bus's trajectory, and a firm grip allows the driver to maintain control. Anticipating gusts means being alert to potential pushes or pulls from the wind, which is especially important given the height and surface area of a school bus, making it more susceptible to wind effects.

In contrast, the other options would not lead to a safe outcome. Speeding up could make the situation more dangerous by increasing instability and reducing reaction time to external forces. Stopping and waiting for the wind to die down could be impractical and pose risks if the bus is on a roadway, as other vehicles may not anticipate the sudden stop. Lowering the windows to alleviate pressure is not an effective or safe solution, as it can create additional turbulence inside the bus, further complicating steering and control. Therefore, option B is the most appropriate and enables the driver to navigate safely through windy conditions.
