What visual standard must a school bus driver meet?

A school bus driver must meet a visual standard of at least 20/40 in both eyes to ensure safety while driving and transporting students. This visual acuity standard is established to help ensure that the driver can see well enough to operate the bus safely, monitor the roadway and surroundings, and react appropriately to any hazards or situations that may arise. Meeting this requirement helps reduce the risk of accidents and enhances the overall safety of children being transported.

Although better vision may be beneficial, the established minimum is designed to ensure that all drivers can perform their duties effectively. Other levels of visual acuity mentioned in the options are either not aligned with the standards set for school bus drivers or lack the requirement for clarity in both eyes, which is crucial for depth perception and peripheral awareness when driving a large vehicle.
