What is the required visual acuity in each eye for a school bus driver?

For a school bus driver, the required visual acuity in each eye is 20/40. This standard ensures that drivers have sufficient vision to safely operate a school bus, allowing them to effectively detect hazards, read road signs, and respond to the behavior of children and other motorists.

Visual acuity is a measure of the eye's ability to distinguish shapes and the details of objects at a given distance. The 20/40 requirement indicates that a driver can see at 20 feet what a person with normal vision can see at 40 feet, providing a baseline level of visual capability that is critical for the safety of both the driver and the children being transported.

Higher visual acuity standards, such as 20/20 or even 20/30, may not take into account the practical functional needs of a bus driver, while lower standards like 20/50 would not adequately ensure the driver's ability to respond to visual stimuli necessary for safe driving.
