* Size of the bus: Larger buses have larger turning radii.
* Wheelbase: The distance between the front and rear axles. A longer wheelbase means a larger turning radius.
* Type of steering axle: Different steering mechanisms can affect turning radius.
* Manufacturer: Even within similar size classes, manufacturers may have slightly different designs affecting turning radius.
To find the turning radius of a *specific* school bus, you would need to consult its specifications, often found in the owner's manual or on the manufacturer's website. You might also be able to find this information on the data plate affixed to the bus itself. Expect the turning radius to be significantly larger than that of a typical car, likely in the range of 30-45 feet or more.
