What type of equipment is NOT included in the "auto" definition of the Business Auto Policy?

The correct choice regarding what type of equipment is not included in the "auto" definition of the Business Auto Policy is tractors. In the context of this policy, "autos" generally refer to vehicles designed for transporting people or property on public roads, which typically includes light-duty trucks, buses, and motorcycles.

Tractors, while they do have wheels and an engine, are primarily designed for agricultural purposes rather than for use as transport vehicles on public roads. They do not fit the standard definition of "autos" under the policy, which is more focused on vehicles used for business activities that involve public or customer access. This distinction is crucial because businesses often need different types of coverage depending on the specific vehicles and their intended use; hence, a tractor would fall outside the realm of what is typically insured by a Business Auto Policy.
