Final answer:
The Employee Non-Owned Auto Protection endorsement provides coverage for employees using their own cars for business purposes under a Business Auto Policy.
Step-by-step explanation:
The Business Auto Policy endorsement that covers employees while using their personal cars for business purposes is known as Employee Non-Owned Auto Protection. This endorsement is an addition to the business's commercial auto policy and extends the coverage to include vehicles that are not owned by the company but are used by employees for conducting business activities. It is essential for businesses whose employees use their own cars for work-related duties, as personal auto policies typically exclude business use.
