85. When is an insured considered to be driving a temporary substitute automobile?

Answer: B

Explanation:

An insured is considered to be driving a temporary substitute automobile when borrowing a friend's vehicle while their own automobile is being repaired.

Borrowing a friend's vehicle while their own automobile is being repaired fits the definition of a temporary substitute automobile, as it provides a temporary solution during the period their primary vehicle is not available.

A) Driving their newly acquired automobile home from the dealership

This option does not qualify as a temporary substitute automobile because the insured is taking possession of a newly acquired vehicle, which is not a substitute for their own vehicle but rather a new primary vehicle.

B) Borrowing a friend's vehicle while their own automobile is being repaired

This option accurately represents a situation where an insured is using a temporary substitute automobile. It is specifically designed to cover scenarios where the insured's regular vehicle is temporarily out of service, making it a valid choice.

C) Using their secondary automobile while their primary vehicle is being serviced

While this option involves using another vehicle, it does not represent a temporary substitute automobile as defined in insurance terms. A secondary automobile is already owned by the insured and not a temporary solution for a primary vehicle that is unavailable.

D) Renting a vehicle for a road trip to avoid adding excess mileage on their own vehicle

Renting a vehicle for leisure purposes does not qualify as a temporary substitute automobile because it is not used as a replacement for a vehicle that is being repaired or is otherwise unavailable. This scenario describes a choice made for convenience rather than necessity.

Conclusion

Option B is the definitive correct answer because it describes a situation where an insured must temporarily rely on another vehicle due to their primary vehicle being out of service. The other options either involve the use of a primary or secondary vehicle or do not meet the criteria for a temporary substitute automobile as per insurance definitions.
