Answer:
Will rents a car while his car is in the shop.
Explanation:
If Will has his car in the workshop and has a Personal Auto Policy, then he can claim a temporary substitute while his car is being repaired.
A temporary subsititute is defined as an automobile that a person with an insurance policy uses in the interim when their vehicle is being repaired, has broken down, has suffered loss, or is being serviced.
Will borrowing a car while his own is in the shop is considered temporary substitution.
