Some common scenarios where someone might be interested in temporary car insurance include:

Borrowing a vehicle
Renting a car
Test driving a vehicle
Moving or traveling
Sharing driving responsibilities
Putting a vehicle in storage

Note that, while temporary car insurance may seem like an attractive option, it might not be the best, depending on your situation. A vehicle in storage, for instance, can still be exposed to risks, like vandalism, theft or damage from a falling object. In which case, a better alternative might be to suspend certain coverages – like, collision coverage, for example – while keeping a protection like comprehensive coverage, which guards against certain incidents while your vehicle is in storage or parked.
