Summer Internship car and insurance

My D will have an internship this summer, away from home, and will need a car. Her grandfather has a car that he wants to give to her (late grandmother’s car) permanently.

I imagine putting the car in her name and getting insurance would eat up a pretty good chunk of her summer earnings. I’m thinking we can transfer ownership to us (her parents) and put it on our insurance with her as the primary driver, out of state for the summer.

Anyone deal with this situation before?

She probably won’t take it to school afterwards - can I drop insurance for 9 months until she graduates?

Depends on your insurance company, zip code of residence, location of college, location of employer, number of cars.
