My sister asked if I would add her to my car insurance as she would like to borrow it sometimes. I really don't mind doing it if she pays the extra but as she's a fairly new driver I am worried any accidents will send my renewal policy sky high.
Yeah, I don't really think that's a good idea. If she crashes your car, your rate will surely go up. Does she not have a car and her own insurance? If so, her insurance should cover her in any car she drives.
Boy, that sounds like a touchy situation. I'm not really sure what I would do, though I would not want to be stuck holding the bag in the event things turn badly.
