First and foremost, I think you should consider shopping around
for a new company. Although "not at fault" accidents can have a negative impact
on your rate, that certainly seems like an exorbitant increase. The thing that makes the increase so severe is your daughter's age. If you or your spouse were involved in the accident I don't think the increase would be as significant. You might be able to save on your premium by testing the waters and quoting with as many companies as possible to find the best option.
