Wow, sorry to hear that and glad to hear she is OK. I have always carried more insurance than what is specified as "required", even keeping full coverage on cars I own outright. I think my new policy is 300K, but previously always had it at 150K.
Well you need to check for UM ie. Uninsured\UnderInsured coverage on your policy. Typically, you have to ask for it to be included as your agent does not make much return on the seperate UM policy.
We are from Florida and it is a no fault state. That allows what is called stacking of the policy limits. My 150 on each of my 5 autos would have offered 750 thousand in coverage. Well, when we moved to Texas my new insurance agent never informed me of the change. I guess I should have asked.
As for the girl that hit my wife. She did lose her car and spent some time in the hospital. However, I don't think she really understands what she cost us in the past year.
