Alright, I can help you out with this one.
First, Geico shouldn't find out about her DWI until they run her record. They normally only run her record if you change your insurance policy or make a claim. MAKE SURE YOU DON'T ALTER YOU POLICY.
Now, I am not sure if you are going to have to file for SR-22 insurance or not. If you need SR-22 insurance to get her license back here is what you do: Call around to Allstate, Progressive, etc and get her the cheapest liability plan you can get (while keeping her on the current Geico plan).
In the long run this is going to save you at least a couple thousand.
Now, if she does get in an accident or need to make a claim, you can still do it through Geico (they have to by law). However, if you make a claim Geico will most likely drop you and you will probably need to get collision insurance somewhere else.
Good luck, you guys will get through it.
I live in Nassau Country New York. I reported my wife missing because she did not come home. The police came to my home and told me she was arrested for dwi. I was furious she called a lawyer instead of me. I put my wife and her car on my Geico Policy. I have a clean record for years. My first question is will they drop me? Can I have her sign over her car to me and remove her completely from insurance? This is her second DWI. The first one she got was 13 years ago. Is it best to take her off my insurance and once her license is restored have her get her own insurance. What is the best thing for me to do and since this happened yesterday how long before they find out? There was no accident.
