What can be done if the state is saying she has to purchase SR22 insurance but all this time she had regular insurance with State Farm?

In cases in which a person has had their driver's license suspended for an alcohol related arrest, the State of Washington will require that they make an SR22 insurance filing. This requirement runs for at least 3 years from the date they are eligible to get their license back, following the suspension. This is not necessarily new or different insurance, but simply proof of "future financial responsibility". It is filed by your insurance company. Most insurance companies do it, and should know just what to do. Some companies do not do them, so she will need insurance from another company that does.
