The other driver doesn’t have any insurance, what do I do now?

You would be able to use your uninsured/under insured motorist coverage if you have it.  This is a very complicated area of the law. Get a lawyer.  You’ll be glad you did.    The most important thing is to let your insurance company know you need to use your UM/UIM coverage in writing as soon as possible.  It is better to let an experienced attorney do this for you. They know how and where to do this.
