I have a personal injury and I'm filing on my personal insurance. I have their insurance company information, should I contact their insurance company

If you believe the other party is responsible for your accident, then you should either contact a lawyer to represent you in pursuing a lawsuit for your damages or contact the other party's insurance company to attempt a settlement on your own.  To learn more about what damages you may seek, visit Personal Injury Case Overview and click "What are damages?"
