Should our insurance pay pain and suffering even though my husband was drinking?

Husband had motorcycle accident. He had been hit by another vehicle that was never identified but also ran over by another car, and that driver was identified. My husband had been drinking and charged with a DUI.The driver that hit him was never identified. The driver that ran over him; his insurance would not pay because my husband had been drinking. Our insurance paid so much on the motorcyle but never gave him any insurance money for his injuries. Aren't they still supposed to give him money for pain and suffering? This happened 4 years ago and we never got a lawyer, but we need to know our rights.
