Car Accident Today

Ok guys i'm fine but I guess the car was considered totaled. I have a question here
the car was a rental and the officer said I was at fault which is fine. Now I did
have insurance with the car but since it was my fault the owner wants me to pay for the damages.
Now i'm not the smartest guy there but I thought full coverage insurance covers everything?
It.s bad enough I have a 90 dollar ticket to pay I don't want to have pay anything else. Sorry
to bug you guys just had to ask this.
