Probably an illegal.
Likely driving without a valid drivers license or insurance.
When my daughter was 17, her car was hit by a car driven by a Spanish speaking women. Luckily it was a very minor accident, my daughter was not hurt.
The women did not have a drivers license or insurance. My daughter was shaken and young and naive. She got the woman's phone number and address from another document she had. They turned out to be phony.
Our insurance company could do nothing.
