From the details given, it sounds like she should bear some responsibility. But the story is lacking in details. Perhaps her coworker claimed to be sober and had not been visibly drinking at the work party. Perhaps she pleaded with him to slow down.

But if they had been involved in a car accident, should she bear some portion of blame? Definitely.
