Solo, in training camp with the national team at the time, was with Stevens when he was pulled over. She was suspended by U.S. Soccer for 30 days and was reinstated on Saturday.
Solo spoke to ABC in an interview to be broadcast on Wednesday.
In excerpts published in advance of the interview, Solo said: "Well, clearly, I wasn't thinking. I mean, it was a horrible choice."
Solo also addressed the January dismissal of domestic violence assault charges against her, stemming from a confrontation with her half-sister and nephew at a party last June.
