In the video, he shouts through his daughter's front passenger side window: "2-1, 2-1, unlucky Jamie lad, 2-1 lad".
In footage, Carragher is seen winding down his auto window and spitting at another vehicle.
Former Liverpool defender was removed by Sky Sports after the video appeared on social media.
Carragher, 40, apologised to the family and later said his behaviour had been "unacceptable" although he insisted he had not seen the girl in the front of the vehicle.
The 32-year-old urged people to show "decency" after the former footballer was seen hurling saliva at the teenager and her dad, which has led to him being suspended by Sky Sports. I wish she wasn't involved.
"That devastates me more than anything".
Carragher also went on Sky News and discussed the video, saying it was a "moment of madness" and "a bad stain on me and my character, my career".
He was suspended by Sky Sports shortly before the interview, which said in a statement: "Sky takes this matter extremely seriously and strongly condemns Jamie's actions, we have made that clear to him in person today and suspended him from his duties".
He said his "biggest regret was that a young girl was caught up in the middle of the altercation".
'There's no doubt what I have done is disgusting, I apologise for it, ' said Carragher, who has a daughter the same age as the girl he spat at. Before spitting, the video shows the man brought up the score of a football match between the Manchester United and Liverpool teams; Carragher used to play for Liverpool.
Carragher said the incident did not represent "the real me". "I was a role model, people looked up to me", he said.
'But what I'd hope, not just for Sky, but the public... is that five seconds of madness will not take over everything from what I've done [in the past]'. "No excuses he's made a big mistake", tweeted former Manchester United star Neville.
"I've been on TV for 3 years with him and imo this isolated incident shouldn't stop us working together".
