Kid - traffic accident - Texas how's this work?

Sorry, not my child. Child of good friend who called me because I used to do contracts for a public finance firm so she thought that meant I know the law. Insurance has already been contacted and stated they'll be handling payment of the damage to other car. Friend has no problem with what is due being paid to the owner of the other car, just has concern they may try to get more than their fair share. I have explained I don't know anything about traffic law just because I do contracts, but she keeps calling me because she's scared, so I asked for info here. We have already determined surely cop knows whether kid has to show up in court, and kid will show up. According to the directions on several websites for various court houses, there will be more than a fine in Texas because this is someone under 25. None specify exactly what all might the addition be and that's what we want to know mostly. Teen is very scared, too, and we'd just like to prepare teen a little for court.

For anyone reading this, so it turned out in fact the police officer did get it completely incorrectly. Although the officer instructed specifically that 16 year old's have to have parent or guardian with them in court but a 17 year old doesn't have to bring their parents, in fact parent or guardian must accompany 17 and younger. It is even printed on the back of the ticket in really tiny, hard to read print. Parents were told this is state law in Texas. Although there were reports to the contrary on other websites, at least in some cities, there is no further difference between how a teen is treated and how an adult is treated when they receive a ticket.
