What should I do?

Don't mess around, file the reports, get looked at.
This **** can come back and bite you in the ***.
If the tow truck driver was injured by your companies
truck no matter who's fault, lawyers will go after everyone
involved to get into the money.
You could end up in a civil suit with no recourse but to lawyer up
at your expense, not to mention your possible injuries that will come out of our pocket and medical ins later if you don't do the paperwork now.
