School Bus Stop Incident

Hey Houston, I was involved with a minor incident where no violation occurred. I was driving and on a perpendicular street where a school bus stopped. I didn’t notice the stop arm from the angle I was driving. The driver honked and I stopped. She appeared overly irritated and said I was sorry with my hands. At no point did I pass the bus while the arm was out. At the next stop sign when I was ahead of the bus I noticed them writing my license plate down in my rear view mirror. Again I don’t feel I broke any law and have a pristine driving record. If anything it was a good reminder to be more aware even though I stopped. Can I expect to get a ticket in the mail based on a bus drivers account if they report it? My understanding is no but would like someone else’s opinion. Thanks in advance.
