Minor Bump? Do I list As A Safety Violation

Last January I was squeezing a bus through a tight gap that I had done multiple times in the past. I didn't set it up right and I ended up hitting the lug nuts of the bus against the lug nuts of a tow truck next to me. We didn't hit anything else, which I thought was interesting. Anyhow the tow truck had no damage, and the bus was missing some plastic lug nut covers. We didn't call the police but I filled out an accident report, gave him a copy and gave my boss a copy, and I was written up at my job for it. However since there was no damage to the other vehicle, and they never bothered replacing the lug nut covers I knocked off, how would I list it on an application. It costed no one a penny except for me, I lost .25 an hour for it.
