I was in a work truck following another fellow employee. It was on a residential street in kansas. I was doing between 5-10mph in a 25. I had 2-3 seconds between me and the other truck. He came to an unexpected sudden stop. At the same time he hit his brakes, a locust flow into my truck hitting me in the face. This startled me and I was distracted long enough that I couldn't stop in time. No damage to the truck in front of me. Some minor damage to the truck I was driving. No police report or insurance claim. My boss called it carelessness and wants to put me on a probation period. I don't really see how that is carelessness. The locust was a distraction beyond my control. If it wasn't for the locust I would have been able to aviod the accident. Am I at fault?
