Human Factors
I had just finished pushing back Aircraft X and as I was backing up a [ground service truck] sped by despite my wing walkers telling them to stop. He was going over the speed limit and was paying no attention to his environment. He was traveling at a very high dangerous speed. I had to slam on my brakes to prevent collision.
