Occurred on January 16, 2019 / Niles, Illinois, USA
Info from Licensor: "I was driving my truck when the two cars in front of me started swerving at each other before one car blocked the other completely. Since I was in the same lane where they stopped, they blocked me, but it gave me the opportunity to record what happened. The older guy came out of his car and started hitting the driver's side window with a knife. when he went back to his car, the younger driver came out of his car and started arguing and shouted at the older guy. The older driver came out of his car again."
