This video reminds me of an incident that happened to me a few months back. A pickup truck coming toward me was pulling a home-made trailer (one of those made out of the bed of a pickup) - full of gravel. He lost control - and the trailer was tipping back and forth wildly like that yellow truck in the video. I was in a long line of cars and couldn't stop to get his license. Wheels of the trailer were leaving the ground on each side as it jerked back and forth!! WHEW. I saw in the rearview that the driver finally got control of it - and slowed WAY down. In the process, it was throwing its load of gravel out. I got sprayed - caused a broken windshield, broken headlight and running light, and chipped paint on front fender and hood of my car. $3,800 damage!
