Howard Salmon has seen a lot on the highways in his semi truck – but no matter how experienced you are, you can’t be prepared for this.

While driving in Nebraska, Howard captured this scary footage of a shed flying in front of him. The shed materials had not been properly secured to a truck travelling ahead. When the driver reached a high speed, the items went soaring across the highway. Luckily they missed Howard’s vehicle. Credit: Howard Salmon via Storyful
