Why You Should Always Tie Down Your Load

In many places it's illegal to drive around with anything in the back of a truck that isn't properly secured. As you can see from the completely horrifying video below, there's a good reason for that.

The guy is driving along in his car and was using the video function on his iPhone's camera, not a camera mounted to his dash. The guy said he was documenting two trucks hogging both lanes of traffic while driving about the same speed, creating a long line of cars behind them. Ultimately, he caught on video a 2x4 flying off the truck in front of him and skewering his windshield. Had the piece of wood struck a little higher and to the left, the video might have been evidence in a negligent homicide trial.
