#AAAFoundationForTrafficSafety

Whether it’s a poorly tied-down college mattress taking flight like a ungraceful, soiled bird, or scrap metal launching itself out of a pickup bed after hitting a pothole, debris is piling up on U.S. roads, and drivers are dying because of it.

According to a study by the AAA Foundation for Traffic Safety, crashes caused by road debris rose 40 percent in the past 15 years. America’s loads have never been looser.
