I was riding behind a glass truck one day, went to pass on the left, and as soon as I did the truck hit a bump in the road and a huge sheet of glass fell off the left side. Must of been at least 8x6 like a storefront window. It shattered everywhere and I swerved just in time, looked over at the driver, he's looking in the mirror, and just keeps driving. I'm just glad I changed lanes when I did. I try to ride with nothing in front of me as much as possible, because I see unsecured loads too often. Shouldnt there be laws??
