So in the video, the guy points out that the flatbedder incorrectly secured the pallets of singles. He says each stack/pallet should have two straps instead of one. He argues that this is FMCSA regulation, specifically, this:

When an article of cargo is not blocked or positioned to prevent movement in the forward direction, the number of tiedowns needed depends on the length and weight of the articles. There must be - one tiedown for articles 5 ft or less in length, and 1,100 lbs or less in weight; two tiedowns if the article is -

- 5 ft or less in length and more than 1,100 lbs in weight; or

- greater than 5 ft but less than 10 ft, regardless of weight.

It's 49 CFR 393.110 (b) in the regulations. A lot of commenters are saying he's dead wrong. But I think he's right. I'm not a flatbedder, but I might be soon and looking to learn. Thanks!
