The first step in the new securement rules is to have a thorough understanding of the rules. All motor carriers operating in interstate commerce must be in compliance with the new requirement effective January 1, 2004. The new rules, which are based on the North American Cargo Securement Standard Model Regulations, require motor carriers to change the way they use securement devices so that their cargo is less likely to shift within the trailer or fall from the vehicle. The goal of the new securement requirements is to reduce the number of truck accidents that are caused by falling or shifting cargo.
