Secure cargo requirements prevent cargo from leaking, spilling, blowing, or falling from a commercial vehicle. Regulations include minimum strength requirements for devices used to secure cargo, requirements that prevent cargo from moving, and rules for securing specific commodities. When commercial motor vehicles are used to transport cargo on public roads, they must be loaded and equipped, and their cargo must be secured, according to regulation.
See 49 CFR 393, Subpart I for full requirements on cargo securement.
