In general, one securement device is required for every 10 feet of length or fraction thereof.

  • There must be enough securement devices (i.e., chains, straps, etc.) to cover half the weight of the cargo, based on the working load limit of the securement devices and how they are attached to the transport vehicle.
  • Additionally, cargo must be secured for length.   If the cargo is not against a front-end structure or other equivalent device, one additional tie-down is required for the first 10 feet of length.  There are additional commodity specific cargo securement rules found in 49 CFR §393.116 § 393.136.
