== Cargo Securement (393.100 – 393.136) ==

=== Working Load Limit (WLL) Calculations ===
* '''[[393.108]]''' – Working load limit for tie-downs chart. Tie-downs in general must secure half the actual load weight (Verify via shipping papers).
# A tie-down that goes over or through from the left anchor to the right side anchor is given the full working load limit of the weakest link.
# If a tie-down goes from the left side of the trailer, through the load, and back to the left side, it gets half the working load limit of the weakest link (Same for a left-side tie-down attached to the trailer directly to the load that is reliant on a right-side tie-down to keep it secure).

=== Minimum Number of Tie-Downs Required ===
* '''[[393.110]]''' – Quantity minimums.
* '''Unblocked Cargo:''' If not blocked by a header, bulkhead, or other cargo, a penalty strap applies. This requires 2 tie-downs within the first 10 feet and 1 within every additional 10 feet (or fraction thereof).
* '''Blocked Cargo:''' If all pieces of cargo are physically blocked by a header, bulkhead, or other cargo, it requires 1 tie-down within every 10 feet.
