A 20-foot article is blocked or immobilized against forward movement. What is the minimum number of tiedowns required under the general length rule?
Correct answer: D – 2
Federal cargo-securement rules require at least one tiedown for each 10 feet, or fraction of 10 feet, when an article is blocked or immobilized against forward movement. A 20-foot article requires two tiedowns. If the article is not blocked against forward movement, a different rule applies and three tiedowns would be required for that length.
