Giải thích
An article longer than 10 feet needs two tiedowns for the first 10 feet plus one more for each additional 10 feet or fraction, so a 12-foot article needs three. One tiedown is only allowed for articles 5 feet or shorter and 1,100 pounds or less, and four exceeds the minimum for this length.
