General Knowledge Practice Question 28

RequiredGeneral Knowledge · Question 28

The general rule for cargo tiedowns is at least one tiedown per:

• A20 feet of cargo
• B10 feet of cargo, with a minimum of 2
• C5 feet of cargo
• D1 tiedown total per truck

Correct answer: B. 10 feet of cargo, with a minimum of 2

Why: FMCSA's general securement rule requires at least one tiedown per 10 feet of cargo, with a minimum of two tiedowns regardless of length.
