A covered interstate truck carries ordinary crates inside a closed body. Why do the crates still need adequate restraint?
Correct answer: A closed body alone does not prove the cargo cannot move inside.
General securement addresses movement within a vehicle as well as cargo falling off it. Use suitable vehicle structures, blocking, tiedowns or other adequate restraint.

A tiedown has visible damage that could weaken it. What is the appropriate decision before departure?
Correct answer: Replace or correct the deficient securement component.
Securement components must be capable of doing their job in their present condition. Damage that adversely affects performance is not cured by an old rating or by concealing it.

A web tiedown bears against a sharp crate edge that could cut it. What additional protection is needed?
Correct answer: Suitable edge protection that resists cutting, abrasion and crushing.
Where contact could abrade or cut a tiedown, appropriate edge protection is needed. Its material must withstand the loads and contact, not merely cover the edge visually.

A hook can unfasten as the load vibrates, although the strap was tight when parked. What needs correction?
Correct answer: The attachment must prevent unintended loosening or release in transit.
A tiedown must remain attached and secured while the vehicle moves. A connection that can open or release under normal movement is not made adequate by initial tightness.

A truck's tiedowns pass outside its rub rails. Does that position alone establish a violation of the current federal tiedown-use rule?
Correct answer: No; the securement must still satisfy strength, attachment and protection requirements.
The current federal tiedown-use rule does not make outside rub-rail routing alone a violation. This does not approve an unsafe arrangement: tiedowns must satisfy strength and attachment requirements and use edge protection where cargo contact could cut or abrade them.

A cylindrical article can roll across the deck despite being prevented from sliding lengthwise. What else is required?
Correct answer: Chocks, a cradle or equivalent restraint against rolling.
Preventing one type of movement is not enough if the article can roll. Suitable rolling restraints must themselves remain secure during transportation.

Two articles share transverse tiedowns but have a gap between them. What must prevent them from shifting toward each other?
Correct answer: Adequate restraint, or positioning them in direct contact.
Adjacent articles under transverse tiedowns must touch or be kept from shifting together. Otherwise movement into the gap can change the effectiveness of the securement.

Why might an appropriate dunnage bag be used between cargo and a vehicle wall?
Correct answer: To fill a space and help restrain or protect the cargo.
Suitable dunnage can support, protect and help immobilize cargo. A bag must be suitable for its role; its presence does not repair other defective securement components.

Under the cited general rule, a securement system restrains a 6,000-pound ordinary article. What aggregate working load limit is required at minimum?
Correct answer: 3,000 pounds.
The aggregate working load limit must be at least half the article's weight. Half of 6,000 pounds is 3,000 pounds; tiedown configuration and other requirements still matter.

A load meets the minimum tiedown count, but the system's aggregate working load limit is insufficient. Is the load adequately secured?
Correct answer: No; the working-load-limit requirement must also be satisfied.
Minimum count and minimum aggregate strength are separate requirements. Meeting one does not excuse failing the other or using damaged equipment.

An ordinary 4-foot crate weighs 900 pounds and is not blocked against forward movement. Under the general count rule, what is the minimum number of tiedowns?
Correct answer: One, provided the other securement requirements are also met.
An unblocked ordinary article no longer than five feet and no heavier than 1,100 pounds has a one-tiedown minimum under this rule. That count does not waive working-load-limit or adequate-restraint requirements.

An ordinary 4-foot crate weighs 1,500 pounds and is not blocked forward. What is the general minimum tiedown count?
Correct answer: Two.
The crate is within five feet but exceeds 1,100 pounds, so the general rule requires at least two tiedowns. The securement must also provide adequate strength and prevent movement.

An ordinary 8-foot article weighs only 600 pounds and has no forward blocking. What is its general minimum tiedown count?
Correct answer: Two, despite the relatively low weight.
For an ordinary article in this length range, low weight does not reduce the general two-tiedown minimum. Count, strength and securement effectiveness must all be considered.

An ordinary 21-foot article has no forward blocking and is not subject to a special securement method. What is the general minimum tiedown count?
Correct answer: Four.
The rule uses two tiedowns for the first ten feet, then one for each further ten feet or part of ten feet. The remaining eleven feet requires two more, for a total of four.

An ordinary 21-foot article is properly blocked against forward movement. Under the general count rule for that arrangement, how many tiedowns are required at minimum?
Correct answer: Three.
For a properly forward-blocked article, the general rule calls for at least one tiedown for each ten feet or fraction of ten feet. Twenty-one feet spans three such intervals.

A crate is merely near another loose crate. Can the first crate be treated as adequately blocked forward on that fact alone?
Correct answer: No; the blocking arrangement must actually prevent forward movement.
Forward blocking must be effective. Another article can serve that role only when the arrangement actually prevents movement; loose cargo nearby does not establish adequate blocking.

A driver is loading cargo covered by a more detailed commodity-specific securement rule. Is compliance with the general rule alone enough?
Correct answer: No; applicable additional commodity-specific requirements also matter.
Commodity-specific provisions can prescribe extra or more detailed securement. Check the requirements for the actual cargo rather than assuming a general count settles the entire question.

Bulk liquid carried in a structural tank is outside these article-securement rules. Does that statement establish that its transportation has no other safety requirements?
Correct answer: No; that exclusion is limited to these article-securement provisions.
The cited exception concerns shapeless bulk material in the appropriate structural containment. It does not erase other vehicle, tank, loading or hazardous-material requirements that may apply.

An unusually shaped structural item requires a special fastening method. What remains necessary even when the ordinary tiedown-count rule does not apply?
Correct answer: A securement system adequate for the item and the applicable requirements.
The special-purpose provision does not make an unusual article exempt from adequate securement. Its fastening system must still be suitable and meet the applicable performance and strength requirements.

A round load is supported by wedges that could shake loose on the road. What must be corrected?
Correct answer: Secure the rolling restraints so they cannot unintentionally release.
Rolling restraints must keep working throughout transport. A restraint that can become loose or unfastened does not reliably prevent the load from rolling.
