A shipper loads and secures your truck. Under the federal cargo-inspection rule, does that remove your responsibility before driving?
Correct answer: No. You must meet the applicable cargo-check requirements.
The driver must satisfy the applicable pre-driving requirements even if someone else loaded the truck. The rule does not require personally doing all loading. Specific sealed or impracticable-inspection exceptions must be considered separately.

A truck has driven for 3 hours but only 100 miles since its last cargo reexamination. There is no inspection exception. What is required?
Correct answer: Reexamine the cargo now; 3 hours has been reached.
The later-check triggers operate on a whichever-occurs-first basis. Three hours is enough to require reexamination even when the truck has not covered 150 miles.

Cargo has been loaded in a way that makes inspection impracticable. What distinction does the federal rule make?
Correct answer: The paragraph (b) inspection exception does not erase general cargo-safety duties.
Paragraph (b)(4) also addresses loads that make cargo inspection impracticable. The exception is limited to that paragraph, not a general authorization for unsafe cargo. Mere convenience is not the stated standard.

What does a manufacturer's gross vehicle weight rating, or GVWR, describe?
Correct answer: The specified loaded-weight rating of a single vehicle.
GVWR is a manufacturer-specified rating for the loaded single vehicle. It is not the scale-measured weight of the truck on a particular trip and should not be confused with a combination rating.

The truck and trailer have adequate weight ratings, but the coupling device is rated below the proposed load it must carry or pull. What should you do?
Correct answer: Keep the load within the coupling's capacity as well as the other ratings.
Coupling devices have their own pull and support capacities. Adequate ratings elsewhere do not upgrade a lower-rated connection. Match the actual loading to all relevant capacities.

Moving cargo far toward the rear leaves too little weight on the truck's front axle. Why is that unsafe?
Correct answer: The steering axle may be too lightly loaded for reliable control.
Rearward weight shifts can leave the front axle too light to steer safely. Balance requires adequate loading at the steering axle without overloading it.

What is the purpose of snug blocking secured against a piece of cargo?
Correct answer: To prevent the cargo from sliding in the restrained direction.
Blocking fits against cargo and is secured to resist movement. It is part of a properly designed securement arrangement, not a universal replacement for every other required device.

What are the two basic purposes of covering an open load described in the handbook?
Correct answer: Protect people from spilled cargo and protect the cargo from weather.
A cover can help prevent spillage and protect freight from weather. It does not automatically replace the restraints needed to stop the load from shifting or falling.

Why can hanging meat make a refrigerated truck especially unstable on a sharp ramp curve?
Correct answer: The suspended load can move and has a high center of gravity.
Suspended cargo can move and shift the vehicle's balance. Hanging meat also places weight high, so particular caution is needed on tight ramps and curves.

Under the federal general cargo rule, how should an article likely to roll be restrained?
Correct answer: Use secured chocks, wedges, a cradle or an equivalent anti-roll method.
The anti-roll method must keep the article from rolling and must not become unintentionally loose or unfastened during transport. Its mere presence is not enough if it can move away.

A strap has a cut that reduces its securement performance. Can it be used merely because several undamaged straps are nearby?
Correct answer: No. A performance-reducing damaged component is not acceptable.
Securement devices must be in proper working order without damage that adversely affects performance. Other equipment does not make a defective component sound.

A tiedown has a 5,000-lb strap, a 3,300-lb tensioner and 4,400-lb anchor points. Assuming these are the relevant WLL ratings, what limits the assembly's WLL?
Correct answer: 3,300 lb, the lowest component or anchor rating.
The assembly is limited by the lowest component rating, including its tensioner, or the anchor-point rating, whichever is lower. Adding ratings or choosing the strongest part overstates the safe limit.

A tiedown with a 3,000-lb WLL runs from an anchor on the vehicle directly to an anchor on the cargo. How much does it contribute to aggregate WLL?
Correct answer: 1,500 lb.
A direct vehicle-to-cargo tiedown contributes one-half of its WLL to the aggregate. Here 3,000 ÷ 2 = 1,500 lb. This contribution is different from the tiedown's own rated WLL.

A load has the minimum number of tiedowns required for its length, but their aggregate WLL is too low. Is it adequately secured under the federal rules?
Correct answer: No. Minimum tiedown count and adequate WLL must both be met.
The minimum-number requirements apply in addition to the general securement requirements. Enough tiedowns by count is not enough if their properly calculated aggregate capacity is insufficient.

An article is exactly 10 feet long, not blocked against forward movement and covered by the general tiedown-count rule. What is the minimum count?
Correct answer: Two.
The two-tiedown length category includes articles longer than 5 feet and up to and including 10 feet, regardless of weight. The phrase 'including 10 feet' matters at this boundary.

An unusually shaped machine must be fastened by special methods and falls within 49 CFR 393.110(d). What does that exception mean?
Correct answer: The usual count formula does not apply, but the machine must still be securely fastened.
The special-purpose exception changes the application of the minimum-count formula. It does not remove the obligation to fasten the article securely and adequately or any other applicable requirements.
