Question 1

What does 'freight density' mean in the context of load planning?

Accepted Answer

The weight of freight per cubic foot of space it occupies

Answer

Freight density is calculated as weight divided by cubic volume (lbs per cubic foot), which is used to determine freight class and the appropriate trailer type.

Question 2

Which loading method places the heaviest freight toward the front of the trailer near the cab?

Accepted Answer

Nose-loading method

Answer

Nose-loading places the heaviest freight at the front (nose) of the trailer to properly distribute weight over the tractor's drive axles and prevent rear axle overloading.

Question 3

What is 'headhaul' in trucking terminology?

Accepted Answer

The primary outbound load moving away from the carrier's home terminal in a profitable direction

Answer

A headhaul is the primary, typically higher-paying outbound load moving away from the carrier's home base, as opposed to the backhaul which brings freight back.

Question 4

What is the maximum legal weight on a single axle under federal US highway law?

Accepted Answer

20,000 lbs

Answer

Federal law caps single-axle weight at 20,000 lbs; tandem axles have a combined limit of 34,000 lbs, and total GVW is capped at 80,000 lbs.

Question 5

What is the purpose of sliding the tandem axles on a semi-trailer?

Accepted Answer

To redistribute cargo weight across axles and comply with legal axle weight limits

Answer

Sliding the tandem axles repositions the trailer's rear axle group forward or backward to shift how weight is distributed across axles and bring individual axle weights within legal limits.
