What is an aggregate load?
- A load that does not fill your vehicle completely
- A load that is too large for your vehicle to safely carry
- The combined weight of the vehicle and its load
- A load composed of a collection of small articles ✓
Answer: D. A load composed of a collection of small articles
An aggregate load is a load composed of a collection of small articles.
Why this is the answer
The handbook defines an aggregate load as a collection of small articles, and gives sand, gravel, paper pieces, and wood chips as examples. It also says that if these small pieces can’t be held by sideboards or tiedowns and are likely to bounce, blow, or drop off, you need a cover or tarp. The choice about a collection of small articles matches that definition directly; the other choices describe different loading situations.
Why the other answers are wrong
- A. A load that does not fill your vehicle completely — A partly filled vehicle is not what the handbook calls an aggregate load; the term is about the kind of small articles making up the load, not how full the vehicle is.
- B. A load that is too large for your vehicle to safely carry — An oversized load that the vehicle cannot safely carry is a size problem, while the handbook’s aggregate load definition concerns a collection of small articles.
- C. The combined weight of the vehicle and its load — The combined weight of the vehicle and its load is a weight measure, not the handbook’s meaning of aggregate load.
Remember it
Picture a dump truck full of gravel or wood chips: many small pieces together are an aggregate load.
