What is the standard maximum gross vehicle weight (GVW) for a 5-axle semi-truck on US interstate highways without a special permit?
Answer: 80,000 lbs
Federal law limits standard 5-axle semi-trucks to 80,000 lbs GVW on US interstates; exceeding this requires an overweight permit.
When planning a load, what does it mean when a trailer has 'cubed out'?
Answer: The trailer's cubic volume is full before the weight limit is reached
Cubing out means the trailer runs out of usable space (volume) before reaching its legal weight limit, so volume rather than weight is the binding constraint.
What is the primary purpose of load sequencing in a multi-stop delivery route?
Answer: To ensure freight is loaded in reverse order of delivery stops
Load sequencing places freight in reverse delivery order so the first stop's freight is loaded last and is at the rear door, making it immediately accessible upon arrival.
Which factor is MOST critical when determining whether a load requires a flatbed rather than a dry van trailer?
Answer: The freight's dimensions and loading requirements
Whether freight fits inside an enclosed trailer and can be dock-loaded determines flatbed necessity; oversized, crane-loaded, or irregularly shaped freight typically requires a flatbed.
What is a 'drop and hook' load in truck dispatching?
Answer: A load where the driver drops a trailer and picks up a pre-loaded trailer without waiting
In a drop and hook arrangement, the driver leaves their current trailer and immediately hooks to a pre-loaded trailer, eliminating detention time at the facility.
When optimizing a backhaul, what is the dispatcher's primary goal?
Answer: Secure revenue-generating freight for the return trip to avoid deadhead miles
Backhaul optimization seeks freight moving in the return direction to eliminate costly empty (deadhead) miles and generate revenue on both legs of the trip.
What is the maximum legal combined height for a truck and cargo in most US states without a special oversize permit?
Answer: 13 feet 6 inches
Most US states set the maximum legal height at 13 feet 6 inches (162 inches) for the combined height of vehicle and cargo; exceeding this requires an oversize permit.
