Question

Difficulty: EasySpace Below

A commercial motor vehicle loaded with heavy cargo has less ground clearance underneath than the same vehicle when empty.

Answer: Answer

Answer

True - A loaded commercial vehicle sits lower to the roadway because the added cargo weight compresses the suspension system, thereby reducing the space underneath the vehicle.
When a commercial motor vehicle carries a heavy load, the cargo weight compresses the suspension, reducing the total clearance between the ground and the underside of the vehicle.

Step-by-Step Solution

1
Analyze how added cargo weight interacts with a commercial vehicle's suspension system.
The added weight forces the suspension springs to compress under the load.
Vehicle suspension systems are mechanical springs designed to deflect under increased payload.
2
Determine the impact of suspension deflection on ride height and undercarriage clearance.
The chassis, axles, fuel tanks, and trailer undercarriage move closer to the ground.
Spring compression lowers the vehicle's frame relative to the roadway surface.
3
Evaluate the truth of the statement based on this mechanical behavior.
The statement is true because heavy cargo directly decreases space below.
A loaded truck or tractor-trailer consistently has less clearance underneath than an empty one.
