Difficulty: EasySpace Below

Running over road debris poses little danger to commercial vehicles because their high chassis clearance prevents objects from damaging undercarriage components.

Answer: Answer

Answer

False
The statement is false because running over debris is a serious hazard for commercial motor vehicles. Exposed undercarriage parts—including air brake hoses, electrical lines, and fuel tanks—can be torn loose, punctured, or severed by road debris.

Step-by-Step Solution

1
Identify the critical systems located beneath a commercial vehicle's frame.
The undercarriage houses exposed and essential components, including air brake lines, brake chambers, fuel crossover lines, wiring harnesses, and fuel tanks.
Recognizing what components exist in the space below determines the vulnerability of the vehicle to ground-level hazards.
2
Evaluate the mechanical impact of striking roadway debris such as tire fragments, wood, or metal scraps.
Debris can bounce, get caught in axles, puncture fuel tanks, sever brake air lines causing brake system failure, or become lodged near the exhaust system and ignite.
High ground clearance does not prevent loose objects from hitting and damaging exposed components.
