Which orientation is described as advantageous because it is not damaged by low bridges or tree branches?

• A. Vertical exhaust system
• B. Horizontal exhaust system
• C. Both
• D. Neither

Answer: (B)

The main idea is how exhaust orientation affects exposure to overhead obstacles like low bridges and overhanging branches. A horizontal exhaust runs along the side or rear of the vehicle, staying low and out of the path of branches and overpasses. A vertical exhaust, sticking upward, is more likely to be struck by low-clearance bridges or protruding branches. Because the horizontal setup minimizes contact risk with those overhead hazards, it’s described as advantageous in this scenario.
