What must a vehicle's exhaust system meet to pass inspection?

1. It must be free of leaks and properly direct fumes away from passengers

2. It should be made of stainless steel

3. It must be the original manufacturer's exhaust system

4. It must produce no noise during operation

The correct answer is: It must be free of leaks and properly direct fumes away from passengers

A vehicle's exhaust system must be free of leaks and properly direct fumes away from passengers to pass inspection because this is crucial for both safety and environmental reasons. A leaky exhaust can cause harmful fumes, such as carbon monoxide, to enter the passenger compartment, posing serious health risks. Ensuring that exhaust fumes are directed away from the vehicle's occupants is essential for preventing exposure to these toxic gases. Additionally, a properly functioning exhaust system plays a significant role in controlling emissions, thus contributing to environmental protection standards. Meeting this requirement helps maintain safe air quality within the vehicle and complies with regulatory standards for vehicle emissions. While other factors such as construction materials, originality of the parts, or noise levels may influence a vehicle's exhaust system performance, they are not the primary criteria for passing an inspection regarding safety and proper function.
