Question

A broken exhaust system is dangerous because:

a) Exhaust noise will damage the driver's ears.
b) Toxic fumes and gases could enter the cab or sleeper berth.
c) The leaking exhaust smoke pollutes the air.
d) It can cause the vehicle to overheat.

Answer 1

A broken exhaust system is dangerous due to the infiltration of toxic fumes and gases like carbon monoxide into the vehicle's interior, similar to secondhand smoke, and it impairs the catalytic converter's ability to reduce emissions.

Step-by-step explanation:

A broken exhaust system is dangerous primarily because toxic fumes and gases could enter the cab or sleeper berth, posing a significant health risk to the occupants. When the exhaust system of a vehicle is compromised, harmful substances such as carbon monoxide (CO), nitrogen oxides, and unburned hydrocarbons can seep into the interior spaces, where they can be inhaled by passengers.

This is akin to the risks associated with secondhand smoke, which also contains harmful substances that can compromise human health. Furthermore, the catalytic converter plays a crucial role in converting these harmful emissions into less dangerous substances, but a broken exhaust system may prevent it from doing its job effectively, exacerbating pollution and negative health impacts.
